Case Study: Dudek prevents 8.5k advanced email attacks and frees IT time with Abnormal AI

Fast-Growing Dudek Drives Progress, Delivers Excellence from Its People Across the Nation

Dudek, a 700+‑person environmental consulting and engineering firm, was facing a surge in sophisticated credential phishing and vendor email compromise attacks that were bypassing its Microsoft 365 defenses and creating heavy manual remediation work. Seeking a lightweight, Microsoft‑compatible solution that could be deployed quickly, Dudek selected Abnormal AI and its ICES Inbound Email Protection to stop advanced email threats and protect executives and finance teams.

Abnormal AI integrated ICES via API into Dudek’s Microsoft 365 environment in about 30 minutes and added VendorBase™ and account‑takeover protections that immediately reduced security overhead and blocked attacks. The deployment prevented 8.5k attacks in the first four months, saved roughly 20 IT hours per month, cut daily phishing tickets from five–six to essentially one quarantined incident, and helped stop a vendor email compromise that would have redirected funds—delivering measurable risk reduction and time savings for Dudek.
