On-prem, air-gapped, compliant, and SLA-backed

On-prem and air-gapped deployments, dedicated capacity in your VPC, SOC 2 Type II, HIPAA, and the kind of paperwork regulated industries actually need. For teams whose retrieval requirements don't fit inside an off-the-shelf API contract.

When "Good Enough" Isn't Enough

Some teams need more than an API.

Most teams that use ZeroEntropy are fine with the managed API: sign up, paste a key, ship in minutes. But if your data can't leave your perimeter, your industry has paperwork, or you'd just rather have a direct line to the people who trained the model — you need something more. That's what Enterprise is for.

SOC 2
Type II

Audited annually. Reports and supporting controls available under NDA via the Trust Center.

HIPAA
compliant

BAAs signed routinely. PHI stays inside your perimeter on on-prem and AWS Marketplace deployments.
