Case Study: Evercore achieves seamless email security and protection from human error with Proofpoint

Mitigating Inbound and Outbound Email Threats

Evercore, a global independent investment bank with roughly 2,000 employees across major financial centers, needed a reliable email security solution that wouldn’t disrupt highly transactional workflows. After a two‑year search for data‑loss prevention and anti‑phishing tools, the firm prioritized a product that could be deployed quickly, require minimal integration, and prevent costly human errors without causing downtime.

Tessian delivered a machine‑learning Human Layer Security platform that retroactively learns normal email behavior and integrates directly with Outlook, Office365 and G Suite. The lightweight add‑in was up and running within hours, rolled out at IT’s pace, and immediately reduced misdirected emails and spear‑phishing risk across Evercore’s global workforce—earning strong praise from the CIO and positive feedback from multiple employees.
