US bans DeepSeek from government systems: is DeepSeek safe to use?
The US Department of Homeland Security has ordered federal agencies to remove DeepSeek AI, including tools built on it. Here's why, what it means for everyday users, and how to use AI chatbots safely.
The US government has ordered its agencies to stop using DeepSeek, the popular Chinese AI chatbot. On October 20, 2026, the Department of Homeland Security (DHS) published an order requiring federal civilian agencies to remove DeepSeek products from their systems.
Many people use DeepSeek because it’s free and powerful. So is it safe for you? Here’s what you need to know.
What does the ban cover?
- Federal civilian agencies must stop buying DeepSeek products immediately.
- They must remove existing DeepSeek products from government IT systems.
- The order also covers DeepSeek’s affiliates and third-party products built on DeepSeek technology.
- Agencies can ask for exceptions within 60 days; CISA, the US cybersecurity agency, will review them.
Earlier, a December 2025 law had already restricted DeepSeek in US intelligence and national security systems. This order extends that to civilian agencies.
Why was DeepSeek banned?
According to the order and reports, the main concerns are:
- Data access: because DeepSeek operates in China, US officials worry Chinese authorities could access user data under Chinese law.
- Tracking and data collection: concern that the service could collect personal information and track users.
- App security: the order cites a 2025 report by security firm NowSecure that found problems in DeepSeek’s iPhone app, including unencrypted data transfers and weak encryption.
China’s Foreign Ministry criticized the move, saying the US is “politicizing technology and trade issues.”
Is DeepSeek banned for normal users?
No. The order applies only to US federal civilian agencies. It’s not a ban on personal or consumer use. You can still download and use DeepSeek in most countries, although some governments and companies have their own restrictions.
So, is DeepSeek safe to use?
It depends on what you use it for:
- Lower risk: general questions, learning, brainstorming, public information.
- Higher risk: anything personal, confidential or work-related, such as passwords, ID numbers, financial details, health information, company documents or private code.
A simple rule: don’t type anything into an AI chatbot that you wouldn’t be comfortable seeing in someone else’s hands.
How to use DeepSeek (and any AI chatbot) more safely
- Never share sensitive data: passwords, bank details, ID numbers or private work documents.
- Check your workplace rules. Many companies ban certain AI tools for work.
- Use the web version instead of the app if you’re worried about app permissions, and review what permissions the app has.
- Delete chat history you don’t need, where the service allows it.
- Consider running open models locally. DeepSeek’s models are open-weight, so developers can run them on their own computers or trusted servers, which keeps data off DeepSeek’s servers.
