Case Study: Large U.S. Utilities Company achieves faster network changes, automated compliance tracking, and reduced downtime with Tufin

Large U.S. Utilities Company Cuts Network Change Time, Automates Compliance Tracking, and Reduces Downtime

Large U.S. Utilities Company faced a critical challenge: securing a complex, highly regulated network that spans 2,500+ firewalls and thousands of devices while protecting public safety. Manual change processes, poor visibility, and compliance obligations (e.g., NERC CIP) created months‑long SLAs, a backlog handled by nearly 40 people, and an inability to find and remediate shadowed rules. The company selected Tufin and deployed Tufin SecureChange and Tufin SecureTrack to address change orchestration, policy verification, and automated rule tracking.

Tufin implemented centralized change automation, continuous policy checks, path analysis for outage root‑cause, and automated shadow rule discovery. As a result, rule change SLAs dropped to under one week (from 2+ months), outage resolution time fell by 50%, time to find and remediate shadowed rules declined by 80%, staffing for change requests shrank from ~40 to 5 people, and compliance audit preparation went from weeks to about 2 hours.
