The short answer

The Cyber Governance Code of Practice is voluntary guidance for boards and directors, published by the Department for Science, Innovation and Technology with the NCSC on 8 April 2025. It sets out 22 actions under five principles: risk management, strategy, people, incident planning, response and recovery, and assurance and oversight.

The Cyber Governance Code of Practice is voluntary guidance that tells boards and directors which cyber security actions they personally own. It was published on 8 April 2025 by the Department for Science, Innovation and Technology (DSIT), developed with technical experts from the National Cyber Security Centre (NCSC) and governance experts from industry. It contains 22 actions grouped under five principles, and it is aimed at medium and large organisations in both the public and private sectors.

The Code is not a technical standard. It does not tell your IT team how to configure firewalls. It tells the board how to direct, resource and oversee cyber risk, and what assurance to ask for. The government pairs it with Cyber Essentials as the minimum an organisation should have in place: the Code for governance, Cyber Essentials for the basic technical controls.

What is the Cyber Governance Code of Practice?

It is the foundational code in DSIT’s set of cyber security codes of practice. Organisations that follow the more specialised codes, such as the Software Security Code of Practice or the AI Cyber Security Code of Practice (covered in our AI governance guide), should follow the governance code as well. The full text is on GOV.UK.

Two free resources support it: the NCSC’s Cyber Security Toolkit for Boards (see how the Code relates to the toolkit below) and Cyber Governance Training, which explains why and how boards should take each action. The Code is written for directors, not for the people who run security day to day, though security leaders can use it to show the board what is expected of it.

Is the Cyber Governance Code of Practice mandatory?

No. The Code is voluntary and creates no new legal obligations. It still matters for three reasons:

  • Directors’ existing duties. Directors of UK companies already owe statutory duties, including the duty under section 174 of the Companies Act 2006 to exercise reasonable care, skill and diligence. The Code gives boards a reference point for what reasonable attention to cyber risk looks like.
  • Internal controls declarations. Companies reporting against the UK Corporate Governance Code 2024 face Provision 29 for financial years beginning on or after 1 January 2026, which asks the board for a declaration on the effectiveness of its material internal controls. For many businesses, cyber controls are part of that picture.
  • Customer and insurer scrutiny. Large customers, insurers and investors increasingly ask how cyber risk is governed. A board that can show it follows the Code has a clear answer.

What are the five principles and the director actions?

The Code has five principles, A to E, with between four and five actions under each, 22 in total. The summary below paraphrases each action.

Principle What directors should do
A. Risk management (5 actions) Make sure the technology, information and services critical to the organisation are identified and prioritised; agree senior ownership of cyber risk and build it into enterprise risk management; define the cyber risk appetite; make sure supplier risk is assessed in proportion; make sure risk assessments are regular and reflect change
B. Strategy (4 actions) Make sure a cyber strategy exists and is embedded in the wider business strategy; check it matches the risk appetite and regulatory obligations; allocate resources to it; monitor whether it is being delivered
C. People (4 actions) Promote a positive cyber security culture; make sure clear policies support it; improve your own cyber literacy; use metrics to check that training and awareness work
D. Incident planning, response and recovery (4 actions) Make sure a response and recovery plan exists for business-critical services; make sure it is exercised at least once a year with internal and external stakeholders; take responsibility for regulatory reporting and critical decisions during an incident; make sure lessons from incidents feed back into plans
E. Assurance and oversight (5 actions) Set up a cyber governance structure with executive and non-executive ownership; require formal reporting at least quarterly with metrics and tolerances; hold regular two-way dialogue with the chief information security officer or equivalent; integrate cyber into internal and external audit; make sure senior executives know the relevant regulations and codes

Two actions set a fixed rhythm that most boards can adopt immediately: formal cyber reporting at least quarterly (principle E) and an incident response exercise at least once a year (principle D). A cyber tabletop exercise is the usual way to meet the second, and our incident response plan template and business continuity plan template give you the plans the exercise tests.

How does the Code relate to the NCSC Cyber Security Toolkit for Boards?

The Code says what directors should do; the toolkit explains how. The NCSC’s Cyber Security Toolkit for Boards is the resource the NCSC publishes to help boards implement the Code’s actions, and it is organised around the same principles, so each principle has its own section with background and practical guidance. Free downloads include the complete toolkit as a PDF, an executive summary, a list of questions for the board to ask (with possible answers) and a short “Cyber security 101” script for board members.

Use the two together. Take the 22 actions in the Code as the checklist the board signs up to, and turn to the matching toolkit section when you need to understand an action or decide what good evidence looks like. Neither creates a legal duty, and neither replaces the technical frameworks your security team works to.

How can Cyber Essentials, ISO 27001, PCI DSS and testing evidence support board reporting?

The Code asks directors to obtain assurance, not to do technical work. Independent certifications, assessments and test reports are the most reliable assurance a board can get, because someone outside the organisation has checked the evidence. Each source answers a different question, and each has limits the board should understand.

