Introduction to “cisco-secure-client-macos-5.1.8.122-nvm-standalone.dmg” Software

This standalone DMG package provides the Network Visibility Module (NVM) component of Cisco Secure Client 5.1.8.122, designed for enterprise network traffic monitoring on macOS endpoints. As part of Cisco’s endpoint security analytics suite, this module enables IT administrators to analyze application usage patterns and user behavior through detailed flow records transmitted to Cisco Secure Network Analytics.

Compatible with macOS 13 (Ventura) through 15 (Sequoia), this March 2025 release focuses on enhancing threat detection capabilities for organizations using Cisco Secure Firewall 4200/3100 Series or Firepower Threat Defense 7.6+ platforms. The standalone format allows separate deployment from core VPN components, ideal for environments requiring granular network monitoring without full client installation.
