Falco

Open Source

About Falco

Falco is a cloud native security tool that provides runtime security across hosts, containers, Kubernetes, and cloud environments. It uses custom rules on Linux kernel events and other data sources through plugins, enriching event data with contextual metadata to deliver real-time alerts. Falco enables the detection of abnormal behavior, potential security threats, and compliance violations. It collects event data from a source and compares each event against a set of rules. Falco was originally developed as open source by Sysdig and was contributed to the Cloud Native Computing Foundation in 2018.

Used for

  • Detecting malicious behavior in hosts and containers using eBPF.
  • Monitoring compliance in cloud-native systems using rule-based detection.
  • Monitoring cloud services such as GitHub, Okta, or AWS Cloudtrail using plugins.
  • Forwarding Falco alerts to SIEM and data lake systems for analysis, storage, or reaction.

How to evaluate Cloud Security & CSPM

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Falco. It comes from our Cloud Security Posture Management (CSPM) buyer guide.

25%
Risk Prioritization & Attack-Path Analysis
Context graph that correlates misconfiguration, internet reachability, identity/permissions, vulnerabilities, secrets, and data sensitivity into ranked attack paths to crown-jewel assets; toxic-combination detection; quality of the “fix these 10” output versus raw finding volume; false-positive rate in your own accounts
20%
Coverage Model: Agentless Breadth vs. Runtime Depth
Agentless snapshot/API scanning for fast 100%-estate visibility versus agent/eBPF runtime for in-production threat detection (CDR); container, serverless, and Kubernetes (KSPM) coverage; how the two models combine without double-counting; performance impact and deployment friction
20%
Multi-Cloud & Platform Consolidation (CNAPP)
Depth and parity across AWS, Azure, GCP, OCI, and Kubernetes from one console; how many of CSPM, CIEM, CWPP, DSPM, KSPM, and code/IaC security are genuinely unified on one data model versus bolted-on acquisitions; single policy and one risk score across domains
15%
Identity & Entitlements (CIEM)
Effective-permission analysis across human and machine identities, cross-account and federated role mapping, detection of unused and over-privileged entitlements, least-privilege right-sizing recommendations, and privilege escalation / lateral-movement path discovery
10%
Remediation, Automation & Developer Workflow
Guided and auto-remediation, IaC and pull-request fixes (shift-left to code), guardrails that prevent drift, ticketing/SOAR integration, ownership routing to the right team, and API/Terraform coverage for security-as-code
10%
Compliance, Reporting & SOC Integration
Out-of-the-box frameworks (CIS, PCI DSS, HIPAA, SOC 2, FedRAMP, NIST) with custom policy authoring, audit-ready evidence and drift history, RBAC/SSO on the console, and clean export of correlated cloud risk into the SIEM/SOC rather than a siloed dashboard