Evidence What it tells the board Principles Limits to keep in mind
Cyber Essentials and Cyber Essentials Plus Five technical controls are in place across the certified scope; CE+ adds hands-on testing A, E Covers common internet-based attacks only, within the stated scope
ISO 27001 certification A risk-based management system is operating, with internal audit, management review and independent certification audits A, B, C, E Scope-dependent; shows the system works, not that every control is strong
PCI DSS assessment (ROC and AOC, or SAQ) Controls protecting payment card data meet PCI DSS v4.0.1 A, E Limited to the cardholder data environment; an SAQ is a self-assessment unless a QSA has reviewed it
Penetration test reports How far an attacker could get today, and whether earlier findings were fixed A, D, E A snapshot of the systems tested, on the dates tested
Vulnerability scanning trends Whether known weaknesses are being found and fixed on time A, E Finds known issues; does not show how they could be chained together
Incident exercise reports Whether the response plan works and who decides what D Only as good as the scenario chosen

Ask for the scope statement with every certificate and report. A board that knows what was not tested is better placed than one that only sees a pass.

DSIT has also published official mappings of the Code to other frameworks, including ISO/IEC 27001:2022 and the NCSC Cyber Assessment Framework, so a board that already reports against one of them can reuse that structure.

What should the board ask each quarter?

Because principle E asks for formal reporting at least quarterly, many boards turn the Code into a standing agenda item. The questions below follow the five principles, so the answers show the board which of the 22 actions are slipping. For questions organised around technical controls rather than governance, see our NCSC 10 Steps to Cyber Security guide.

Principle Questions for the quarterly report
A. Risk management Which business-critical services and data would hurt most if lost, and has that list changed? Are we inside our agreed cyber risk appetite, and if not, what is the plan and by when? Which suppliers could disrupt critical services, and when were they last assessed?
B. Strategy Is the cyber strategy on track, and is it resourced to deliver this year’s priorities?
C. People What do our training and phishing metrics show, and what changed as a result?
D. Incident planning, response and recovery When was the incident response plan last exercised, and what did we change afterwards? Do we know our reporting obligations in an incident, and who on the board signs them off?
E. Assurance and oversight Who are the named executive and non-executive owners of cyber risk? What did the latest penetration test, vulnerability scans and audits find, and how many findings are overdue? Are our certifications current, and do their scopes still match the business? Has internal audit covered cyber this year? Has anything changed in regulation, contracts or insurance that affects our obligations?

How should a board start implementing the Code?

Start small and make it routine. A workable sequence is:

  1. Read the Code and the NCSC board toolkit together as a board.
  2. Agree executive and non-executive ownership of cyber risk.
  3. Rate the board against each of the 22 actions as in place, partly in place or not in place.
  4. Agree a cyber risk appetite and the metrics that will show whether you are within it.
  5. Book the annual incident exercise and set the quarterly reporting format.
  6. Build an assurance calendar covering certification renewals, audits and testing.
  7. Review progress against the 22 actions once a year.

The Code sits above the technical work, so pair it with a technical framework for the practices your team should run, such as Cyber Essentials for the basics or the CIS Controls for a fuller roadmap. For an independent view of where you stand, a cyber security audit gives the board a baseline to measure against. If the organisation has no senior security lead to report to the board, our guide to the virtual CISO (vCISO) explains how a part-time security leader can fill that gap.

What is the Cyber Governance Code of Practice?

It is government guidance that sets out the most important cyber governance actions for boards and directors. It groups 22 actions under five principles and is supported by the NCSC Cyber Security Toolkit for Boards and free Cyber Governance Training.

Is the Cyber Governance Code of Practice mandatory?

No. The Code is voluntary and creates no new legal duties. It does set out what the government and the NCSC regard as good board practice, so customers, insurers and investors may use it as a yardstick when they ask how your board oversees cyber risk.

Who wrote the Code?

The Department for Science, Innovation and Technology published it on GOV.UK on 8 April 2025. It was developed with technical experts from the NCSC and governance experts from industry, following a call for views in 2024 and a government response in January 2025.

Does the Code apply to small businesses?

It was designed for medium and large organisations in the public and private sectors. Smaller organisations are encouraged to follow its principles, and Cyber Essentials is usually the practical starting point for their technical controls.

How often should the board receive cyber security reports?

At least quarterly. Under principle E, the Code asks boards to require formal reporting on cyber risk at least every quarter, with agreed metrics and tolerances aligned to the cyber strategy and risk appetite.

How does the Code relate to Cyber Essentials?

The Code says that, together with Cyber Essentials, it sets out the minimum an organisation should have in place. The Code covers how the board governs cyber risk, while Cyber Essentials certifies five technical controls that protect against common internet-based attacks.

Does following the Code meet NIS, FCA or DORA requirements?

No. The Code is governance guidance, not a regulatory standard. Regulated organisations must still meet their own rules, including the NIS Regulations that the Cyber Security and Resilience Bill would extend, although the governance structure, reporting and exercising the Code describes will support that work.
