We scanned

2,500 sites. Here's what we found.

91%

Have no working DMARC

Anyone can send email pretending to be them, and their own invoices land in spam.

93%

Fail Google's load-speed check

Slower rankings, higher bounce, fewer leads from the same traffic.

Over half

Run outdated software with known security holes

One scan away from being defaced or quietly compromised.

7 of 2,500

Sites scored above 90

Almost no owner actually knows where their site stands. Most assume it's fine.

Not another AI tool

Every scan runs eight engines against your site.

We run the actual tests a security engineer runs by hand, not a language model reading your page and guessing. Here is the difference.

Typical “AI” website checkers
  • Read the HTML your homepage returns
  • Ask a language model to find problems
  • Return plausible-sounding guesses
  • Give a different answer every run
AcuityScan
  • Opens real TCP and TLS connections to your server
  • Runs a real headless browser, not a text model
  • Queries live blacklists and DNS resolvers in real time
  • 350+ deterministic checks, the same result every run

Live handshake and cipher-suite analysis on your certificate, with expiry and chain validation.

Email authentication

DNS health

Accessibility

A full WCAG 2.1 AA audit in a real browser, at both desktop and mobile viewports.
