Three Articles caught my attention before testing Posture with Debian 12 (code-name Bookworm) ...
1. the Release Notes for Cisco Secure Client, Release 5.1:
- Web Deployment for DEB (Debian) installation is not currently supported.
- Modules provided with DEB (Debian) installer is: VPN and DART.

2. the Cisco ISE Network Component Compatibility, Release 3.5:

3. the Configure Linux VPN Posture with ISE 3.3:
Components used:
- Ubuntu 22.04
- Cisco Secure Client 5.1.3.62
Questions:
- Does anyone know when we'll have a Posture Module for DEB ?
- Has anyone used DEB with Posture, even with the standard Cisco Secure Client Pre-Deployment Bundle (Linux x86-64) ?
Best regards.
