Purdue Model Implementation Guide for OT Cybersecurity The Purdue Enterprise Reference Architecture (PERA), or Purdue Model, provides a hierarchical framework for segmenting Industrial Control Systems (ICS) and Operational Technology (OT) networks. It ensures secure IT/OT convergence while protecting critical processes from cyber threats. Widely adopted in standards like ISA/IEC 62443, NIST SP 800-82, and Cisco/Rockwell’s

Implementing an IDMZ is a critical investment in OT cybersecurity, particularly for metals/mining operations amid rising threats (e.g., ransomware incidents like Norsk Hydro’s $70M impact). Costs vary widely based on site size (single facility vs. multi-site), complexity (legacy systems, number of data flows), vendor (e.g., Palo Alto, Cisco/Rockwell), and scope (basic macro-segmentation vs. advanced with
