Improving Cyber Resilience
We would urge all schools and multi academy trusts to work on their cyber resilience, firstly by training their staff and making cyber awareness part of the organisation's ethos. Secondly, we would recommend reviewing the DfE Digital Standards. Our customers have access to a free Leadership & Governance Tracker to assess where you are with your digital strategy and Cyber Security Best Practice Area. If you would like access to this and other trackers, further information can be viewed:
What to do in the event of a cyber attack
First, follow your cyber response plan. Record the incident in your internal incident log, inform your governing board or trustees, and contact your Data Protection Officer (DPO) as soon as possible if personal data could be involved.
Incidents or attacks where a security breach may have taken place, or other damage was caused, should also be reported to an external body. The SLT digital lead is responsible for assigning someone to report any suspicious cyber incidents or attacks. This person will need to report to:
- Report Fraud, which replaced Action Fraud in December 2025, on 0300 123 2040 or through the Report Fraud website. Make sure it is recorded as a crime report so that you receive a crime reference number.
- the DfE sector cyber team at

You may also need to report to:
- the National Cyber Security Centre (NCSC) if the incident or attack causes long-term school closure, the closure of more than one school, or serious financial damage. If you're not sure who to report to, use the government's cyber incident signposting service.
- the Information Commissioner's Office (ICO) within 72 hours of becoming aware of a personal data breach, unless the breach is unlikely to result in a risk to people's rights and freedoms. If the risk is high, you must also tell the people affected without undue delay. Your DPO can help you assess this. We will do this on behalf of DPE customers.
- the Risk Protection Arrangement (RPA) emergency assistance helpline on 0800 368 6378 or

- any third-party service providers whose systems are affected, so they can be part of a coordinated response
- Jisc CSIRT, if you are part of a further education institution.
You must act in accordance with:
- Report Fraud's guide to reporting cyber crime and fraud
- Academy Trust Handbook Part 6, if you are part of an academy trust. Since September 2025, academy trusts must not pay any cyber ransom demands.
- the ICO's guidance on personal data breaches.
Preserve the evidence
Police investigations may find out whether any compromised data has been published or sold, and identify the perpetrator. Preserving evidence is as important as recovering from the crime. Keep a clear record of what happened, when, and what actions you took. The DfE's guidance on record keeping in an incident explains what to capture.
