We build, operate, and maintain our own time infrastructure. VNTP is a custom NTP solution based on Chrony, with multiple independent sources. Every server and service we run synchronises against it. No public NTP pools. No third-party time.
VNTP is deployed as a small, dedicated time service on your network. Chrony handles synchronisation across multiple independent upstream sources, and every client system queries the internal service only — never the public internet. In air-gapped environments, VNTP is the authoritative time source on the network.
Multiple independent sources, disciplined by Chrony. Sub-millisecond accuracy across your entire estate — logs, certificates, and replication all agree on the clock.
No public NTP dependence. Inside isolated networks, VNTP is the only time source — nothing leaves, nothing leaks, everything stays in sync.
The synchronisation engine. Disciplines all sources, serves clients on the internal network, survives upstream loss without drift.
We partner with vendors around the world for Stratum-0 reference clocks. Full physical isolation is supported — the reference clock is deployed on-site. Stratum-1 is just a VM on your cluster.
GPS and pulse-per-second disciplined clocks for environments that need hardware-level precision and offline autonomy.
Client systems never talk to public NTP. All time flows through the internal service. Your estate has one clock.
