DOMPurify is a free dynamic application security testing tool. Halo Security Application Scanning is a commercial dynamic application security testing tool by Halo Security. Compare features, ratings, integrations, and community reviews side by side to find the best dynamic application security testing fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Halo Security Application Scanning
Startups and mid-market teams running lean AppSec programs should start here if you need DAST without the operational overhead. Halo Security Application Scanning detects OWASP Top 10 and SANS CWE Top 25 vulnerabilities in production-safe conditions, agentless, with scheduled scanning and real-time alerts that route to Slack or email; it covers the detection half of the NIST CSF 2.0 picture thoroughly but doesn't touch remediation workflows or threat intelligence integration. Skip this if you're already running a mature AppSec pipeline with tight CI/CD integration requirements or need SAST coverage alongside dynamic testing.
