Perplexity can be used at work only under specific conditions. Our verdict for a typical 50–500 person company handling client or regulated data: Limited. Excellent for research on public topics; personal accounts may feed queries back into training, and search queries themselves can leak strategy. The subtle leak is the query itself: "acquisition targets in [niche] under $20M" typed into a consumer account is confidential strategy leaving the building.

| Our tier verdict | Limited — Excellent for research on public topics; personal accounts may feed queries back into training, and search queries themselves can leak strategy. |
| Trains on your data? | Depends on plan / settings. Perplexity’s consumer terms permit using queries to improve the service, with an opt-out; its Enterprise Pro tier is marketed as excluding customer data from training. |
| Data retention | Search history is retained per account settings; enterprise tiers add organizational control. |
| Admin controls | Enterprise Pro adds user management and SSO; personal accounts have none. |
| Compliance certifications | SOC 2 Type 2 advertised for Enterprise Pro (per Perplexity’s published materials) |
| HIPAA / BAA | Not publicly documented. |
Perplexity’s consumer terms permit using queries to improve the service, with an opt-out; its Enterprise Pro tier is marketed as excluding customer data from training.
Retention: Search history is retained per account settings; enterprise tiers add organizational control.
Not publicly documented. As a rule: no signed Business Associate Agreement means no protected health information (PHI) — regardless of how good the vendor’s general security posture is.
HIPAA is the gate: Not publicly documented. Until a BAA is confirmed in writing, treat Perplexity as off-limits for anything containing PHI — patient names, appointment details, clinical notes, even "anonymized" summaries that could be re-identified.
For SEC/FINRA-regulated firms the questions are recordkeeping and confidentiality: can communications through Perplexity be captured for books-and-records requirements, and do the data terms hold up in vendor due diligence? Enterprise Pro adds user management and SSO; personal accounts have none.
The privilege question comes first: entering client-confidential facts into any third-party AI service must be evaluated as a potential disclosure. Because training/retention on Perplexity depends on account type and settings, assume client matter data is off-limits unless your firm controls the account and has verified the terms.
Why the tier verdict is "generic": Limited is the right starting classification for most 50–500 person companies — but a healthcare company, a law firm, and a SaaS startup should not have identical tool lists. The $79 policy kit classifies Perplexity and 24+ other tools specifically for your industry, company size, and the data your team handles.
And it goes stale: vendor data policies change quietly — a terms update can move a tool between tiers overnight. The $149/mo Monitor plan exists precisely because this page is only accurate as of July 2026.
