Cyber Assessment Framework (CAF)

Protect your critical infrastructure with comprehensive cybersecurity assessment

Why Your Organization Needs the Cyber Assessment Framework

In today's interconnected world, your organization faces unprecedented cyber threats that can disrupt operations, compromise sensitive data, and damage your reputation. For operators of essential services and critical national infrastructure, these risks are magnified by regulatory requirements and the potential for widespread impact.

The Cyber Assessment Framework (CAF) provides you with a structured approach to assessing and improving your cybersecurity posture, ensuring you not only meet regulatory obligations but build genuine resilience against evolving threats.

Understanding the CAF Framework

A structured approach to cybersecurity assessment

The Cyber Assessment Framework is organized into four key objectives, each containing multiple principles and contributing outcomes. This comprehensive structure ensures all aspects of your cybersecurity posture are thoroughly evaluated:

A Managing Security Risk

Governance, risk management, asset management, supply chain, and resilient networks and systems.

B Protecting Against Cyber Attack

Service protection policies, identity and access control, data security, system security, resilient networks, staff awareness and training.

C Detecting Cybersecurity Events

Security monitoring, proactive security event discovery, and security event analysis.

D Minimizing Impact of Incidents

Response and recovery planning, lessons learned, and vulnerability management.

Our CAF Assessment Process

A proven methodology for effective implementation

1

Initial Scoping

We work with you to define the scope of the assessment, identifying critical systems, key stakeholders, and specific regulatory requirements that apply to your organization.

2

Evidence Collection

Our experts gather comprehensive evidence through documentation review, interviews with key personnel, technical testing, and observation of security practices.

3

Assessment Against CAF

We evaluate your current security posture against all applicable CAF outcomes, determining achievement levels for each indicator and identifying specific gaps.

4

Gap Analysis

We analyze identified gaps, prioritizing them based on risk level, regulatory importance, and potential business impact to create a focused remediation strategy.

5

Improvement Planning

We develop a detailed improvement roadmap with specific recommendations, timelines, resource requirements, and clear responsibilities for implementation.

6

Implementation Support

Our team provides expert guidance and hands-on assistance to help you implement the recommended improvements effectively and efficiently.

7

Reassessment & Reporting

We conduct follow-up assessments to verify improvements, measure progress, and provide comprehensive reporting for internal stakeholders and regulators.

CAF-Aligned Supplier Questionnaire Audits

Ensuring your supply chain meets the same high standards

Your security is only as strong as your weakest link. With increasing reliance on third-party suppliers, ensuring their cybersecurity practices meet your standards is essential. Our CAF-aligned supplier questionnaire audits help you:

  • Identify supply chain vulnerabilities before they impact your operations
  • Standardize security requirements across all vendors and partners
  • Demonstrate due diligence to regulators and stakeholders
  • Reduce the administrative burden of supplier security assessments
  • Create improvement plans for critical suppliers

Current Pain Points We Solve:

Inconsistent Assessment Approaches

Replace ad-hoc supplier evaluations with a structured, consistent methodology based on CAF principles.

Questionnaire Fatigue

Reduce supplier frustration with our streamlined, focused questionnaires that capture essential information without unnecessary complexity.

Limited Verification

Move beyond self-attestation with our validation techniques that verify supplier claims through evidence review and targeted testing.

Regulatory Compliance Gaps

Ensure your supplier assessment process satisfies regulatory requirements for supply chain security oversight.

International Coverage

Our supplier questionnaire audits are tailored to meet requirements across multiple jurisdictions:

Frequently Asked Questions About CAF

Is my organization required to implement the Cyber Assessment Framework?

+

If your organization is designated as an Operator of Essential Services (OES) under the NIS Regulations or is part of the UK critical national infrastructure, you may be required to implement the CAF and demonstrate compliance to your competent authority. Even if not legally required, the CAF provides a valuable framework for assessing and improving your cybersecurity posture, particularly for organizations in critical sectors or those supporting essential services. Our team can help determine your specific regulatory obligations and how the CAF can benefit your organization.

How does the CAF relate to other frameworks like ISO 27001 or NIST CSF?

+

The CAF is complementary to other cybersecurity frameworks and standards. There is significant overlap between the CAF and frameworks like ISO 27001, NIST Cybersecurity Framework, and industry-specific standards. Organizations that have implemented these other frameworks will find many of their existing controls contribute to CAF compliance. We specialize in mapping between different frameworks to leverage existing security investments and avoid duplication of effort. Our approach identifies where your current security controls satisfy CAF requirements and where additional measures may be needed.

How long does a typical CAF assessment take?

+

The duration of a CAF assessment depends on several factors including your organization's size, complexity, and the scope of systems being assessed. Typically, a comprehensive CAF assessment for a medium-sized organization takes 4-8 weeks from initial scoping to delivery of the final report and improvement plan. This includes evidence collection, interviews, technical testing, analysis, and reporting. For larger organizations or those with particularly complex environments, the assessment may take longer. We work with you to develop a realistic timeline based on your specific circumstances and any regulatory deadlines you may be facing.

What evidence do we need to provide for a CAF assessment?

+

A comprehensive CAF assessment requires various types of evidence, including:

  • Documentation: Security policies, procedures, standards, and guidelines
  • Records: Risk assessments, audit reports, incident records, change management logs
  • Technical evidence: System configurations, network diagrams, vulnerability scan results
  • Process evidence: Observed security practices and procedures in action
  • Interview responses: Information from key personnel about security practices

We provide a detailed evidence request list at the beginning of the assessment and work with you to identify the most efficient ways to collect the required information while minimizing disruption to your operations.

How do we maintain CAF compliance over time?

+

Maintaining CAF compliance is an ongoing process that requires:

  • Regular reassessments: Typically annually or after significant changes to your environment
  • Continuous monitoring: Implementing tools and processes to continuously evaluate security controls
  • Change management: Assessing the security impact of system and organizational changes
  • Incident response: Learning from security events and incorporating lessons into your security program
  • Threat intelligence: Staying informed about evolving threats and adapting your controls accordingly

We offer ongoing CAF maintenance services to help you sustain compliance, including periodic reassessments, gap analysis, improvement planning, and support for regulatory reporting.
