Highly dynamic and configurable K8s causes security issues

Security risks have become more prominent, as development teams accelerate their use of Kubernetes to achieve speed and efficiency goals.

Complex environments obstruct visibility

Complex environments obstruct visibility

The dynamic nature of K8s creates complexity and blind spots for security and compliance. Secure K8s with comprehensive visibility.

Rules alone cannot protect against threats

Rules alone cannot protect against threats

Rules only find known risks, and can break in K8s environments. Automate security to detect unknown threats without writing complex rules.

Alerts without context are just noise

Alerts without context are just noise

Hundreds or thousands of alerts overwhelm security. Accelerate response time with only a few alerts that provide valuable security context.

Run Kubernetes with confidence

Accelerate Kubernetes and container usage with security and compliance control from build to runtime, across K8s control and data planes.

  • Secure from the beginning

    Automate guardrails at every stage of the cloud-native application lifecycle and prevent misconfigured K8s resources from being deployed.

  • Deliver secure applications on time

    Empower developers and DevOps teams to secure applications effortlessly within existing workflows and avoid last-minute security delays.

  • Uncover hidden runtime threats

    Gain immediate visibility into unusual behavior and previously unknown and zero-day threats within K8s and running container workloads.

Our Approach

Comprehensive Kubernetes security

Harden K8s security posture, find vulnerabilities, and automatically detect unusual behavior and runtime threats without writing rules.

Secure K8s early in software lifecycle

  • Rapidly find and fix vulnerabilities and misconfigurations within Kubernetes Manifest, Helm, Terraform, and more.
  • Automate security and compliance guardrails at each commit and pull request within GitHub and GitLab repositories.
  • Boost developer productivity with actionable findings and guided remediation that are tightly integrated within existing toolchains and workflows.
  • Dramatically reduce cloud risk by preventing non-compliant and misconfigured Infrastructure as Code from being deployed.

Focus on image risks that matter most

  • Correlate multiple risk factors and combine build and runtime insights to identify which image vulnerabilities matter most in your environment.
  • Automatically detect or block non-compliant container images through the Kubernetes Admission Controller before they are deployed.
  • Perform fast on-demand scans of container images or schedule every 15 minutes using auto-polling.
  • Continuously scan new and existing images within public and private registries.

Harden K8s security posture (KSPM)

  • Automatically discover all Kubernetes assets and resources including workloads, pods, nodes, and more.
  • Harden security posture (KSPM), enforce least privilege, protect secrets, ensure containers are not running as root, and more.
  • Quickly assess compliance with industry best practices and regulations including CIS, HIPAA, ISO, NIST, PCI, and SOC 2.
  • Track assets for 90 days and monitor how workloads, RBAC, and other resource configurations drift over time.

Detect threats in Kubernetes runtime

  • Continuously monitor node, container, and K8s runtime activity and detect malicious behavior that may indicate container escape, lateral movement, and more.
  • Know how K8s clusters, namespaces, and containers are communicating with cloud services, external domains, and other K8s resources.
  • Visualize K8s clusters’ network activity, processes, user behavior, and topology with patented Polygraph® technology.
  • Get automatic alerts on unusual activity and detect unknown threats and zero-day exploits.

Know exactly who is doing what in K8s

  • Continually collect and analyze a massive number of K8s API calls and gain visibility into all user and resource activities.
  • Automatically detect user activity, K8s RBAC, deleted resources, authentication errors, forbidden API calls, and more.
  • Visualize and trace API calls between the source IP address, K8s, and AWS groups and usernames, target resources, and more.
  • Intelligently query Polygraph using multiple terms like actions, namespace, and resource names to focus on specific activity paths.

What is Kubernetes security?

Kubernetes security prevents internal and external threats from compromising the containers and workloads within your Kubernetes environment. It also quickly detects exploits of vulnerabilities and misconfigurations, and monitors and secures the environment to comply with frameworks and regulations.

Why is Kubernetes security important though the container lifecycle? Add Media

Since K8s environments can be challenging to secure given their size, velocity, and ephemeral nature, it is vital to have layered defenses from build through runtime. Effective Kubernetes security offers threat detection, configuration management, and vulnerability checks across the environment.

What are Kubernetes security best practices?

Implementing Kubernetes security best practices can help with the challenges of securing ephemeral environments. Here is a checklist of ten best practices:

  • Monitor and fix IaC at check-in
  • Perform container configuration and vulnerability checks at build time
  • Use strict roles-based access control (RBAC)
  • Harden and isolate nodes and OSes
  • Monitor network connections
  • Monitor ingress endpoints
  • Deploy runtime, agent-based monitoring for host OS and K8s components
  • Monitor Kubernetes audit logs
  • Monitor deployment of new components and workloads
  • Use automation for threat detection
