OpenCNAPP vs Tenable One Cloud Security

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.

Tenable One Cloud Security, described in the product details as Tenable One Cloud Exposure, is a CNAPP for finding and reducing risk across multi-cloud and hybrid environments. It discovers cloud compute, identity, and data assets, then maps access and exposure paths. Risk prioritization covers misconfigurations, excessive permissions, vulnerabilities, and exposed sensitive data. Infrastructure-as-code scanning checks Terraform, CloudFormation, and Kubernetes manifests for misconfigurations, compliance gaps, and policy violations. The platform integrates with AWS, Azure, and GCP, plus services such as AWS Control Tower and Entra ID. Identity integrations include Google Workspace, Okta, OneLogin, and Ping Identity; workflow connections include Jira, Slack, Microsoft Teams, email, ticketing, notification, and SIEM tools. It checks against CIS, NIST, and PCI DSS frameworks and provides guided remediation. Tenable says optional in-account scanning keeps scan data in the customer cloud. The paid product has no free plan or trial. Pricing is customized by billable cloud resources and is available standalone or as part of Tenable One.
