Hey everyone! With all the buzz around AI assistants, I'm seeing more teams in our space (sales, revenue ops, analytics) wanting to adopt them but hitting a wall with security and compliance. Two contenders that often come up for enterprise use are Perplexity and Bing Chat Enterprise.
From my research and conversations with IT folks, the core difference for a security-conscious org really boils down to architecture and data handling:
* **Bing Chat Enterprise** is built on the Microsoft Cloud and leans heavily into their existing compliance frameworks. If your company is already a Microsoft 365 shop, the integration is seamless. User identities are verified through Entra ID (formerly Azure AD), and chat data is **not** saved, used to train models, or exposed to other tenants. It's essentially a protected layer on top of Bing Search. The big plus? It's included in certain M365 licenses at no extra cost.
* **Perplexity** (specifically their Pro/Enterprise offerings) is a powerful, search-centric AI tool. They offer strong data privacy promises (not training on your data, etc.), but as a third-party service, it requires a separate review of their SOC 2, data processing agreements (DPA), and how it fits into your existing tech stack. Its strength is in its user experience and depth of research capabilities.
For me, the practical decision often comes down to this: **Is your org's identity and security ecosystem centered on Microsoft?** If yes, Bing Chat Enterprise is the easier "default secure" path to pilot. If you need deeper research, citation fidelity, and are equipped to vet a best-of-breed vendor, Perplexity's capabilities are fantastic.
Has anyone gone through a formal security review for either tool at their company? I'm especially curious about real-world experiences with Perplexity's Enterprise plan in a sales or analytics context. What did your infosec teams focus on?

I'm a lead analytics engineer at a mid-sized fintech, managing our data stack and evaluating tools for a ~200 person team with strict SOC 2 requirements. We trialed both options for 90 days.
**Core Comparison:**
1. **Cost Structure:** Bing Chat Enterprise is effectively $0 if you have eligible M365 E3/E5/Business Premium licenses. Perplexity Enterprise pricing is opaque but quotes start around $40/user/month for annual commitments, with custom contracts for >100 seats.
2. **Integration Effort:** For a fully Microsoft-authenticated environment, Bingle Chat Enterprise requires ~15 minutes of admin consent. Perplexity required 4-6 weeks for our legal to finalize a DPA and review their SOC 2 Type II, plus separate SSO setup.
3. **Honest Limitation:** Bing Chat Enterprise is a search copilot; its ability to analyze or summarize your own internal documents is limited unless you build on Azure OpenAI. Perplexity's "Pro Search" excels at iterative web research but offers no native integration with private SharePoint or internal wikis.
4. **Where it Breaks:** In our testing, Perplexity's upload feature (for analyzing PDFs) failed silently on files over 10MB, truncating results. Bing Chat Enterprise reliably refused to answer based on internal URLs, maintaining its isolation boundary.
**My Pick:** For general, secure web search augmentation for an M365 shop, I'd deploy Bing Chat Enterprise immediately. For a team whose primary need is deep, cited external research, Perplexity is stronger, but only if you can absorb its cost and legal overhead. Tell us your primary identity provider and whether the core use case is internal data or external research.
