Our free domain security scan checks your email defences, open ports, and blacklist status. No signup required to run a scan. Takes less than a minute.
Four categories of passive checks — all from public data, no intrusive scanning, no login needed.
We check whether your domain is configured to prevent email spoofing and phishing impersonation.
Checks whether your mail server enforces encrypted transit, stopping man-in-the-middle interception.
Surfaces publicly exposed services on your domain's IP that attackers could exploit.
Checks whether your domain or IP appears on spam or threat intelligence blacklists.
A misconfigured SPF record lets anyone send email pretending to be you. A missing DMARC policy means phishing emails from your domain reach your customers. An open port is an unlocked door. Most businesses don't know these gaps exist until after an incident.
"90% of cyberattacks start with email. Most are preventable with basic configuration."
Type in your company's domain — e.g. yourbusiness.co.uk
No intrusive scanning, no login needed — we read publicly available DNS and threat intelligence data.
Colour-coded results show exactly where you pass, where you're exposed, and what the risks mean.
The scan gives you the data. Our team turns it into a plain-English report with prioritised fixes. Book a free 30-minute call and we'll walk you through the results.
