Direct answer: what does ClearPass configuration involve?
HPE Aruba Networking ClearPass Policy Manager is a network access control platform used to authenticate users and devices, evaluate context and apply role-based access decisions across suitable wired, wireless and VPN infrastructure. A configuration project usually connects ClearPass to identity stores and network devices, defines services and policy rules, maps identities or attributes to roles, builds enforcement profiles, validates RADIUS or TACACS+ communication, and tests expected access results. Organisations should consider it when they need more consistent control over who and what can connect. Before proceeding, confirm the exact ClearPass deployment, supported software release, licensing, endpoint scale, network-device compatibility, certificate strategy, identity sources and the required access outcomes.
What the service is designed to do
ClearPass configuration is not simply the act of entering an IP address and creating a RADIUS client. The objective is to turn business access requirements into an enforceable policy structure. That can mean authenticating employees to corporate Wi-Fi with 802.1X, restricting unmanaged devices, allowing printers or specialised endpoints through a controlled MAC-authentication workflow, separating guest access from internal resources, or authenticating network administrators with TACACS+ where the surrounding infrastructure supports the required method.
The work may include building authentication sources, service rules, role mappings, enforcement policies, enforcement profiles, network-device definitions, certificates, guest workflows, profiling inputs and monitoring practices. The exact combination depends on the licensed ClearPass capabilities, software version and the wider environment. FourTeck can help translate a requirement such as “employees should receive different access from contractors” into the identity attributes, network controls and test cases needed to make that policy reliable.
Who should consider a ClearPass configuration project?
The service is relevant to organisations already running ClearPass, deploying it for the first time, expanding it to new sites, or redesigning an access policy that has become difficult to manage. It can suit corporate offices, hospitality environments, campuses, healthcare organisations, education networks, logistics facilities, government environments and multi-site enterprises where users and devices need different levels of network access.
It is especially useful when the business has more than one identity type, more than one access method, or more than one enforcement outcome. A small environment with only a basic shared password may not need a full NAC design. A larger environment with employee certificates, contractors, printers, IP phones, guest access, role-based VLAN assignment, posture checks or privileged network administration normally requires more careful policy architecture and testing. FourTeck can review the current design before recommending the configuration scope.
Business access problems the configuration can help address
Unknown or inconsistent access
When different switches, wireless controllers or sites apply access differently, ClearPass can provide a central decision point for supported authentication and policy workflows. The design still depends on each network device being configured to request and enforce the required attributes correctly.
Mixed user and device populations
Employees, contractors, guests, corporate endpoints, BYOD and non-802.1X devices rarely need identical access. Policy rules can distinguish them using available identity, authentication and profiling information, with controls appropriate to the reliability of that information.
Manual network administration access
TACACS+ can be incorporated for supported network-device administration so organisations can apply central authentication, authorisation and accounting policies. Command-level behaviour and privilege mapping remain vendor and device dependent and must be tested.
Guest and onboarding complexity
Where licensed and required, ClearPass guest and onboarding workflows can help separate visitor access from internal identity processes and can support structured BYOD provisioning. Portal, certificate, sponsor and device-registration requirements should be agreed before build work begins.

Dependencies to confirm before configuration begins
ClearPass is positioned in the middle of several systems: network access devices send requests, identity stores answer identity questions, certificate authorities may establish device or user trust, enforcement endpoints apply the returned attributes, and monitoring tools may consume events. A problem in any one of these areas can look like a ClearPass problem even when the policy itself is correct. For that reason, a professional configuration scope should identify dependencies before the first production policy is changed.
Important items include software release support, appliance or virtual platform health, current licences and subscriptions, DNS and NTP, server certificates, trust chains, Active Directory connectivity, firewall rules, shared secrets, network-device RADIUS/TACACS+ settings, source-interface behaviour, CoA support where required, VLAN or downloadable role capabilities, supplicant configuration and client certificate deployment. Guest access may add public certificate, captive portal, email or SMS workflow requirements. Onboard and OnGuard capabilities are licence and design dependent. FourTeck can help document these prerequisites so implementation work is based on verified inputs rather than assumptions.
A practical ClearPass configuration journey
Discovery
Review the current network, ClearPass deployment, licences, identity sources, endpoint groups, authentication methods, site topology and business access rules. Existing policies are captured before changes are proposed.
Policy design
Convert requirements into services, authentication methods, role mappings, enforcement logic and fail-safe decisions. Define what should happen for successful, failed, unknown and exceptional access cases.
