Compare Microsoft Sentinel with CrowdStrike
On this page
Microsoft Sentinel and CrowdStrike Falcon Next-Gen SIEM often meet in the same evaluation, especially in organizations that run Microsoft 365 alongside the Falcon agent. Both are cloud SIEMs with AI built in, but each is shaped by its parent ecosystem.
Microsoft Sentinel in brief
Sentinel is Microsoft’s cloud-native SIEM and SOAR. It is moving fully into the Microsoft Defender portal, and Microsoft has said it will no longer be supported in the Azure portal after March 31, 2027. The Sentinel data lake adds lower-cost long-term retention, and Security Copilot can work on Sentinel data.
CrowdStrike in brief
CrowdStrike Falcon Next-Gen SIEM extends the Falcon endpoint platform into log management and detection. It works with Charlotte AI, an agentic security analyst, and Charlotte Agentic SOAR for orchestration.

Key differences that matter
Sentinel shines when identity, email, and productivity data already sit in Microsoft. CrowdStrike is strongest when the endpoint is where most investigations start.
In both cases, ingest cost and the amount of manual triage left for analysts are the factors most likely to tip the decision.
Where Exaforce fits alongside Microsoft Sentinel and CrowdStrike
Exaforce can replace a SIEM or run alongside either platform. Its Data Platform includes intelligent storage tiering, and its AI agents, called Exabots, triage, investigate, and respond from a model of identities and resources built at ingest. That helps teams that use both vendors and want one consistent view across them.
Choosing between them
Look at where your highest-value telemetry lives, then compare the full bill and the analyst workload in a pilot on your own data.
