Cisco AnyConnect 4.10.05 (specifically version 4.10.05085 ) is a legacy maintenance release of the Secure Mobility Client. While highly stable, it has officially reached its end-of-maintenance date as of March 31, 2024.
The following blog-style overview covers the key features, security fixes, and the critical migration path to its successor, Cisco Secure Client 5 🚀 Cisco AnyConnect 4.10.05: The "Reliable Workhorse"
For many IT departments, 4.10.05 became the gold standard for stability during the transition to hybrid work. It focused on refining the core VPN experience rather than adding flashy new tools. 🛠️ Key Features & Fixes Maintenance Focus:
This release was designed to fix bugs across the 4.x path, making it the most stable "end-of-life" version for those not yet ready for version 5. Improved Connection Stability:

Cisco AnyConnect Secure Mobility Client version 4.10.05 (specifically version 4.10.05095) represents one of the final stable maintenance releases in the 4.x family before the software's rebranding to Cisco Secure Client 5.x. Summary of Review
Version 4.10.05 is a "rock-solid" enterprise VPN solution known for connection stability and deep integration with Cisco's security ecosystem. However, users should be aware that the Cisco AnyConnect 4.x line reached End-of-Life (EoL) on March 31, 2024. Cisco now recommends migrating to Cisco Secure Client 5.1.x to receive ongoing security updates and bug fixes. Key Strengths
Cisco stopped publishing security advisories for the 4.10 train on October 31, 2024. Since that date, any vulnerability discovered (such as the critical CVE-2025-20124 privilege escalation flaw patched in later 5.x versions) remains unpatched in 4.10.05.
Using this client means your remote access VPN is vulnerable to known exploits that attackers are actively scanning for.
Pros:
Cons:
If you are upgrading from 4.9.x or earlier, version 4.10.05 introduces several changes that affect both end-users and network administrators.
It is impossible to discuss AnyConnect 4.10.05 without mentioning the transition occurring at Cisco. Cisco is actively rebranding and migrating the AnyConnect ecosystem into Cisco Secure Client.
Version 4.10 represents the matured peak of the "legacy" branding. While 4.10.05 is a robust and stable release suitable for immediate production environments, administrators should be aware that future innovations (and deeper integrations with Duo Security and CrowdStrike) will fall under the new "Secure Client" naming convention. However, 4.10.05 remains a highly recommended "safe harbor" release for organizations not yet ready to migrate to the newer branding infrastructure.
