Case Study: Affinity Credit Union reduces spam by 75% and slashes email management time with Mimecast

Affinity Credit Union Turns to Mimecast to Stave Off Increasing Volume of Phishing Attacks

Affinity Credit Union, the eighth-largest credit union in Canada with 56 locations and 750 employees, faced a rising volume of increasingly sophisticated phishing attacks that overwhelmed its two on‑premises email security appliances. IT staff were spending hours each week on manual workarounds, dealing with false positives and a growing number of support tickets—an unsustainable situation for EVP and CIO Michael Elchuk.

After consulting Gartner, Affinity implemented Mimecast’s cloud-based email security and continuity services—sandboxing and attachment scanning, self-service quarantines, automatic encryption, and user awareness training—supporting an upcoming migration to Office 365. The result: spam reduced by 75%, far fewer successful attacks and support tickets, significantly less time spent on email management, and high user satisfaction with Mimecast’s accurate threat protection and daily spam digests.
