The scraper gap

Tell real readers from scrapers that look like them

Your CDN and WAF are built for DDoS and known crawlers. A sophisticated crawler that runs a real browser and behaves like a reader slips past them. Centinel closes that gap.

How the layers fit together

Your CDN and WAF

  • Absorb DDoS attacks
  • Block known crawlers and bots
  • Filter high-volume abuse
plus

Centinel adds

  • Catch stealth crawlers, not just bots
  • Read behavior across the session
  • Allow or block per crawler
