Case Study: Polarcus reduces spear‑phishing risk and protects critical data with Proofpoint

Tackling Spear Phishing when the Stakes are High

Polarcus, a Dubai‑headquartered leader in offshore geophysical services with about 350 employees and listed on the Oslo stock exchange, faced a rising risk from targeted spear‑phishing attacks that could lead to data theft or system takeover. Legacy security tools and rule‑based controls left individuals exposed to highly tailored impersonation emails that used urgency and social pressure to bypass traditional defenses.

Polarcus deployed Tessian Defender, which uses stateful machine learning to provide contextual, real‑time warning messages to users and surface why an email may be suspicious. The solution filled a critical gap in their security stack—alerts are infrequent but highly visible and effective—acting as an “insurance policy” alongside existing tools and materially reducing the risk from sophisticated spear‑phishing attempts.
