Securing DeepSeek
Control DeepSeek Use Before Your Data Leaves for China
DeepSeek's chat app is free, capable and widely used. Its privacy policy says it stores data on servers in the People's Republic of China, and several European data protection authorities have opened investigations or ordered restrictions on its app. Check the current policy and the position of your own regulator.
For most companies that makes DeepSeek's hosted app a tool to block or tightly restrict for work, while teams that want DeepSeek models can run them through a provider or on infrastructure the company controls.

Why the usual approach falls short
Blocking one domain is easy. Knowing whether people use DeepSeek at all, stopping it consistently on every device, and offering the approved alternative in the same moment is what Maskflare adds.
The Maskflare approach
AI app discovery shows how often DeepSeek is used and by whom, without recording prompts. Its risk score reflects where the vendor is based and how it treats your data. Mark it blocked and every managed device refuses it, with your message naming the approved alternative; or tolerate it with strict masking while you decide. Teams that need DeepSeek models can use them through the Maskflare gateway with a provider you've approved, under the same masking rules.
