LR GuardBot Detection

Cut bot-driven loss without punishing real customers.

Get a continuous bot risk score from mouse, keyboard, scroll, and browser-integrity signals—so you block credential stuffing and scrapers while keeping checkout and signup flows smooth for humans. Sub-50ms scoring fits inline with your existing allow or challenge rules.

Capabilities

Everything you need

ML Behavioral Analysis

Deep learning models analyze mouse movements, scroll patterns, keystroke dynamics, and interaction timing to build a behavioral profile.

Headless Browser Detection

Detect Puppeteer, Playwright, Selenium, and other automation frameworks through browser API inconsistencies and JavaScript environment analysis.

Interaction Biometrics

Track mouse velocity, acceleration, jitter, and click patterns. Bots produce statistically distinguishable interaction signatures.

Browser Integrity Checks

Verify that navigator properties, WebGL capabilities, and JavaScript APIs are internally consistent and match the claimed browser.

Real-Time Scoring

Every request receives a bot score from 0.0 (definitely human) to 1.0 (definitely bot) with sub-50ms processing time.

Challenge System

Configurable invisible challenges for edge cases. CAPTCHA-free verification that doesn't interrupt the user experience.

Session Tracking

Monitor behavior across the entire session, not just a single request. Detect bots that mimic human behavior initially but diverge over time.

Framework Detection

Identify specific automation tools — Puppeteer, Playwright, Selenium, PhantomJS, and 20+ others — with tool-specific signatures.

Adaptive Thresholds

ML models continuously retrain on new bot patterns. Zero-day bot frameworks are detected through anomaly detection without manual rules.

How It Works

Three steps to get started

01

Add the SDK

One client bundle starts passive collection on pages you protect—no extra UI until you choose to challenge.

02

Observe real behavior

Guard scores pointer dynamics, scroll rhythm, keystroke timing, and environment consistency across the session, not just the first request.

03

Enforce your policy

Use bot score and labels in your WAF, app logic, or queue—allow, rate-limit, CAPTCHA, or hard-block based on thresholds you own.

Use Cases

Built for real-world security

Credential stuffing at scale

Throttle or block login floods that use valid passwords from breaches—score spikes before your IAM lockouts frustrate real users.

Inventory & checkout bots

Protect sneaker drops, event tickets, and limited SKUs by denying high-confidence automation while preserving throughput for humans in line.

Scraping & price intelligence

Raise cost for headless harvesters that hammer catalog and pricing APIs so competitors and aggregators stop treating your site as a free feed.

Lead & signup spam

Keep fake accounts and SEO spam out of trials and contact forms—often without showing a CAPTCHA to trusted traffic.

API & partner endpoints

Layer Guard in front of public or partner APIs where tokens leak: score the client behavior, not just the key.
