Open-source alternatives to Kube Linter

Security risk analysis for Kubernetes resources

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

Kubernetes RBAC static analysis & visualisation tool

CLI tool for linting and testing Helm charts

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

Review Access - kubectl plugin to show an access matrix for server resources

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

Grype is a command-line security scanner designed to identify known vulnerabilities within container images, filesystems, and software manifests. It functions as a software composition analysis tool that detects security flaws in application components and open-source libraries to support supply chain security. The tool distinguishes itself by reconstructing the final state of container images through layered filesystem inspection and normalizing diverse package formats into a unified dependency graph. It maintains a local cache of security advisories synchronized from multiple upstream sourc

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

A best practices checker for Kubernetes clusters. 🤠

External Secrets Operator reads information from a third-party service like AWS Secrets Manager and automatically injects the values as Kubernetes Secrets.

Datree is a policy enforcement framework for Kubernetes that validates configurations against rules written in Rego, JSON Schema, or CEL. It operates as both a command-line tool for pre-deployment scanning and as a cluster-side admission webhook for real-time enforcement, integrating with CI/CD pipelines and continuous delivery tools like ArgoCD and FluxCD. The framework supports namespace-scoped policy mapping, allowing different policies to apply to different namespaces, and provides a skip annotation mechanism for selectively bypassing rules on individual resources or entire namespaces. It

kubeaudit helps you audit your Kubernetes clusters against common security controls

World's first fully integrated and fully Automated Kubernetes management and orchestration solution

Kubernetes Goat is a security training environment designed for practicing the identification and exploitation of common vulnerabilities within an intentionally insecure cluster. It provides a controlled setting to simulate system exploitations, including container escapes, role misconfigurations, and server-side requests. The project utilizes scenario-based vulnerability deployment to create specific security flaws. It includes utilities for environment management that allow the cluster to be restored to a clean baseline by removing vulnerable scenarios, service accounts, and role bindings.

Freelens is a graphical web dashboard for Kubernetes cluster administration and monitoring. It provides a centralized interface for managing container orchestration environments, featuring a log aggregator for simultaneous multi-pod log viewing, a resource visualizer for mapping system dependencies via force-directed graphs, and a security auditor for reviewing vulnerability reports and certificate expiration dates. The project integrates a generative artificial intelligence operator to automate complex administrative tasks and translate requests into cluster configurations. It further distin
