CISM Incident Management Practice Question
What is the primary purpose of having a pre-established forensic retainer agreement with an external forensics firm?
⚠ Common exam trap

Correct answer & explanation
✓
To reduce time to engage during an incident
The primary purpose of a pre-established forensic retainer agreement is to reduce the time to engage during an incident. By having a contract already in place, the organization can bypass procurement and legal review delays, enabling the forensics firm to begin work immediately when an incident occurs, which is critical for preserving volatile evidence and minimizing damage.
