Kubernetes Cluster Security Scanners

Checkov is a static analysis tool and security scanner designed to identify misconfigurations in infrastructure as code, container images, and Kubernetes configurations. It functions as a cloud security posture tool, an SCA vulnerability scanner, and a secret scanning utility to prevent security breaches and version control leaks. The project distinguishes itself through deep graph analysis and variable resolution, allowing it to map relationships between interconnected resources and evaluate the final state of infrastructure attributes. It provides extensibility for defining custom security

Trivy is a comprehensive security scanner designed to identify vulnerabilities and misconfigurations across container images, filesystems, and infrastructure as code files. It functions as a software composition analysis tool and an infrastructure security scanner, providing automated checks for CI/CD pipelines and cloud environments to ensure the integrity of the software supply chain. The tool distinguishes itself through a modular, plugin-based architecture that allows for the independent inspection of diverse targets. It utilizes a declarative policy engine to evaluate configurations agai

Kubescape is a security platform for Kubernetes that provides tools for scanning clusters, configurations, and container images against industry compliance and security benchmarks. It functions as a suite of security utilities, including a compliance auditor, a misconfiguration scanner, and a container vulnerability scanner. The project differentiates itself through automated remediation and active enforcement. It can automatically patch operating system vulnerabilities in images and fix security errors within manifest files. It also utilizes an admission controller to block the deployment of

ThreatMapper is a cloud native application protection platform and infrastructure security scanner. It functions as a vulnerability management system and cloud workload telemetry collector designed to monitor workloads and detect security risks across cloud and container environments. The platform distinguishes itself through a network traffic visualizer that uses machine learning to classify communication patterns and a graph-based attack mapping system to identify high-risk paths between vulnerabilities and network dependencies. Its broader capabilities cover cloud infrastructure complianc

Kubescape is a Kubernetes security posture management platform designed to scan clusters, manifests, and images for misconfigurations, vulnerabilities, and compliance risks. It functions as a comprehensive security suite incorporating a compliance scanner, a container image vulnerability scanner, an admission controller for policy enforcement, and a runtime security monitor. The platform distinguishes itself through runtime-aware vulnerability filtering, which maps libraries loaded in memory to determine if vulnerabilities are actually reachable. It also integrates with AI assistants via a Mo

Kubernetes-native security toolkit

Kube-hunter is a security scanner and vulnerability hunter for Kubernetes clusters. It operates as a cloud-native penetration tool designed to identify security weaknesses, infrastructure misconfigurations, and exploitable gaps by simulating attacker techniques. The tool distinguishes itself through a dual-mode scanning engine that executes both remote external probes and internal network scans. It features identity-based impersonation, allowing it to use service account tokens and pod identities to simulate security access from specific cluster roles and determine the potential blast radius

kube-bench is a Kubernetes security benchmark scanner and configuration auditor. It verifies if a cluster adheres to the Center for Internet Security standards and other hardening guides to identify security misconfigurations and vulnerabilities. The tool operates as a containerized security scanner, utilizing host namespaces to analyze nodes and control plane components without requiring the installation of binaries directly on the host. It supports multiple Kubernetes distributions, applying environment-specific benchmarks to ensure auditing accuracy for managed services. The project cover
