Complete AI security suite — threat detection, website reputation, phishing protection, breach monitoring, download safety 🛡️ CyberShield — AI Browser Security Suite CyberShield is a comprehensive, privacy-first security extension that protects you from modern browser threats in real time — phishing attacks, credential theft, GenAI data leakage, malicious downloads, scams, and more. Every scan runs 100% on-device. No data leaves your browser. 🤖 AI-Powered Prompt Protection for GenAI Chat Services Before your prompt is sent to any AI chat service, CyberShield scans it silently on-device: Automatically detects secrets and API keys — including cloud provider keys, code hosting tokens, payment processor keys, private keys, and bearer tokens — and blocks them from being sent Detects personal and financial data such as national identity numbers, payment card numbers, bank account details, passport numbers, email addresses, phone numbers, and dates of birth, then shows a confirmation overlay before sending Redact & Send — one click auto-replaces sensitive values with typed placeholders like ‹EMAIL_REDACTED› so your prompt stays useful while your data stays private Detects prompt injection attacks, jailbreak attempts, role manipulation, and system-override patterns using an on-device ML model 🔍 Advanced Phishing & Threat Detection Research-backed phishing engine drawing on 10+ academic detection models Detects spear phishing, credential-harvesting forms, typosquatting, and brand impersonation Real-time URL risk scoring — free hosting abuse, suspicious domain patterns, URL shorteners, and brand-in-path attacks OAuth consent phishing detection — warns when apps request overly broad account access or redirect to suspicious hosts Floating page trust indicator shown on every site you visit 📁 File Upload DLP (Data Loss Prevention) Scans documents, spreadsheets, source code, configuration files, and images before they are uploaded to any AI chat service OCR scanning of screenshots and image files to catch sensitive data in visual content Instant per-finding alert if PII or secrets are detected inside a file 💬 WhatsApp & Gmail Scam Protection Real-time scan of incoming messages for payment scams, OTP-extraction attempts, impersonation, and financial lures QR code scanning inside chat images — decodes and inspects payment links, crypto addresses, and app deep-links for threats Detects malicious file attachments such as executables, macro-enabled documents, and disguised scripts Inline warning pills with expandable details shown directly inside the chat window 🌐 Search Result Safety Annotations Adds safety badges to search results across major search engines, flagging malicious, low-reputation, and phishing domains before you click. 📥 Download Protection Blocks dangerous executable and script file types automatically Flags downloads with suspicious filenames associated with malware distribution Desktop notification with allow/block action before the file is saved 🔓 Data Breach Monitoring Check if your email has appeared in known data breaches using privacy-preserving k-anonymity — your email is never sent in full Password breach check using hash-prefix lookup — your password never leaves your device Optional periodic background monitoring with breach alerts 🧩 Extension Security Auditor Scans all your installed browser extensions for risky permissions, broad site access, and non-store install methods Scores each extension and flags high-risk or sideloaded ones with a plain-language reason list Runs automatically on install and periodically in the background 🤖 Shadow AI & SaaS Discovery Detects when you visit unsanctioned AI tools or risky file-sharing and paste services Builds a local usage inventory so you stay aware of what services you are using No data sent anywhere — the inventory is stored only in your browser 🔐 OAuth Consent Guard Intercepts authorization screens from major identity providers and highlights over-broad scope requests in red Warns when redirect destinations point to IP addresses, temporary hosting services, or look-alike domains — a common consent phishing technique ⭐ Website Reputation & Trust Scoring On-demand reputation check for any domain, with per-site configurable link risk badges and misleading-content warnings. Privacy-first by design: ✅ All scanning runs 100% on-device — no prompts, URLs, or personal data reach any external server ✅ Chrome Web Store compliant — raw source, zero obfuscation ✅ Works fully offline for all core protections
