## What is Proactive Defense and how do I enable and disable it?
Proactive Defense protects websites running PHP against zero-day attacks by blocking potentially malicious executions automatically and with zero latency. Proactive Defense is enabled by default. It adds an additional layer of security to your website by blocking PHP scripts that contain code that could hurt your website or visitors. Proactive Defence has three modes:
* **Disabled**: This means that the Proactive Defense feature is not working and the system is unprotected. Data is logged in all modes except Disabled.
* **Log Only**: This means that possible malicious activity is only logged, and no actions are performed. **This is the default mode.**
* **Kill Mode**: This is the highest level of protection. Scripts are terminated as soon as malicious activity is detected.
**Important**
For security reasons, we highly recommend that Proactive Defense is left in Kill Mode. Please exercise extreme caution when disabling Proactive Defense.
To disable or enable Proactive Defense, follow these steps:
1. Log in to cPanel.
