Zendesk has announced the acquisition of Unleash, an AI-powered enterprise search platform designed to connect distributed knowledge across multiple systems and deliver reliable answers directly to the channels where employees work. Announced on December 18, 2025, this move targets a very specific goal: making internal support (IT, HR, operations) faster, cheaper, and more governable at a time when many organizations are already trying to “put a copilot” everywhere… and are discovering that the real problem is where the knowledge resides and who can see it.
The initiative aligns with a clear market trend: the shift from generic chatbots to “workflow AI” with context and controls. And here, Unleash provides three key components that, in practice, often determine whether an internal support AI initiative succeeds or is abandoned: unified search, permissioned RAG, and deep integration with corporate channels.
Exactly what Zendesk is buying: “enterprise search” + permissioned RAG
According to Zendesk itself, Unleash’s technology incorporates enterprise search and Retrieval-Augmented Generation (RAG) with permissions over more than 70 content sources, including typical knowledge repositories and documentation platforms like Google Drive, Confluence, or SharePoint. In product language: instead of an employee opening ten tabs and searching manually, the system can retrieve relevant information and compose a response using that material, but without bypassing access controls.
This detail — permissions — is more important than it sounds. In internal support, most failures aren’t because the model “doesn’t know,” but because:
- it returns information it shouldn’t (compliance risk),
- it omits correct information because it was siloed,
- or it generates a “nice” but unverified answer, which ultimately still requires escalation to a human.
Unleash’s approach, as described, focuses on applying fine-grained access controls at query time, which is crucial to prevent an assistant from responding with content the user isn’t authorized to see.
Native agents in Slack and Microsoft Teams: where the work truly happens
The second differentiator is the promise of native knowledge agents in Slack and Microsoft Teams, with built-in “handoff” and frictionless escalation to human experts. This isn’t just visual integration — it’s a change in interface.
In practice, internal support has moved to chat channels for years. People won’t “open a portal” if they can avoid it: they ask in a channel, tag someone, and wait for a response. If Zendesk can get AI to answer right there with context and permissions, it reduces the biggest operational costs: interruptions, downtime, and unnecessary tickets.
The concept of “AI within the workflow” is based on a simple principle: the less you force employees to switch tools, the higher the likelihood of real adoption. This accelerates what Zendesk calls “time to value”: visible results sooner and with less friction.
From internal support to a “single AI governance model” across the enterprise
Zendesk also suggests that this integration isn’t limited to Employee Service: the same set of capabilities (trustworthy AI, governance, workflows) can be extended to external support. From a strategic perspective, this unifies “how” AI is governed in customer service and internal support.
This makes sense in large organizations, where often something absurd happens: customer support has its automations, ITSM has others, HR operates through a different portal… and all try to build their own “assistant” separately. The result is duplication, costs, and a fragmented experience.
With Unleash, Zendesk aims to become the hub where case management, automation, and analytics converge with a unified, permission-controlled knowledge base.
The underlying message: less “chatbot,” more knowledge architecture
Beyond the announcement, the implicit message is that the future of internal support isn’t decided by having a “better” LLM, but by solving three classic problems:
- Connecting dispersed knowledge (and keeping it alive).
- Respecting permissions and policies without exceptions.
- Integrating into daily channels and escalating to humans without breaking flow.
The acquisition of Unleash addresses these three layers directly. If it delivers as promised, the value is twofold: fewer repetitive tickets and, more importantly, less “manual searching” (the unseen time that isn’t reflected in dashboards but drains productivity).
FAQs
What does “permissioned RAG” mean in internal support?
It means the system retrieves information from corporate sources to respond, but can only use and display content that the employee is authorized to see based on permissions.
Why is integration with Slack and Microsoft Teams important?
Because much of internal support already happens in chat. Responding there reduces friction, speeds resolution, and improves adoption compared to separate portals.
Does this replace internal support teams?
Not necessarily. The goal is to automate repetitive questions and accelerate resolutions, with smooth escalation to humans for complex or sensitive cases.
What types of sources does such an enterprise search typically connect to?
Document repositories and wikis (e.g., Drive, Confluence, SharePoint), ticketing tools, knowledge bases, and other operational documentation systems.
