Security Tools

Free tools that check your own domain, inbox and website. No sign-up, no email address, no upsell.

The tools

  • Email Spoofing Check: See whether someone else could send email pretending to be your business: one grade, one fix, no jargon.

  • Website Exposure Check: A health check of your website's security headers, certificate and cookies.
  • Security Baseline Check: Check your domain's email and website setup against a published baseline. Pass, and you can show a dated badge that we re-check every week.
  • Email Header Analyzer: Paste a suspicious email's headers and get a straight verdict, including whether its unsubscribe link is safe. Nothing leaves your browser.
  • Breach-Notification Deadline Calculator: Work out your GDPR 72-hour notification deadline and what an initial notice needs to say.
