Cisco Secure Access Control System (ACS) 5.8 is the final version of the product and has reached its End-of-Life (EOL)
. Because it is no longer supported, official downloads from the Cisco website generally require a valid Cisco.com login and a service contract. How to Access the ISO Official Cisco Portal: If you have an active support contract, you can log in to Cisco Software Central and search for "Secure Access Control System". Evaluation Licenses:
While trial license keys were historically available without a contract, the actual software ISO typically was not. Successor Product: Cisco has replaced ACS with Cisco Identity Services Engine (ISE)
. Most users are encouraged to migrate to ISE, which offers enhanced AAA and security capabilities. Key Feature: Rule-Based Policy Model A standout feature of ACS 5.8 is its Rule-Based Policy Model
. This allows for highly granular control over network access by using dynamic conditions rather than static lists. ACS 5.8 Release - Cisco Community
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.
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.
Note: I can provide a concise installation checklist, migration checklist to Cisco ISE, or an example command list for ACS 5.8 administration if you want — tell me which one.
