Running a live incident
A breach has already happened. This is where you run it.
The clock, the record and the coverage in one place
Most of a breach is not the technical work. It is knowing when the clock started, keeping a record that will hold up months later, and answering the same questions from your board, your insurer and possibly the ICO — while the supplier who was breached tells you very little.
If it has only just happened, start with the playbook.
The data breach response playbook covers the first hour: containment, preserving evidence, the UK reporting decision and what to ask a breached supplier. Read that first, then open an incident to keep track of having done it.
