Gecko Security

What is Gecko Security?

Gecko Security is an AI code security tool for finding vulnerabilities that attackers could actually exploit, with a focus on business logic flaws, broken access control and multi-step attack chains. You connect a GitHub or GitLab repository, and a deep scan maps the code and investigates attack paths, keeping only findings it is confident are real, each with a source-to-sink call chain and a proof of concept. Lighter pull request checks then re-scan every commit and label findings as new, persisting or fixed. Results are ranked by the attack path they form rather than as a flat severity list. Gecko can open a fix pull request in the style of your codebase, send tickets to Jira, Linear, ClickUp or Shortcut, or hand findings to Claude, Codex, ChatGPT and Cursor over MCP, then rescans to confirm the fix. Pricing starts with a free trial of 10 scans, then Pro at $100 per month, with custom annual pricing for Enterprise.

Use cases

• Scan a repository for exploitable vulnerabilities
• Check every pull request for new security flaws
• Auto-generate fix pull requests
• Route findings to Jira or Linear tickets
• Feed findings to AI coding agents over MCP
• Export vulnerabilities to DefectDojo or GitLab

Who it's for

• Application security teams
• Software developers
• Engineering leaders
• CISOs

Why use Gecko Security

• Findings come with a call chain and proof of concept, so developers spend less time debating whether a report is real.
• Ranking by attack path puts chained low-severity bugs ahead of a critical issue nobody can reach.
• A single pull request can fix the design decision behind a flaw and its variants.
• Fixes are re-checked by a rescan after a merge or a closed ticket, so closure is verified.
• The trial runs on your own repository, a public repository or a ZIP upload before you pay.

How to get started with Gecko Security

1. Connect a GitHub or GitLab repository, or upload a ZIP or a public URL, and start a deep scan.
2. Gecko maps the repository, investigates attack paths and keeps the findings it is highly confident are real.
3. Review ranked findings with call chains and proof-of-concept details in the dashboard.
4. Send each finding as a ticket, an auto-fix pull request, or to an AI agent over MCP.
5. Pull request checks re-scan on each commit and a rescan confirms when a fix has landed.