Build and integration
Create or adjust the ClearPass objects, network-device definitions and selected identity integrations. Changes to switches, controllers, VPN gateways or certificates are coordinated according to the agreed responsibility matrix.
Controlled testing
Use representative users and endpoints to validate intended access, denied access, fallback behaviour, attributes, accounting and operator visibility. Production deployment should follow successful test evidence.
Handover
Document what was configured, key dependencies, operating checks, rollback information and known exclusions. Optional knowledge transfer can help internal teams understand common troubleshooting paths.
Policy architecture that matches real identities and access roles
A durable ClearPass design begins by separating identity, context and enforcement. Authentication answers “can this user or device prove who it is?” Role mapping answers “what does the available identity and context tell us about this connection?” Enforcement answers “what access result should the network device apply?” Keeping those questions distinct makes policies easier to understand, test and modify. It also reduces the temptation to build one oversized service containing dozens of unrelated conditions.
For employee access, the policy might use directory group membership, certificate information or device-management context. Contractors may require a different identity source or an expiry-based role. Headless devices such as printers may depend on MAC authentication and profiling, which should be treated with appropriate caution because MAC addresses alone are not strong identity. Guests can use a separate access path so temporary visitor credentials do not become corporate identities. Each path should have a defined enforcement result and a clear denial or quarantine outcome.
FourTeck can help establish naming standards, service evaluation order and reusable role logic. This matters when the environment grows. Administrators should be able to understand why a request matched a service and why a role was assigned without reverse-engineering months of ad-hoc changes. Policy architecture also affects troubleshooting: well-structured services make Access Tracker results easier to interpret and reduce the time spent determining whether a failure came from identity, authentication method, authorisation data or enforcement.
RADIUS, 802.1X and TACACS+ integration needs careful end-to-end testing
RADIUS-based network access requires coordination between ClearPass, the network access device and the endpoint. A correct ClearPass service will not fix a switch port that is not configured for the desired authentication method, a wireless SSID that is pointing to the wrong RADIUS source, or a client that cannot trust the authentication server certificate. Similarly, attributes returned by ClearPass only have value if the receiving network infrastructure understands and applies them as intended.
For 802.1X, the authentication method and certificate strategy deserve special attention. EAP choices influence certificate requirements, client configuration and credential handling. Organisations using certificate-based access should confirm their certificate authority, enrolment process, certificate lifecycle and endpoint trust. Where password-based inner authentication is used, directory behaviour, credential policy and supplicant settings need to be considered. The configuration should be tested with representative Windows, macOS, mobile and specialist devices where those platforms are in scope rather than assuming one endpoint behaves like another.
TACACS+ is a different use case: it is commonly considered for administrative access to supported network devices, where authentication, authorisation and accounting can be centrally governed. Vendor-specific privilege levels, command sets and fallback procedures should be documented. Emergency local access must be handled according to the customer’s operational policy. FourTeck can assist with lab or staged tests so the organisation can verify successful login, rejected login, privilege assignment and accounting records before relying on the design for production administration.
Guest, onboarding, profiling and posture workflows must be scoped separately
ClearPass is broader than basic RADIUS, but not every capability is automatically included or required. ClearPass Guest can support controlled visitor-access workflows; ClearPass Onboard can support selected BYOD provisioning and certificate-oriented onboarding; ClearPass OnGuard can evaluate endpoint posture in supported designs; profiling can help classify devices using available network information. Each capability introduces its own prerequisites, licensing, user-experience decisions and operational responsibilities.
A guest project, for example, needs decisions about who can create accounts, whether sponsor approval is required, how long accounts remain valid, how visitors receive credentials, what terms are displayed, which network role is applied and how the captive portal certificate is trusted. A BYOD project needs decisions about who may onboard devices, how many devices are permitted, whether certificates are issued, what happens when employment or contractor status changes and how old registrations are revoked. Posture projects need specific compliance checks, remediation actions and support procedures for users who fail checks.
Profiling can improve context, but buyers should avoid treating device classification as unquestionable identity. The quality of profiling depends on the data sources available and the behaviour of endpoints. FourTeck can help separate high-confidence identity controls from supplementary context so the policy does not grant sensitive access merely because a device resembles a particular category. This separation is especially important for IoT and operational technology environments where many devices cannot participate in strong 802.1X authentication.
Where ClearPass configuration is commonly used
Corporate offices
Employee 802.1X, corporate and unmanaged device separation, guest access and administrator AAA can be brought under one policy framework where the infrastructure supports the design.
