What is the NIS Regulations?

Since May 2018, essential services providers have been subject to the Network and Information Systems Regulations 2018, also known as the NIS Regulations. The legislation affects two groups of companies:

• Operators of Essential Services (OES), such as energy, water, healthcare and transport.
• Relevant Digital Service Providers (RDSP), such as online marketplaces, cloud service providers and search engines.

There are 14 key principles for NIS compliance, split across four objectives. Your business must be able to manage security risk, protect against cyberattack, successfully detect cyber security events and minimise the impact of any cyber security incident.

Every UK Operator of Essential Services (OES) or Relevant Digital Service Provider (RDSP) must demonstrate NIS compliance.

Why do I need NIS Regulations compliance?


To meet legal obligations

Every OES or RDSP must pass a regular NIS audit, overseen by a Competent Authority (CA). If your business experiences a breach as a result of an NIS compliance failure, you may be fined up to £17 million.


To raise security standards

The NIS Regulations provides an opportunity to assess and upgrade your cyber security provisions. By implementing the Indicators of Good Practice (IGPs), your systems will meet industry best practice standards.


To better protect customers

Strengthening defences against breach will prevent sensitive data from being lost or stolen – and key national infrastructure being taken offline. A reliable, secure service is crucial to building a loyal customer base.


To increase business resilience

The NIS Regulations takes a holistic approach to IT security, assessing resilience of service as well as defences against cyberattack. Meeting the NIS objectives will help you build systems capable of delivering services during and after an IT security event.

Our Approach

Audit preparation assessment

With our in-depth knowledge of the NIS Regulations and its requirements, our consultants can conduct a pre-audit assessment. This will help you identify areas that require improvement before an official audit is performed.

Penetration testing

We will perform extensive penetration tests to help you understand the effectiveness of current security systems. Using the same tools and techniques as cybercriminals, we can accurately emulate a cyber security event – and your preparedness to deal with it.

Incident response planning

Cyber security events are inevitable for every OES and RDSP – but do you have an NIS-compliant plan for dealing with them? Our consultants will review your incident response plans and identify potential improvements.

Implementation assistance

More than simply providing a list of required improvements, Fidus consultants are on hand to implement them too. Working alongside your IT security team, we can ensure you have the right measures in place to pass your next NIS Regulations assessment.
