No account and no email required. The optional email copy is available below.

How to use it

A working starting point, with the limits stated.

A bounded starter pack for turning Microsoft Defender signals into consistent actions and evidence. It covers triage, containment, email response, identity compromise, detection tuning and monthly operational review.

  1. Copy the files into an organisation-owned repository.
  2. Replace placeholders and name accountable owners.
  3. Review permissions, thresholds and approval points.
  4. Test in a controlled window and retain the evidence.

Scope note

Response authority, licensing and portal capabilities must be confirmed before an incident.

Templates are operating aids. They are not certification, legal advice or a claim that a target environment is secure.
