Elastic Security brings SIEM and endpoint signals onto the Elasticsearch platform.
Open-source security tools for technical teams
Start with the security control and threat model. Identity, secrets, network access, SIEM and endpoint protection address different risks; combining them in one list does not make them interchangeable.
For security engineers, platform teams, developers and sysadmins building layered controls with inspectable or self-hostable software.
The decision to make
Map every candidate to a defined control, owner and evidence source. Test detection or enforcement with a realistic scenario and document how updates, keys, logs and recovery are managed.
