SECURITY ATLAS / EVALUATION BRIEF Sysdig Research reviewed: 2026-10-18 https://atlasofsecurity.com/landscape/vendors/sysdig/ THE ATLAS TAKE Sysdig is a serious evaluation candidate when Linux and Kubernetes runtime behavior must explain why a cloud finding matters. Its documentation is particularly useful because it exposes the collection work behind the promise: cloud-account integrations, agents, host scanners, and cluster components have distinct jobs. Atlas would judge the platform on one maintained investigation and remediation loop, not on the mere presence of runtime telemetry. Kernel support, component upgrades, metadata enrichment, and policy behavior can determine whether a feature is usable in production. A posture-only connection should be evaluated on its own evidence rather than credited with agent-dependent runtime visibility. SCOPE Runtime sensing, posture and Kubernetes assessment have different deployment requirements. Falco and eBPF-related detection require supported instrumentation; an API-only posture connection does not provide the same process visibility. Verify kernel, cluster and workload support before rollout. WORTH A LOOK WHEN Cloud-native teams with Linux and Kubernetes ownership who want runtime evidence connected to vulnerability and posture decisions. THINK TWICE WHEN Cluster operators cannot support instrumentation, or the required workload and kernel combinations are outside the documented support path. IMPLEMENTATION 1. Choose a supported cluster slice Record kernel, orchestrator, workload type, outbound connectivity, and the exact components needed for the intended controls. 2. Stage observability before enforcement Validate metadata and permitted activity first, then enable one approved restrictive policy with a rollback plan. 3. Make upgrades observable Track component versions, failed installation, missing nodes, and a repeatable health check through a cluster upgrade. OPERATING REALITY Cluster and host operators manage component installation, credentials, upgrades, and resource impact; security engineers maintain policies and investigation workflows. Atlas would budget for these responsibilities explicitly. A healthy account connector is different from a healthy runtime agent, and both should have visible ownership when a cluster is upgraded or a workload moves. COMMERCIAL CONSIDERATIONS Confirm the quote against runtime, scanning, posture, deployment model, and support requirements. Installation documentation establishes technical components, but does not provide a complete current commercial package. - Protected hosts, Kubernetes nodes, and selected modules in the quote - Required collection components and their operating resources - Retention, deployment support, upgrades, and policy engineering EVALUATION PLAN / PROPOSED TESTS, NOT COMPLETED RESULTS 1. Prove complete node coverage Acceptance evidence: Compare the cluster node inventory with component health; include a deliberately unscheduled or unsupported test node. Owner: __________ Pass criterion: __________ Observed result: __________ Evidence location: __________ 2. Separate detection from prevention Acceptance evidence: Run paired benign policy fixtures in observe and enforce modes; preserve actual process outcomes and the relevant settings. Owner: __________ Pass criterion: __________ Observed result: __________ Evidence location: __________ 3. Reproduce a runtime-informed fix Acceptance evidence: Trace a finding to the image and workload, deploy a corrected image, and show both scan and runtime evidence after rollout. Owner: __________ Pass criterion: __________ Observed result: __________ Evidence location: __________ QUESTIONS FOR THE VENDOR - Which kernels, node types and managed Kubernetes modes support the sensor? - How does the team distinguish unobserved activity from proof that a package is never used? - What operational overhead and alert-review work appear in the team’s own bounded lab? EVIDENCE GAPS - No independent kernel compatibility, sensor-overhead, false-positive, or prevention benchmark was conducted. - Final licensing, current supported versions, and any self-managed control-plane requirements must be checked for the proposed environment.
