# xorlab Raises €5M Series A to Expand Sovereign Email Security Across Europe

> Zurich-based xorlab has raised a 5 million euro Series A, led by Spicehaus Partners, to expand its behavioral AI email security platform across Europe. Founded in 2015 by Antonio Barresi, the company already counts Julius Bar, Swisscom, Vontobel, and CERN among its customers. xorlab's approach is to model normal communication behavior and flag deviations, targeting the sophisticated phishing and business email compromise attacks that increasingly rely on AI to sound convincing. The framing is deliberately European: the company pitches sovereign email security, keeping sensitive defensive infrastructure under regional control rather than depending on US providers. Expansion is aimed at the DACH region, Benelux, and the Nordics. The round is modest, but it sits at an interesting intersection. As attackers use generative AI to craft cleaner, more targeted lures, behavioral defense that watches for anomalies rather than known-bad signatures becomes more valuable, and European buyers' growing appetite for data sovereignty gives a local player like xorlab a real opening.
