Description

Class 5 AVR

Secure Elements Class 5 AVR (Automated Vulnerability Remediation) is a security product that monitors and enforces security policies on network assets. Class 5 AVR is now known as C5 EVM (Enterprise Vulnerability Management). The Class 5 AVR software includes both server and client components.

Class 5 AVR client

The Class 5 AVR client listens on 60000/udp and an additional tcp port. This client receives commands sent by the Class 5 AVR server.
