Cyber security in schools has moved from being a purely technical concern to a whole-school safeguarding priority. Going into 2026, schools and multi-academy trusts face more targeted, more disruptive, and more education-aware cyber threats than before. Attackers know that schools hold rich personal data. They also know that schools run lean IT teams and cannot afford downtime. That combination makes education a growing target. This guide covers the seven biggest cyber security risks facing UK schools in 2026. For each one, we outline practical planning priorities. The government’s Cyber Security Breaches Survey has tracked this trend closely. It found that a large share of secondary schools experienced a breach or attack in the past year. That figure shows how live this issue has become for IT leads and senior leadership. For a fuller picture of how to protect your school, see our guide to cyber security for schools.
1. Ransomware Designed to Disrupt Learning, Not Just Data
Ransomware attacks on schools are becoming increasingly strategic. Rather than simply encrypting files, modern attacks now target MIS systems, safeguarding platforms, timetabling, assessment data, and cloud identity services. As a result, a single incident can bring lessons, exams, and safeguarding processes to a standstill within hours. To prepare, schools should prioritise immutable offline backups, rapid restore processes, and incident response plans that align directly with safeguarding procedures.
2. Phishing Attacks Tailored to the School Calendar
Phishing has also become far more contextual. Attackers now time highly targeted emails around exam periods, Ofsted inspections, safeguarding referrals, and payroll deadlines, exactly when staff are busiest and least likely to scrutinise a message closely. Consequently, schools should invest in role-based phishing training, realistic simulations, and technical controls that reduce reliance on individual judgement alone.
3. Compromised Staff Accounts via MFA Fatigue
Meanwhile, attackers increasingly exploit multi-factor authentication itself, bombarding staff with approval requests until one is accepted out of frustration or habit. To mitigate this risk, schools can introduce number-matching MFA, set up authentication alerts, and give staff clear guidance on what a genuine login request should look like.
4. Cloud Misconfiguration and Over-Permissioned Accounts
In addition, misconfigured cloud environments remain a major source of risk, particularly excessive admin permissions and active leaver accounts that are never switched off. Regular permission audits, least-privilege enforcement, and automated account management are therefore essential parts of good school cyber security.
5. Third-Party and Supply Chain Vulnerabilities
Furthermore, a breach at an education supplier can affect a school just as directly as an internal incident would. For this reason, security due diligence, robust data processing agreements, and clear vendor visibility are critical, both before a contract is signed and throughout the relationship.
6. IoT and Smart Building Technology Risks
CCTV, access control, and smart building systems are often installed without adequate security review, which can leave an unexpected gap in the wider network. Network segmentation, up-to-date asset inventories, and regular security reviews of connected devices all help to close this gap. Schools reviewing their CCTV and access control systems should ask their supplier how these devices are secured on the network, not only how well they perform.
7. Incident Response Gaps That Delay Safeguarding Decisions
Finally, unclear or untested response plans can significantly worsen the impact of a cyber incident. Schools should therefore align their cyber incident response with existing safeguarding policies and rehearse scenarios regularly, so that staff know exactly what to do, and who to call, within the first hour of an incident.
Cyber Security in Schools: Building Real Resilience
Ultimately, cyber security in schools is about preparedness, not just prevention. Schools that recover fastest are the ones that assume an incident will happen eventually and plan accordingly, rather than hoping it never will. For further free guidance, the National Cyber Security Centre publishes resources specifically for education settings.
SchoolCare supports schools and multi-academy trusts with cyber security assessments, resilience planning, and safeguarding-aligned strategies built around the DfE Digital Standards. Whether you are just starting to map out your 2026 priorities or reviewing an existing plan, working through these seven areas is a practical place to begin.
