How PhishGuard Works
A transparent, multi-layer analysis pipeline — not a black box.
Submit
Paste a URL, upload a QR image, or paste email content.
Extract
Features are extracted — domain structure, entropy, QR payload, email headers.
Analyze
Our trained ML model and independent heuristic engine both score the input.
Report
A combined risk score, confidence level, and clear indicators are shown.
Three Ways We Protect You
Every input goes through the same rigorous risk engine.
URL Analysis
30+ engineered features — domain structure, entropy, suspicious keywords, TLD reputation and more — combined with independent heuristic rules.
QR Code Analysis
Decodes URL, text, Wi-Fi, and payment QR codes — including EMV/MMQR-style payment payloads — without guessing providers it can't confirm.
Email Analysis
Detects urgency language, credential requests, sender/display-name mismatches, and extracts every embedded URL for full analysis.
A Model Trained on Real Data — Not a Wrapper
Our detection engine is trained locally using scikit-learn, with domain-aware evaluation to prevent data leakage. We report real precision, recall and generalization — not inflated accuracy numbers.
- Domain-grouped train/test splitting to avoid leakage
- Calibrated probabilities, not raw model scores
- Independent heuristic engine as a second opinion

- RandomForestClassifier

Full metrics published in the admin dashboard after training (Phase 12–13).
Built With Security First
No SSRF exposure
Server never blindly fetches user-submitted URLs against internal networks.
Privacy by design
Email bodies are hashed, not stored — only indicators are retained.
Role-based access
Every admin action is server-side authorized, not just UI-hidden.
Full audit trail
Logins, scans, and admin changes are logged for accountability.
