// About This Service

Clarity before You Have to Decide Anything

Not every alert is a breach, and not every breach is reportable. Our assessment service helps you work out what you are actually dealing with before you make decisions about notification, remediation or disclosure. We look at the evidence objectively and explain what it means in plain terms.

That matters because the ICO's 72 hour reporting window starts when you become aware of a qualifying breach, and both under-reporting and over-reporting carry real consequences.

  • A Clear Answer on Whether a Reportable Breach Has Occurred
  • An Understanding of Which Data and Systems Were Affected
  • Guidance on Your Obligations under UK GDPR and Related Law
  • A Documented Basis for Any Decisions You Need to Make
