Everything is automated

Wide range of actions, flexible thresholds and custom scripting when your imagination is even wilder than ours.


All communications are encrypted with AES265 and authenticated. Access control down to the specific metric.

Flexible data collection

Everything is a datasource – SNMP, NetXMS agent, your application of a script. Once collected, filter or convert values before they are processed further.

NetXMS is a platform

It's not just a network monitoring and management NetXMS is our foundation for ATM, payment switches, and industrial plants monitoring.


It does not matter how complex your network is – with NetXMS can always find a way. NAT penetration as well as proxy for SNMP, ICMP, and native protocol.

Remote management

Send SNMP SET commands, run applications remotely, transfer files (even in bulk) or just take a screenshot to see how system operates (if there is a screen).