Education and campuses
Students, faculty, staff, guests, labs, printers and IoT devices often require different authentication and access outcomes. ClearPass can help organise these populations around explicit policy rules.
Hospitality and guest-heavy sites
Guest workflows can be separated from employee and infrastructure access, with captive portal and sponsor options determined by the required visitor experience and licence entitlement.
Healthcare and specialised device networks
Medical, facilities and IoT endpoints may not support the same authentication as user laptops. Policy design can combine stronger methods where possible with constrained treatment for exceptions.
Multi-site enterprises
Central policy can reduce inconsistent access decisions across branches, but redundancy, latency, RADIUS sourcing, site survivability and change sequencing must be considered in the architecture.
Network operations teams
TACACS+ workflows can help centralise administrative identity and accountability on supported switches, controllers and other network devices, subject to vendor-specific behaviour.
Operational considerations after the initial build
ClearPass configuration should be treated as an operational system, not a one-time installer task. Identity groups change, certificates expire, network devices are replaced, software releases introduce changes, guest workflows evolve and new endpoint categories appear. A design that works at go-live needs ownership so somebody knows who may modify services, how changes are reviewed, where backups are stored, which certificates are approaching expiry and how access incidents are investigated.
Monitoring should include service health, authentication failures, certificate issues, directory connectivity and unusual policy results. Access Tracker is valuable for request-level analysis, but troubleshooting also requires network-device logs, client information and an understanding of the chosen EAP or TACACS+ flow. Change records should explain why a policy was altered, not only what object changed. This is particularly important when multiple administrators work on the same ClearPass cluster.
High availability and clustering require their own design decisions. Publisher and subscriber roles, authentication traffic distribution, database replication, backup, certificate handling and network-device RADIUS-server ordering should be aligned to the required failure scenarios. FourTeck can discuss ongoing support or periodic configuration review as a separate scope after the original implementation, depending on the customer’s operating model.
Questions buyers should resolve before requesting a quotation
The effort is very different between a clean build, a policy redesign and troubleshooting an established production system.
Switches, controllers, access points, VPN gateways and administrative endpoints influence integration and testing work.
Directory services, local repositories, certificate authorities and external identity systems may each introduce connectivity and policy requirements.
802.1X, MAC authentication, guest access, TACACS+, VPN authentication, onboarding and posture should be specified separately.
Define roles, VLANs, downloadable attributes, ACL behaviour or other supported enforcement outcomes instead of stopping at “authentication succeeded.”
Unknown, unmanaged and failed endpoints need deliberate deny, restricted, remediation or guest treatment according to risk.
ClearPass configuration procurement checklist
- Confirm ClearPass software version and deployment type.
- Confirm appliance or virtual instance details and cluster topology.
- Provide the current licence or subscription entitlements.
- List the sites, switches, controllers and VPN systems in scope.
- Identify required RADIUS, TACACS+, guest and onboarding workflows.
- Document identity sources and relevant directory groups.
- Confirm certificate authority, server certificate and client certificate requirements.
- Define expected roles, VLANs, ACLs or other supported enforcement results.
- Identify endpoints that cannot use 802.1X and how they should be treated.
- Confirm whether network-device configuration changes are included in scope.
- Provide test accounts, representative endpoints and a change window.
- State whether documentation, handover, training or post-change support is required.
How FourTeck can assist with planning and configuration
FourTeck can support the project from requirement clarification through controlled implementation. The first step is to understand the operational outcome: for example, whether the customer wants certificate-based employee Wi-Fi, differentiated access by Active Directory group, guest sponsorship, network-administrator AAA or a broader NAC redesign. From there, the required ClearPass components and dependencies can be identified without assuming that every available module belongs in the project.
Depending on the agreed quotation, assistance can include policy workshops, configuration review, RADIUS and TACACS+ service design, authentication-source integration, network-device definitions, role mapping, enforcement logic, guest or onboarding configuration, test planning and documentation. Where switch, wireless or firewall changes are necessary, the quotation should state whether those changes are included or remain the customer’s responsibility. For wider infrastructure needs, buyers can also review FourTeck technology services and the networking and security product portfolio.
The final scope can also include a test matrix and knowledge transfer. A test matrix is useful because it documents expected results for different users, device types and connection methods. Knowledge transfer helps the customer’s IT team understand how services are matched, where to find authentication results and which dependencies should be checked before a policy is edited. To discuss these options, use the FourTeck contact page.
