South Korea has temporarily blocked employee access to Chinese AI startup DeepSeek over security concerns. A government notice urged ministries and agencies to exercise caution when using AI services, including DeepSeek and ChatGPT. Korea Hydro & Nuclear Power, the defence ministry, and the foreign ministry have all imposed restrictions on DeepSeek access.

Australia and Taiwan have already banned DeepSeek from government devices, citing security risks. Italy previously ordered the company to block its chatbot over privacy concerns. Authorities in the US, India, and parts of Europe are also reviewing the implications of using the AI service. South Korea's privacy watchdog plans to question DeepSeek on its handling of user data.

Korean businesses are also tightening restrictions on generative AI. Kakao Corp advised employees to avoid using DeepSeek, despite its recent partnership with OpenAI. SK Hynix has limited access to generative AI services, and Naver has asked employees not to use AI tools that store data externally.

DeepSeek has not yet responded to requests for comment. The company's latest AI models, released last month, have drawn attention for their capabilities and cost efficiency. However, growing security concerns are leading governments and corporations to impose stricter controls on their use.
