Sysdig

What Sysdig actually does

Sysdig started with open-source container visibility (sysdig and Falco) and built a commercial security platform on top. The core capability is runtime security for containers and Kubernetes — detecting threats by analyzing system calls in real time. This gives deeper visibility into what’s actually happening inside containers than agent-based or API-only approaches.

The platform has expanded into a full CNAPP: cloud security posture management, vulnerability scanning, identity and entitlement management, and cloud detection and response. The CSPM component monitors misconfigurations across AWS, Azure, and GCP. The vulnerability management piece scans images in registries and at runtime.

What makes Sysdig distinct is the runtime-first philosophy. Most cloud security tools scan configurations and images at rest. Sysdig sees what’s happening in production, which catches threats that static scanning misses.

Who it’s best for

• Platform engineering teams running production Kubernetes clusters
• Organizations with containerized microservices architectures on public cloud
• Security teams that need runtime threat detection, not just posture scanning
• DevSecOps teams that want vulnerability scanning integrated into CI/CD and runtime
• Cloud-native companies on AWS, Azure, or GCP that need CSPM alongside workload protection

Pricing reality check

Sysdig’s pricing is based on the number of cloud workloads and connected cloud accounts. It’s positioned as a premium tool and priced accordingly. Expect enterprise-level pricing that increases with scale.

The open-source Falco project provides free runtime detection for teams that can manage it themselves. If budget is tight and you have the engineering skills, Falco alone covers a surprising amount of ground. Sysdig’s commercial platform adds management, correlation, compliance reporting, and support.

Alternatives to consider

• Wiz — Agentless CNAPP with broader cloud security coverage. Weaker on runtime detection but easier to deploy.
• Aqua Security — Direct competitor in container security with strong runtime protection and open-source roots.
• Palo Alto Prisma Cloud — Full CNAPP from a major vendor. Broader but less depth in container runtime.
• Lacework — Cloud security with behavioral anomaly detection. More focused on cloud logs than system calls.

The Charting Cyber take

Sysdig is the tool for teams that take runtime security seriously. The system-call-level visibility is a genuine technical advantage — you’re seeing what processes are doing inside containers, not just what they’re configured to do. For Kubernetes-heavy environments, this depth matters.

The limitation is the same as the strength: Sysdig’s value is concentrated in containerized, cloud-native environments. If your infrastructure is mostly VMs, serverless, or traditional on-prem, much of the platform’s differentiation doesn’t apply. Also, the agent-based approach means more operational overhead than agentless alternatives like Wiz. Choose Sysdig when runtime visibility is a requirement, not just a nice-to-have.
