Introduction
eBPF observability and runtime security tools enable deep visibility into system behavior by running safe, lightweight programs directly inside the operating system kernel. This allows teams to monitor applications, network traffic, and system calls without modifying application code or adding heavy instrumentation.
These tools are transforming modern observability by providing low-overhead, real-time telemetry across distributed systems, especially in Kubernetes and cloud-native environments. They are also widely used for runtime threat detection, anomaly monitoring, and security enforcement.
Common use cases include Kubernetes observability, performance profiling, runtime threat detection, network monitoring, and forensic analysis.
What buyers should evaluate:
- Depth of kernel-level visibility
- Performance overhead and efficiency
- Security detection and enforcement capabilities
- Integration with Kubernetes and cloud platforms
- Ease of deployment and automation
- Observability coverage metrics logs traces profiling
- Policy and runtime enforcement features
- Scalability for distributed systems
- Ecosystem maturity and community
- Compatibility with modern DevOps workflows
Best for: DevOps teams, SREs, platform engineers, security teams, and enterprises running Kubernetes or cloud-native systems.
Not ideal for: Small applications without complex infrastructure or teams not requiring deep system-level visibility.
