Used for troubleshooting and receiving real-time alerts and works on artificial intelligence
I always recommend Marvis to every customer because it requires no additional direct involvement. Marvis has been developed well using AI and machine learning technology. Its AI engine updates itself regularly, which is a beneficial feature. I request that Juniper integrate a cloud identity engine and simplify the Microsoft Azure Active Directory Services integration with the SRX hardware firewall. Additionally, the SRX firewall needs a more robust graphical user interface. Currently, we can only configure the SRX using the CLI; if a wrong command is entered, restoring it cannot be easy. Overall, I rate the solution a nine out of ten.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.
