Case Study: eCISO achieves 5-minute BEC mitigation and instant email threat response with GreatHorn

eCISO - Customer Case Study

eCISO, led by founder Jeff Kohrman, is a boutique cybersecurity consulting firm that helps growth-stage companies build mature, scalable security programs. Facing a massive spike in cloud email volume (from about 5 million to 500 million messages per month), frequent targeted and BEC attacks, and a need to investigate threats without compromising user privacy, eCISO turned to GreatHorn’s cloud email security and remediation platform—using its proactive alerts and alert-driven training features to protect people and data without invasive content inspection.

GreatHorn delivered integrated email threat detection, instant alerts, and remediation tools that eCISO used to embed security awareness into everyday workflows and streamline incident response. The platform removed the need for manual API scripts, let teams see who received or opened malicious messages and redact content, and enabled security, IT, and analysts to act from a single browser. As a result, GreatHorn helped cut BEC detection-and-response from 4–6 hours to real time—highlighted by a recent mitigation completed in five minutes—improving speed, scalability, and operational efficiency.
