Zero external infrastructure
No servers, no 24/7 services. A standalone binary that runs in the background.
Solution
Kontext Secure Transfer
The file that provably arrived, encrypted and with a receipt — so no partner can ever say 'we never got it'. End-to-end transfer, behind your firewall, without opening a single port.
What it is
Overview
In B2B exchange, the most expensive argument starts with “we never received that file.” With no receipt and no log, the burden of proof is yours — and right behind it comes the chargeback or the rejected ASN. Kontext Secure Transfer moves your critical data with bank-grade security and leaves a trail for every send: every transfer is logged, encrypted end to end over SFTP/FTPS, running behind your firewall without touching your security policies.
AES-256 encryption for data in transit and local configuration, cross-platform, with no open ports and no exposed infrastructure. The transfer nobody remembers exists — because it never fails.
