Product preview

Overview

Vectara sells retrieval and agents to organisations that cannot send their documents to somebody else's cloud. The distinguishing feature is not the retrieval itself but where it runs: as a service, inside your own VPC, or air-gapped on premises, with governance and access control as part of the package.

That deployment range is the whole argument. For a bank, a hospital or a defence contractor, the choice is rarely between two retrieval engines on quality — it is between a system that can hold the data and one that cannot be deployed at all, and the shortlist is written by the constraint before the benchmark. What to check is therefore the boring part: whether the air-gapped option is genuinely complete or a reduced edition, what the update path looks like when the environment has no outbound network, and what the licensing and per-query economics are at your volume, none of which a product page settles.
