What It Does

Features

🧬

Behavioral AI Analysis

Analyzes how page scripts behave — not just what they contain. Detects obfuscated malware, fingerprinting attempts, and novel phishing flows by their behavioral signatures.

🌐

Global Threat Intelligence

Aggregates real-time threat feeds from multiple security vendors, government CERTs, and community sources into a unified intelligence layer.

📝

AI-Powered Explanations

When SentinelX flags a threat, it provides a plain-English explanation of exactly what it found, why it's dangerous, and what to do. No jargon.

⚙️

Custom Rule Engine

Define your own detection rules in a simple YAML-based format. Share rules with the community or keep them private for enterprise use.

🔗

ZeroTrust Integration

Designed to complement ZeroTrust — install both for layered defense. SentinelX handles behavioral AI, ZeroTrust handles signature matching.

📈

Weekly Threat Reports

Receive weekly digest reports summarizing the threats encountered in your browsing, trends in the threat landscape, and risk score trends.

🧪

Sandbox Analysis

Suspicious scripts are executed in an isolated sandbox to observe behavior before they run in the live page context.

🔮

Predictive Blocking

ML models trained on attack patterns block likely-malicious domains before they execute any code, based on registration patterns and behavioral history.

The Process

How It Works

Observe

SentinelX instruments the browser's JavaScript engine to observe script behavior — API calls, DOM access patterns, network activity — in real time.

Analyze

Behavioral signatures are matched against an on-device ML model. Anomalous patterns trigger deeper analysis via optional AI reasoning through your API key.

Protect

Threats are blocked before they execute. You receive a plain-English explanation of what was found and why. Every decision is logged for review.

Transparency

Permissions Explained

Every permission is documented here with the exact reason it's needed. Nothing is requested unnecessarily.

🌐

webRequest

To analyze network requests for behavioral anomalies and suspicious communication patterns.

📑

activeTab

To perform deep behavioral analysis of page content and scripts.

💾

storage

To store local ML model weights and behavioral baselines.

Frequently Asked Questions

We're targeting Q3 2025 for the public beta. Sign up for early access at support@alphabytecore.com with the subject 'SentinelX Early Access'.

ZeroTrust uses a threat signature database — it's excellent for known threats. SentinelX uses behavioral AI to catch unknown, novel threats. Together they provide comprehensive coverage.

Basic behavioral analysis runs entirely on-device using a local ML model. The AI explanation feature optionally uses your Anthropic API key for richer analysis.

Yes. Enterprise features including custom rule distribution, team dashboards, and SIEM integration are planned. Contact us for early enterprise access.
