6.0.0 

February, 2026

GENERAL

  • NetVizura has been upgraded from Elasticsearch 7 to Elasticsearch 8, bringing improved performance, stability, and scalability for data analysis

NETFLOW ANALYZER

  • We are proud to introduce the new and improved Raw Data module. Raw flow records are now stored and queried from Elasticsearch indices, delivering significantly improved performance, scalability, and responsiveness when working with large datasets. The module now offers enhanced filtering, sorting, grouping, and bidirectional flow analysis, complemented by interactive traffic timeline charts and additional columns that expose richer flow attributes and provide deeper visibility. All existing capabilities—such as WhoIs lookups, IP/port resolution, and CSV export—remain available, now fully powered by Elasticsearch queries. Learn all about the new Raw Data on the following page Raw Data Forensics ElasticSearch
  • Besides Syslog messages, now you can store NetFlow data as well locally or on the remote Elastic server. How to set up remote Elasticsearch step by step we have covered here Configuring Elastic Server
  • Minor bug fixes were made

EVENTLOG ANALYZER

  • Minor bug fixes were made

Henceforth you can monitor your traffic near real-time. Set up your desired data aggregation interval by following instructions on the page Data aggregation interval
  • Elasticsearch database becomes the main database. To learn more about its strengths and benefits, visit Elasticsearch
  • We have developed the Migration tool, an instrument for the swift transfer of data from PostgreSQL to Elasticsearch. Find out more on the following page NetVizura Data Migration
  • Charts and tables offer the functionalities you already use, however, they are now more modern, visually appealing and interactive

Data migration is only required if you are using previous versions of NetVizura (NetVizura 4.7.4 and older). Once you complete data migration, it is not possible to migrate data back to NetVizura 4.x version.
