Qualys TotalCloud vs Tetragon

Qualys TotalCloud is a cloud-native application protection platform for multi-cloud and container environments. It covers AWS, Azure, Google Cloud Platform, and Oracle Cloud Infrastructure through a single license, control plane, and TruRisk score. Its security domains include CSPM, CWPP, CIEM, CDR, Kubernetes and container security, IaC, SSPM, DSPM, and AI-SPM. TruRisk prioritizes verified, attackable exposures using exploitability, threat intelligence, asset criticality, and runtime context. FlexScan offers agentless, agent-based, network, and pipeline scanning. QFlow provides more than 300 automated playbooks and integrates with ServiceNow, Jira, SIEM, and SOAR platforms. Qualys says TotalCloud can assess cloud resources, including transient and ephemeral resources, in under 10 minutes. It also manages SaaS security posture for Microsoft 365, Salesforce, Zoom, and Google Workspace. Pre-built policy frameworks include CIS, PCI-DSS, HIPAA, and NIST. A free license with limited API calls for control evaluation is listed; subscription pricing is available on request.

Tetragon is a Kubernetes-aware security observability and runtime enforcement tool for Linux, container, and Kubernetes workloads. It uses eBPF to monitor activity, filter events, and enforce policies in the kernel in real time. Process reports can include executed binaries, command-line arguments, user IDs, parent processes, and start times. Tetragon also monitors file access and changes, and can block unauthorized file operations at the kernel level. Kubernetes policies can filter activity by namespace, pod labels, and container fields, with support for containerd and CRI-O. Network visibility ties events to processes and workloads and tracks connections, socket lifecycle, and bytes sent or received. The tool also monitors credential changes, kernel module activity, and eBPF program loads and interactions. Findings are available as JSON logs or through gRPC. Installation options include Helm on Kubernetes, released Linux packages, and a container image. Tetragon is a Cilium sub-project and a CNCF project, and is available as an open-source project with no paid plans listed.
