OpenCNAPP

OpenCNAPP is an open-source platform for protecting cloud-native applications from build through runtime. It combines agentless cloud posture management with eBPF- and LSM-powered workload protection, covering cloud environments, clusters, containers, code repositories, Kubernetes, and virtual machines. Listed monitoring includes multi-cloud visibility, misconfiguration and drift detection, and ongoing compliance, auditing, and reporting. Pipeline tools include static code analysis, CI/CD scanning, container and Kubernetes security, and secret scanning. Runtime capabilities include container visibility, application and network firewalling, and in-line mitigation. Teams can generate Zero Trust policies and configure observe, audit, or enforce controls. The platform lists integrations with container registries, notification tools, SIEM products, ticketing tools, EDR, AppSec, and SOAR. Deployment options include SaaS and on-premises, with public, private, hybrid, and air-gapped environments. OpenCNAPP also describes protection for IoT, edge, and 5G workloads. It is listed as free and open source, and identifies itself as part of Xcitium, LLC.

OpenCNAPP spans cloud posture, pipeline checks, and runtime protections, with deployment options ranging from SaaS to air-gapped environments. Its extensive scope is relevant to teams seeking coverage across cloud-native workloads and code.

OpenCNAPP may suit teams responsible for cloud, Kubernetes, container, or code security across build and runtime. Its listed deployment options include air-gapped environments and on-premises setups.

OpenCNAPP is an open-source security platform for protecting cloud-native environments from code and deployment through runtime. It is best suited to teams that need broad Kubernetes and cloud coverage, including self-hosted or air-gapped deployments. Its breadth is compelling, but teams should be ready to manage a platform that spans many security jobs.

Overview

OpenCNAPP brings cloud posture management, workload protection, container security, and pipeline checks into one platform. It covers cloud environments, clusters, containers, code repositories, Kubernetes, and virtual machines, with additional support for IoT, edge, and 5G workloads. That range can help security teams connect issues found during development with protections applied in production.

Deployment options include SaaS and on-premises, across public, private, hybrid, and air-gapped environments. The flexibility is useful for organizations with strict infrastructure or government requirements, though self-hosting may mean more operational responsibility than a SaaS-only product.

Key features

Cloud posture and policy

Agentless CSPM provides multi-cloud visibility, misconfiguration and drift detection, and continuous compliance monitoring, auditing, and reporting. Automated Zero Trust policy generation and configurable observe, audit, and enforce controls let teams choose how firmly to apply policies. That flexibility supports gradual adoption; teams seeking a narrowly focused posture scanner may find the overall scope broader than they need.

Workload and runtime protection

OpenCNAPP combines agentless posture management with eBPF- and LSM-powered workload protection. It offers container visibility, application and network firewalling, and in-line mitigation. Kubernetes security is central, while virtual machines, IoT and edge systems, and 5G workloads extend the reach beyond containers. For IoT and edge, it includes systemd deployment and hardening recommendations; for 5G, it describes control-plane hardening, third-party xApp protection, and microsegmentation.

Build pipeline and secrets

Pipeline capabilities cover static code analysis, CI/CD scanning, container and Kubernetes security, and secret scanning. CyberArk Conjur hardening restricts pod access to secret mount points and allows selected paths for selected processes. Together, these controls are relevant to teams that want security checks to reach into development workflows as well as runtime.

Integrations and standards

OpenCNAPP cites integrations with more than 11 container registries, 3 notification tools, 4 SIEM products, and 4 ticketing tools, along with EDR, AppSec, and SOAR integration. It says its platform meets or aligns with SOC 2, STIG, PCI, HIPAA, CIS, MITRE, and NIST standards or frameworks, and references ENISA and GDPR in IoT and edge hardening recommendations. These connections and framework coverage may suit organizations coordinating controls across established security and compliance workflows.

Pricing

OpenCNAPP is free and open source, with a free plan. That makes it a plausible choice for teams seeking broad capabilities without a software subscription. No seat, quota, trial, or renewal terms are stated, so buyers should not assume those details from the free label alone.

Platforms

The listed platform is self-hosted. Deployment models also include SaaS and on-premises, with public, private, hybrid, and air-gapped options. Teams with US government security needs may value its advertised federal workload protection and secure air-gapped deployment.

Who it's for

OpenCNAPP is best suited to security and platform teams responsible for cloud-native workloads across build and runtime, especially those running Kubernetes alongside virtual machines or operating in private, hybrid, edge, 5G, or air-gapped environments. It is less suited to buyers who want a focused tool or a clearly priced commercial service with defined plan limits.

Pros and cons

• Pros: Broad coverage links cloud posture, pipeline scanning, container security, and runtime protection in one platform.
• Pros: SaaS, on-premises, and air-gapped deployment options can accommodate varied infrastructure and government requirements.
• Pros: Configurable observe, audit, and enforce controls allow teams to choose how policies are applied.
• Cons: Its wide scope may be more than teams need if they are looking for a single-purpose scanner.
• Cons: Self-hosted deployment is the listed platform, so teams should weigh its operating needs against the convenience of a managed service.

Alternatives

Qualys TotalCloud is a paid option with a free license limited to API calls for control evaluation; choose it if that evaluation-focused free tier fits your needs.

Palo Alto Networks Cortex Cloud API Security, Upwind CNAPP, and FortiCNAPP are paid alternatives.

Sysdig Secure is a paid alternative with licensing based on host count, including compute instances for CSPM. Wiz Defend is paid, has no free plan, and uses modular quote-based licensing.

AccuKnox offers a free plan and custom pricing based on the environment, with pay-as-you-go options for individual modules or a comprehensive CNAPP bundle.

Cloudanix is a paid alternative with a free trial; its Cloud Pro Posture plan costs $3.49 a month per monitored asset, billed at month-end, with a 100-asset minimum.

Verdict

OpenCNAPP is a strong fit for teams that want an open-source platform spanning cloud posture, code pipelines, and runtime protection, especially when self-hosted or air-gapped deployment matters. Its breadth is the main reason to choose it; teams that need a narrower product or prefer a defined commercial plan should compare the paid alternatives.
