ICE more than tripled the amount of data it holds on Microsoft servers between July 2025 and January 2026, at the same time as the agency’s crackdown on migrants broke new records and sparked mass protests across the United States. Whereas last July the agency was storing around 400 terabytes of data in Microsoft’s cloud platform, Azure, by the end of January that had risen to almost 1,400 terabytes — equivalent to approximately 490 million images.

ICE employs a powerful arsenal of surveillance technology, reportedly using facial recognition software, drones, phone location tracking, mobile spyware, and even tapping school cameras. The leaked documents show ICE is using Microsoft’s AI video analysis tools including Azure AI Video Indexer and Azure Vision, which enable customers to analyze images, read text, and detect certain words, faces, emotions, and objects in audio and video files.

The agency is also understood to have significantly expanded its access to Microsoft’s suite of productivity apps, which include document management tools and an AI chatbot. However, the files do not specify whether ICE’s vast surveillance trove is being stored on Azure, or whether the agency is using the cloud platform for other operations instead, such as running detention centers or coordinating deportation flights.
