Cyber Assessment Framework 4.0

By Nathan Smallshaw·November 19, 2025
Cyber Assessment Framework 4.0

Overview

The UK's Cyber Assessment Framework (CAF) 4.0 offers organisations a methodical pathway for evaluating and strengthening cyber resilience across four key dimensions: governance, protection, detection, and response.

Why Adopt CAF 4.0 Now?

Organisations should implement CAF 4.0 ahead of upcoming regulatory changes, particularly the government's planned Cyber Security and Resilience Bill. Early adoption enables companies to:

  • Identify and address resilience vulnerabilities
  • Demonstrate forward-thinking governance practices
  • Foster a continuous improvement culture

Alignment with Future Legislation

CAF 4.0 correlates with anticipated legislation requirements including:

  • Stricter incident reporting obligations
  • Supply-chain security assurance
  • Secure software development practices

Republic's Role

Recyber's Republic platform operationalises CAF 4.0 by delivering human-layer tools, analytics, and culture-building mechanisms needed to demonstrate maturity in cyber awareness, governance, and resilience. The platform specifically addresses the framework's Cyber Culture and Cyber Awareness Guidelines.

Republic bridges policy implementation with practical execution, enabling organisations to evidence CAF alignment while enhancing employee cyber behaviours.

Organisations interested in implementing CAF 4.0 can schedule demos or initiate free trials through Recyber's getting-started portal.
