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.
