Semgrep + StackHawk: Unified SAST & DAST For Faster Fixes

SAST and DAST each bring critical strengths to application security. Static analysis catches vulnerabilities early in the code, while dynamic testing validates what’s actually exploitable in running applications. Both are essential, but when they operate independently, they create an unexpected challenge: the same vulnerabilities are flagged multiple times.

A SQL injection flagged by SAST appears again in DAST results. An authentication bypass shows up as both a code-level finding and a runtime vulnerability.

Security teams spend valuable time manually correlating duplicates, trying to piece together which alerts represent the same underlying issue and which findings are actually exploitable in production environments. This disconnect between static and dynamic testing doesn’t just create duplicate work—it makes prioritization harder. When you can’t easily see the relationship between a code-level finding and its runtime behavior, it’s difficult to know where to focus remediation efforts first.

StackHawk’s integration with Semgrep solves this correlation challenge.

By automatically linking SAST findings from Semgrep with runtime API testing from StackHawk, security teams can now see a complete picture of their vulnerabilities, combining code-level detection with runtime validation to show exactly what’s exploitable in production.

Semgrep & StackHawk: Unified SAST + DAST Correlation

When talking with our joint customers, one theme kept coming up: both SAST and DAST provide valuable insights, but teams need help connecting them. At StackHawk, we’ve built our shift-left DAST to validate what’s actually discoverable and exploitable in running applications. Semgrep provides comprehensive code-level security scanning with customizable rules. Together, they’re more powerful than either alone.

The Semgrep & StackHawk integration delivers unified visibility across the security lifecycle. By connecting Semgrep’s best-in-class SAST with StackHawk’s developer-integrated DAST, teams can:

• Correlate findings between code and runtime to eliminate duplicate alerts
• Prioritize findings, combining code-level detection with runtime validation
• Leverage the strengths of both tools—catch issues early in code while catching discoverable and exploitable risks in runtime.

How the Integration Works

Our integration with Semgrep brings your code-level security findings into the StackHawk platform.

How it works:

1. Semgrep scans your codebase, identifying security vulnerabilities using its powerful, customizable rules
2. StackHawk tests your running applications directly in CI/CD pipelines, validating which code-level issues are actually discoverable and exploitable
3. When a matching finding is detected, StackHawk automatically correlates it to Semgrep’s code-level detections 
4. Security teams get a unified view from code to runtime

Comprehensive Coverage Requires Connected Tools

The strongest AppSec programs leverage multiple testing approaches—each tool provides a different lens on security risk. SAST excels at finding vulnerabilities early, before code ships. DAST validates what’s actually exploitable in real application environments. The challenge has always been connecting these insights.

As development accelerates—especially with AI-generated code creating new attack surfaces faster than teams can track—security tooling needs to work together seamlessly. Teams need automated correlation, validation, and prioritization built into their workflows, not more manual work connecting the dots.

The Semgrep + StackHawk integration represents this evolution: complementary security tools working in concert, not in silos. This is security built for the pace of modern development—comprehensive coverage from both static and dynamic testing, with automatic correlation that helps teams answer the question that matters most: “What should I actually fix first?”
