  • Implementation walkthrough
  • 3 min 15 s

Key takeaways

  • Cyber Essentials covers five controls: firewalls, configuration, updates, access and malware protection.
  • Agree the scope with the certification body before the assessment.
  • Some questions are automatic fails, and the board signs the declaration.
  • Cyber Essentials Plus adds a technical audit within three months.
  • Both certificates expire after 12 months.

Five technical controls against common attacks

Cyber Essentials is the UK government-backed certification scheme that shows an organisation has five basic technical controls in place: firewalls, secure configuration, security update management, user access control and malware protection. It is the scheme of the National Cyber Security Centre, which calls it the minimum standard of cyber security the Government recommends for organisations of all sizes. IASME, the NCSC's delivery partner, runs it through certification bodies it licenses.

There are two levels. Cyber Essentials is a verified self-assessment: the organisation answers the question set online and a licensed certification body marks the answers. Cyber Essentials Plus adds a technical audit. This short film walks through how an organisation prepares for both.

Controls first, accurate answers second

Define the scope, the legal entities and the level: the whole IT infrastructure or a well-defined, separately managed sub-set segregated by a firewall or VLAN, the legal entities covered, and whether the target is Cyber Essentials or Plus. The scope covers end-user devices, servers, home and remote working, personal devices that reach organisational data, and cloud services, and it is agreed with the certification body before assessment begins.

A gap analysis then checks each of the five controls against every device, account and service in scope, and remediation closes the gaps: firewall rules reviewed, default settings changed, updates applied within the required time, administrative access restricted and malware protection in place. Some questions are automatic fails, so every answer has to be true. The self-assessment is submitted, marked by the certification body and signed off by the organisation's own board. For Plus, the technical audit follows within three months of the Cyber Essentials certificate. Both certificates expire after 12 months, so renewal is part of the plan.

Sterling's expert and experienced consultants support scope, gap analysis and control remediation with your IT team under Sterling OS™. The certificate comes from the IASME-licensed certification body.

Cyber Essentials: questions people ask

What is the difference between Cyber Essentials and Cyber Essentials Plus?

Both certify the same five controls. Cyber Essentials is a verified self-assessment, signed as true by a board member and marked by a qualified assessor from a licensed certification body. Plus adds a hands-on technical audit: a remote vulnerability assessment, an authenticated scan of sampled devices, and checks of malware protection, multi-factor authentication and account separation, within three months of the Cyber Essentials certificate and on the same scope.

Is Cyber Essentials mandatory for UK government contracts?

For many of them. PPN 014, for procurements started from 24 February 2025, requires central government departments, their agencies and non-departmental public bodies and NHS bodies to apply it to contracts involving citizens' or government employees' personal data, or ICT systems and services handling OFFICIAL data. A supplier without the certificate must show equivalent controls by other means, and certification is renewed every year of the contract. Defence suppliers follow Def Stan 05-138: Cyber Essentials at every risk level, Plus from Level 1.

How long is a Cyber Essentials certificate valid?

Twelve months, at either level. The certificate describes your controls at a point in time, defined by the scheme as the date of issue, so renewal is a fresh assessment each year. Buyers can check that a certificate is current on the NCSC certificate search, which lists those issued in the last 12 months.

Can we certify only part of the organisation?

Yes, if that part is a well-defined, separately managed sub-set whose network is segregated from the rest by a firewall or VLAN, and the scope is agreed with the certification body beforehand. End-user devices must be included and cloud services cannot be excluded. Under Danzell you name every legal entity in scope and describe what is left out; the exclusions are not published. The included cyber liability insurance applies only when the whole organisation is certified.

Which questions are automatic fails, and what happens if we fail?

Unsupported software anywhere in scope fails the assessment. Under Danzell, so does a cloud service without multi-factor authentication where it is available, and a critical or high-risk update not applied within 14 days to operating systems and router or firewall firmware (question A6.4) or to applications (A6.5). The assessor's report explains every non-compliant answer, and IASME allows two working days to fix simple issues and update the answers without a further fee.
