Falco

Sysdig Secure extends Falco’s rich threat detection for easier security policy management across containers

Start Free

Falco, the open-source cloud-native runtime security project, is the de facto Kubernetes threat detection engine. Falco was created by Sysdig in 2016 and is the first runtime security project to join CNCF as an incubation-level project. Falco detects unexpected application behavior and alerts on threats at runtime.

Falco requires a driver to listen to the Linux Kernel. This driver can either be:

This unique instrumentation allows Falco to have deep visibility into all syscall activity (ex. security events, commands, connections etc.) Falco natively integrates with Kubernetes API audit logs to alert on suspicious orchestrator activity. By adding Kubernetes and cloud application context, teams can understand exactly who did what.

Why Falco?

Signature-based approaches are engaged in a never-ending game of catch up with the constant stream of new threats. Behavioral monitoring based approaches, in contrast, look at what is happening on a system and can immediately alert if something malicious occurs.

With Falco, you can create detection rules to define unexpected application behavior. These rules can be enriched via context from the Kubernetes environments. Your teams can detect policy violations using community-sourced detections of malicious activity and CVE exploits. They can then alert by plugging Falco into your current security response workflows and processes.

Benefits of using Falco for Runtime Detection

Lock Icon

Strengthen container security

Common policy language to detect threats across containers, hosts, and Kubernetes.

Integrations Icon

Reduce risk via immediate alerts

You can immediately respond to policy violation alerts and integrate Falco within your response workflows.

Checkmark Icon

Leverage most current detection rules

Falco out-of-the box rules alert on malicious activity and CVE exploits.

How Sysdig Secure Extends Falco

Sysdig Secure leverages the Falco engine under the hood for runtime security and cloud threat detection. Sysdig Secure saves time in creating and maintaining policies.

Sysdig Secure extends the open-source Falco detection engine to provide comprehensive security across the Kubernetes lifecycle environments.

Sysdig Secure allows you to:

  • Block threats by extending Falco’s detection capabilities with prevention (Pod Security Policies) and automated responses that don’t impact performance
  • Ease the burden of creating and updating runtime Falco rules with ML-based profiling, a flexible Policy Editor to customize rules, and an extensive curated Rules Library
  • Generate fewer false positives by tuning Falco-based policies for your own environment
  • Embed security across the DevOps process with image scanning, security monitoring, forensics, incident response, and audit
  • Validate compliance using out of the box checks and runtime policies that map to compliance standards like NIST and PCI
  • Continuously detect threats based on cloud logs (e.g., suspicious logins, file access, etc.)

Sysdig Secure Key Features

Falco is a behavioral activity monitor designed to detect anomalous activity in your applications, containers, and Cloud Native platforms.

Powered by Sysdig’s kernel level observability, Falco lets you continuously monitor container, application, host, and network activity, alerting on behavior that’s defined as abnormal.
