Palo Alto Networks Cortex Cloud API Security vs Tenable One Cloud Security

Palo Alto Networks Cortex Cloud API Security discovers, ranks, and protects APIs across cloud environments. It can find and validate APIs across gateways, workloads, and cloud environments, including shadow, zombie, and unmanaged APIs. Configuration and traffic context inform risk rankings based on severity and potential business impact. Risk insights cover internet exposure, sensitive data transmission, weak authentication, missing encryption, and specification drift. The product describes real-time protection against OWASP API Top 10 threats, including injection, authentication bypass, and data exposure; teams can use monitor or blocking modes. Agentless integrations are listed for AWS API Gateway, Azure APIM, GCP Apigee, and Kong. Linux workload protection uses an agent and is marked Beta. Teams can import OpenAPI specifications to check live traffic for deviations and scan for misconfigurations or vulnerabilities. Azure APIM integration requires the Data Collection add-on and a running Azure APIM service. Cortex CLI scans require an OpenAPI file and Java 11 or later, while Web and API Security requires the Runtime Security add-on. Pricing is on request; the product page offers a demo 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.
