CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
AppSec teams running Burp Suite who want to accelerate reflected XSS discovery without manual regex writing should evaluate Rexsser. The plugin extracts keywords from HTTP responses and tests them automatically, cutting the time spent on pattern matching during active scanning; at 75 GitHub stars and free pricing, it's low friction to pilot alongside existing Burp workflows. This is not a replacement for a full DAST platform,it's a focused XSS hunter that works within your existing tool, so teams expecting broader vulnerability coverage or supply chain scanning should look elsewhere.
