Gecko Security
AI security engineer that finds and fixes exploitable 0-day vulnerabilities across your codebase.
Gecko is a strong pick for teams that need deep, low-false-positive vulnerability detection across microservices. Its AI-native semantic analysis and natural language rules set it apart from SAST tools like Semgrep or Snyk, which mainly handle simpler linting or container scanning. The free tier lets you test before committing; if you need on-prem or SSO, the Enterprise tier covers that.

Skip Gecko if you need a fast, lightweight linter, have no CI/CD pipeline, or cannot invest time in understanding deep findings; simpler tools like Semgrep or Snyk may suit you better.
The Pro tier is $100 per month for 100 scans; going over that means paying for more scans or upgrading to Enterprise, which is custom-priced and requires annual billing.

About Gecko Security
Gecko Security is an AI-native security engineer that goes beyond pattern matching to find complex, exploitable vulnerabilities in your codebase. It builds a compiler-accurate semantic graph of your application—understanding logic, data flow, and trust boundaries across microservices—to map full attack paths that traditional AST or SAST tools miss. This allows it to discover business logic flaws, multi-step attack chains, and even 0-day vulnerabilities that previously only humans could find. Gecko integrates into your CI/CD pipeline, providing PR scanning with AI SAST reviews, auto-fix pull requests, and contextual scanning across multiple repos. It's designed for engineering teams at both startups and Fortune 500 companies who want to ship secure code without slowing down, with an average time to remediation of 1 hour and 8x more true positives with 90% less false positives.
Behind the Verdict
Gecko stands out by targeting business logic flaws and multi-step attack chains that typical AST or SAST tools miss. It builds a compiler-accurate semantic graph of your codebase, using semantic name bindings similar to a language server protocol, which results in a false positive rate of around 20 per cent based on customer testimonials and industry benchmarks. This is significantly lower than many SAST tools, which often drown teams in false positives. The integration with CI/CD via a PR/MR bot and one-click autofix PRs helps developers resolve issues quickly, with an average time to remediation of 1 hour. Natural language rules let you express security policies like 'check bigco/webapp doesn't write data to a third-party API' and have Gecko apply them across your code, dependencies, and connected environment. Recent updates include a remote MCP server for AI tools like Claude, ChatGPT, Codex, and Cursor, with role-capped scopes and OAuth, plus a redesigned v1 API with cursor pagination and HMAC webhooks. These features make Gecko adaptable to modern AI-driven workflows. However, Gecko is not a lightweight linter; deep scans can take minutes, so it's best suited for teams with a CI/CD pipeline and the ability to invest in understanding findings. Solo developers or teams without a pipeline may find it overkill. The free tier is limited to 10 scans, and the Pro tier at $100 per month offers 100 scans and team management for up to 5 members. The Enterprise tier, with unlimited scanning, on-prem deployment, and SSO, is custom-priced with annual billing. For most security-conscious engineering teams, Gecko is a valuable addition, complementing but not replacing broader security tools like Snyk for container scanning or Semgrep for faster linting.

Featured Head-to-Head Comparisons
Gecko Security vs Sublime Security
Gecko Security and Sublime Security serve entirely different domains: code vulnerability detection vs. email threat defense. Gecko excels for engineering teams wanting deep, low-false-positive code analysis integrated into CI/CD, while Sublime is ideal for SOC teams needing advanced email security with custom detection rules. Choose based on your primary attack surface—code or email—since they are not direct competitors.
Gecko Security vs Audioeye
Choose Gecko Security if your priority is finding and fixing deep, 0-day vulnerabilities in your codebase with AI-powered semantic analysis; go with AudioEye if you need automated web accessibility compliance, including scans, overlays, and legal documentation. They solve different problems, so pick based on your compliance or security needs.
Gecko Security vs Push Security
Choose Push Security if your primary threat is browser-based attacks (AiTM, session hijacking) and AI tool data leakage; it provides real-time visibility and automated hunting across all browsers. Choose Gecko Security if your priority is finding and fixing complex code vulnerabilities (business logic, 0-days) in CI/CD with auto-fix PRs. They address entirely different layers of the security stack.
