Vigilant

Vigilant — Safer Browsing, Made Simple

Vigilant is a browser extension designed to help users identify potentially deceptive, malicious, or unsafe websites before they interact with them. It works quietly in the background, analyzing website addresses and alerting you when something looks suspicious.
Deceptive websites often rely on look-alike domains, misleading language, or subtle tricks to confuse users. Vigilant helps surface these risks so you can make informed decisions while browsing.

How Vigilant Works
When you visit a website, Vigilant analyzes the domain and URL structure using multiple security checks, including:
• Domain similarity detection to identify look-alike or visually deceptive domains. This features compares the input domain against the urls in your browser history that you have previously interacted with.
• Unicode and punycode analysis to detect hidden or misleading characters
• Lexical and language analysis to flag unusual, suspicious, or misleading domain patterns
• Machine learning based classification that evaluates URL features and behavioral signals to predict phishing or malicious intent
• Threat intelligence signals, including known phishing, malware, or scam indicators (when available)
• URL comparison against live databases of reported phishing and malicious URL's

If potential risk is detected, Vigilant displays a clear warning explaining what was found and why extra caution may be needed.

Vigilant does not block websites or claim that a site is malicious. It provides risk signals and guidance, allowing you to decide how to proceed.
