What we check
Four things that quietly matter
Secure connection
Whether your site loads over HTTPS and sends insecure visitors to the secure version.
Security headers
The behind-the-scenes settings that stop scripts, clickjacking and content-sniffing attacks.
Email anti-spoofing
Whether SPF and DMARC stop criminals sending invoices that look like they came from you.
Information leaks
Whether your site quietly advertises the software and versions it runs on.
Questions
Good to know
- Is this safe to run on my site?
- Yes. The check only reads settings your website already shows to every visitor's browser, plus public DNS records. It never tries to log in, guess passwords, or change anything.
- Should I only check my own site?
- Yes. Please only run the check on a domain you own or are authorised to check. That is what the confirmation box is for.
- What do the grades mean?
- Each area gets a traffic-light rating and a grade from A to F. Green is good, amber could be better, and red needs attention. Every red or amber item comes with a plain-English fix.
- Can you fix the problems it finds?
- Yes. I fix all of these as part of a new build or a one-off security hardening pass. Run the check, then click through to see what sorting your specific issues would cost.
