Symantec Agent for Linux version

Note: The version (build number) reflects the version of the installer stub and typically matches the SEPM version but does not always match the agent version. This is because the installer stub is a script that downloads the latest version of the agent from the public repository, which may be more up to date than the SEPM version.

SEP Content Support Clarification

Summary: 

Content updates for SEP cease when the product version enters End-of-Service (EOS).

Details:

Broadcom is clarifying its policy on content update support for End-of-Service (EOS) Symantec Endpoint Protection versions.

Content updates contain information like virus definitions and behavioral rules. It is Broadcom’s policy that content update distribution is discontinued for versions of SEP that are EOS.

There are two main reasons for this policy:

  1. We want to incentivize customers to move to the latest version of our product. The latest versions have enhancements and vulnerability fixes that all customers need.
  2. Ensuring that new functionality delivered via content updates works in older, unsupported versions of the product takes significant testing which is unavailable.

Release Terminology

  • RTM - Release to Manufacturing
  • RU - Release Update
  • MP - Maintenance Patch
