Inside the Engine

URLert is an orchestrated system of specialized AI agents.

Domain Intelligence

Before scanning content, we analyze the domain. We check for Typosquatting (e.g., `paypa1.com`), domain age, and high-risk TLDs to catch attacks before they even load.

Typosquat Detection Newly Registered Domain

The Orchestrator

Our "Fail-Fast" engine. If the domain is obviously malicious, we stop there. If it's suspicious, we trigger deeper scans. It intelligently routes the URL to optimize speed and cost.

Context-Aware Smart Routing

Static & Cloaking Analysis

We simulate multiple visitors (Mobile Device, Desktop, GoogleBot) simultaneously. This forces "Cloaking" attacks to reveal their true payloads targeting mobile victims.

Anti-Cloaking User-Agent Variance

Visual & Behavioral

For high-stakes URLs, we launch a headless browser. We use Computer Vision to "see" the page like a human, detecting fake login forms and drive-by downloads that code analysis misses.

The AI SOC Analyst

Finally, our LLM Synthesizer reviews all findings. It acts as a Senior Security Analyst, ignoring noise and writing a human-readable explanation of why the site is dangerous.
