ShieldSquare Feed-Based Protection | Active Mode


ShieldSquare Feed-Based Protection provides a mechanism to take action on bots at the IP Level without the need to make a Synchronous API call to ShieldSquare Service. Feed-Based Protection comes in very handy when the complete web page content is cached at the CDN level, and requests don’t reach the server layer before being rendered. Feed-Based Protection can be consumed at the application level, server level, WAF level, or CDN level depending on your needs.

The documentation below explains ShieldSquare's bot blocking procedure by consuming Feed-Based Protection, encompassing prerequisites, Service description, response formats, and the implementation process.


  1. Blacklisted signatures: These are the signatures that have bot characteristics and have been detected by ShieldSquare.
  2. Deleted signatures: Every signature blocked has an expiration time. Throughout the document, a deleted signature refers to the expired signature.
  3. Cron Job: The software utility Cron is a time-based job-scheduler in Unix-type computer Operating Systems like UNIX, Linux, FreeBSD and Darwin (Mac OS X). People who set up and maintain software environments use cron to schedule jobs to run periodically at fixed times, dates, or intervals.
  4. JSON: JavaScript Object Notation is an open standard format that uses human-readable text to transmit data objects consisting of attribute–value pairs.
  5. IP Feed: This has been interchangeably used with ‘Feed’ and ‘ShieldSquare IP Feed’.
