Incident response

Customer or Employee Data May Be Exposed

Quick answer

Contain the affected access, preserve evidence, and involve the relevant provider and qualified legal or incident-response support before making notification decisions.

Who this is for: Businesses that suspect personal, payment, health, or confidential data was accessed or disclosed.

What to do

  1. 01Identify and contain the affected account, device, system, or provider.
  2. 02Preserve logs, messages, files, and a timeline without altering evidence unnecessarily.
  3. 03Determine what data and people may be affected with the system owner.
  4. 04Review contractual, regulatory, insurer, and notification obligations with qualified professionals.

What this does not cover

This is not a breach determination or legal advice. Notification duties and deadlines depend on jurisdiction, data, contracts, and facts.
