Cisco Anyconnect Secure Mobility Client 4.10.06...

This client isn't just a dumb tunnel. Here are the standout capabilities present in build 06062.

Migration path: You can push a software upgrade from ASA to AnyConnect 4.x clients to move to 5.x, but not across major branches (4.x to 5.x) without a headend update first. Cisco recommends a staged rollout.

Given that Cisco released version 5.1.6+ and now 5.2.x, you might ask: Why stay on 4.10.06062?

Cisco AnyConnect Secure Mobility Client 4.10.06: Features, End-of-Life, and Migration

Cisco AnyConnect Secure Mobility Client 4.10.06 is a major maintenance release within the legacy 4.x software branch. Released primarily to address stability and security vulnerabilities, version 4.10.06079 (and subsequent sub-versions) serves as a critical bridge for organizations still operating on older infrastructure before transitioning to the modern Cisco Secure Client 5.0. Key Features and Enhancements in Release 4.10.06

This version introduced several refinements to the AnyConnect ecosystem, focusing on security integration and improved user identity management:

SAML External Browser Support: One of the most significant additions is the ability to use an external browser for SAML authentication instead of the embedded AnyConnect browser. This allows for advanced web authentication methods like biometrics (FaceID/TouchID) and WebAuthN.

Improved Captive Portal Detection: Enhanced logic for detecting captive portals (common in hotels and airports) when using the Secure Web Gateway (SWG) module.

User Identity Management: On Windows, the client transitioned to using UserPrincipalName rather than Active Directory GUIDs to retrieve user identities from the OS, improving compatibility in hybrid-cloud environments.

Next-Gen DNS Proxy: The Windows version moved to the dnscrypt-proxy v2 engine for more robust DNS security handling.

Apple iOS Updates: Maintenance fixes specifically addressed SAML external browser use for mobile devices and resolved bugs related to M1 Mac compatibility. Important Support Dates (EOL)

Users should be aware that the 4.x branch is currently in its sunset phase. Cisco has officially announced the following timeline: End of Software Maintenance March 31, 2024 Final Patch Release

No further maintenance releases or security patches will be provided for 4.x after this date. End of Application Support March 31, 2027

After March 31, 2027, all support services for AnyConnect 4.x will be discontinued, and the product will be considered obsolete. The Rebranding: AnyConnect vs. Cisco Secure Client

Cisco has rebranded AnyConnect as Cisco Secure Client. The jump from version 4.x to version 5.x marks this transition. While the core VPN functionality remains largely the same, the new branding unifies multiple security agents—such as AnyConnect, Secure Endpoint (formerly AMP), and Umbrella—into a single interface. Key differences in version 5.x:

Unified Agent: Integrates VPN, endpoint protection (EDR), and DNS security into one modular package. Cisco AnyConnect Secure Mobility Client 4.10.06...

Cloud Management: Includes a new cloud-based management system within Cisco XDR (formerly SecureX) for easier deployment and visibility.

Zero Trust Access: Introduces a dedicated Zero Trust Access module for more granular network control. Migration and Licensing For organizations currently using AnyConnect 4.10.06:

Eligibility: Customers with active AnyConnect / Secure Client term licenses or perpetual licenses with active support contracts can upgrade to Cisco Secure Client 5.x at no additional charge.

Auto-Update: If configured at the headend (ASA or FTD), 4.x clients connecting to a gateway running 5.x can be set to automatically upgrade to the new client version.

Support for Legacy OS: Note that while 4.10 supported older systems like Windows 8.1, the initial releases of Secure Client 5.0 are optimized for Windows 10/11 and recent macOS versions.

The Cisco AnyConnect Secure Mobility Client 4.10.06079 (also known as Maintenance Release 6) is a vital update in Cisco’s legacy AnyConnect 4.10 maintenance path. This release focused on enhancing cloud security integration through the Umbrella Roaming Security Module and improving connection stability across modern operating systems like Windows 11 and macOS. Key Features and Enhancements

This version introduced several targeted improvements to ensure a more seamless user experience and tighter security posture:

Improved Captive Portal Detection: Enhanced reliability when detecting captive portals (like those in hotels or airports) specifically when using the Secure Web Gateway (SWG).

Next-Generation DNS Proxy: Transitioned to dnscrypt-proxy v2 on Windows, providing a more robust engine for DNS-layer security. Identity Enhancements:

Windows: The client now uses UserPrincipalName (UPN) instead of the Active Directory GUID to retrieve user identity from the OS.

macOS: Added support for MDM-deployed user identities and faster client protection activation upon service startup.

SWG Connectivity: Allows user identity to be sent to the SWG even when DNS is disabled behind a virtual appliance. Bug Fixes in 4.10.06079

Version 4.10.06079 addressed several stability issues that plagued previous 4.10 builds:

Crash Fixes: Resolved a rare issue where the Umbrella module would crash after a web-deploy or cloud update on Windows. This client isn't just a dumb tunnel

Connectivity Stability: Fixed an issue where large DNS records (more than 4 CNAMEs) caused DNS response failures.

Performance Improvements: On macOS, improved behavior for server reachability tests and fixed intermittent website loading issues with SWG.

Interoperability: Fixed a known compatibility conflict with the Pulse Secure and Twingate clients. System Requirements and Compatibility

This release supports a broad range of modern and legacy environments:

Windows: Fully compatible with Windows 11, 10, 8.1, and 7. Note that it supports both x86 (32-bit) and x64 (64-bit) architectures.

macOS: Compatible with macOS 11 (Big Sur), 10.15, and 10.14.

Linux: Supports Red Hat (7 & 8) and Ubuntu (16.04, 18.04, 20.04).

Headends: Works with Cisco Secure Firewall ASA running software 8.0(4) or later. Installation and Deployment

For most enterprise environments, Cisco AnyConnect 4.10.06079 can be deployed using one of two primary methods:

Pre-deployment: Administrators can download the .msi (Windows) or .pkg (macOS) installers from the Cisco Software Central and push them via MDM or SCCM.

Web-deployment: When users attempt to connect to the VPN gateway (ASA or FTD) via a browser, the headend automatically pushes the latest client version to the endpoint.

Note on Branding: While the 4.10 series maintains the "AnyConnect" name, Cisco has since transitioned its security client to the Cisco Secure Client (version 5.x), which consolidates AnyConnect with other security modules like Secure Endpoint and ThousandEyes.
