Contained in seconds, so the school day carries on.
Ransomware in education reaches more than IT. A school ransomware attack can close classrooms, delay exams and put pupil and staff data at risk. Helm contains ransomware at the data layer, so teaching can keep running, and holds the record governors, regulators and insurers expect.
Schools, trusts, districts and universities hold sensitive data on pupils, students and staff, and run timetables, learning platforms, exams and admissions on it. Many do this across several sites, and in universities, departments often run systems of their own.
Attacks get through. In Sophos’s 2026 survey of education institutions hit by ransomware, 58% of attacks ended in data encryption and the average recovery cost was $2.26 million. A quarter of institutions (26%) needed between one and three months to recover.
Most of the teams facing this are small, and they cannot watch every system all day. That is the reality for many IT leaders in education.
85%
of ransomware attacks on education used identity-based techniques (stolen or abused credentials).
In England, the DfE’s cyber security standards for schools and colleges ask for at least three backup copies of important data on at least two devices, one of them off-site, with backups that cannot be changed and are tested every term. They also ask for a cyber response plan as part of business continuity, which is a condition of cover under the DfE’s risk protection arrangement.
Elsewhere, ransomware in education falls under general data protection law and, for some universities, by NIS2. Wherever you are, the questions after an incident are similar. What happened, what was affected, and how quickly systems were verified clean and back?
Helm supports the answers. It contains an attack early, so less has to be restored from those backups, verifies that systems are clean before they come back, and records every step for your response plan, your insurer and your governors.
Helm protects the file servers and shares where coursework, records and administration live, on site and in Microsoft 365, with nothing installed on pupil or staff devices.
When encryption starts, Helm detects it in under a second and responds on rules your team sets, with no AI involved and no one needed at a screen in the evening or during the holidays. It isolates the compromised accounts and devices, often the result of a phishing email, while the rest of the school or campus carries on.
Recovery is not done until it is verified clean. Helm verifies that systems are clean before they come back, so teachers and students return to coursework and records they can trust.
Every step is logged with a timestamp, giving your team the facts for the data protection authority, your board or governors and your insurer.
Ransomware will keep targeting schools and universities. With Helm, attacks are contained in seconds, teaching carries on, and systems come back only once they are verified clean.
