| Enforcement | Bifrost automatically generates default-deny AppArmor profiles for workloads from their observed behavior. | It uses Linux Security Modules including AppArmor, SELinux, and BPF-LSM, with eBPF for alerts and telemetry carrying container, pod, and namespace identities. |
| Integrations | Listed integrations include Kubernetes, Docker, AWS EKS, Google GKE, Azure AKS, DigitalOcean, GitHub Actions, ArgoCD, Helm, Slack, Microsoft Teams, Prometheus, Grafana, and webhooks. | Project repositories include OpenTelemetry, Prometheus, Kafka, Grafana, ELK dashboards, a GitHub Action, and a Rancher UI extension. |
| Security reporting | Bifrost publishes a security policy inviting vulnerability reports by email and says it acknowledges reports and keeps reporters informed, without committing to fixed response timeframes. | The project asks users to report security vulnerabilities through its security process rather than as public GitHub issues. |
| Support | The contact page says the team responds the same business day and offers a 30-minute demo built around the customer's stack and questions. | Project-level questions can be directed to the maintainer group by email, CNCF Slack, GitHub Discussions, or GitHub Issues. |

In their own words
bifrost security
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.
KubeArmor
KubeArmor is an open-source runtime security system for enforcing policies on cloud-native workloads. It uses Linux Security Modules such as AppArmor, SELinux, and BPF-LSM, with eBPF for alerts, telemetry, and container-process tracking. Policies can restrict process execution, file access, networking operations, and resource use. Container policies support Allow, Audit, and Block actions, with Block as the default; system-call monitoring is audit-only. Kubernetes policies can target pods through labels and label expressions, and rules can match paths, network protocols, capabilities, and system calls. The deployment matrix covers Kubernetes, non-Kubernetes containers, virtual machines, and bare-metal hosts. It lists Kubernetes environments including GKE, AKS, OKE, IKS, EKS, OpenShift, Rancher, and DigitalOcean Kubernetes, but support varies by operating system, architecture, and enforcement mode. Some environments are observability-only, and VMware Tanzu entries are under construction. KubeArmor is a community-governed CNCF Sandbox project. The free plan is free; installation guidance uses Helm and kubectl.
