Security test questions

Straight answers about your grade.

Still unsure? Ask a WordPress expert

How does the security test work?

It runs your site through the Mozilla HTTP Observatory, which checks your security headers, cookies and redirects. The grade and score are the exact values Mozilla reports.

What do the grades mean?

Every site starts at 100. Mozilla takes points off for missing or weak protections and adds a few for extra ones. A means strong, B and C have gaps, and D or F means you’re exposed.

Does a good grade mean my site is safe?

Not on its own. Headers are one layer. Malware, weak passwords and old plugins can still put a site at risk, so pair this test with regular scans and updates.

Why didn’t my grade change after a fix?

Results are cached for an hour per site. Wait a bit, then run the test again. Some fixes also need a cache clear at your host or CDN.

Can you fix my headers for me?

Yes. Our Security Hardening service sets up headers and locks down the rest of your site. Every WP Farm hosting plan also includes Imunify360, KernelCare and a Cloudflare WAF.

Is the test really free?

Yes. No signup and no card. Run it whenever you change your site or hosting.
