Purview installs on every endpoint. Trinito doesn't touch your endpoints.

Microsoft Purview is a strong answer inside Microsoft 365. Trinito is built for the question your staff are already asking: can we use ChatGPT without leaking client data?

Three reasons teams look at Trinito

  1. No endpoint agent. Trinito installs nothing on staff Macs, PCs, phones, or tablets. No Intune rollout, no per-seat agent licence, no visibility gap when someone buys a new laptop.
  2. Bring your own LLM keys. OpenAI, Anthropic, Google, Ollama Cloud, or a local model on the box — the customer chooses and uses their own accounts. Redacted prompts go direct from the appliance to the provider.
  3. UK SMB plug-and-play. Buy the appliance, plug it in, create user accounts, staff use the Trinito chat. No Microsoft admin console expertise required for the basic deployment.

Who has Purview AI features

M365 plan (typical SMB)Purview AI / third-party LLM DLP
Business Basic / StandardNot included — upgrade or add-on required
Business PremiumAvailable as paid add-on (not in base price)
E3Add-on for advanced AI DLP features
E5Included — the plan Purview marketing assumes

If you are not on E5 (or have not bought the add-on), Purview's AI story is not something you can switch on tomorrow.

These products do different jobs

Purview is a data loss prevention layer for the Microsoft 365 surface. If your concern is stopping client lists leaving via Outlook or Teams, Purview is built for that — integrated with everything Microsoft.

Trinito is a redaction layer for AI prompts. If your concern is staff pasting client data into ChatGPT or legal won't let you send PII to Claude, Trinito is built for that — no Microsoft licensing required, works with whichever AI provider you choose.

Many customers benefit from both. Trinito does not replace Purview's email and SharePoint coverage; Purview does not redact prompts before they reach the LLM provider.

When Purview is the right answer

You are already on E5, standardised on Edge for Business, Entra ID everywhere, and your AI risk is mostly Copilot inside M365. Purview extends what you already bought.

When Trinito is the right answer

You are on Business Standard or below, use mixed browsers and phones, run Google Workspace or Mac-heavy, need on-prem audit logs, or want frontier LLMs with UK-side inspection without an E5 uplift. See also vs SaaS prompt-firewalls.
