What happens if you ignore it

  • 1
    Customer data leak. A GDPR fine can reach 4% of revenue. Reputation damage lasts years.
  • 2
    Domain abused for spam. With weak SPF and DMARC, anyone can send email in your name.
  • 3
    Search penalty. Google pushes HTTP sites down and warns users away.
  • 4
    Site takeover. An outdated WordPress plugin can give an attacker admin access within minutes.

Why fix it now

  • A
    Fixes are cheap. Most headers take 15 minutes. An incident takes weeks.
  • B
    We're on your side. The scan and the report are free. If you're stuck, write to us and we'll help.
  • C
    EU + NIS2 ready. Built with NIS2 in mind. Our advice is written for small and mid-sized European businesses.
  • D
    Continuous watch. Watch checks your site every day and alerts you when something changes.

Find out where your weak spot is. It takes a few seconds.

The scan is passive and doesn't touch your site. No signup.
