The US House of Representatives has imposed a ban on the use of Microsoft Copilot on government-owned devices by congressional staff. This decision was made by the Office of Cybersecurity due to concerns about the potential for sensitive data to be leaked to cloud services that are not approved by the House. The ban specifically targets the current commercial version of Copilot, and it follows previous restrictions on similar AI-driven tools. Microsoft has acknowledged the ban and expressed understanding of the government's need for stringent security measures. In response, the company is planning to introduce new tools with enhanced security features designed for government use, including an Azure OpenAI service for classified workloads and a version of Microsoft 365's Copilot assistant tailored for such environments.
