Debian Firewall

Manage Debian Firewalls & Automate Security

Protect Your Debian Servers From Hackers & Vulnerabilities


Debian Firewall Security


The Debian firewall provides a terrific front-line defense for your server, but configuring it can be complex. Even the Debian security manual warns to be careful configuring your firewall, citing that it can, “easily be misused, causing enormous amounts of grief… It is not terribly uncommon for a remote system administrator to accidentally lock himself out of a system hundreds or thousands of miles away.” Fortunately Dome9 makes Debian server firewalling fast and easy!

Dome9 sets up in minutes and eliminates the threat of brute force attacks and exploits by closing otherwise open service ports like SSH and MySQL, opening them only on-demand for a specific user, service, and time period. This makes your Debian servers virtually invisible to hackers since closed firewall ports don’t respond to port scans and aren’t vulnerable to exploits and other attacks.
