🔒 Operational technology (OT) environments differ fundamentally from IT and demand a threat-informed approach to security that balances safety, uptime, and continuity. Traditional IT controls can disrupt industrial processes, so visibility, asset context, segmentation, and collaboration between IT and OT teams are essential. Fortinet recommends phased, visibility-first segmentation aligned with ISA/IEC 62443, OT-aware policies, passive discovery, and tailored protections such as virtual patching and secure remote access.

🛡️Fortinet has achieved IEC 62443-4-1 Maturity Level 2 (ML2) certification for its Secure Product Development Lifecycle (SPDL). This independent certification verifies that Fortinet’s secure development processes are formalized, documented, repeatable, and consistently applied across design, development, verification, validation, release, and maintenance of its security products. SPDL embeds threat modeling, secure-by-design engineering, automated and manual testing, supply chain integrity controls, and a transparent FortiGuard Labs PSIRT vulnerability disclosure process to improve product integrity for IT, OT, and critical infrastructure customers.

🔍 A study by OMICRON based on multi-year deployments of its StationGuard IDS across more than 100 substations, power plants, and control centers found pervasive cybersecurity and operational shortcomings. Passive network monitoring exposed unpatched PAC devices, undocumented external connections, weak segmentation, and incomplete asset inventories—issues often visible within 30 minutes of connection. The findings emphasize the need for protocol-aware, network-level detection and automated asset discovery to meet frameworks such as IEC 62443 and NIST.
