Features for Free Plan Servers

For servers on the free plan, HeatShield configures a firewall with the following traffic allowed to your server.

To                       Action      From
--                       ------      ----
22/tcp    SSH            ALLOW       Anywhere
80/tcp    HTTP           ALLOW       Anywhere
443/tcp   HTTPS          ALLOW       Anywhere

All other traffic to your server is blocked.

SSH Brute Force Protection

By default, HeatShield offers SSH brute force protection by dynamically updating your servers' firewalls to block IP addresses that have attempted malicious SSH login attacks on any of your servers.
