About this app

Every day, millions of dangerous links are sent through WhatsApp, messaging apps, email, and QR codes — designed to steal your personal data, empty your bank account, or infect your device. Vigil stands between you and those threats.

Vigil is an AI-powered mobile security app that scans URLs and QR codes in real time, analyzing them across multiple threat intelligence layers to tell you exactly what a link does before you click it.

HOW IT WORKS

Paste a suspicious link, share it to Vigil from any app, or scan a QR code. Within seconds, our AI engine analyzes the URL across dozens of security signals — domain reputation, SSL certificates, redirect chains, infrastructure patterns, content analysis, and known threat databases — then delivers a clear verdict: Safe, Suspicious, or Dangerous, with a detailed risk score and plain-language explanation of exactly why.

KEY FEATURES

Clipboard Protection
Enable optional clipboard monitoring and Vigil checks links you copy, alerting you before you tap anything dangerous. Everything except the URL is discarded immediately.

QR Code Scanner
Scan QR codes to detect UPI payment scams and fake websites before you pay or log in. Camera frames are processed entirely on your device.

AI-Powered Deep Analysis
Not just a blocklist lookup. Vigil analyzes URL structure, page content, server infrastructure, SSL certificates, redirect chains, and behavioral patterns. It catches zero-day phishing sites that traditional scanners miss.

Clear Risk Scores
Every scan produces a 0-100 risk score with a human-readable verdict. Vigil tells you in plain language why a link is dangerous and what red flags were found.

Scan History & Filtering
Review your complete scan history with smart filters. All scan data is stored locally on your device and automatically purged after 30 days.

Report to Authorities
Found a scam? Report malicious URLs directly to Sanchar Saathi (DoT India) with one tap. Vigil auto-fills the complaint form so you only verify and submit.

Secure Browser
When you do need to visit a link, use Vigil's built-in secure browser with enhanced privacy controls, cookie management, and JavaScript protection.

Privacy First
Vigil respects your privacy. Scan history is stored locally on your device. No ads. No tracking. No data selling. Your security data stays yours.
