Voice AI for Regulated Enterprises

Banks, insurers, healthcare organizations, and government agencies can't send voice data to someone else's cloud. Voicegain runs entirely in your environment — on-prem, in your VPC, or fully air-gapped — with nothing leaving your perimeter.

The challenge

Voice AI shouldn't force you to surrender your data.

100%

of audio, transcripts, and models stay inside your infrastructure — nothing is sent to a third-party cloud for processing

0

external API calls required — the full speech stack, including models, runs where your security team can audit it.

PII

redaction built in — names, card numbers, SSNs, and health information scrubbed from transcripts before they're stored.

Most voice AI vendors are cloud-only — a non-starter when regulators, auditors, or your own security policies require data to stay inside your perimeter. Voicegain was built for exactly this constraint: the same models and APIs, deployed as software in your datacenter, your VPC, or an air-gapped network.

Three paths forward

How Voicegain fits your compliance posture.

From a ready-made agent running inside your walls to raw APIs on air-gapped hardware — every path keeps your data where it belongs.
