Case Study: Crestline Sanitation District achieves secure SCADA access and 51-75% productivity gains with SonicWall SMA

Crestline Sanitation District - Customer Case Study

Crestline Sanitation District, a government utility serving about 10,000 residents in Crestline, CA, faced identity-based secure access challenges protecting its SCADA systems and enabling remote device/user access. They standardized on SonicWall and deployed SonicWall SMA to provide role-based access control, secure VPN connectivity, and isolation of the SCADA network (primarily for tablet access).

SonicWall implemented SMA appliances to deliver identity-driven VPN access and SCADA access control, simplifying access management and providing single-pane-of-glass visibility. As a result, Crestline reports a 51–75% improvement in productivity, enhanced efficiency managing a distributed secure access infrastructure, increased end-user productivity, and improved regulatory compliance.
