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 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, auto-fix pull requests, and contextual scanning across multiple repos. It is 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, Gecko helps developers fix security issues fast. What makes Gecko different is its compiler-accurate code indexing and semantic name binding—similar to a language server protocol—allowing it to parse dynamically typed languages and understand the real meaning of your code. It also supports natural language security rules and native integrations with GitHub, GitLab, Slack, Jira, and Linear. Compared to traditional SAST tools that rely on pattern matching and produce many false positives, Gecko targets business logic flaws and cross-service risks that actually lead to breaches. It's purpose-built for modern microservice architectures, where vulnerabilities often span multiple trust boundaries.
