US Department of Homeland Security bans DeepSeek from federal civilian agencies

The US Department of Homeland Security ordered federal civilian agencies to remove all DeepSeek AI products from their information technology systems and barred future procurement of the Chinese startup's technology. The directive, signed in July and published in October, applies broadly to DeepSeek-developed products and third-party services built on DeepSeek models. South China Morning Post reported that industry experts warn the ban could deter US companies from adopting low-cost Chinese AI models more broadly, extending the government's restrictions into private-sector decision-making.
