Email Breach Response Checklist
A practical 16-step guide to help you respond fast when a mailbox is compromised.
When an email account is breached, minutes matter.
A single compromised inbox can expose confidential data, interrupt operations, and damage client trust.
Knowing what to do, and in what order, can be the difference between a contained incident and a full-scale breach.
That’s why we’re sharing this 16-step Email Breach Response Checklist - the same process we use when responding to live incidents across our clients.
What’s included:
A step-by-step framework for containment, investigation, and recovery
Clear actions for IT and compliance teams
Tick-box tracking and owner fields for real-world use
Guidance on ICO and Action Fraud reporting
Printable and digital versions for easy distribution
