Either you are using Ubuntu or CentOS, you’ll always need to setup firewall for basic server security. But sometimes using command lines can be difficult if you are a beginner.
If that’s the case, here’s HeatShield.
What can HeatShield do?
- Prevent brute force attacks on SSH port
- Automatic firewall setups for SSH, HTTP, HTTPS ports
- Custom firewall support (paid plan only)
- Manage unlimited servers
HeatShield can be used on both 32/64bit Ubuntu 12.04+、Debian 6+、RHEL/CentOS 5+、Fedora 18+ servers.
Paid plan costs $10/per server per month.
If there’s no need to manually assign custom ports, then free plan is fine.
