U.S. Immigration and Customs Enforcement is launching a new “Doxing Mitigation Initiative” using AI to help ICE personnel keep their identities hidden from the public, according to an email addressed to all agency employees on Monday.

The memo, signed by Acting ICE Director David Venturella and leaked to The Intercept by ICE employees, identifies a company called ZeroFox as the tech firm behind the initiative. The communication describes ZeroFox as “a modernized protective technology solution designed to strengthen safeguards for our most valuable resource: You and your families.”

The Department of Homeland Security, ICE’s parent agency, quietly entered a $15 million contract with ZeroFox in July for software licenses to support ICE operations and investigations, according to public procurement records. The records indicate that ZeroFox will provide services for the Office of Intelligence at ICE’s Homeland Security Investigations division.

ZeroFox develops AI-driven software aimed at stopping data leaks across social media and the dark web, according to its website. “ZeroFox never stops finding, mapping, and monitoring your digital presence,” the company vows. It’s not clear from the contract or the internal email how, precisely, the new initiative will function, and neither ICE nor ZeroFox responded to requests for comment.
