Security of Network and Information Systems (NIS) Regulation

Security of Network and Information Systems (NIS) Regulation

Working with you to successfully navigate NIS Regulations compliance


In May 2018, after a long period of consultation with businesses, the UK and other EU nations adopted the EU Network and Information Systems Directive aimed at providing direction and governance for the companies that deliver essential services to defend against, and also report in a structured way about cyber-attacks. This has become UK Law (referred to as the NIS Regulations) and therefore encourages companies who provide infrastructure and essential services to:

  • Adopt the 14 high level security principles
  • Be aware of the penalty framework
  • Maintain an incident response framework including reporting to any relevant authorities anything that could be considered as a Breach and an Incident


There are two classes of organisations that the regulations have been designed for:

  • Operators of Essential Services (OES)
  • Digital Service Providers (DSP)

If your company provides any CNI such as, but not limited to, Energy (either upstream or downstream), Water, Financial services, transportation services or healthcare then the NIS Regulations apply to you. This is due to the fact that organisations such as these have been identified as extremely attractive targets for cyber (or a blended including cyber) attack.

The UK Government has confirmed that this adoption (and its subsequent requirements and recommendations) was not affected by the exit from the EU.


Article 14 of the Directive outlines 14 key security principles that come under four (4) high-level objectives. To assist organisations in self-assessing against this, the UK National Cyber Security Centre has released a cyber assessment framework (CAF) which allows them to determine level of compliance and provide evidence to the relevant Competent Authority (CA) to demonstrate that level.

The risks of non-compliance can be both reputational due to operational disruption (which may lead to other issues such a Class Actions from users affected by those disruptions) as well as financial (possible fines up to £17million).

Objective B6 – Staff Training and Awareness

One of the best ways to reduce the chance of these attacks being successful is to create a culture within the organisation that empowers staff to identify and report any suspicious activity. This, of course, only works if there is a good understanding of what ‘normal’ activity looks like!

It is recommended that staff attend regular awareness sessions to ensure they are kept up to date with policy changes, procedure updates, etc. These can either be via a computer-based training environment or delivered during face to face sessions. Additionally, the relevant training can be provided to those that need it as part of their role. We can help organisation with:

  • Designing and developing role-based skills and competency frameworks
  • GCT-accredited training courses
  • Skills gap analysis
