Three assistants, one view

Copilot is available today, Claude Enterprise is in preview and ChatGPT Enterprise is coming soon. One Microsoft Entra ID identity joins all three, so seats, spend and access read by department.

The problem

Where AI assistants go wrong on your data

AI assistants follow the rules you already have. They read at the access you grant and answer from the content they find, so their risks are your own data and permission gaps, made instantly visible.

  1. Every assistant inherits your oversharing

    Copilot reads at the permissions your tenant already grants, and a SharePoint site connected to a Claude Enterprise (preview) or ChatGPT Enterprise (coming soon) project reaches everyone that project is shared with. One overshared site becomes an answer for the whole workforce.

  2. Sensitive content with no label

    Unlabeled documents look the same as public ones to Copilot, so confidential material can surface in a prompt.

  3. Stale content, confident answers

    No assistant can tell current from outdated, so retired policies and old figures come back as fact, in Copilot and in every project a stale site is connected to.

  4. Seats spent, value unproven

    Copilot licenses, Claude Enterprise (preview) seats and ChatGPT Enterprise (coming soon) seats get assigned and forgotten, sometimes to the same person twice, with no view of who uses which assistant or what it returns.

How Rencore gets AI assistants under control

Start with Copilot, where coverage is deepest, and apply the same discipline to Claude Enterprise (preview) and ChatGPT Enterprise (coming soon, preview from October 15, 2026), both included in the AI & Agents module. See what each assistant can reach, rank the exposure by risk, then fix it and prove readiness. Rencore complements Microsoft Purview and Entra; it does not replace them.

See exactly what each assistant can reach

Map the sites, Teams and files Copilot can pull into an answer, and surface the unlabeled content first, before anyone prompts for it or connects the same site to a Claude Enterprise (preview) or ChatGPT Enterprise (coming soon) project.

See how it works

Rank

Stop oversharing before any assistant surfaces it

Rank exposure by risk: anonymous links, external shares with no expiry and broken inheritance, so you close what Copilot would surface first.

Take a finance SharePoint site with an anyone link. Copilot can already reach it, and when someone wires the same site into a ChatGPT Enterprise (coming soon) project, everyone that project is shared with can reach it too. Rencore shows the site’s sharing next to the project’s connector scope and the people it is shared with, so you close the link once for every assistant. In Claude Enterprise (preview), Rencore shows which projects are visible to the whole organization and who collaborates on them.

See how it works

Fix

Right-size the permissions every assistant inherits

See which apps and accounts hold standing access to Microsoft 365 data, and tighten the ones the assistants ride on: the Copilot connectors, and the Microsoft 365 connector apps that Claude Enterprise (preview) and ChatGPT Enterprise (coming soon) register in Entra ID.

See how it works

Prove

Prove AI readiness and control the spend

Track Copilot usage and license cost by department, so you enable the seats that return value and reclaim the ones that do not. Next to it, see Claude Enterprise (preview) seats, adoption and token cost per user and department against the spend limits you set, and, with ChatGPT Enterprise (coming soon), the people who hold both a ChatGPT Enterprise seat and a Copilot license.

Common questions on this

What is AI assistant governance?
AI assistant governance is the practice of controlling what your AI assistants can reach and surface: which sites, files and Teams Microsoft 365 Copilot can read, which SharePoint sites are connected to Claude Enterprise (preview) or ChatGPT Enterprise (coming soon) projects and who those projects are shared with, which connector apps hold standing access, and what each assistant costs per department. Every assistant answers at the access it is given, so the work is right-sizing that access and the data beneath it. For Copilot alone, see Govern Copilot.
How is this different from Rencore’s AI agent governance page?
This page is about AI assistants, Microsoft 365 Copilot, Claude Enterprise (preview) and ChatGPT Enterprise (coming soon), and the data they can reach. AI agent governance covers the wider estate: the Copilot Studio agents, SharePoint agents and other AI agents people build, which multiply outside any inventory. If your question is agent sprawl and shadow AI, start with AI agent governance; if it is what your assistants surface from your own data, you are on the right page.
Does Rencore replace Microsoft Purview or Entra for Copilot?
No. Rencore complements Microsoft’s own controls. Purview labels and protects data and Entra manages identity and access; Rencore inventories what Copilot can reach across the estate, ranks the exposure by risk and routes the fixes to owners, so those Microsoft controls get applied where they matter before Copilot surfaces the gap.
Does this cover Claude Enterprise and ChatGPT Enterprise?
Yes, both are included in the AI & Agents module, with Microsoft 365 Copilot as the deepest coverage. Claude Enterprise is in preview: Rencore joins each user to their Entra ID department and country and shows projects, their visibility and collaborators, seats, token cost and spend limits. ChatGPT Enterprise is coming soon, with a preview from October 15, 2026, covering custom GPTs, projects and the connectors wired into them. Copilot, generally available, has its own page: Govern Copilot. Both read metadata only, on Enterprise plans, and neither replaces the controls OpenAI and Anthropic provide.
Can we assess Copilot exposure before we roll it out?
Yes. You can see what Copilot would reach on day one: overshared sites, unlabeled sensitive content and stale documents, ranked by risk, alongside license cost by department so you enable the seats that return value. See Microsoft Copilot readiness for the full pre-rollout checklist.
