Granting and denying network access has evolved beyond simple user name and password verifications. Today additional attributes related to users and their devices are used as decision criteria in determining authorized network access. Additionally network service provisioning can be based on data such as the type of device accessing the network including whether it is a corporate or personal device.

The Cisco^® Secure Network Server is a scalable solution that helps network administrators meet complex network access control demands by managing the many different operations that can place heavy loads on applications and servers including:

• Authorization and authentication requests
• Queries to identity stores such as Active Directory and LDAP databases
• Device profiling and posture checking
• Enforcement actions to remove devices from the network
• Reporting

The Cisco^® Secure Network Server is based on the Cisco UCS^® C220 Rack Server and is configured specifically to support the Cisco Identity Services Engine (ISE) security application. The Secure Network Server supports these applications in five versions. The Cisco Secure Network Server 3515 and 3615 are designed for small deployments. The Secure Network Server 3595 3655 and 3695 has several redundant components such as hard disks and power supplies making it suitable for larger deployments that require highly reliable system configurations. The Secure Network Server 3615 3655 and 3695 are recommended for new installations whereas the Secure Network Server 3515 and 3595 are recommended for existing installations.
