“Enterprise AI search” can mean searching across your tools, researching the web, or querying your own documents — different problems with different tools. Here’s a fair 2026 comparison for UK businesses. (dgm implements osFoundry as an independent partner; we’ll be honest about fit.)
Three different problems
| Need | Best tool |
|---|---|
| Search across many tools | Glean (dedicated enterprise search) |
| AI web research | Perplexity Enterprise |
| Query your own documents (RAG) | osFoundry (within a platform) |
Dedicated enterprise search
Glean is purpose-built for cross-tool enterprise search — 100+ connectors, an Enterprise Graph, permissions-aware. If your problem is “we can’t find anything across dozens of tools”, Glean fits. (See osFoundry vs Glean.)
Web research
Perplexity Enterprise is the research and answer engine — web search with citations, deep research. For external research, it leads. (See osFoundry vs Perplexity Enterprise.)
RAG over your own data
Retrieval-augmented generation (RAG) retrieves from your own documents to ground AI answers — often a capability within a broader AI platform rather than a standalone search product. osFoundry offers RAG-class retrieval and a knowledge base, so search over your own knowledge sits within the platform you also use for chat, agents and apps. (See RAG explained.)
Search vs the root cause
A strategic note: dedicated search (Glean) sits on top of a sprawling tool estate; a consolidating platform (osFoundry) reduces the sprawl itself. If your real problem is tool sprawl, consolidation may address the root cause. (See how to cut SaaS costs with AI.)
Data security and UK control
Good AI search is permissions-aware — it respects who can see what. For UK data control, favour EU residency or self-hosting and no training on your data. Glean offers EMEA residency; osFoundry offers an EU region or self-hosting. Verify each vendor.
Where osFoundry fits
For retrieval over your own documents within a broader platform with data control, osFoundry fits. For dedicated cross-tool search, we’d point you to Glean; for web research, Perplexity.
