Key takeaway
Base the choice on comparable evidence from the device inventory, pilot observations and operating requirements.
Define the environment and risk boundaries
Start selection with supported workloads and business requirements. Record the device inventory, operating-system versions, user roles and change constraints. Define the device and event information needed across distributed and cloud environments.
Unknown and fileless threats
Complement signature checks with behavioural analysis and account for script-based attacks and activity in memory. Ask the vendor how policy handles an unclassified executable and which resources isolation protects. When evaluating Zero Trust, clarify permission and isolation boundaries.
Coverage, management and analysis
Verify central management, integrations, agent requirements, log retention and analyst support in the actual offer. A list of device categories does not establish agent support on every platform. Cloud management alone does not establish compatibility or a local round-the-clock service.
Validate vendor answers in a pilot
Agree expected outcomes and approved test scenarios before the pilot. Compare the evidence collected through the following checks with your requirements.
| Check | What to test | What to record |
|---|---|---|
| Compatibility and deployment | Representative approved devices and installation | Supported versions and installation issues |
| Operational impact | Ordinary business workloads | Observed resource use and disruption |
| Policy exceptions | An approved allow or exception scenario | Approval owner and resulting behaviour |
| Investigation and response | A harmless agreed alert scenario | Available context, authorized response actions and report export |
