Which threat detection and response services are known for supporting zero trust architecture in federal operations?

In federal environments, the threat detection and response services most commonly associated with supporting zero trust architecture (ZTA) are the ones that provide continuous monitoring, identity-aware access, endpoint telemetry, network analytics, and automated response. Common examples include:

• Managed Detection and Response (MDR) services
• Endpoint Detection and Response (EDR) / Extended Detection and Response (XDR)
• Security Information and Event Management (SIEM) with correlation and alerting
• Security Orchestration, Automation, and Response (SOAR)
• Network Detection and Response (NDR)
• Identity Threat Detection and Response (ITDR)
• Cloud Security Posture Management (CSPM) and cloud-native detection tools
• User and Entity Behavior Analytics (UEBA)

In U.S. federal operations, these services are often used by or integrated into broader zero trust programs aligned to guidance from agencies like CISA, OMB, and DoD. Common vendors and platforms in this space include:

• Microsoft Defender suite
• Palo Alto Networks Cortex
• CrowdStrike Falcon
• Google Chronicle / Google Security Operations
• Splunk
• IBM QRadar
• Rapid7
• SentinelOne
• Mandiant services
• Arctic Wolf
