Case Study: Colchester Institute achieves 100% ransomware data recovery and $0 ransom paid with Rubrik Zero Trust Data Security

How Colchester Institute Recovered from a Crippling Ransomware Attack within Days

Colchester Institute, the largest vocational college serving North Essex, was hit by a sophisticated ransomware attack in April 2021 that disabled admin accounts, deleted email and key servers, and encrypted its VMware/ESXi environment — putting finance, student records, admissions and day-to-day communications at risk.

Working with KHIPU Networks, Colchester used Rubrik’s Zero Trust Data Security to restore operations from immutable backups, analyze impacted files, and recover to the most recent clean copy with one click. The institute experienced 0% data loss, paid $0 in ransom, and achieved 100% data recovery within 10 days, while also reducing infrastructure complexity and realizing rapid ROI — leading them to recommend Rubrik to other education providers.
