Protect it with the 1&1 external firewall, the server’s first line of defense.

Stop hackers in their tracks

As the Internet has grown, so has the all-too-real threat of online attacks. Hackers, viruses and Distributed Denial of Service (DDoS) attacks can cripple or damage your server. 1&1 Firewall is an external barrier that filters traffic before it even reaches your server, so your data stays safe.

The power of Cisco

Data security doesn’t have to be a compromise. 1&1 Firewall is based on technology from Cisco Systems, one of the most reputable names in network security, so your 1&1 server will have advanced protection from a trusted industry leader.

Easy setup

Included with all 1&1 Server packages at no charge, 1&1 Firewall can be turned on/off and fully configured right from your Control Panel. There’s no extra software needed.
