As cybersecurity regulations evolve across Europe, organizations are being asked to demonstrate not just compliance, but **structured, risk-based security maturity**. Under the EU’s NIS2 Directive, essential and important entities must now evidence how cybersecurity risks are governed, implemented, monitored, and improved over time.

This shift has made one thing clear: **modern compliance cannot exist without strong cyber fundamentals**.

That is where [**Cyber Fundamentals**](https://quantarra.io/?hsLang=en) **(CyFun)** plays a pivotal role not as a checkbox certification, but as a foundational framework that enables scalable, automated, and auditable compliance.

## **The Compliance Shift: From Point-in-Time Audits to Continuous Assurance**

Traditional compliance models rely heavily on:

- Periodic audits
- Manual evidence collection
- Spreadsheets and document repositories
- Last-minute remediation

However, NIS2 and similar regulations demand **continuous risk management**, not snapshot compliance. Regulators are increasingly focused on:

- How cybersecurity decisions are governed
- Whether controls are consistently applied
- How incidents are detected, responded to, and recovered from
- Whether organizations can *prove* this on demand

This is where cyber fundamentals become the backbone of compliance automation.

## **What Is Cyber Fundamentals (CyFun)?**

**Cyber Fundamentals (CyFun)** is a structured, risk-based cybersecurity framework originally developed in Belgium and now adopted by **Ireland as a co-owner of the scheme**.

CyFun is:

- **Voluntary and non-statutory**
- A **recognised method to organise and evidence controls**
- Strongly recommended by the **National Cyber Security Centre (NCSC)** as a way to support NIS2 obligations

Importantly, **CyFun does not automatically mean NIS2 compliance**. Final compliance determinations remain with the relevant National Competent Authority (NCA). CyFun is best understood as a **credible and structured way to demonstrate alignment** with regulatory expectations.

## **CyFun and NIS2: How They Fit Together**

Ireland’s NIS2 compliance framework will be established through the **National Cyber Security Act** and associated statutory instruments. These define *what* organizations must do.

CyFun supports this by defining **how organizations can organise, implement, and evidence those requirements** in a consistent, auditable manner.

The NCSC:

- Recommends CyFun as a **preferred method to demonstrate compliance**
- Aligns CyFun with published **Risk Management Measures (RMM)**
- Recognises that CyFun is **not the only route** — ISO 27001, NIST, COBIT, and other frameworks remain valid

This flexibility ensures organizations can build on existing security programs while maintaining regulatory consistency.

## **A Risk-Based, Tiered Model for Cyber Maturity**

One of CyFun’s strengths is its **tiered maturity approach**, which recognises that not all organizations face the same level of risk.

CyFun begins with an **initial selection tool** that assesses factors such as:

- Organisation size
- Sector and criticality
- Risk exposure
- Potential impact of a cyber incident

Based on this, organizations are assigned one of three levels:

- **Basic** – Foundational cybersecurity controls
- **Important** – Enhanced controls for higher-risk entities
- **Essential** – Stringent controls for entities of high societal or economic importance

For **important and essential entities under NIS2**, CyFun provides a pathway to **certification or formal assurance**, supporting externally validated compliance.

## **Alignment with NIST CSF 2.0: A Global Foundation**

CyFun is fundamentally based on the **NIST Cybersecurity Framework**, widely recognised as a global best practice.

- Current CyFun versions are grounded in **NIST CSF v1.1**
- A transition to **NIST CSF v2.0** is underway, expected by **Q3 2025**
- The NCSC is actively contributing to this update

Under NIST CSF v2.0, CyFun aligns with six core functions:

- **Govern** – Establishing cybersecurity risk strategy, policy, and oversight
- **Identify** – Understanding assets, risks, and vulnerabilities
- **Protect** – Implementing safeguards to prevent incidents
- **Detect** – Identifying cybersecurity events
- **Respond** – Managing and mitigating incidents
- **Recover** – Ensuring resilience and business continuity

This structure makes CyFun inherently suitable for **automation**, mapping directly to controls, workflows, and evidence systems.

## **Why CyFun Is the Backbone of Compliance Automation**

Modern compliance automation platforms depend on **clarity, structure, and traceability**. CyFun provides all three.

By structuring cybersecurity around defined functions and maturity levels, CyFun enables organizations to:

- Translate regulatory requirements into **clear, actionable controls**
- Continuously collect and organise evidence
- Maintain an always-ready audit posture
- Support multiple compliance frameworks in parallel
- Reduce reliance on manual, audit-driven processes

In short, **CyFun turns cybersecurity from an abstract obligation into an operational system** — which is exactly what automation requires.

## **Certification: Optional, but Strategically Valuable**

Certification under Cyber Fundamentals will be **optional**, with Ireland’s national certification system expected to take **18–24 months** to establish.

In the meantime, organizations are encouraged to:

- Use CyFun internally
- Align controls with the framework
- Begin preparing for formal assurance

Even without certification, CyFun can:

- Serve as a **trust signal in supply chains**
- Support regulator engagement
- Enable consistent internal governance

This makes CyFun both a **compliance enabler and a business differentiator**.

## **CyFun, RMM, and Regulatory Flexibility**

The NCSC’s **Risk Management Measures (RMM)** define the minimum baseline for NIS2 compliance — the *what*.

CyFun provides a structured way to address the *how*.

Organizations may still choose:

- ISO 27001 for information security
- ISO 62443 for industrial control systems
- Direct NCA assessments
- Self-assessments for lower-risk entities

CyFun complements these approaches, offering a **common language and structure** that regulators increasingly recognise.

## **The Future of Compliance Is Built on Cyber Fundamentals**

As regulations like NIS2 mature, organizations will be judged not just on whether controls exist, but on whether cybersecurity is **governed, repeatable, and demonstrable**.

Cyber Fundamentals (CyFun) provides the foundation for this future:

- Risk-based
- Standards-aligned
- Automation-ready
- Regulator-friendly

For organizations investing in [compliance automation](https://quantarra.io/blogs?hsLang=en), **CyFun is not an add on it is the backbone**.
