CybersecurityPerplexity for cybersecurity
US AI search engine that delivers answers with source citations via its own Sonar models and external frontier models, with separate Enterprise agreements on data use.
Perplexity is not on our list for cybersecurity. Usable for general work, but first look at the options we recommend for cybersecurity.
- GDPR profileOur summary of what the provider itself publishes about your data: EU hosting possible, no training on your data for business use, and self-hosting available. Caution applies to a model with a documented problem, such as an investigation by a regulator. How we measure
- GDPR: Unknown
- QualityQuality from blind duels on LMArena: users choose between two anonymous answers. A difference of about 20 points is noticeable, a few points is noise. How we measure
- –Elo, independent
- Editorial scoreOur own assessment on 10 of suitability for professional work, price and privacy. This is a judgement, not a measurement; that is why it always sits alongside the Elo. How we measure

What Perplexity does in cybersecurity
- Detection and triage: assessing, grouping and summarising alerts from endpoints, network, cloud and email
- Investigation and response: working out incidents, writing queries and proposing or carrying out countermeasures
- Attack surface and pentests: mapping reachable systems and testing vulnerabilities with AI agents
- Awareness and reporting: phishing simulations, staff training and reports for NIS2 and the board
- Answers with source citations based on live web information
- Access to multiple frontier models within one subscription
- Deep Research and Labs for in-depth reports
- Enterprise: SOC 2 Type II, no training on business data
The maker of Perplexity publishes little about data protection. Ask about this before you put confidential cybersecurity data into it.
Confidentiality and GDPR
GDPR: UnknownA 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.
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.
