An expired certificate puts a browser warning in front of your customers. Missing security headers are an easy fix that a lot of sites skip.
- Certificate expiry warnings 30, 14 and 3 days ahead
- TLS version
- HSTS, Content-Security-Policy, X-Content-Type-Options and Referrer-Policy
- Server version banners that give away more than they need to
Before we check your website, you prove you own the domain by adding a DNS TXT record, and you confirm in writing that we're authorised. Each check is one standard page request, the same as a visitor loading your homepage.
