We have developed very comprehensive, extremely scalable and intelligent enterprise network management and monitoring solution - Enigma NMS.

Enigma provides network professionals with complete view of entire network, server and application activity regardless of the size and complexity. Unlike other monitoring tools Enigma uses one server to monitor the entire network infrastructure and stores the data in its original granularity in its highly efficient industry standard MYSQL database. It is quite common to have a single Enigma server monitoring a global network of hundreds of thousands of interfaces every 60 seconds. Data collected by Enigma is stored for up to 12 months with no roll up or averaging. Enigma will be your main source of network truth, which you can rely upon in your operational and business decisions.
Enigma built-in, automatic and pro-active data analytics allow effective extraction of the most important information from the vast amount of network data exposing areas, which need immediate attention or suffer from performance bottlenecks.
