If a security patch is released, but you can’t update your site, it becomes an easy target for hackers. We constantly update patches and server rules to protect your site.

Machine Learning

Machine Learning

Protect your website from emerging security threats. We correlate attack data across our network to better understand malicious behavior and keep your site secure.

Protected Pages

Protected Pages

Add another layer of protection to sensitive pages by enabling the Protected Page feature. Add passwords, CAPTCHA, 2FA (via Google Authenticator), or IP allowlisting.

IP Allowlisting

IP Allowlisting

Allowlisted IP addresses ensure that only your team can access website administrative areas. Restrict your admin panels so malicious users don’t gain access.

Application Profiling

Application Profiling

Each site has its CMS, server software, and other technologies in the stack. We analyze all the traffic to block requests that don’t fit your web application’s profile.

Signature Detection

Signature Detection

All HTTP/HTTPS web traffic is inspected before reaching your server. With heuristic and signature-based techniques, we block malicious requests and attack patterns.

Bad Bot Blocking

Bad Bot Blocking

When our systems detect a malicious bot or hacker tool trying to attack your site, it is blocked automatically. We protect your site from vulnerability exploitation attempts.

Geo Blocking

Geo Blocking

Most website attacks come from only a handful of countries. Block all visitors from the top three attack countries with one click or choose which countries to block.

How to Activate Intrusion Detection System (IDS) and DDoS Protection

1.

Add Your Site to the Sucuri Firewall
