According to the DfE (Department for Education), cyber incidents in schools and colleges can lead to safeguarding issues, significant data breaches, financial loss, reputational damage and lasting disruption, including closures. This is why one of the six core standards for schools and colleges set by the Department is cyber security. It expects schools and colleges to meet these standards by 2030.
The issue for most schools now is how to meet the DfE’s expectations, protect sensitive data and strengthen resilience in a way that is proportionate, efficient and affordable.
This guide explains the main cyber risks schools face, the basic controls every school should have in place and why Cyber Essentials certification is often a sensible next step for schools that want a clear technical assurance framework to support the wider aims of the DfE standard.
Why schools are increasingly targeted
Schools process large amounts of sensitive information, including pupil data, safeguarding records, medical information, staff HR files, parent contact details, financial data and account credentials.
They also rely on systems that need to stay available. If staff lose access to email, file storage, management information systems, payment platforms or teaching resources, disruption can affect both learning and core operations.
The biggest cyber risks schools face
Ransomware
Ransomware remains one of the most serious cyber risks facing schools.
A successful attack can lock access to systems and data, interrupt lessons, disable administration and create immediate pressure to recover with limited time, budget and internal resource.
That impact can spread quickly. Staff may lose access to email, teaching materials, attendance systems, safeguarding records, finance platforms and other core services needed to run the school day.
Data breaches
A school data breach can expose highly sensitive information.
That may include pupil records, safeguarding information, medical details, staff HR data and parent contact information.
The consequences are not limited to data protection compliance. A breach can trigger investigations, create reputational damage and undermine confidence among parents, staff, governors and trustees.
Operational disruption
Cyber incidents do not have to involve mass data theft to be damaging.
In many cases, the immediate problem is disruption. A compromised account, a phishing attack or a poorly secured system can affect access to email, file storage, management information systems, payment platforms and other everyday services.
This is especially relevant for schools using Microsoft 365, Google Workspace and other Cloud platforms, where a single compromised account may affect multiple systems at once.
For schools and trusts, that can mean lost time, cancelled work, delayed communications and significant pressure on already stretched teams.
Safeguarding implications
Cyber security failures in schools can also cause safeguarding issues.
If sensitive pupil information is exposed, accessed inappropriately or sent to the wrong person, the impact may go beyond privacy and operational disruption.
Schools handle confidential data relating to children, families and vulnerabilities. That means weak access controls, poor account management and accidental disclosure can all create safeguarding risks.
The five Cyber Essentials controls every school should get right
Cyber Essentials is a UK government-backed scheme that helps organisations protect themselves from common cyber threats.
Developed by the NCSC (National Cyber Security Centre) and administered by IASME, the scheme sets out five basic technical controls that can help schools reduce their exposure to common attacks, and meet the wider aims of the DfE cyber security standard:
Firewalls
Firewalls help protect your systems from unauthorised network access. Schools must ensure in-scope devices are protected by correctly configured firewalls, change default admin passwords, block unauthenticated inbound connections and tightly control access to firewall management interfaces.
Secure configuration
Secure configuration means removing unnecessary accounts and software, changing default or guessable passwords, disabling unsafe auto-run features and making sure users must authenticate before accessing organisational data or services. Devices also need suitable locking controls.
Security update management
All in-scope software must be licensed, supported and kept up to date. Critical, high-risk and otherwise unclassified security updates must be applied within 14 days, and unsupported software must either be removed or isolated from internet traffic through a defined sub-set.
User access control
Schools must control who has access to systems and data, use unique credentials, remove accounts that are no longer needed and require MFA for Cloud services. Administrative activity should be carried out through separate admin accounts only.
Malware protection
Malware protection is there to stop malicious software and code from running. This can be achieved through anti-malware software or application allow listing, provided the controls are configured and maintained in line with the scheme’s requirements.
Cloud-first schools: what the 2026 Cyber Essentials changes mean
Each year, the Cyber Essentials scheme is revised to ensure it remains relevant to the current threat landscape. The 2026 updates take effect on 27 April.
The scheme now places much stronger emphasis on Cloud services and identity security. From 27 April, if an organisation’s data or services are hosted on Cloud services, those services cannot be excluded from scope.
For schools, that matters a great deal. Email, file storage, collaboration, identity, management information systems, HR platforms and finance systems may all sit in Cloud environments. Those services still need to be reviewed as part of the school’s security arrangements.
The 2026 requirements also make the position on authentication clearer, requiring organisations to implement MFA (multifactor authentication) where available. Authentication to Cloud services must always use MFA.
For many schools, that means reviewing the security of Cloud services such as Microsoft 365 Education and Google Workspace.

Do schools need Cyber Essentials?
Although Cyber Essentials is mandatory for colleges under their funding agreement, it isn’t a requirement for schools. However, many schools and trusts achieve certification to demonstrate good cyber practice.
Certification offers a recognised and comparatively cost-effective way to review and evidence the technical controls that underpin day-to-day security.
Governors, trustees, senior leaders and parents may not want a detailed account of every control in place. They do want confidence that the school is taking recognised, proportionate steps to protect data and reduce disruption.
The DfE says its standards can help schools work towards Cyber Essentials certification.
