Astra Security DAST Scanner is a commercial dynamic application security testing tool by Astra Security. Probely (Snyk API & Web) is a commercial dynamic application security testing tool by Probely. 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 building APIs or JavaScript-heavy web apps need Probely (Snyk API & Web) because it actually discovers what you're running before it scans it, eliminating the guesswork that kills DAST programs. The headless Chrome spider handles modern SPAs and the native API scanning accepts OpenAPI and Postman Collections directly from your existing tooling, cutting weeks off typical deployments. Skip this if your primary concern is SAST or supply chain risk; Probely owns the runtime security layer (NIST ID.RA and PR.PS) but doesn't pretend to be your code scanner.
