Forescout Device Compliance vs Knocknoc: Side-by-Side Comparison (2026)

Forescout Device Compliance

Mid-market and enterprise security teams struggling with unmanaged IoT, medical, and OT devices will get the most from Forescout Device Compliance because its agentless discovery actually finds what you don't know exists, then enforces policy without requiring endpoint agents. The platform classifies devices across 150+ attributes and monitors 250+ protocols, which means you catch shadow devices in clinical networks or manufacturing floors before they become breach vectors. Skip this if your environment is Windows-dominant and agent-heavy; Forescout prioritizes continuous asset visibility and compliance monitoring over incident response, so it pairs better with separate detection and investigation tools than replacing them.

Knocknoc

SMB and mid-market teams managing fragmented network access controls will find Knocknoc's identity-first allowlisting approach faster to deploy than rip-and-replace zero trust platforms. It orchestrates your existing firewall and network gear through SSO authentication rather than forcing new infrastructure, which cuts implementation friction when you're resource-constrained. The hybrid deployment model and scripting backend let you protect both internal subnets and OT networks without separate tools. Skip this if you need endpoint detection or behavioral analytics layered on top; Knocknoc is network perimeter hardening, not a full access control suite.
