Radware Bot Manager

Difficulty 4/5

The former ShieldSquare engine. Intent-based scoring, most visible through its `validate.perfdrive.com` interstitial.

  • TLS fingerprinting
  • JS challenge required
  • Behavioural scoring
  • IP reputation weight: high

How it decides

  • Device and browser fingerprinting joined to a per-visitor intent score.

  • A redirect to `validate.perfdrive.com` for anything it wants to re-check.

  • Crowd-sourced bot intelligence shared across its customer base.

What you see when it stops you

  • A redirect to `validate.perfdrive.com`
  • `_rdblts` cookies or `x-sl-compstate` headers
  • HTTP 403 at the end of a redirect chain

What actually gets through

  • Residential exits and a real browser.

  • Follow the validation redirect properly and keep the resulting cookies — clients that drop the chain are trivially flagged.
