Case Study: Asset Management Firm achieves immediate protection and 100x fewer false positives with Proofpoint

Why an Asset Management Firm Chose Tessian Defender Over a Well-Known, ML-Based Competitor

A global asset management firm that serves institutions, endowments, charities, advisors and retail investors faced sophisticated spear-phishing attacks that native tools and rule-based defenses couldn’t stop. With a lean IT team and existing Tessian deployments for data loss protection, the firm needed an easy-to-manage, ML-powered solution that would complement their Secure Email Gateway; after trialing a competitor, they selected Tessian Defender.

They deployed Tessian’s full Cloud Email Security platform, whose behavioral intelligence ingests 12 months of historical data for immediate protection. In the first week Defender flagged a dozen malicious events with virtually no false positives—about 100x fewer than the competitor—while configurable in-the-moment warnings reduced admin overhead, empowered users to report and delete threats, and reinforced security awareness (including integration with KnowBe4).
