A recent survey indicates that 80% of critical national infrastructure (CNI) providers in the UK face downtime costs ranging from £100,000 to £5 million due to cyber-attacks targeting operational technology (OT). The survey, conducted by e2e-assure, highlights that 23% of OT downtime incidents cost over £1 million, with 6% exceeding £5 million. This growing concern is fueled by fears of nation-state attacks, particularly in light of recent geopolitical tensions. The report also notes that many organizations struggle to detect breaches promptly, with 10% of large enterprises taking over a year to remediate incidents. Additionally, reputational damage and supply chain compromises are significant risks, with 21% of mid-sized organizations reporting multiple incidents linked to third parties. The economic impact of these breaches is substantial, with unplanned downtime costing industrial manufacturers up to $50 billion annually. The shift in threat landscape emphasizes the need for improved visibility and proactive measures in OT environments.
