How to choose

What data sources does it need to cover?

Choose a tool that can work with the data sources you need to monitor. Compare data source coverage before weighing features such as log search or automated response.

Where does it need to run?

Check deployment and platform support against your environment. The platform labels on this board include web, Linux, API, Windows, self-hosted and macOS.

How should it alert or respond to threats?

Compare alerting channels and whether automated response is available. These are separate capabilities, so consider which ones fit the way your team handles security events.

How long should it retain security data?

Compare data retention alongside log search. The right fit depends on how long you need records to remain available and how you plan to find them.

Can I try it or start with a free plan?

Check the free-plan and trial details, then compare paid pricing. Elastic Security lists a free plan, paid pricing from $0.09 and a 14-day trial; Amazon GuardDuty lists a 30-day trial without a free plan.
