Whitepapers & Guides

Technical deep-dives on Zero Trust architecture, compliance frameworks, and industrial network security.

Practical guides and architecture references for security and compliance teams protecting industrial control systems, OT networks, and critical infrastructure. Each whitepaper covers real-world deployment patterns, covering Zero Trust access control, CMMC Level 2, NIS2, IEC-62443, and legacy OT equipment protection — without requiring network redesign or production downtime.

Beyond Purdue: Micro-DMZs for Modern OT

Why the Purdue Model and Industrial DMZ were never designed for today's OT — and how Micro-DMZs deliver Zero Trust without network redesign.
