Meeting the Digital and Compliance Needs of UK OESs
As part of its drive to optimise the quality and availability of critical services across the UK, the Government is boosting investment in Critical National Infrastructure’s ongoing. As a result, Operators of Essential Services (OESs) must consider a range of increasingly complex challenges:
The ongoing need to maintain legacy systems limits the convergence of IT and OT.
Making intelligent digital investments that drive real-time visibility of diverse infrastructure.
Adopting a ‘defence-in-depth’ approach to security in a turbulent geopolitical landscape.
Evolving compliance obligations, including the IEC-62443 standard, the Cyber Security and Resilience Bill, the NCSC NIS 2018 directive, and CAF V4.
The Exponential-e Group is actively supporting this journey, working closely with OESs to overcome their unique digital challenges and streamline their compliance obligations. We achieve this by combining more than twenty years of sector-specific experience and broad technical capabilities across a growing range of managed services to design and deliver cyber-secured platforms, networks, infrastructure, managed services, and 24 / 7 support in the most complex environments - with our own enterprise-class network underpinning everything.
