Although UFW is a popular firewall management tool for Ubuntu servers, it still has many "gotchas" administrators have to learn the hard way. Compared to HeatShield, which offers built-in SSH brute force protection and the ability to centrally manage firewalls without using the command line, UFW leaves much to be desired.
Most server administrators using UFW have been bitten by the complication and confusion of rule ordering in UFW. HeatShield's rule system was designed to avoid the subtle confusions that can happen when using UFW, so you don't have to find out the hard way that a firewall rule isn't working like you expected.
Even if you're experienced with SSH, using HeatShield's browser-based management interface saves you time and hassle. You'll no longer have to fight with UFW's syntax when you can instead easily point and click to manage rules. If you're using many servers, not having to SSH in to each server to check and manage firewall rules not only makes your life easier but keeps you from making mistakes that happen when managing many servers manually.
Unlike UFW, HeatShield includes built-in monitoring for SSH brute force login attempts. Attacker addresses with repeated SSH login failres are automatically blocked by HeatShield. You don't have to waste your time and energy trying to integrate other software to do brute-force blocking.
As HeatShield is commercial software, we provide great support to our users. When you're running a business, getting support for the software you use can make a world of the difference.
