Cyber Security Assessment

Focused on the Identify and Protect elements of the NIST Cyber Security Framework


Nexor consultants use a wide range of security assessment tools and techniques to determine a view of the cyber security posture of an organisation. An organisation’s posture includes both the threats it faces and its ability to respond to them. Leading on from the assessment we can provide mitigation advice and develop security improvement plans.

Examples of our security assessments

We will tailor our security assessment to the specific needs of the organisation. Examples include:

  • A secure information exchange requirements study (see an example here), to establish the security needs of a cross domain solution
  • A standards based risk assessment, using a framework such as ISO 27005, to provide an assessment of a specific business process or secure information exchange challenge. The approach combines a threat assessment with vulnerability assessments to identify and prioritise risk
  • A gap analysis against an existing standard, such as Cyber Essentials, NCSC 10 Steps to Cyber Security, NIST Framework, or the NCSC Cyber Assessment Framework.

Benefits of a Nexor security assessment

A Nexor cyber security assessment has two primary benefits. The first is confidence that the full suite of risks facing your business has been considered in a structured assessment. This is important for client and stakeholder confidence, as well as compliance requirements.

The second benefit is more practical. A full security assessment can identify areas in which your organisation needs to improve. Your organisation can then take steps towards those improvements itself or you can continue to work with Nexor to implement security solutions. Our CyberShield Secure® methodology means that we will ensure that any solutions we implement meet both your business and security goals.

Security assessment FAQs

If you’re still uncertain as to whether or not your organisation would benefit from a security assessment, read our answers to commonly asked questions to find out more.

What is a cyber security risk assessment?

According to ISO 27001 – an internationally recognised cyber security standard – a cyber security security risk assessment is the “overall process of risk identification, risk analysis and risk evaluation,”

What is the purpose of a security risk assessment?

Every organisation faces threats to its security that have the potential to keep it from meeting successful business outcomes. A full cyber security risk assessment will give you the confidence that the full suite of risks that your business faces has been considered and could help your organisation take steps to mitigate them.

How do you carry out security assessments?

Any effective risk assessment requires the experience and expertise to choose an appropriate baseline for assessment. The baseline is usually one of a set of widely recognised industry standards, including Cyber Essentials, NCSC’s 10 Steps to Cyber Security, NIST Cyber Security Framework, NCSC’s Cyber Assessment Framework and ISO 27001.

A suitable assessment methodology then needs to be chosen alongside the framework. For example, you may choose to carry out a gap assessment against the baseline, looking for areas in which your organisation needs to improve. Alternatively, you might use an existing methodology, like the ISO 27005 methodology, to carry out a risk assessment.

Nexor’s security consultants have years of experience that enable them to choose the correct framework and methodology for a security assessment. Get in touch with us to find out more about how we can help.
