How it works
From open to verdict
in four steps.
01
You open an email
The moment Gmail loads an email, PhishNet silently activates in the side panel.
02
AI analyzes threats
Headers, sender reputation, link safety, content patterns, and attachment hashes — all checked in parallel.
03
Verdict delivered
A confidence score, risk level, and plain-English explanation appear instantly — safe, suspicious, or phishing.
04
You take action
Quarantine, report, or reply with one click. High-risk emails can be auto-quarantined before you even see them.
Real-time analysis

A threat score in under 80 milliseconds.

Six threat models run in parallel the moment you open an email — before you can click a bad link, before you can forward it. All scoring happens server-side with no latency impact on Gmail.

Hi, just checking in on the Q4 timeline — can you confirm sign-off by EOD today? We need to lock the schedule for the stakeholder review.
