Critical National Infrastructure operators face growing pressure to protect ageing operational systems from modern cyber threats while meeting evolving regulatory requirements. Fragmented OT and IT environments, limited specialist resources and increasing compliance obligations create significant operational and security risk.
Sword helps organisations protect and modernise the systems that underpin critical national services. Combining OT and IT expertise with 24/7/365 cyber defence and security-cleared specialists, we deliver secure, resilient and compliant operations.
From readiness assessments and compliance roadmaps to regulatory evidence packs and disaster recovery exercises, we help organisations reduce risk, demonstrate resilience and maintain operational confidence.
