NCSC CAF v4 guided report tour

See how mapped responses become CAF-specific review direction

Explore how Aegis101 retains the framework's objectives, principles, contributing outcomes and IGP direction while keeping confirmed and outstanding answer populations, interim status, evidence needs, follow-up routes and the judgement boundary visible.

Fictional, sanitised product example. This is an answer-based NCSC CAF v4 mapped screening view, not a formal CAF assessment or assigned achievement judgement.

Framework-native reporting

Recognisable CAF structure, traceable assessment direction

Aegis101 uses the CAF hierarchy to organise screening signals and follow-up without translating the framework into generic Core risk labels. Users can see what contributed to the view and what still requires evidence, applicability review or competent judgement.

Framework hierarchy

The report retains the CAF outcome structure

Framework confidence starts with recognisable organisation. Aegis101 groups the 41 contributing outcomes beneath the correct principles and objectives rather than flattening them into a generic control list.

Objective A · 4 principles

Managing security risk

A1 Governance · A2 Risk Management · A3 Asset Management · A4 Supply Chain

Objective B · 6 principles

Protecting against cyber attacks

B1 Service protection policies, processes and procedures · B2 Identity and Access Control · B3 Data security · B4 System security · B5 Resilient networks and systems · B6 Staff awareness and training

Objective C · 2 principles

Detecting cyber security events

C1 Security Monitoring · C2 Threat Hunting

Objective D · 2 principles

Minimising the impact of cyber security incidents

D1 Response and recovery planning · D2 Lessons Learned

Outcome overview

Coverage and outstanding status are shown without being mistaken for achievement

The overview separates outcomes with a usable mapped answer basis from gaps, partial indications and insufficient information. Unresolved mapped controls remain Not Assessed in an interim view and provide a direct completion route; they do not become a favourable CAF position.

CAF outcome distributionThe visual uses CAF-specific follow-up populations and a separate mapped-answer denominator. The figures are illustrative and do not represent an evidence-validated CAF judgement.
03

Mapped answer basis

Trace each indication back to what shaped it

A framework view earns confidence when users can understand the route from recorded answers to the outcome requiring review.

Recorded responseAnswer and declared context

The submitted basis remains visible and uncertainty is retained.

Governed mappingRelevant CAF outcome

The response contributes only where a reviewed mapping exists.

Screening indicationDirection, not judgement

The result identifies a concern, partial signal or insufficient basis.

Follow-upEvidence and decision route

The report identifies what should be reviewed next.

Illustrative contributing outcome

A1.a Board Direction

Objective A · Principle A1 Governance

Screening indication
Gap indicated from the mapped answer basis.
Mapped concern
Senior ownership, accountability and reporting for the essential function are not sufficiently evidenced.
Evidence direction
Review board-level direction, accountable ownership, governance reporting, decision records and escalation routes.
Judgement boundary
Confirm scope, applicability, IGP interpretation and evidence before assigning any CAF outcome judgement.
Contributing-outcome traceabilityThe report retains the recorded answer basis beside the mapped concern and evidence direction, so the screening indication can be challenged without being mistaken for a formal CAF judgement.
04

Indicators of Good Practice

Use CAF reference language without claiming the outcome

Relevant IGP direction helps users understand the characteristics to examine. A mapped direction highlights the reference column requiring attention; it is not an Aegis101 declaration that the contributing outcome has been achieved, partially achieved or not achieved.

In this illustrative A1.a example, the mapped answer basis is reviewed against the native Not Achieved and Achieved reference characteristics. Aegis101 does not add a Partially Achieved state where the CAF v4 outcome does not define one.

Not Achieved

Reference characteristics indicating that the expected governance outcome is materially absent or ineffective.

Achieved

Reference characteristics describing the expected outcome operating with clear ownership, direction and review.

Important: CAF v4 reference states are outcome-specific. This A1.a example has no native Partially Achieved IGP column. IGPs support informed assessment but do not remove the need for cyber-security expertise, sector knowledge, evidence review and consideration of special circumstances.
Principle and IGP reference viewThe mapped response direction remains separate from the native outcome-specific IGP states used for competent review.
05

CAF-specific follow-up

Turn contributing outcomes into governed next steps

The CAF action plan does not reuse Core severity swim lanes. It groups contributing outcomes by the type of framework work required.

Treatment and control improvement

Address mapped weaknesses, assign ownership and connect remediation to the affected contributing outcomes.

Evidence and judgement review

Gather evidence, assess relevant IGPs and record the competent judgement supporting the outcome position.

Applicability and exception decision

Record why an outcome or indicator is not applicable and how compensating measures or accepted exceptions are governed.

Sustain and reassess

Retain evidence, monitor the operating position and refresh the mapped view after material change or treatment.

CAF contributing-outcome action planFramework follow-up remains separate from Core severity lanes and connects each contributing outcome to the evidence, judgement, or treatment route it requires.
06

Evidence and confidence

Show what is known, what is missing and what requires judgement

The framework view keeps response completeness, mapped coverage, evidence validation, target-profile context and formal outcome judgement separate.

Assessment boundary

Define the essential function, supporting systems, dependencies and organisational scope before relying on the mapped view.

Evidence status

Identify whether policies, records, tests, monitoring outputs and other artefacts have been reviewed or remain unvalidated.

Target profile

Show whether a target profile has been supplied; do not infer the appropriate target for an organisation or sector.

Version, reassessment, and comparison

Retain CAF version context and assessment history. Authorised users can rerun eligible assessments after change and compare only compatible governed framework bases they can access.

CAF basis and boundaryMissing scope, dependency, target-profile, or evidence information is retained as a limitation. It cannot silently create a favourable screening position.
Assurance boundary

Aegis101 provides an NCSC CAF v4 mapped screening view and direction for further review. It does not provide an NCSC-approved assessment, regulatory decision, audit, certification, evidence validation or assigned CAF achievement judgement.
