3Firewall & Ports

When managing employees devices in enterprise, privacy and security are main topics for the IT department due to multiple reasons. There are many strategies to keep both users and corporate data safe, and one of them is using proxies and firewalls to block malicious websites.

However, it’s critical that the IT administrators evaluate the proxies and firewalls that will be enabled carefully, since if the MDM servers and the devices are separated behind a firewall, they are unable to effectively communicate.
