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:
Startup and mid-market teams shipping web apps and APIs fast will get the most from Astra Security DAST Scanner because it cuts noise without sacrificing coverage; 15,000 test cases mapped to OWASP Top 10, ASVS, NIST, and SANS, plus expert vetting of findings means fewer hours spent validating false positives. Native CI/CD hooks into GitHub Actions, GitLab, and Jenkins let you scan post-deployment without slowing release cycles, and authenticated scanning with TOTP and MFA support catches logic flaws agentless tools miss. Where it falls short: the NIST CSF 2.0 profile shows strong Risk Assessment but thinner Recover coverage, so this is detection-focused; teams needing integrated remediation tracking and incident response automation should look elsewhere.
Mid-market and enterprise teams securing Layer-1 protocols, smart contracts, or custom DeFi runtimes need FYEO Custom Fuzz Testing because it builds harnesses around your actual threat model instead of running generic fuzzing templates against your code. The stateful execution with shadow-state tracking and invariant checking catches logic flaws that stateless fuzzers miss, and CI integration means you're re-running those same reproducible seeds on every release. Skip this if your codebase is small or you're looking for a self-service tool; FYEO's 12-person team is built for hands-on engagement with mid-market and up, and that model doesn't scale to solo developers or teams that need instant turnaround.
