Key Features
- Security Level: Set the level of protection based on IP reputation:
- Low, Medium, High – Adjust the strictness of security challenges.
- I’m Under Attack! – Use this mode during active attacks to safeguard your site.
- Challenge Time: Define the duration for which a visitor’s IP will remain challenged before being allowed access:
- Browser Check: This verifies that website visitors use legitimate browsers, blocking suspicious traffic from bots and automated attacks before they reach your site.
- Web Application Firewall: Protects your web applications from threats like SQL injection and cross-site scripting (XSS) by filtering and blocking malicious traffic using customizable security rules.
- IP Firewall: Control access to your site under three modes:
- Block: Blocking specific IP addresses or ranges.
- Challenge: The site presents a CAPTCHA to visitors from specific IPs to verify that they're legitimate users. If they pass, they access the site; otherwise, they're blocked. This helps protect against suspicious traffic and bots.
- Whitelist: Allowing specific IP addresses or ranges.
