CST VerdictShort answer
Platform teams running Kubernetes on-premises or in hybrid clouds will get the most from Cilium because its eBPF kernel-level enforcement eliminates the latency and blind spots of traditional overlay networking. With 23,959 GitHub stars and active deployments at scale across financial services and public sector organizations, Cilium's approach to policy enforcement at the dataplane level is proven; it also handles observability without requiring sidecar injection, which keeps resource overhead predictable. Not the right fit for teams needing a managed SaaS experience or those prioritizing CSPM and infrastructure compliance scanning over network microsegmentation. Mid-market and enterprise teams managing mixed device fleets, including BYOD, should pick Cisco Duo Device Trust for its agentless verification that actually works without forcing endpoint agents into your stack. The tool covers continuous device trust across managed, unmanaged, and personal devices with real-time health checks, and its adaptive policy enforcement addresses NIST PR.AA and PR.PS without adding deployment friction. Skip this if you need deep endpoint detection and response capabilities; Duo Trust stops non-compliant devices at the gate but doesn't hunt threats already inside your network.
