Invisible Challenges

How PerimeterX detects and blocks bots and attackers without the end user seeing the challenge

As an integral part of Bot-Defender, PerimeterX operates invisible challenges allowing us to detect and block attackers with little impact on actual users.

These challenges usually contain the following characteristics:

  • Harder to be reverse engineered
  • Detecting advanced attacks
  • Detecting spoofing (e.g. gen3 bots, trying to mask themselves as primitive bots)
  • Forcing attackers to expend more CPU time thereby negatively impacting the ROI of the attack and deterring it. Read more about Proof of Work
