Easy UI with which you can access all your servers as well as their configurations.Easy interface for end users too who want more control over server configuration etc.
Lack of support from third party vendors like Kaspersky Endpoint Security (KES). I would recommend this product if you are looking out for easy management system but also have some sort of security features integrated into them along side monitoring capabilities. We need an efficient way to manage our network devices especially switches & routers seamlessly so we dont have to switch back-and forth between two apps.
