Test Your Live App with DAST (Dynamic Application Security Testing)
DAST tests an application while it runs. It helps detect runtime vulnerabilities and misconfigurations that static analysis can miss.
What is DAST?
A security testing approach that sends safe test requests to the running application to identify vulnerabilities—often without needing source code access.
Why does it matter?
Some issues only appear at runtime: misconfigurations, auth logic gaps, and real request/response behaviors are best validated with DAST.
How DAST works with GuardionX
GuardionX scans your target URL in a controlled way, discovers endpoints, analyzes parameters, and tests for common weaknesses with safe payloads.
Rate limiting and safe scanning controls help reduce the risk of disruption. Findings are prioritized by impact and likelihood.
- Endpoint discovery and parameter analysis
- Tests for common issues like SQLi/XSS/SSRF
- Rate limiting and safe scanning mode
- Clear reporting and prioritization
When should you use DAST?
Run DAST regularly on staging and before releases to catch runtime issues.
- Regular staging scans
- Release regression checks
- After adding new endpoints
- After configuration changes
FAQ
Should I run DAST in production?
Staging is recommended. If needed in production, restrict scope and reduce scanning speed.
How can DAST find issues without code access?
It analyzes responses and behavior signals and validates findings with safe test payloads.
Do I still need SAST?
Yes. SAST tests code; DAST tests the running system. Together they provide better coverage.
