Perplexity security for business research

What Perplexity is

Perplexity answers questions by searching the web and summarizing results with citations. It offers free and paid individual plans and business offerings with administrative controls. The company has also introduced agentic browsing capabilities that can navigate sites and take actions for a user.

What Perplexity can access

• Queries — which frequently reveal strategy: acquisition targets, litigation research, product plans, or client names.
• Uploaded files for analysis alongside web results.
• Connected sources, where business plans support searching internal repositories alongside the web.
• Browsing sessions, when agentic features act within a user's browser, potentially including sites where the user is logged in.

Key risks

Sensitive context in queries

Research queries feel harmless, but a sequence of searches can reveal confidential intent. For law firms, investment teams, and corporate development, the query itself may be confidential information.

Unapproved individual accounts

Perplexity is often adopted individually and expensed. Without a business plan, the organization has no retention controls or visibility.

Agentic browsing and prompt injection

An AI that reads arbitrary web pages and can also act in logged-in sessions is the textbook prompt-injection scenario: a page can contain instructions that attempt to make the agent visit other sites, submit data, or reveal information from the session. Treat agentic browsers as privileged software and restrict them until you have reviewed their safeguards.

Source reliability

Citations make answers easier to verify, not automatically correct. Decisions should rely on the cited primary sources, not the summary.

Recommended controls

1. Decide whether Perplexity is approved; if so, standardize on an administered business plan with SSO.
2. Document the plan's retention and training terms in your vendor register.
3. State in policy that client names, deal names, and confidential matter details must not be used in queries on unapproved tools.
4. Restrict agentic browsing features, especially on devices with access to sensitive web applications.
5. Detect individual subscriptions through expense review.

How FlashTower assesses this

When you add Perplexity to a FlashTower Scan, the Risk Engine evaluates how it is actually used in your organization — account type, data accessed, capabilities, autonomy, credentials, logging, and vendor terms — against a versioned, deterministic ruleset. These rules are the most relevant for Perplexity. Each fires only when its stated condition is met. See how scoring works.
