What are the two jobs of agentic AppSec?
Govern what agents build
Coding agents write code, install packages, run shell commands and call MCP servers. Governing them means knowing which agents, models and MCP servers are in use, and allowing, steering or blocking what they do, at the endpoint, in the IDE or at the pull request.
The aim is to show agents the right path, not just block the wrong one.
Let agents do AppSec work
The same platforms now ship agents of their own: triage agents that rank findings by reachability or business context, and remediation agents that write the fix. The useful questions are what each agent fixes, where the fix lands and whether the vendor says it is checked.
We score both halves. Three agent governance criteria carry 25% together and agentic remediation 20%; triage, SDLC policy, orchestration, named agent reach and pricing make up the rest. Scoring method
Where along the pipeline does each platform act?
- Documented
- Partial
- Not documented
A filled node means the vendor's own pages describe a control at that point. It does not measure how well the control works.
7 of 10 ranked platforms document a control on the coding agent itself; 6 of 10 document an agent or AI feature that writes the fix.

* Codex: supported, per Legit (confirmed to the publisher in October 2026).
- Legit Security's public pages name Claude Code, Cursor, GitHub Copilot and Windsurf. Codex: supported, per Legit (confirmed to the publisher in October 2026).
- Cycode names Cursor, Copilot, Windsurf and Tabnine on its AI page; its 17 February 2026 AI Guardrails post says Claude Code was supported at launch.
- Snyk names Claude on the Evo page and Claude Code on its homepage.
- Legit Security also names Amazon CodeWhisperer and MCP server based assistants.
- Aikido's entries refer to its IDE plugin, not to controls on the agent.
- GitHub's entry refers to the built-in checks on its own Copilot coding agent.
- Other agents named by vendors: Tabnine (Cycode), Antigravity (Endor Labs, Snyk), Qodo (Snyk), Gemini CLI (Apiiro MCP server).
- Wiz names Claude Code and Cursor for its Wiz Code plugins, and GitHub Copilot and Cursor as IDE extensions its AI-BOM inventories.
- Backslash's AWS listing names Cursor, Windsurf and GitHub Copilot. Its homepage product demo shows other agents, including Claude Code and Codex, as an illustration; we count only the listing.
Where does the top-ranked platform fall short?
- Agent policy enforcement and audit: Legit 8 / 10; highest Backslash Security 9 / 10
- Pricing and trial transparency: Legit 4 / 10; highest GitHub Advanced Security 9 / 10
We show these rows because a ranking where one vendor wins every criterion would not help a buyer.
What does this site measure, and what not?
We score how well each platform governs software built with AI coding agents and how much AppSec work its own agents take on, using public vendor pages, changelogs and standards documents read in September 2026 and updated on 11 October 2026. Every score has a written reason and a source. We did not run the products. Read the scoring method
Frequently asked questions
What is agentic AppSec?
Agentic AppSec is application security for a software process in which AI agents take part. It covers two things: controls on the coding agents that write and change code, and AI agents inside the AppSec platform that triage, prioritize and fix findings. The AppSec course explains both.
Which agentic AppSec platform ranks first?
On our published weights, Legit Security ranks first at 8.80 out of 10, followed by Cycode and Endor Labs. The agent risk calculator re-ranks the platforms on your own weights and the agents you run.
Do agentic AppSec platforms replace SAST and SCA?
No. Every platform here still scans code at commit and pull request. Agent controls reduce what goes wrong while the agent works, and fix agents act on findings that scanners produce.
