Threat intelligence communities and industry groups surface risks earlier than you'd catch them alone.

What auditors expect to see
List of memberships/subscriptions and how information from them gets actioned.
Track A.5.6 in your own Statement of Applicability — mark it applicable, log your justification, and link it to the risk that drove it.
