C3M Cloud Control vs Tenable One Cloud Security

C3M Cloud Control is an agentless platform for cloud security, identity and entitlement governance, and compliance assurance. It continuously assesses multicloud infrastructure for security and compliance risks and can remediate them. Access Control manages identity entitlements and enforces least privilege, with inventory, access-key monitoring, excessive-permission detection, audit timelines, policy enforcement, and one-click remediation for unused entitlements. Playbooks for AWS, GCP, and Azure can remediate resources, notify administrators, create incident tickets, and send violations to SIEM tools. Customers can add custom actions using cloud functions in languages including Java, Node.js, and Python. Compliance monitoring evaluates resources against PCI, GDPR, NIST, CIS, FedRAMP, HITRUST, and HIPAA, and supports custom packages. Its IaC module scans Terraform templates; support for CloudFormation, ARM, Kubernetes, and other IaC templates is described as coming soon. It offers a free assessment for up to two cloud accounts. The main plan’s price is available on request.

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.
