Calico Enterprise vs OpenCNAPP

Calico Enterprise is a self-managed platform for network security and observability in Kubernetes clusters. It provides pod-to-pod networking within single clusters and across multiple clusters, with data-plane options including eBPF, nftables, iptables, Windows, and VPP. Cluster mesh connects clusters for pod communication and service discovery, while supporting policy enforcement and traffic visibility. Security controls include network- and application-layer policies, DNS policies, egress controls, and workload microsegmentation. It also provides workload-level IDS/IPS, a workload-focused WAF, and DDoS detection and prevention. For observability, Calico combines flow logs with Kubernetes context and offers network topology views, dashboards, alerts, and workload packet capture. Tigera lists support for PCI DSS, HIPAA, GDPR, SOC 2, NIST, CCPA, and custom compliance frameworks, along with continuous monitoring and audit-ready reports. Policy deployment can integrate with CI/CD tools such as ArgoCD and Jenkins. The product supports hybrid deployment and centralized control, with BGP, IP-in-IP, VXLAN, WireGuard, TCP, UDP, SCTP, ICMP, ICMPv6, and HTTP listed as supported protocols.

OpenCNAPP is an open-source cloud-native application protection platform from Xcitium, LLC Cybersecurity Company. It is listed as free and self-hosted, while deployment descriptions include SaaS and on-premises models across public, private, hybrid and air-gapped environments. The platform covers cloud environments, clusters, containers, code repositories, Kubernetes and virtual machines from build through runtime. It provides agentless cloud posture management, multi-cloud visibility, misconfiguration and drift detection, and continuous compliance, auditing and reporting. Pipeline capabilities include static code analysis, CI/CD scanning, container and Kubernetes security, and secret scanning. Runtime protection uses eBPF- and LSM-powered workload controls, with container visibility, application and network firewalls, and in-line mitigation. OpenCNAPP also lists Zero Trust policy generation, observe, audit and enforce controls, integrations across registries, notifications, SIEM, ticketing, EDR, AppSec and SOAR, plus IoT, edge, 5G and federal workload coverage.
