Xtension Overview

Xtension is the open plugin ecosystem for VAAST. It allows third-party and first-party tools to extend VAAST's functionality without modifying the core application.

Two types of Xtensions​

Official Sentrinels — first-party Xtensions built and maintained by Xtrinel LLC. These are closed-source, require a Pro or Enterprise plan, and appear in the "Official Sentrinels" section of the store. See The Sentrinel Network.

Community Xtensions — open source plugins submitted by the community via GitHub pull request. These can be free or pro-tier and must link to a public repository.

How Xtensions extend VAAST​

Xtensions can:

  • Add new tabs to the VAAST sidebar (e.g. a custom analysis view)
  • Add floating panels that overlay the main UI (e.g. a passive monitor)
  • Run passive analysis on proxy captures without any UI
  • Write findings to the scan results pane
  • Read proxy traffic, logs, and session metadata

All interaction happens through the VAAST Plugin API — a sandboxed interface that Xtension bundles call at runtime.
