bifrost security vs Tetragon

Bifrost Security provides runtime security for containerised workloads, using observed behaviour to assess CVEs and generate workload-specific protections. Its agent monitors system calls, file access, signals, capabilities, and network ports at kernel level without requiring code changes. For each CVE, Bifrost reports whether it is reachable, mitigated by a security profile, or never loaded, and provides evidence for the verdict. The agent collects behavioural metadata only; Bifrost says it does not collect application data or personal information. The product can ingest CycloneDX and SPDX SBOMs and rescan them for CVEs across environments. It also creates default-deny AppArmor profiles from observed workload behaviour. Deployment is as a DaemonSet via Helm, with stated resource use below 200 MB RAM per node and below 1% performance impact. Bifrost supports Kubernetes, Docker Swarm, and Nomad workloads. A 14-day trial includes the full Pro edition and requires no credit card. Pricing is on request. The company is based in Stockholm, Sweden.

Tetragon is a Kubernetes-aware security observability and runtime enforcement tool for Linux, container, and Kubernetes workloads. It uses eBPF to monitor activity, filter events, and enforce policies in the kernel in real time. Process reports can include executed binaries, command-line arguments, user IDs, parent processes, and start times. Tetragon also monitors file access and changes, and can block unauthorized file operations at the kernel level. Kubernetes policies can filter activity by namespace, pod labels, and container fields, with support for containerd and CRI-O. Network visibility ties events to processes and workloads and tracks connections, socket lifecycle, and bytes sent or received. The tool also monitors credential changes, kernel module activity, and eBPF program loads and interactions. Findings are available as JSON logs or through gRPC. Installation options include Helm on Kubernetes, released Linux packages, and a container image. Tetragon is a Cilium sub-project and a CNCF project, and is available as an open-source project with no paid plans listed.
