CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and SMB teams that need continuous API security visibility without hiring dedicated AppSec staff should start here with Aikido DAST Scanner. It handles REST, GraphQL, and authenticated flows in a single scan cycle, and the automated Swagger generation means you're mapping attack surface the day you deploy, not weeks later. Skip this if you need SAST or SCA baked in; Aikido is DAST-only, which keeps it fast but leaves code and dependency risk uncovered.
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.
