What this checks
Understand the browser protections your site sends.
We check the public HTTP response and explain each result in plain language. Use the report as a conversation starter with your developer.
What do I receive?
A score, a concise finding for each header checked, recommendations and a downloadable PDF. Guests can return to recent reports in the same browser; verified accounts keep reports across devices for up to 12 months.
How many scans are free?
You can run up to two free scans without signing in. A secure browser cookie and a server-side network allowance stop a refresh, another browser or signing in on the same network from restarting that allowance. Accounts are also limited to two free scans in total. Shared networks may reach the limit sooner. An anonymous visitor using a different network cannot always be recognised as the same person. After the free allowance, one scan is £2.99, five are £13.45 (10% off) and ten are £23.92 (20% off).
Does this prove my site is secure?
No. This tool checks a focused set of public response headers at one point in time. It does not test application code, hosting configuration, authentication, access control or other attack paths.
