Move files at blazing speed with machine learning optimization and end-to-end encryption. Cloud, peer-to-peer, or automated sync — Keryx adapts to your workflow.
High-performance file transfer, built by security experts
Keryx is built by NetViper. We build tools that make secure file transfer fast and accessible for everyone — from individual developers to enterprise teams.
We believe fast file transfer shouldn't come at the cost of security. Keryx was built from the ground up in Rust to deliver both — maximum speed with end-to-end encryption by default. No compromises.
Keryx uses machine learning to optimize every transfer automatically. Our contextual bandit algorithm learns your network conditions and tunes parameters in real time — chunk sizes, parallelism, buffer sizes, and route selection. The result: transfers that are up to 11.2x faster than traditional tools like SCP, with 97.6% line utilization on gigabit connections.
