Fidelis Halo is a cloud-native application protection platform (CNAPP). The platform includes three configurable services: Cloud Security Posture Management (CSPM), Cloud Workload Protection Platform (CWPP), and full-stack container security. Fidelis Halo provides real-time discovery, inventory, and assessment across clouds, on-premises, and virtual environments, detecting misconfigurations, configuration drift, vulnerable servers, and indicators of compromise. A microagent architecture offloads workload security functions including storage, memory, and computer scaling to the Fidelis Halo Cloud centralized agent framework. The platform's Heartbeat Monitoring runs near-real-time without requiring snapshots. Fidelis Halo integrates with CI/CD automation tools such as Puppet, Chef, and Jenkins, SIEMs such as Sumo Logic and Splunk, GRC solutions, and various analysis and reporting tools. The platform provides lifecycle cybersecurity workflows that enable a DevSecOps operating model.
