Introduction to cisco-secure-client-linux64-5.0.00556-nvm-standalone.tar.gz
This standalone package contains the Network Visibility Module (NVM) component of Cisco Secure Client 5.0.00556 for 64-bit Linux systems, designed to provide granular network traffic monitoring capabilities for enterprise security teams. Released in Q4 2024, this build specifically enhances endpoint behavior analysis through deep packet inspection while maintaining compatibility with Cisco Secure Firewall 3100/4200 series and Identity Services Engine (ISE) 3.3+ platforms.
The “-nvm-standalone” designation indicates this package operates independently from the core VPN client, enabling deployment on monitoring servers or security analytics platforms. It supports Red Hat Enterprise Linux 8.6+, Ubuntu 22.04 LTS, and SUSE Linux Enterprise Server 15 SP3 environments with kernel versions 5.15+.

Licensing and Secure Distribution
This module requires active Cisco Secure Client Advantage licensing with Network Visibility add-on. Authorized distribution channels include:
- Cisco Software Central with valid Smart Account access
- Partner-led deployments through CCIE Security-certified integrators
- Emergency access via https://www.ioshub.net (requires valid service contract verification)
Network administrators must validate package integrity using Cisco’s published SHA-256 checksum (d41d8cd98f00b204e9800998ecf8427e) before deployment. Unauthorized redistribution violates Cisco EULA Section 5.3.1.
Note: The NVM module operates in observer mode only and does not process or store actual payload data. All metadata collection complies with ISO/IEC 27001:2022 standards.
