Cisco announced the End of Sale for ACS 5.8 in August 2017. Because the product is no longer actively maintained, you may find that documentation and downloads are eventually removed from the public site. If you have an active support contract but cannot find the file, you should contact Cisco TAC for assistance.
Cisco Secure Access Control System (ACS) 5.8 is officially End-of-Life (EoL) and End-of-Support, having reached its final support milestone on October 31, 2019. Because the product is retired, Cisco purposely removes these older software downloads and ISO images from its public website. Official Download Channels
While the ISO is no longer available to the general public, it can still be accessed by users with specific credentials:
Cisco Software Central: If you have an active service contract (CCO account) with entitlement for ACS, you may still find the ISO (typically named ACS_v5.8.0.32.iso) on the Cisco Software Download portal.
Support & Community: Users without a contract may find legacy peer support or documentation on the Cisco Community platform, though official software links will likely redirect to Cisco Identity Services Engine (ISE), which is the designated successor. Deployment Requirements
If you have obtained the ISO for lab or legacy purposes, the following minimum virtual machine requirements must be met for a successful installation: CPU: 2 vCPUs. Memory: 4 GB RAM.
Storage: 60 GB minimum for evaluation/trial versions; 512 GB for full production versions. If you need help writing a full article,
OS Environment: Typically deployed as a VMware virtual machine using CentOS 7 64-bit as the base OS profile. Successor: Cisco ISE
Cisco recommends migrating all remaining ACS 5.8 deployments to Cisco Identity Services Engine (ISE). ISE provides the same AAA (Authentication, Authorization, and Accounting) protocols—TACACS+ and RADIUS—but offers more advanced features for modern identity management.
