Case Study: SPG Dry Cooling achieves advanced phishing protection and prevents spoofing with Proofpoint

How Tessian is Preventing Advanced Impersonation Attacks in Manufacturing

SPG Dry Cooling, a global leader in air‑cooled condensers, faced increasingly sophisticated email threats that were slipping past Office 365 controls and employee training. Attackers used subtle domain impersonation and spoofing—once even trying to initiate a wire transfer by swapping a top‑level domain—so the IT team needed a way to stop advanced impersonation attacks before they reached users.

SPG deployed Tessian Defender across 368 users; the solution ingested up to 12 months of historical email data and uses NLP, behavioral and communication analysis to spot anomalies in real time. Tessian automatically blocks threats, offers plain‑English in‑the‑moment warnings to educate users, provides one‑click denylisting and actionable dashboards, and was quick to connect to Office 365—reducing manual investigations and preventing advanced spoofing and spear‑phishing attempts.
