How dynamic application security testing validates risk at runtime
Brief
Security teams already have long queues of potential application vulnerabilities. The useful question is what happens next: can they see how a weakness behaves in a running application, reproduce the attack, and give developers enough evidence to fix it? Dynamic application security testing (DAST) helps answer those questions by testing applications as an attacker encounters them.
The IDC MarketScape: Worldwide Dynamic Application Security Testing 2026 Vendor Assessment (Doc #US54119126, September 2026). The IDC MarketScape evaluated 16 vendors and named Rapid7 a Leader. We believe the result reflects the strength of Rapid7’s DAST capabilities, but the IDC MarketScape also offers a useful view of where the category is heading.
DAST has developed beyond traditional web scanning into a source of runtime evidence that can help organizations validate risk across the application layer.
