Sucuri

What is Sucuri?

About

Sucuri crawls websites to detect malware, security vulnerabilities, and blacklist status as part of its cloud-based website security platform and malware removal services. You can see how often Sucuri visits your website by setting up Dark Visitors agent analytics.

Expected Behavior

Security scanners do not follow a predictable schedule when visiting websites. Their scans can be one-time, occasional, or recurring depending on the purpose of the scanner and the organization's security practices. The frequency and depth of their scans can vary based on factors like the visibility of the site on the public internet, past scan results, and inclusion in external threat intelligence feeds.

Should I Block Sucuri?

Probably not. Security scanners can be beneficial, especially if they're configured to report issues back to you.

How Do I Block Sucuri?

⚠️ Manual Robots.txt Edits Are Not Scalable
New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.

You can block Sucuri or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
