Acunetix Web Application & API Security vs Astra Website Scanner: Side-by-Side Comparison (2026)

Acunetix Web Application & API Security

Mid-market and enterprise teams scanning high-volume web applications and APIs will get the fastest time-to-remediation from Acunetix Web Application & API Security because its proof-of-exploit feature eliminates the false positive triage work that burns through security resources. The blended DAST/IAST approach detects over 12,000 vulnerability types including zero-days, and scheduled continuous scanning catches drift in multi-environment deployments. Skip this if your main gap is secure code review or SAST; Acunetix prioritizes detection over identifying vulnerable code lines early in the pipeline, so developers won't get line-level guidance before deployment.

Astra Website Scanner

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.
