Overview

Heuristic Phishing Detection is a security-focused API that analyzes suspicious URLs to identify phishing attacks and malicious links. Using advanced heuristic algorithms, the tool examines URL structure, domain characteristics, and behavioral patterns to determine threat likelihood without relying solely on blocklists.

This API is ideal for security teams, email filtering systems, browser extensions, and web applications that need to protect users from phishing campaigns. It provides fast, accurate risk assessment for URLs encountered in emails, messages, search results, and web content, enabling proactive threat prevention before users interact with malicious sites.

Key capabilities include real-time URL analysis, heuristic-based threat detection, and detailed risk scoring. The tool integrates seamlessly into security workflows, SIEM platforms, and automated incident response systems.
