Startup and SMB security teams with limited scanning budgets should start with Astra Website Scanner; the free tier covers malware and SEO spam detection while the paid plans unlock authenticated scanning and API testing without enterprise pricing. The 9,300+ vulnerability test cases and CI/CD integrations mean you can catch real issues before deployment, and continuous automated rescans verify that fixes actually stick. Skip this if you need SAST or infrastructure scanning; Astra is application-surface focused and won't tell you what's wrong with your cloud configuration.
Teams running distributed web applications and APIs who need to validate fixes without waiting for manual retesting will get the most from Cobalt DAST; its remediation validation workflow cuts the cycle between developer handoff and security sign-off. The platform integrates authenticated scanning across subdomains with false positive filtering via fingerprinting, reducing alert fatigue that kills DAST adoption. Skip this if your organization needs coverage beyond web applications or relies on a vendor pentest program as your primary validation layer; Cobalt DAST is automated scanning, not a replacement for human testers.
