OT xCompliance & Regulatory Readiness
Summary: Dragos describes a distinction between frameworks, which are detailed guidelines for implementing controls such as NIST CSF, ISA/IEC 62443 and C2M2 and carry no enforcement power unless written into contracts, and regulations, which are legal requirements enforced by government bodies including US NERC CIP and TSA rules, EU NIS2, UK CAF and Australian SOCI. The text puts comprehensive OT compliance implementation costs at $500K to $5M+, with monitoring platforms at $100K-500K annually, infrastructure upgrades at $200K-2M, specialized personnel at $150K-300K per FTE and ongoing services at $50K-200K annually, and says basic compliance takes 12-18 months while comprehensive programs take 18-36 months.
Key Takeaway: NERC CIP penalties run $100K-10M+ and EU NIS2 fines reach 2% of global revenue, so the gap between treating a framework as optional and a regulation as binding carries a direct financial cost. The same text notes limited visibility into OT assets and difficulty patching legacy systems as common challenges, which means the asset inventory that compliance depends on is often the thing organizations cannot produce.
