6. 5 Security and Compliance Principles for Using DeepSeek at Work
When using the DeepSeek AI assistant in a corporate environment, always follow these rules:
- Do not upload confidential data: Business contract IDs, customer privacy, unreleased financial data, passwords, and keys should not be entered
- Human review required for AI output: Especially for external emails, legal text, and data conclusions
- Follow company IT policy: Confirm whether external DeepSeek online use services are permitted
- Disclose AI assistance: If internal documents heavily rely on AI-generated content, annotate per company policy
- Separate sessions: Do not mix Client A and Client B information in the same conversation
The goal of DeepSeek office use is efficiency—not replacing compliance processes.
7. 6 Common Workplace Mistakes
| Mistake | Correct Approach |
|---|---|
| Vague prompts: “Help me write a proposal” | Specify audience, format, word count, constraints |
| Using Pro for every task | Use Flash for daily quick edits to save time |
| Stuffing 10 requirements in one message | Split into multiple DeepSeek conversation rounds |
| Forwarding without verifying data | Numbers, dates, and names must be manually checked |
| Never starting a new window in long chats | After 20+ turns, start a new session to maintain speed |
| Only chatting without saving templates | Build a personal “office template library” for common prompts |
