Proactive Defense

What is Proactive Defense? 


Proactive Defense is our unique technology that detects and blocks malicious execution flow in runtime. When enabled – it analyzes the PHP script behavior and either blocks the entire script execution or just stops the malicious flow. This is crucially important because malicious code is often hidden: obfuscated, injected in the middle of the legitimate file, fetched from the network dynamically, or placed in the database. Proactive Defense detects malicious code when it is executed and stops it before it causes any damage to the server, therefore supporting a concept of Proactive Security – preventing the incidents from happening in the first place rather than dealing with the consequences of a viral attack.