UAE availability and support guidance
HPE Aruba ClearPass configuration assistance in the UAE should be scheduled after the exact project scope is understood. Availability may depend on the ClearPass release, licence status, number of sites, required integrations, customer change windows and whether work is remote, on-site or a combination. FourTeck can help review the requirement, prepare a service scope and coordinate a quotation. Installation or configuration activity should not be assumed to include switch changes, certificate authority work, endpoint configuration or third-party system changes unless those items are specifically listed.
Customers can speed up the quotation process by sharing the current architecture, ClearPass version, affected sites, desired authentication methods, network-device inventory and any existing diagrams or policy documents. Contact FourTeck to confirm current UAE service availability and the expected scheduling approach after the technical requirement has been reviewed.
Dubai, Abu Dhabi, Sharjah and Ajman project coordination
Businesses in Dubai, Abu Dhabi, Sharjah and Ajman can discuss ClearPass requirement review, configuration planning and implementation coordination with FourTeck as one UAE project rather than treating each city as a separate technology design. Multi-site organisations should identify which locations host ClearPass nodes, directory services and central network services, and which sites only contain network access devices. That information helps determine RADIUS traffic paths, resilience requirements and appropriate testing. On-site activity, access permissions, travel, maintenance windows and local facility rules can affect scheduling, so these items should be confirmed in the quotation rather than assumed.
GCC Availability
FourTeck can assist organisations planning HPE Aruba ClearPass configuration across GCC environments, including projects that involve more than one office, data centre or operating country. The first step is to define the destination, current ClearPass platform, number of sites, licence status and required workflows. A UAE deployment may have different operational or scheduling needs from an environment in Saudi Arabia, Kuwait, Qatar, Bahrain or Oman, particularly when customer access rules, local change windows and network architecture differ. Requirement review, model or licence guidance, quotation coordination, configuration scope, installation planning and renewal discussion can be addressed as appropriate to the project. Product availability, software entitlement, service visits, vendor lead times and delivery schedules can vary by country, model, quantity and requirement. Buyers should therefore share the exact country, required ClearPass service, endpoint scale, licence term where relevant, deployment locations and expected timeline before a commercial commitment is made. For Kuwait-specific coordination, customers may also review FourTeck Kuwait resources.
Africa Availability
Organisations planning ClearPass projects in Africa can engage FourTeck for requirement clarification, policy design discussion, licence and platform review, configuration scoping, support planning and regional procurement coordination. The practical scope may vary substantially between a single office with a local ClearPass appliance and a distributed environment serving multiple branches. Buyers should provide the destination country, exact ClearPass deployment details, number of sites, endpoint population, authentication methods, expected project schedule and any requirement for on-site assistance. Availability and fulfilment can depend on destination, model, licence region, software entitlement, power or regulatory requirements, shipping arrangements, vendor lead time and local project conditions. Configuration work may also depend on remote access, change control and the availability of customer network teams. FourTeck does not assume local inventory or guaranteed deployment dates; these should be confirmed for the specific requirement. Businesses can review FourTeck Africa, Kenya technology support or Uganda technology support where relevant.
Related options to consider with a ClearPass project
Switch and wireless configuration
ClearPass policy only becomes effective when the access infrastructure sends the correct requests and applies returned enforcement. Include switch or WLAN changes in scope when the customer team will not handle them.
Certificate and 802.1X planning
Certificate-based authentication can strengthen identity but requires PKI, enrolment, trust and lifecycle planning. Treat endpoint certificate work as a separate deliverable when necessary.
ClearPass Guest
For visitor access, consider portal, sponsor, account-expiry and enforcement requirements. Feature availability and workflow options depend on licensing and the chosen ClearPass release.
ClearPass Onboard or OnGuard
BYOD onboarding or endpoint posture can be included where required, but these functions have additional client, certificate, licensing and operational dependencies.
NAC migration assessment
Replacing another RADIUS or NAC platform requires policy mapping, endpoint analysis, integration review, coexistence planning and staged cutover rather than a direct object-for-object copy.
Operational review
Existing deployments can benefit from a health and policy review focused on service order, certificate lifecycle, stale objects, cluster condition, logging and documentation quality.
