nChronos is a network performance analysis solution for high performance & critical enterprise networks. It combines the nChronos Console with the nChronos Server to deliver the capability of 24x7 continuous packet capturing, unlimited data storage, efficient data mining and in depth traffic analysis solution. nChronos doesn't rely on SNMP or Netflow but captures 100% of all data captured for real-time analysis as well as historical playback.
nChronos can not only alert an Cyber Attack, but also record all packet data. This ability helps network engineers to "rewind" and "replay" the actual network activity when it occurs. Companies have video cameras to monitor who physically enters their business afterhours, now with nChronos network engineers can monitor and record data activity in a similar manner. The time has come where theft of company assets and intellectual property from data streams and network activity is the greater threat. With a relatively minor investment, nChronos provides an insight and deep packet analysis of all network activity.
