Question 1

What does the WebAudit Versus tool compare?

Accepted Answer

Versus runs a simultaneous security scan on two URLs and displays the results in a side-by-side table. It compares HTTP security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy), TLS certificate validity and expiry, DNS email security records (SPF, DMARC, DKIM, CAA, DNSSEC), and the overall security score and grade for each site.

Question 2

Is the comparison tool free to use?

Accepted Answer

Yes, Versus is completely free and requires no account or login. Both URLs are scanned simultaneously using WebAudit's standard free scan, giving you header, TLS, and DNS results for each site. Full cookie and cross-origin isolation analysis in the comparison requires a Pro API key.

Question 3

What are good use cases for comparing two sites?

Accepted Answer

Common use cases include benchmarking your site against a competitor, comparing a staging environment against production before a deployment, auditing a client's site against a known-good reference, or demonstrating a security gap to a stakeholder by putting your site next to an industry leader like Cloudflare or GitHub.

Question 4

How is the Versus tool different from a regular WebAudit scan?

Accepted Answer

A regular scan at webaudit.in/scan.html analyses one URL and shows detailed results with fix recommendations for each finding. Versus scans two URLs in parallel and presents the results in a compact head-to-head table, making differences immediately visible at a glance. It is designed for comparison rather than remediation guidance.

Compare two sites side by side.
