An expensive solution to monitor internet traffic with multiple dashboards

The huge library especially the open source link, makes it the main engine for Corelight with some enhancements in the commercial version. It has a very powerful level, such as signature-based attacks or behavioral attacks, with enhancements in the design. It is very flexible for intelligent implementations like IPs, especially between big companies and banks. Corelight is easy to understand and monitor what is going on behind the team. The solution is already integrated with other systems like Suricata, Elastic, and Microsoft tools. It's very easy to integrate signature-based or behavior-based engines. You can use Elastic for the dashboards to get it from Corelight, along with all the benefits and expandability.

Effectively monitors the uptime of all equipment and network connectivity

There is room for improvement on the setup side. It's not very user-friendly, especially for those who aren't tech-savvy. I find it a bit hard to set up initially. It could be done better to make it easier to configure. It would be beneficial for users. For additional features, I have an idea. I'm not sure if it's already there, but it would be great to have a feature that maps the network and shows which devices are connected. It could provide information about how traffic flows and offer a visual representation of how devices are physically connected to each other. It would be like a network audit feature that displays the connections between switches and other devices. So, in future releases, a network mapping and visualization feature would be valuable.
