Cisco Secure Access Control Server 5.7 Minor Upgrade | Windows, Security — CSACS-5.7SW-MR-K9=

Maintain continuity in your access control stack with Cisco Secure Access Control Server v. 5.7 minor release licensing. Built for customers already running ACS, this upgrade path keeps the environment aligned with the 5.7 release while preserving the investment in your existing server-based deployment. For teams responsible for authentication and policy enforcement, minor release licensing matters because it reduces disruption. You can stay on a supported software level without changing the operating model or introducing a new platform migration project. That makes this a practical choice for organizations that need to keep access services stable while meeting internal maintenance requirements. This license is tied to one server and supports Windows, matching the existing ACS deployment model in many enterprise environments. It is a focused procurement item: no excess capacity, no unnecessary bundle, just the entitlement required to move an installed ACS instance forward. For infrastructure teams, that precision helps control spend while protecting the access control layer that sits in front of critical systems.
