Browser Extension Phishing Protection
A lightweight browser add-on that analyzes URLs and page content in real time to block phishing attacks at the point of interaction.
Overview
Browser extension phishing protection operates at the universal enforcement point: the moment a user clicks any link, regardless of the delivery channel. Unlike email gateways that only inspect messages at ingress, a browser extension evaluates every URL as it loads - checking for brand impersonation, credential harvesting forms, suspicious redirects, and domain anomalies. This makes it the only phishing defense layer that covers email, chat, SMS, social media, QR codes, and shared documents simultaneously. PhiShark's browser extension connects to the AIPA analysis engine for deep, agentic investigation of every suspicious page, delivering verdicts in milliseconds without slowing down the user's browsing experience.
