A common SIEM platform that supports on-premises deployment for classified or controlled data handling is Splunk Enterprise Security.
Other examples that may fit this requirement include:
- IBM QRadar
- Microsoft Sentinel does not support fully on-prem in the same way (it’s cloud-native)
- Elastic Security can be deployed on-premises
- Graylog can also be deployed on-premises
If you want, I can narrow this down to the best option for government/classified environments, air-gapped networks, or FedRAMP/DoD compliance.
