Firewall

A firewall controls which traffic can enter and leave your network. A hardware firewall protects every device in the office at once, before threats reach the computers.

No. A VPN encrypts the connection between two points, while a firewall filters traffic. Business firewalls such as Zyxel UTM models include both firewall and VPN features.

For small and medium businesses a UTM firewall with security services, such as Zyxel with the Gold Security Pack, or a UniFi Cloud Gateway offers strong protection with easy cloud management.

Always keep it on. A firewall is one of the basic layers of protection for any network and computer.
