Aruba ClearPass

Aruba ClearPass gives you complete control over who and what connects to your network. You can automatically identify every device—from smartphones and laptops to specialized IoT hardware—and apply precise security policies based on user roles or device types. This ensures that only authorized users access sensitive data while guest users remain safely isolated.

You can simplify your security operations by replacing manual configuration with automated workflows. The platform works across any vendor's networking hardware, allowing you to maintain consistent security standards without being locked into specific brands. Whether you are managing a single office or a global enterprise, you can monitor connection health and remediate non-compliant devices in real-time to prevent potential breaches.
