Case Study: PSE S.A. Secures Critical Systems with Appgate

Utility Company PSE S.A. uses SDP to secure critical SCADA and EMS Applications

PSE S.A., Poland’s transmission system operator, needed secure, flexible access for employees, traders, contractors, and third-party suppliers to mission-critical SCADA and EMS systems. To protect sensitive electricity market operations and ensure 24/7 availability, the company turned to Appgate and its SDP-based secure access solution.

Appgate implemented a highly flexible access control environment with strong two-factor authentication, contextual authorization, persistent encryption, and clustered high availability. PSE S.A. used Appgate to create separate secure access paths for internal systems, market traders, technical support, and remote employees, improving precision, resilience, and ease of administration while supporting continuous operations without downtime.
