Tenable One Cloud Security
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.
