Contrast Application Detection and Response (ADR) vs DOMPurify: Side-by-Side Comparison (2026)

Contrast Application Detection and Response (ADR)

Security teams protecting APIs and microservices in production will get the most from Contrast Application Detection and Response because it detects and blocks exploits in real time at the code level, which means you stop attacks without waiting for patches. The tool's continuous vulnerability monitoring combined with inline blocking addresses the gap most organizations face between detection and response, covering NIST DE.CM through RS.MI. Skip this if you need broad infrastructure visibility beyond applications; Contrast is application-focused and won't replace your CNAPP or network detection layer.

DOMPurify

Frontend developers and security teams protecting user-facing applications from XSS will find DOMPurify essential because it strips malicious scripts from HTML without breaking legitimate functionality, something most sanitizers fail at consistently. With 16,746 GitHub stars and active maintenance across thousands of production deployments, the library has been battle-tested against real XSS vectors that OWASP regularly updates. Skip this if your threat model requires server-side output encoding as your primary defense; DOMPurify is client-side hygiene, not a replacement for secure coding practices upstream.
