Frequently Asked Questions

Everything you need to know about PhishGuard's machine learning model, Gemini integration, and privacy guarantees.

Scikit-Learn executes deterministic, sub-15ms statistical feature classification to generate a numeric risk probability score. Gemini 2.5 Flash then analyzes the full text semantics to generate plain-English threat breakdowns and actionable remediation steps.
PhishGuard includes built-in offline fallback logic. If the Gemini API call times out or encounters quota limits, the local Scikit-Learn risk score and static defensive guidelines are returned instantly without breaking the application UI.
No. All email payload inspections are processed dynamically in-memory and discarded immediately after returning the classification result. No logs or records of email text are stored on any database or third-party storage.
PhishGuard utilizes a supervised Logistic Regression model trained on high-dimensional TF-IDF unigram and bigram matrices extracted from 100,000+ benchmarked email samples, achieving a 97.3% validation accuracy.
Instead of relying purely on static domain blocklists, PhishGuard inspects linguistic patterns (such as artificial urgency, impersonation markers, and credential harvest phrasing), enabling it to flag brand-new zero-day attack vectors instantly.
Yes. The backend exposes a RESTful JSON endpoint (`POST /predict`) designed to receive raw text strings and output standardized risk probabilities along with AI threat analysis payloads.
