Case Study: Texas Trust Credit Union achieves email threat protection and improved network availability with Fortinet

Texas Trust Credit Union Protects Its Employees and Members With Email Security and the Fortinet Security Fabric

Texas Trust Credit Union, a Dallas–Fort Worth financial institution founded in 1936 with 23 branches and $1.7B in assets, faced escalating email-based threats — receiving about 250,000 emails per month (roughly 50,000 spam) and frequent malware, spear-phishing, and CEO‑spoofing attempts. With ransomware a major concern and strict regulatory obligations to protect member data, the credit union needed stronger, easy-to-manage email defenses and better visibility across its network.

Texas Trust deployed Fortinet’s FortiMail and the broader Fortinet Security Fabric (including FortiGate SD‑WAN, FortiAnalyzer, FortiEDR, FortiAuthenticator, and FortiAP), adding DLP, quarantine controls, and endpoint protection. The result: blocked advanced email threats, improved compliance with GLBA/NIST guidance, a single-pane-of-glass view for faster incident correlation, and greater network availability and reliability through SD‑WAN redundancy — reducing downtime and simplifying security operations as the credit union prepares to move email to Microsoft 365 and FortiMail Cloud.
