Real Time Block Lists

Website Firewall HAF
Spam Master blocks malicious activity before it even reaches your website or admin pages. Spam Master implements a new concept called High Availability Firewall that protects your website against dangerous exploits like HTTP and HTTPS DDoS (denial-of-service), SQL injections, brute force attacks and many others threats.
Buffer technology greatly reduces server resources like cpu, memory and bandwidth by doing fast local machine checks. Also prevents major attacks like flooding, DoS , etc. via Spam Master Firewall.
Spam Buffer Whitelisting excludes spam checks from safe Emails or Ip’s, it also removes these safe Emails and Ip’s from your local Spam Buffer.
Administrator Pages Protection
Spam Master blocks DOS resulting from brute force attacks or sql injections trying to login or search for admin passwords.
