About Gecko Security

Gecko Security is a web-based AI security tool that reads a codebase's code, infrastructure and design documents as one system to find vulnerabilities. It focuses on issues such as business logic flaws, broken access control, injection, SSRF and multi-step attack chains that cross services and languages, and it ranks findings by the attack path they form rather than as a flat severity list. Each finding is reported with a source-to-sink call chain and a proof of concept.

Key features

  • Analyzes code, infrastructure and design docs as one system
  • Targets business logic flaws, access control, injection and SSRF
  • Prioritizes findings by attacker-relevant attack paths
  • Fixes the root design decision and every variant in one pull request
  • Adds guardrails on pull requests and for AI coding agents
  • Native connectors for Claude, Codex and any MCP server
Best for: Engineering and application security teams that want exploitable vulnerabilities found and fixed at the root rather than re-reported pull request by pull request.
Good for
  • Reports each finding with a full source-to-sink call chain and a working proof of concept
  • Fixes a vulnerability class at its root instead of individual tickets
  • Connects to repositories, pipelines and trackers, including AI coding agent workflows
Watch out for
  • Pricing is not published on the homepage; a free trial and demo booking are offered
  • Web platform only and closed source, so no self-hosted use is described
  • No information is given about geographic availability, data residency or handling of uploaded code

Gecko Security FAQ

What kinds of vulnerabilities does Gecko find?
The homepage says it targets business logic flaws, broken access control, injection, SSRF and multi-step chains that cross services and languages, with each finding including the full source-to-sink call chain and a working proof of concept.
How does fixing at the root work?
According to the homepage, Gecko traces a finding back to the design decision that created it, locates every variant across the repositories, and opens one fix covering the whole class, with guardrails so the pattern cannot be committed again.
Why does Gecko measure recurrence instead of MTTR?
The homepage argues that MTTR rewards closing tickets quickly even if the same flaw returns, while recurrence measures whether a flaw stayed fixed.
Is something wrong or out of date?
