Why it matters

1CertiLayer utilizes a four-model AI pipeline: Rule Gates (M1), Siamese LSTM (M2), XGBoost Classifier (M3), and Contrastive AE (M4).
2The platform extracts 34 behavioral features per session, including IKI timing and mouse curvature, to generate a Human Confidence Score (HCS) in under 10 milliseconds.
3CertiLayer offers a freemium pricing model, with a Free plan providing 5,000 sessions/month and a Starter plan at $19/month for 100,000 sessions.
4API rate limits range from 60 requests/min on the Free plan to 5,000 requests/min on the Enterprise plan.

overview

What is CertiLayer?

CertiLayer is a behavioral biometrics tool developed by CertiLayer that enables security teams and product owners to differentiate real humans from automated bots through passive behavioral verification. It operates by analyzing user interactions such as typing, scrolling, and mouse movements without relying on CAPTCHAs or collecting Personally Identifiable Information (PII). The system processes 34 behavioral features per session, including IKI timing, mouse curvature, scroll entropy, touch pressure, and motion jitter, via a lightweight 5.5KB SDK. This data is then fed into a four-model AI pipeline comprising CertiLayer proprietary M1 — Rule Gates, CertiLayer proprietary M2 — Siamese LSTM, CertiLayer proprietary M3 — XGBoost Classifier, and CertiLayer proprietary M4 — Contrastive AE. The output is a Human Confidence Score (HCS) between 0.0 and 1.0, delivered within 10 milliseconds.

features

Key Features of CertiLayer

CertiLayer's core functionality revolves around its advanced behavioral biometrics and multi-model AI pipeline, designed for passive bot detection and human verification.

  • Continuous passive monitoring of 34 behavioral features (e.g., IKI timing, mouse curvature, scroll entropy, touch pressure, motion jitter).
  • Velocity curves and micro-adjustments tracking for granular behavioral analysis.
  • Behavioral signal data processing with zero Personally Identifiable Information (PII) collection.
  • Multi-model AI detection pipeline incorporating CertiLayer proprietary M1 — Rule Gates, M2 — Siamese LSTM, M3 — XGBoost Classifier, and M4 — Contrastive AE.
  • Real-time Human Confidence Scoring (HCS) with P99 latency under 10ms.
  • Lightweight 5.5KB SDK for integration across various platforms.
  • REST and GraphQL API support for flexible integration.
  • Webhook events for real-time notifications (Starter plan and above).

use cases

Who Should Use CertiLayer?

CertiLayer is primarily designed for security teams, product managers, and enterprise businesses that require robust, frictionless human verification and bot detection across their digital properties.

  • E-commerce: To protect against fraudulent purchases, account takeovers, and automated scraping activities.
  • Gaming: For preventing cheating, botting, and account abuse within online gaming environments.
  • Banking: To enhance security for online transactions, account access, and fraud prevention in financial services.
  • SaaS Authentication: Securing user logins, preventing credential stuffing, and ensuring legitimate access to SaaS platforms.
  • Marketplaces: To maintain fair interactions, prevent automated exploitation, and secure transactions on online marketplaces.

how to use

How to Use CertiLayer

CertiLayer can be integrated into web and mobile applications via its SDKs and APIs to begin passively monitoring user behavior for bot detection.

  • 1Sign up for a CertiLayer account, starting with the Free plan.
  • 2Integrate the lightweight 5.5KB SDK into your Web, Node.js, Python, or React Native application.
  • 3Configure the SDK to capture passive behavioral signals from user interactions.
  • 4Utilize the REST or GraphQL API to receive the Human Confidence Score (HCS) for each session.
  • 5Implement logic based on the HCS to differentiate between human users and bots, applying appropriate security measures.
  • 6Access API documentation at https://certilayer.net/docs/api-reference for detailed integration instructions.

Pros

  • +Completely passive bot detection, eliminating the need for CAPTCHAs and user friction.
  • +Zero collection of Personally Identifiable Information (PII), enhancing data privacy and compliance.
  • +Sophisticated four-model AI pipeline (Rule Gates, Siamese LSTM, XGBoost, Contrastive AE) for high detection accuracy.
  • +Low latency Human Confidence Score (HCS) generation, with P99 under 10ms.
  • +Lightweight 5.5KB SDK and comprehensive API support (REST, GraphQL) for flexible integration.
  • +Offers a free tier for initial evaluation and small-scale use.

Cons

  • −Specific user reviews on major software review platforms are not widely available, making independent reception assessment challenging.
  • −Reliance solely on behavioral biometrics might have limitations in scenarios where advanced bots mimic human behavior perfectly.
  • −The effectiveness of the proprietary AI models is primarily detailed in CertiLayer's own whitepaper, requiring trust in internal validation.
  • −Pricing scales with session volume, which could become costly for extremely high-traffic applications beyond the Scale plan.
