Case Study: Haverhill Public Schools recovers from ransomware in 24 hours with ClassLink

Haverhill Makes Quick Recovery From Ransomware Attack With ClassLink

Haverhill Public Schools, a K–12 district in Massachusetts serving more than 8,000 students, faced a major challenge when a ransomware attack encrypted its virtual servers and shut down access for students and staff. The district had already been using ClassLink for single sign-on, rostering, provisioning, and analytics, including OneSync and Roster Server, before the attack hit.

Using ClassLink’s offsite cloud-based backups and redundancy, Haverhill quickly restored authentication and rostering systems, got the environment clean, and brought school operations back online within 24 hours. With ClassLink, the district avoided paying the ransom and lost only one day of school, resuming learning quickly after the attack.