What buyers are really trying to solve with ClearPass
Most organisations do not begin a ClearPass project because they want another authentication server. They begin because access has become difficult to govern. A wireless password may be shared too widely, contractor access may depend on manual exceptions, printers and IoT devices may be placed in the same VLAN as user computers, or network administrators may use local accounts that are difficult to audit. ClearPass becomes relevant when the organisation needs a policy decision point that can evaluate available identity and device context and return an appropriate access result to supported network infrastructure.
Do I need ClearPass for Wi-Fi only?
No. HPE positions ClearPass for role- and device-based access across multivendor wired, wireless and VPN environments. In practice, the useful scope depends on whether the surrounding switches, wireless platforms and VPN systems support the required RADIUS or enforcement functions. A buyer should identify all access paths before designing policies so wired and wireless users are not governed by unrelated rules without reason.
Can ClearPass work with Active Directory?
Active Directory is a common identity source in ClearPass designs. The important question is not simply whether it can be connected, but which attributes or groups will influence access, how domain connectivity and DNS are designed, and how failed or unavailable directory lookups should affect authentication. Buyers should list the exact groups and intended access outcomes before implementation.
What is the difference between RADIUS and TACACS+ here?
RADIUS is commonly used for network access authentication such as 802.1X and VPN workflows, while TACACS+ is commonly considered for administrative access to supported network infrastructure. They solve related but different problems. A project requiring both should document two policy models, two test plans and any vendor-specific privilege behaviour rather than treating TACACS+ as a checkbox inside an 802.1X deployment.
Is MAC authentication enough for IoT?
MAC authentication can be useful for devices that cannot perform 802.1X, but a MAC address is not a strong secret and can be copied. For that reason, the policy should normally combine device classification and restricted network access with other controls available in the environment. Buyers should inventory non-802.1X devices and define the minimum access each category genuinely needs.
Another common question is whether ClearPass automatically assigns VLANs. It can return suitable enforcement attributes, but the actual result depends on the access device and its configuration. Some environments use VLAN assignment, others use downloadable roles, ACLs or vendor-specific policy constructs. The right decision is the one the switches and wireless platform can enforce consistently. During discovery, the customer should provide examples of the desired access—for example, “finance-managed laptops require corporate application access, contractor laptops require internet plus one SaaS service, and printers require print-server connectivity only”—instead of asking for generic “secure VLANs.”
Buyers also search for the “best ClearPass configuration,” but there is no universal policy set. A design suitable for an office with managed Windows laptops can be inappropriate for a hospital containing medical equipment, or for a university with thousands of student-owned devices. Policy should reflect endpoint capability, identity assurance, business risk and the enforcement features of the network. This is why a configuration quotation should be based on use cases and integrations, not only endpoint count.
Pricing and implementation effort are similarly scope dependent. The public product ecosystem includes different ClearPass licences, endpoint counts, subscriptions and support options, while professional configuration effort depends on how many workflows need to be created or repaired. A buyer preparing a quotation request should therefore provide the number of ClearPass nodes, current version, sites, network-device vendors, estimated endpoint populations, identity sources, authentication methods and any guest, onboarding, posture or TACACS+ requirement. Screenshots or an exported configuration can help with an existing environment, subject to the customer’s security policy.
Troubleshooting searches often focus on “ClearPass authentication failed,” but that message alone is too broad. A failed connection can originate at the supplicant, certificate chain, EAP negotiation, RADIUS reachability, shared secret, service classification, identity source, role mapping, enforcement profile or network-device application stage. Good operations therefore start with the actual request in Access Tracker and correlate it with the endpoint and network-device logs. A configuration project should leave the customer with enough structure to follow that path rather than creating policies that only the original engineer can interpret.
Decision questions to answer before you change production access
Should we start with 802.1X or guest access first?
Start with the business use case that has clear ownership, test users and a controllable change window. Corporate 802.1X affects managed endpoints, certificate or credential policy and switch/WLAN configuration. Guest access affects captive portal, public certificates, account creation and visitor support. They can share ClearPass but they are separate implementation tracks. A phased deployment usually reduces the number of variables changed at once.
What information is needed to build role-based access?
Role-based design needs reliable attributes. These may come from directory groups, authentication method, device ownership, certificate fields, endpoint classification, location or other supported context. The business should define which attributes are trustworthy enough to influence access and what each role is allowed to reach. If an attribute can be easily spoofed, it should not be the only basis for sensitive access.
Can we migrate from Microsoft NPS or another RADIUS platform?
