Microsoft and CrowdStrike offer strong ITDR capabilities but they typically depend on their own ecosystems, higher licence tiers or separate SIEM/SOAR tooling. Huntress focuses mainly on Microsoft 365 identities.
Heimdal ITDR is designed to be more flexible: it correlates identity, email, endpoint, DNS and remote access data in one place, adds built-in privilege security controls on the endpoint, and can be run either by your own team or as a managed SOC service through Heimdal MXDR (Managed XDR).
