How to use Perplexity safely

  • Use the business variant and sign a data processing agreement (DPA).
  • Do not enter unnecessary personal data into prompts; anonymise where possible.
  • Ask the provider explicitly where data is stored and processed.
  • Keep a professional in the loop: a security tool sees everything: log files, emails, usernames and network traffic.

Questions

How safe is Perplexity for cybersecurity?
The maker of Perplexity publishes little about data protection. Check this before you put confidential cybersecurity data into it. The provider publishes little on this, ask first before using it for business.
Does Perplexity train on my data?
Enterprise plans and the Sonar API are not trained on customer data (SOC 2 Type II; API with zero data retention). For consumer accounts, data use for model improvement can be switched off in the settings.
What should I watch out for with AI in cybersecurity?
A security tool sees everything: log files, emails, usernames and network traffic. That is personal data, so you need a data processing agreement and must know where the data is stored. Also ask whether the AI assistant is trained on your data. WithSecure (Finland) says it processes data for Luminen in AWS in Europe and does not train foundation models on customer data. Sekoia stores data in Germany or elsewhere in the EU/EEA and is ISO 27001 certified. SoSafe (France) can run self-hosted. With Microsoft Security Copilot you choose the geo of your workspace, but sharing data with Microsoft is on by default. For Charlotte AI, ESET LiveAI and Mindgard the hosting location is not public. Never let an agent act on production systems without analyst approval, and record who makes the 24-hour report under the Cybersecurity Act when an incident occurs.
