Expert Guidance to Achieve, Evidence and Maintain NCSC CAF Compliance
The NCSC Cyber Assessment Framework is the UK government’s benchmark for cyber resilience across critical national infrastructure, essential services, and regulated sectors. If your organisation is in scope — whether as an Operator of Essential Services, a managed service provider, or a public sector body — CAF isn’t optional guidance. It’s the standard your regulators use to assess whether your cyber security and resilience is genuinely adequate.
DigitalXRAID’s NCSC CAF consultancy gives you the expert, outcome-focused support to understand your current position, close your gaps against the framework, and demonstrate evidence-based compliance to your Competent Authority.
What is the NCSC Cyber Assessment Framework?
The NCSC CAF is an outcomes-based framework developed by the National Cyber Security Centre to help organisations assess and improve their cyber resilience. It's built around four objectives, 14 principles, and 41 contributing outcomes. Assessment uses Indicators of Good Practice (IGPs) and requires expert judgement — it's not a tick-box exercise.
The Four CAF Objectives
- Objective A: Managing Security Risk — governance, risk management, asset management, and supply chain
- Objective B: Protecting Against Cyber Attack — service protection policies, identity and access control, data security, system security, resilient networks, and staff awareness
- Objective C: Detecting Cyber Security Events — security monitoring and threat hunting
- Objective D: Minimising the Impact of Cyber Security Incidents — response and recovery planning, and lessons learned
The current version, CAF v4.0, was published in August 2025 and introduces stronger requirements around threat understanding, proactive threat hunting, secure software development, and AI-related cyber risks. CAF is now used by nearly all UK cyber regulators and is the established baseline for public sector assurance through GovAssure.

What Organisations Achieve Through CAF Alignment
For Operators of Essential Services and organisations in regulated sectors, CAF compliance is a legal obligation under the NIS Regulations. The Cyber Security and Resilience Bill will extend these obligations significantly, placing CAF on a statutory footing for MSPs, data centres, and designated critical suppliers.
- Demonstrate cyber resilience clearly to their sector regulator and Competent Authority
- Build a credible, evidence-based case for cyber security investment at board level
- Reduce the risk of regulatory intervention or enforcement action
- Identify and close material gaps in their security posture across IT, OT, and supply chains
- Maintain and continuously improve their CAF maturity profile over time

How DigitalXRAID Delivers CAF NCSC Compliance
Our service is structured around the framework’s four objectives. We work as an extension of your team, helping you understand your current maturity, build the evidence your regulator needs to see, and implement the improvements that will make the most difference.
We build the governance foundations your CAF compliance depends on: cyber governance policies, risk management processes, asset management across IT and OT, and supply chain risk controls including third-party obligations strengthened under CAF v4.0.
We implement and evidence the protective security measures your regulator expects: service protection policies, identity and access controls, data security, system security across IT and OT, resilient network architecture, and sector-specific staff awareness programmes.
CAF v4.0 raises the bar for detection maturity significantly. DigitalXRAID’s 24/7 CREST-accredited Managed SOC delivers continuous monitoring with behavioural baseline analysis, structured intelligence-led threat hunting, and documented detection processes that provide credible evidence for your Competent Authority.
Our NCSC CIR Level 2 Assured Service Provider status means we deliver Objective D with operational credibility, not just advisory guidance. This covers tailored incident response plans and playbooks, proactive tabletop exercises, rapid 24/7 incident response, and structured post-incident review.

Expert Judgement, Not Box-Ticking
The NCSC is explicit that CAF requires expert judgement. Our consultants understand what good looks like in your sector — and what your Competent Authority expects to see — so the evidence we build reflects genuine security maturity.

CAF isn’t a point-in-time exercise. We work with you from initial assessment through gap remediation, evidence development, regulatory engagement, and ongoing maturity improvement as the framework and threat landscape evolve.
Frequently Asked Questions
The NCSC CAF is an outcomes-based framework developed by the National Cyber Security Centre to help organisations assess and improve their cyber resilience. It’s built around four objectives, 14 principles, and 41 contributing outcomes, and is used by nearly all UK cyber regulators as the standard for assessing the cyber security of organisations delivering essential services and critical national infrastructure. The current version is CAF v4.0, published in August 2025.
CAF applies primarily to Operators of Essential Services under the NIS Regulations, Relevant Digital Service Providers, and public sector organisations subject to GovAssure or equivalent oversight. The Cyber Security and Resilience Bill will extend these obligations to managed service providers, data centres, and designated critical suppliers. If your sector regulator or Competent Authority references CAF as part of their oversight regime, it applies to you.
A CAF profile defines the target level of cyber security and resilience your organisation needs to achieve, based on your sector and threat context. Profiles are set by Competent Authorities, not the NCSC directly, and vary by sector. The two main profile types are Basic (covering defences against common, financially motivated attacks) and Enhanced (for higher-risk organisations facing more sophisticated threats). Achieving your CAF profile means demonstrating that the required contributing outcomes have been met.
ISO 27001 is an international information security management standard with prescriptive controls and a certifiable audit process. NCSC CAF is a UK-specific, outcomes-based framework assessing your cyber resilience against your sector’s threat profile. Both are valuable and have significant overlap, but CAF adds specific obligations around regulatory engagement, reporting timelines, operational technology, and sector-specific threat modelling that ISO 27001 alone doesn’t address.
IGPs are the detailed criteria used to assess whether each of CAF’s 41 contributing outcomes has been achieved, partially achieved, or not achieved. They’re designed to guide expert judgement, not replace it. Having IGPs in place doesn’t mean an outcome is automatically achieved — your assessor will consider your specific circumstances, the sector context, and the quality of evidence you provide.
The timeline depends on your organisation’s size, complexity, existing security maturity, and the number of systems or services in scope. An initial assessment and gap analysis for a mid-sized organisation typically takes four to eight weeks. Evidence development and remediation work is ongoing, often running across a 12 to 24-month programme. DigitalXRAID works with your team to set realistic timelines aligned to your regulatory obligations.
The Cyber Security and Resilience Bill, currently progressing through Parliament, will place NCSC CAF on a firmer statutory footing as the compliance baseline for in-scope organisations. It extends the scope of mandatory cyber obligations to managed service providers, data centres, and designated critical suppliers, with incident reporting timelines of 24 hours for initial notification and 72 hours for a full report. If your organisation will be in scope, CAF v4.0 alignment is the foundation from which all other compliance activity should be built.
