CST VerdictShort answer
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. Startups and mid-market teams with limited AppSec headcount should use Intruder Web Application Scanning because the 24/7 automatic scanning and business-impact prioritization eliminate the manual triage work that makes DAST programs fail in small orgs. Seventy-five vulnerability types plus 140,000 infrastructure checks mean you're catching real issues without needing a dedicated researcher to interpret results. Skip this if your primary concern is API security at scale; the tool handles APIs competently through schema upload, but native API-first vendors will give you better coverage on GraphQL and async patterns.
