Why PerimeterX

PerimeterX Technology Platform Works With Your Existing Infrastructure

Bot Defender can be deployed anywhere with your existing infrastructure — no changes required. PerimeterX Technology Platform can be integrated into any website within minutes. Over forty pre-built PerimeterX Enforcer integrations support a wide range of content delivery networks (CDNs), load balancers, web servers and application servers. The out-of-band mode of operation is compatible with any cloud-based, appliance-based or serverless infrastructure.

Best-in-class Bot Protection for Your Web Apps, Mobile Apps and APIs

Safeguard your business with industry-leading bot detection accuracy and customizable mitigation for web and mobile applications and APIs. Bot Defender uses a combination of fingerprinting, behavior-based and predictive methods to detect bots and stop hyper-distributed attacks.

Block and Mitigate Bots with Unmatched Precision

The machine-learning-based PerimeterX Detector processes numerous data signals collected by the PerimeterX Sensor. The Detector generates behavioral fingerprints to detect anomalies and continuously updates the Sensor with new intelligence. The PerimeterX Enforcer is integrated inline with existing infrastructure to efficiently mitigate unwanted bot traffic based on the insights provided by the system and according to your business needs.

Powered by the PerimeterX Platform

Bot Defender runs on the cloud-native PerimeterX Platform which provides common services for the PerimeterX product portfolio, enabling full visibility and control of your web and mobile applications and APIs. The Platform also powers PerimeterX Code Defender and PerimeterX Page Defender which protect your website against security threats including unauthorized third-party code changes, unwanted browser extensions and ad injections.

How Bot Defender Works

  • Collect

    The Sensor collects and sends hundreds of client-side indicators to the detector for precise determination of human versus bot activity. The signals or indicators are used to create the device and browser fingerprints. The Sensor does not collect or store PII data.

  • Detect

    The machine learning (ML) based Detector continuously learns the normal range for human interactions, correlates it with customer-defined policies and updates the Sensor with new intelligence. The Detector maintains a growing repository of known attacks, anonymizes and aggregates across all customers to increase accuracy. The Detector frequently updates its training data set and augments its ML features based on internal and external data, which means best-in-class protection.

  • Enforce

    The Enforcer is the gatekeeper for threat response policies generated by the detector. It enriches and mitigates bot traffic according to business needs. The Enforcer also continuously learns and updates the Detector with relevant data. The Enforcer can be deployed inline with any existing server-side web infrastructure.

  • Report

    The cloud-based management Portal displays all activity in real time including attacks, blocked requests and rate-limited good bots. Manage all bot traffic, good and bad, with an intuitive admin interface. With the Portal, you can investigate attacks and create custom reports.
