Network and Information Systems Regulations (NIS Regulations)

On 10 May 2018 the EU Network and Information Systems (NIS) Directive became law in the UK as the Network and Information Systems Regulations 2018. They mandate that the ‘Operators of Essential Services (OES)’ who provide electricity, oil, gas, water, healthcare and transport take appropriate and proportionate security measures to manage risks to their network and information systems and notify serious incidents to the relevant Competent Authority.

UK Competent Authorities are taking a proactive approach by implementing an assessment framework including an audit programme to encourage their respective OES to prevent incidents happening.
As an NCSC Certified Cyber Security Consultancy (CCSC) for Risk Assessment and Risk Management, Arcanum are an approved source of help and advice.

The National Cyber Security Centre trusts Arcanum.
So can you.


“A requirement came up on a project we were working on for a Higher Education client, for a security specialist to advise on all aspects of physical and digital security for the new development. Arcanum filled that need, with a professional, thorough, knowledgeable and friendly attitude. Whether working with the client to help them understand their needs, or working with the design team to translate these into solutions, the Arcanum team were pivotal in the success of this project. We would not hesitate to work with or recommend this team as we know we would be in safe hands.”
