Cyber Risk Profile (CRP): A Clear Guide for UK Organisations 

A Cyber Risk Profile, commonly referred to as CRP, is a core concept in UK defence cyber security and supplier assurance.  

It’s used to assess the level of cyber risk associated with a contract, service or system, and determines the cyber security controls an organisation is expected to implement.  

Despite its importance, CRP is often referenced without explanation, leaving many organisations unclear about what it means for them, and why it matters. This lack of clarity can create real challenges.  

CRP is increasingly referenced in tender documents, supplier questionnaires and contractual requirements, particularly where organisations work with the Ministry of Defence (MoD) or defence supply chains. Understanding your CRP is essential for managing risk, meeting compliance obligations, and avoiding costly delays during assurance or certification. 

In this guide, we’ll provide a clear, practical understanding of what a Cyber Risk Profile (CRP) is, how it fits within the Cyber Security Model (CSM), how CRP levels are defined, and why it directly influences Defence Cyber Certification (DCC) requirements. Gain the knowledge you need to interpret CRP expectations confidently and understand what’s required to meet them. 

Key Takeaways 

• A Cyber Risk Profile (CRP) defines the level of cyber risk associated with a contract or service, not the size of your organisation. 
• CRP sits at the heart of the Cyber Security Model (CSM) and determines the controls you are expected to implement. 
• There are four CRP levels, from Level 0 to Level 3, with increasing assurance and evidence requirements. 
• CRP directly influences the scope and level of Defence Cyber Certification (DCC) required for defence suppliers. 
• Understanding your CRP early helps to avoid compliance gaps, tender delays, and any assurance failures. 

What is a Cyber Risk Profile (CRP)? 

A Cyber Risk Profile (CRP) defines the level of cyber risk associated with a contract or service, and determines the cyber security controls an organisation must implement.  

It’s a core concept within the UK defence Cyber Security Model (CSM) and directly influences assurance and defence cyber securtity requirements. 

Cyber Risk Profile definition (plain English) 

A Cyber Risk Profile is a risk-based classification used to determine how much cyber security assurance is required for a specific contract, system or service. It reflects the potential impact that a cyber incident could have on defence operations, sensitive information, or national security. 

CRP exists to ensure that cyber security controls are proportionate to risk. Rather than applying the same requirements to every organisation, the CRP approach scales expectations based on what you do, the data you handle, and the systems you access. 

CRP applies to organisations that deliver goods or services connected to defence, including prime contractors, subcontractors and suppliers across the defence supply chain. It’s not limited to large organisations and can apply to businesses of any size. 

Why Cyber Risk Profile is important for UK organisations 

Cyber Risk Profile underpins risk-based compliance in the UK defence sector. It ensures that security controls are aligned with real-world risk rather than arbitrary checklists. 

CRP also plays a critical role in contractual and supplier obligations. It’s increasingly referenced in tender documentation and supplier assurance processes, meaning that organisations in scope are expected to fully understand and meet CRP-related requirements. 

CRP isn’t just another framework. It’s a decision-making mechanism that directly influences assurance expectations, certification pathways, and the evidence you must provide to demonstrate cyber resilience. 

Why Do Organisations Need a Cyber Risk Profile? 

Organisations need a Cyber Risk Profile to understand the level of cyber risk their contracts present, and the security controls they are expected to implement.  

CRP ensures that cyber security requirements are proportionate, defensible, and aligned to contractual, regulatory and business risk. 

CRP and business risk 

Cyber Risk Profile is about business risk as much as it is about cyber security. A cyber incident can disrupt operations, damage reputation, and lead to contractual penalties or loss of future work. 

CRP affects senior leadership decisions because it influences investment priorities, risk appetite, and assurance planning.  

Boards and executives are increasingly expected to understand how cyber risk aligns with contractual and regulatory obligations, particularly under frameworks such as DORA, NIS2 and the CRA. 

When Cyber Risk Profile becomes mandatory 

CRP becomes mandatory when organisations engage in defence contracts, where cyber security risk must be assessed formally. This includes direct contracts with the Ministry of Defence and many defence related supply chain arrangements. 

Supply chain assurance is another trigger. Organisations may be required to demonstrate their CRP alignment to reassure customers and partners that cyber risks are being managed appropriately. 

CRP may also apply in regulated environments where defence-related data, systems or services are involved, even if defence is not your primary business focus. 

How Cyber Risk Profile Fits Within the Cyber Security Model (CSM) 

Cyber Risk Profile sits at the core of the Cyber Security Model and determines how cyber risk is assessed and managed for defence-related contracts.  

The CSM uses CRP to ensure cyber security controls are proportionate to the sensitivity of data, systems and operational impact involved. 

What is the Cyber Security Model? 

The Cyber Security Model (CSM) is the framework used by the UK Ministry of Defence to assess cyber risk and determine appropriate security controls for defence suppliers. 

The MoD uses a risk-based model to ensure that security expectations are proportionate, and focused on protecting what matters most. This approach avoids overburdening low risk suppliers, while ensuring that high risk activities receive appropriate scrutiny. 

How CRP is determined under the Cyber Security Model 

CRP is determined based on several inputs, including the sensitivity of information handled, the systems accessed, and the potential impact of compromise. 

Data sensitivity plays a major role, particularly where classified or operationally sensitive information is involved. System access is also critical, especially where suppliers connect to defence networks or environments. 

CRP as the foundation of CSM assurance 

CRP forms the foundation of all assurance activities within the Cyber Security Model. Once the CRP is set, it dictates which controls apply and how assurance should be carried out. 

