Kubernetes and container security

Automatically detect, prioritize, and remediate critical issues to enhance your Kubernetes cluster’s security posture.

Trusted by 800+ companies globally

Key features

Automatic risk remediation and prioritization

Attack path

Trace the potential paths attackers could take and safeguard critical assets:

  • Identify and prioritize remediation for misconfigurations and vulnerabilities that expose workloads to threats
  • Stay secure with ongoing analysis of evolving attack paths as your cluster changes, ensuring up-to-date defenses

Security posture

Continuously scan cluster images to identify vulnerabilities across each image layer:

  • Remediate multiple vulnerabilities using recommended base images
  • Use comprehensive reports with layer-by-layer analysis to efficiently prioritize vulnerabilities

Runtime security

Cast AI leverages eBPF probes to monitor runtime activity, detecting signals like privilege escalations and network anomalies without impacting performance:

  • Define specific anomaly detection rules tailored to your environment for precise monitoring and threat prevention
  • Generate detailed, real-time alerts with contextual data to enable rapid incident response and root cause analysis

Setup

Get started in three steps

Select your provider and run a single script to deploy a lightweight, read-only agent that will analyze your cluster.

Automatically scan container images, generate in-depth vulnerability reports, and get recommendations to fix them.

Prioritize fixes and identify misconfigurations and vulnerabilities across all Kubernetes resources.

FAQ

Your questions, answered

What is Kubernetes security and why is it important?

Kubernetes security is all about protecting the Kubernetes cluster and workloads from threats by addressing misconfigurations and vulnerabilities. It’s crucial for keeping applications secure and achieving compliance with required standards.

How can I secure Kubernetes clusters?

You can secure your K8s cluster by implementing network policies, limiting API access, encrypting sensitive data, and using container security tools to scan container images and instantly identify any vulnerabilities or misconfigurations that may put your cluster at risk.

What are Kubernetes security best practices?

Security best practices for Kubernetes include using least privilege access, isolating workloads, applying network policies, scanning container images for vulnerabilities, and enabling logging and monitoring for security events.

How do you secure container images in Kubernetes?

You can secure container images by using trusted base images, scanning images for vulnerabilities, regularly updating images, and using signed images.

What are the key components of Kubernetes security?

Key components include securing the Kubernetes API server, managing authentication and authorization, implementing network policies and runtime security, and properly configuring secrets and RBAC (Role-Based Access Control).

What are common Kubernetes security vulnerabilities?

Common K8s vulnerabilities include insecure API access, exposed secrets, misconfigured RBAC, privilege escalation attacks, unscanned container images, and lack of network isolation.

How does network security work in Kubernetes?

Kubernetes network security uses network policies to control traffic between pods and services. You can define rules to restrict communication based on IP addresses, ports, or labels to prevent unauthorized access.

What are the main challenges in Kubernetes security?

Key challenges include managing complex access control (RBAC), securing dynamic and ephemeral workloads, ensuring secure communication between services, protecting sensitive data (secrets), and handling vulnerabilities in container images. Keeping up with security patches and configurations in fast-evolving Kubernetes environments can also be difficult.
