Netsilon 9: synchronise and secure your networks.

The security of critical systems is fundamental. In the event of an outage or malfunction, the consequences can be dramatic. This is why all the structures concerned must be equipped with a reliable and autonomous time server to synchronise their equipment with precision in case of an attack. This will limit the risk of intrusion and other cyber threats.

Netsilon 9: more features, more performance

Even more features, even more performance

Customisable. Depending on your needs and the constraints of your network installation, Netsilon 9 is able to adapt to transmit time information via a wide range of protocols. Its modular design with option cards enables a wide variety of input/output signals: 1PPS, IRIG, PTP, NTP, 10 MHz.
Secure. Encryptions, single sign-on system, activation/deactivation of network protocols: these are just some of the parameters available on Netsilon 9 that makes it a robust solution.
Durable. Literally and figuratively. On one hand, its fanless design ensures a longer service life. On the other hand, its low energy consumption means it uses less electricity and is therefore more respectful of the planet.

Netsilon 9: time accuracy for critical systems

The time precision that critical systems need

Many structures need a precise timekeeping. This is particularly the case in the energy and broadcasting sectors and connected industry 4.0. Thanks to its next-generation internal OCXO oscillator*, Netsilon 9 achieves micro-second accuracy to meet the network challenges of these sectors. All the information system’s equipment is synchronised via multi-source satellite reference signals: GPS, GLONASS, BeiDou, Galileo. With Netsilon 9, you can accurately trace all the events on your network. Which allows you to stay in control.

*High-precision oscillator requiring low power consumption.
