The OWASP Top 10 represents the most critical security risks to web applications. MergeGuide ships detection rules mapped to all ten categories and enforces them at every layer of your development workflow, from IDE write time and AI generation time to git hook and PR gate.
The OWASP Top 10 is the most widely referenced security standard for web application development. It is referenced by PCI-DSS, HIPAA security guidance, SOC 2 auditors, and enterprise security procurement requirements. Demonstrating OWASP Top 10 coverage is increasingly a table-stakes requirement.
Many OWASP Top 10 vulnerabilities are detectable in source code before they become runtime exploits. MergeGuide's detection rules identify the code patterns that create these vulnerabilities, catching them at the point of authorship rather than after a penetration test.
MergeGuide's Free tier includes OWASP Top 10 detection: a baseline ruleset of Semgrep rules and regex patterns across the supported languages, with a signed evidence artifact generated for every evaluation. No paid tier is required to start with baseline coverage.
MergeGuide detection rules map to every OWASP Top 10 (2021) category with code-level detection patterns:
OWASP Top 10 detection is included in MergeGuide's Free tier: a baseline set of Semgrep rules plus regex patterns across the supported languages. Every individual developer gets baseline OWASP coverage with no subscription required.
SOC 2, PCI-DSS, and enterprise security questionnaires regularly ask for OWASP Top 10 coverage evidence. MergeGuide generates signed artifacts for every evaluation, giving your security team documentation that reports continuous OWASP enforcement across the codebase.
AI coding assistants can generate OWASP Top 10 vulnerabilities at scale. MergeGuide's MCP server injects OWASP policies into AI coding tools, working to keep these vulnerabilities from being introduced in the first place. Detection and prevention, not just detection.
Selected examples of what MergeGuide catches. These patterns run on every commit, across the languages your team writes in.
| OWASP Category | What MergeGuide Detects | Severity |
|---|---|---|
| A03: Injection | SQL injection: unparameterized queries with user-controlled input | Critical |
| A03: Injection | Command injection via shell execution with unsanitized arguments | Critical |
| A07: Auth Failures | Hardcoded credentials, API keys, and secrets in source code | Critical |
| A02: Cryptographic Failures | Sensitive data stored without encryption or using deprecated algorithms | Critical |
| A01: Broken Access Control | Missing authorization checks on protected routes and resources | High |
| A05: Security Misconfiguration | Debug mode enabled, missing security headers, default credentials | High |
| A10: SSRF | User-controlled URLs passed to HTTP client functions without validation | High |
