Gecko Security - 2026 Pricing, Features, Reviews & Alternatives

Gecko Security is an AI-native application security scanner that constructs a compiler-accurate semantic code graph across multiple repositories, microservices, and connected infrastructure to detect vulnerabilities that pattern-matching SAST tools cannot find. Rather than relying on signature-based detection, it traces untrusted input from entry point to impact, surfacing only proven, exploitable paths. Each finding includes full source-to-sink call chains, CVSS severity scores, proof-of-concept exploits, and ready-to-apply patches. Deployment options span cloud SaaS and self-hosted configurations, with support for private AI models to keep source code and vulnerability data under customer control.

Gecko Security targets security-conscious enterprises operating microservice architectures, multi-repo codebases, and cloud-native environments, including organizations shipping AI-generated code at scale. The platform detects multi-step and business logic vulnerabilities, including broken access control, IDOR, and privilege escalation chains, by scanning across service trust boundaries that isolated code scanners miss. Custom security policies can be authored and applied across code, dependencies, and connected environments, while HTTP attack surface discovery and architecture and routing mapping provide broad visibility into an application's security posture.

Developer and security teams interact with Gecko Security directly within existing workflows through native CI/CD pipeline integration and pull request reviews with one-click fixes. This allows vulnerabilities to be identified and remediated without context switching. The platform has contributed to the discovery of 30-plus open-source CVEs, surfacing findings that previously required manual penetration testing.
