A mid-size public university in the Midwest, serving thousands of students across multiple campuses, was a Tenfold Security client. Tenfold Security was engaged on the day of the university's full network failure. The response to the university's ransomware attack used a parallel workstream model in which different response teams worked simultaneously on network analysis, device triage, forensics and communication. Tenfold Security deployed Sentinel One and Velociraptor across all university devices. Tenfold Security used Sentinel One for real-time endpoint detection and response and Velociraptor for rapid forensic collection and hunting for persistence mechanisms. Tenfold Security's response included identifying and closing the open RDP port and auditing all vendor access paths.

Tenfold Security's response included coordinating with cyber insurance to document the incident and manage communications.
