DAST Tools in 2026: Features, Strengths and Limitations
Summary
The guide compares DAST tools on authenticated testing, API coverage, finding verification and workflow integration. It explains DAST’s runtime strengths and limitations, including its difficulty detecting business-logic flaws, and offers selection criteria.
Key points
- DAST tests running applications by sending inputs through live interfaces, helping identify runtime issues such as injection, broken authentication and server misconfigurations.
- The guide compares tools on authenticated testing, API and GraphQL coverage, finding verification, CI/CD fit and intended use.
- Single-page apps, complex login flows, token-based authentication and APIs can challenge tools built for simpler web applications.
- Pattern-matching DAST may miss business-logic problems such as broken authorization, insecure direct object references and cross-tenant access.
- The guide recommends evaluating application coverage, how findings are verified, and whether results reach developers through pull requests or issue trackers.
- It describes OWASP ZAP as a free, open-source option and Burp Suite as a toolkit for manual and automated testing, while noting limitations for each.
- The article promotes Aikido’s pull-request integrations and AI pentesting capabilities; these are presented as product claims.
