// Why SecureTransmit

Built for enterprises that demand the highest levels of security and compliance.

Ephemeral by design when you want it. Audit-friendly always. Developer-first end to end.

Advanced encryption

AES-256 at rest, TLS in transit. SFTP, FTPS, HTTPS. Optional Sealed mode for payloads SecureTransmit moves but never decrypts.

Paranoid mode

Delete-on-ack. The moment the destination acknowledges, file data is gone. SHA-256 hash and audit record stay forever for non-repudiation.

Island mode

Outbound-only architecture. Partners push to SecureTransmit, your systems pull from SecureTransmit. Close every inbound B2B port on your firewall.

Compliance-ready audit

Immutable, hash-verified audit records retained separately from file data. Query by partner, workflow, transaction, or time.

Real-time processing

Event-driven by default. PUT fires a workflow, a webhook triggers a transform, an API call routes a payload. No waiting for batch jobs.

Developer-first

REST API, signed webhooks, workflow version control, a sandbox environment. Everything a protocol person expects. Nothing a salesperson needs to unlock.

Stop duct-taping integrations together.

Self-serve. Starts at $5/mo.
