Why DryRun Security Wins
DryRun Security Contextual Security Analysis engine catches
vulnerabilities that pattern-based tools consistently miss.
Contextual Analysis vs Pattern Matching
DryRun Security analyzes how your code processes data, not just what patterns it contains. That's why it caught authorization issues, user enumeration, and insecure tokens that Semgrep missed entirely.
Real-Time Developer Feedback
Get clear, actionable feedback in seconds within your pull requests. No buried reports or scattered comments just one comprehensive summary explaining what's wrong and how to fix it.
Natural Language Code Policies
Write security rules in plain English, not specialized syntax. Define policies like "don't allow token generation without SecureRandom" without learning a domain-specific language or maintaining complex rule files.
No Rule Maintenance Required
While Semgrep requires teams to curate and maintain rule files, DryRun Security works out of the box with high accuracy. Extend coverage through natural language policies without writing code.
Comprehensive Coverage
Detect both classic vulnerabilities (SQLi, XSS, SSRF) and complex logic flaws (IDOR, BOLA, broken authorization) that traditionally require manual code review to find.
Fewer False Positives
Focus on real vulnerabilities without flooding teams with noise. When DryRun Security flags something, developers know it's genuinely worth investigating, building trust in the tool.
More Accurate
We’re the most accurate SAST you can get in a PR. Going beyond regex and pattern libraries, DryRun Security inspects data flow across files and services.
Lower Noise for Higher Confidence
The Contextual Security Analysis engine reasons about exploitability and impact, not just the presence of a pattern.
No Rules to Maintain
No more regex or brittle rule groups that take hours to create, validate, and keep up to date. You get AI-driven, custom policy checks in every PR.