A common misconception is that CRP reflects organisational maturity. In reality, it reflects contractual and operational risk.  

Even mature organisations can be assigned a high CRP if the UK defence context demands it. 

Understanding Cyber Risk Profile Levels (CRP Levels 0–3) 

Cyber Risk Profile levels define the degree of cyber risk associated with a contract, ranging from minimal risk at Level 0 to the highest risk at Level 3.  

Each CRP level sets clear expectations for the depth of controls, assurance and evidence required. 

Overview of Cyber Risk Profile levels 

There are four CRP levels, ranging from Level 0 to Level 3. Each level represents increasing cyber risk and corresponding control requirements. 

CRP Level 0 – Basic risk 

CRP Level 0 applies where cyber risk is minimal. Typical scenarios include contracts with no access to sensitive information or systems. 

Example use cases include low risk services with no data handling or connectivity to defence environments. 

CRP Level 1 – Foundational risk 

CRP Level 1 reflects low to moderate risk. Organisations at this level may handle limited sensitive information, or provide supporting services. 

Common organisations at this level include suppliers with basic system access, or limited data exposure. 

CRP Level 2 – Advanced risk 

CRP Level 2 introduces higher risk and stronger control requirements. Organisations may access sensitive systems or handle information that could cause operational impact if compromised. 

UK defence cyber compliance challenges often arise at this level, due to increased governance, technical and evidence expectations. 

CRP Level 3 – Expert risk 

CRP Level 3 represents the highest risk. It applies to organisations whose compromise could have serious consequences for defence capability or national security. 

At this level, evidence and governance matter most. Assurance expectations are rigorous and ongoing. 

What Controls Are Required for Each Cyber Risk Profile? 

The controls required for each Cyber Risk Profile are defined by Def Stan 05-138 and increase in scope and rigour as cyber risk rises.  

Higher CRP levels require stronger governance, technical safeguards, and operational assurance to manage defence related risk effectively. 

How Def Stan 05-138 underpins CRP requirements 

Def Stan 05-138 defines the cyber security controls required for defence suppliers and maps them to CRP levels. 

The relationship between CRP and controls is direct. Higher CRP levels require more comprehensive and robust controls. 

Def Stan 05-138 is referenced in contracts because it provides a consistent and enforceable standard for cyber security assurance. 

Control expectations increase with CRP level 

Governance requirements increase as CRP levels rise, including risk management, policy ownership and accountability. 

Technical controls become more advanced, covering areas such as access control, security monitoring, and incident response. 

People and process controls also scale, including training, role definition and operational procedures. 

Common gaps organisations face against CRP controls 

Documentation often doesn’t reflect reality, creating gaps during assessments. Over reliance on tooling without supporting processes is another common issue. 

Lack of ownership can undermine even well designed control frameworks. 

How Cyber Risk Profile Links to Defence Cyber Certification (DCC) 

Cyber Risk Profile determines the level of assurance required under Defence Cyber Certification and directly influences the certification pathway an organisation must follow. Understanding CRP is essential to selecting the correct DCC level and avoiding misaligned or unnecessary certification effort. 

CRP as the starting point for Defence Cyber Certification 

CRP determines the level of assurance required under DCC and sets the baseline for what certification activities are needed. 

Without understanding CRP, organisations risk pursuing the wrong certification level or scope. 

CRP and DCC alignment explained 

CRP maps directly to certification effort, influencing cost, timescales, and evidence requirements. 

Pursuing the wrong level of certification can cause delays, rework, and assurance failure. This is why CRP clarity is essential before you start implementing Defence Cyber Certification. 

What Cyber Risk Profile Means for Your Organisation 

Cyber Risk Profile defines what your organisation is accountable for in terms of cyber security controls, assurance and evidence. It directly affects how you approach tenders, contracts and ongoing supplier assurance activities. 

Impact on tenders, contracts and supplier assurance 

Buyers expect suppliers to understand their CRP obligations and demonstrate appropriate controls. 

Assessors look for alignment between stated controls and real-world implementation, not just documentation. 

What CISOs, IT Directors and Compliance Officers are accountable for 

Governance structures must support CRP requirements and evidence must be accurate, current, and defensible. 

Continuous assurance is increasingly expected, rather than one-off compliance activity. 

How to Prepare for Cyber Risk Profile Assessment 

Preparing for a Cyber Risk Profile assessment means understanding your risk context, aligning your controls to real world operations, and ensuring that evidence is accurate and defensible. Early preparation reduces assurance gaps and avoids delays during assessment or certification. 

Key questions to ask before your CRP is assessed 

• Are responsibilities for cyber risk clearly defined and owned? 
• Do your controls reflect how systems and data are actually used? 

Evidence, documentation and operational maturity 

Good evidence demonstrates consistent implementation, not just intent. Policies alone are not enough without supporting processes and operational proof. 

Common Cyber Risk Profile Mistakes (and How to Avoid Them) 

Many organisations struggle with Cyber Risk Profile because they misunderstand its purpose or treat it as a compliance checkbox. Avoiding common CRP mistakes helps to ensure proportionate security, smoother assurance, and stronger outcomes. 

Treating CRP as a tick-box exercise 

CRP requires risk understanding, not checklist compliance. 

Assuming existing certifications automatically meet CRP 

Certifications do not always align with CRP control requirements. 

Underestimating ongoing compliance effort 

CRP expectations evolve as contracts and risk change.