Yes, migration can be planned, but the goal should be policy equivalence or improvement rather than literal copying. Existing RADIUS policies, certificates, network clients, authentication methods, returned attributes and exception rules need to be catalogued. ClearPass services should then be designed to deliver the required outcome. Coexistence and staged cutover may be useful where the network permits it.
How do we avoid locking administrators out with TACACS+?
Administrative AAA should be tested on a limited device set first, with a documented fallback or emergency local-access process approved by the customer. Vendor-specific privilege mapping and command authorisation should be verified before broad deployment. Production changes need a rollback plan because the impact of a failed network-admin policy is very different from a failed guest login.
Do we need a ClearPass cluster?
That depends on required scale, resilience, site architecture and recovery objectives. A cluster adds redundancy options but also introduces design questions around publisher/subscriber roles, replication, traffic distribution, certificates, backups and upgrade planning. The existing or proposed topology should be reviewed before nodes are added simply for the sake of having more servers.
What should be in the handover document?
At minimum, document the in-scope services, authentication sources, role mappings, enforcement logic, network-device groups, key certificates, test results, dependencies, known exclusions and rollback considerations. Useful handover material also explains how to interpret a failed authentication and who owns endpoint, identity, network and ClearPass troubleshooting responsibilities.
Why businesses contact FourTeck for ClearPass assistance
The practical value is in requirement clarification and implementation structure. Businesses contact FourTeck when they need help deciding which authentication method fits a user group, how existing switches should interact with ClearPass, whether a requested guest or posture workflow is licensed, how to organise role mapping, what information is required for a quotation, or how to stage a migration without changing every access path at once.
FourTeck can also help identify where a problem belongs. A failed 802.1X connection may require ClearPass work, endpoint-supplicant work, certificate changes, Active Directory investigation or switch configuration. Distinguishing those areas early can prevent an inaccurately scoped service. For company background and broader technology capabilities, buyers may review about FourTeck before requesting a formal quotation.
Frequently asked questions
What is included in an HPE Aruba ClearPass configuration service?
The scope can include discovery, authentication sources, RADIUS or TACACS+ services, role mapping, enforcement policies, network-device definitions, guest or onboarding workflows, testing and documentation. The exact deliverables should be listed in the quotation because endpoint, switch, PKI and third-party changes may be separate.
Can ClearPass authenticate users against Microsoft Active Directory?
ClearPass supports Active Directory integration in suitable configurations. The project should confirm DNS, domain connectivity, required directory groups, authentication method and what directory attributes will be used for role decisions.
Can FourTeck configure 802.1X with ClearPass?
802.1X design and ClearPass RADIUS policy can be included in the scope. Successful deployment also depends on client supplicants, certificates or credentials, network-device configuration and the selected EAP method.
Does ClearPass support TACACS+ for network administrators?
ClearPass supports TACACS+ services. Actual privilege and command-authorisation behaviour depends on the network-device vendor and configuration, so the required admin roles and fallback process should be tested before production rollout.
Is ClearPass Guest included automatically?
Do not assume guest, onboarding or posture capabilities are automatically included. Licence entitlement, software release and project scope should be verified before the configuration is quoted.
Can an existing ClearPass deployment be reviewed instead of rebuilt?
Yes. An assessment can focus on service order, policy logic, identity sources, certificates, network devices, cluster condition, old objects, logging and documentation. Recommendations can then be prioritised by risk and operational value.
Can ClearPass be used in a multivendor network?
HPE positions ClearPass for multivendor wired, wireless and VPN environments. The specific RADIUS attributes, CoA behaviour, TACACS+ features and enforcement options still need to be checked for each network-device platform.
How long does a ClearPass configuration project take?
There is no responsible fixed duration without a scope. Timing depends on the number of sites and workflows, existing configuration quality, licences, identity integration, certificate readiness, network-device changes, testing and customer change windows.
What information should we send for a quotation?
Share the ClearPass version and topology, licence details, number of sites, network-device vendors, endpoint scale, identity sources, desired 802.1X/MAB/guest/TACACS+ workflows, and whether switch changes, documentation or support are required.
Is HPE Aruba ClearPass configuration available in Dubai?
FourTeck can coordinate ClearPass configuration requirements for Dubai and the UAE. Current service availability, scheduling and on-site requirements should be confirmed after the project scope and customer access conditions are reviewed.
Plan the ClearPass configuration around your actual access policy
Share your ClearPass version, sites, network devices, identity sources and required authentication workflows. FourTeck can review the requirement and prepare a configuration scope covering the services, integrations, testing and documentation that are genuinely needed.
