network monitoring tool and application scanning tool for on premise
We have application servers hosted on-premise, the servers are behind the firewall. users who access the application server from external network have to pass though the VPN network. I am looking for the network monitoring tool and also vulnerable scanning tool for web application server. I found following New Relic network monitoring tool and Qualys Security solution but these are cloud based. Please suggest for on premise deployment and suggestions please.
Thanks in advance.
