AI PhishNet

AI PhishNet is a Chrome extension developed by PROSFINITY LIMITED that aims to protect individuals and organisations from phishing attacks. Its signature approach is to run two AI models over each URL: PhishNet AI One concentrates on the domain name, while PhishNet AI Two inspects the pattern and signature of the link. Analysing a URL from two angles is designed to catch zero-day phishing sites that simple blacklists would miss.

Once installed, the extension warns you before you land on a suspected phishing page. Its alert page explains what type of attack the site is attempting and the potential consequences of falling for it, while a neutral page is shown when the link matches one of the models so you can decide for yourself. You can whitelist trusted domains so they are never flagged. Two operating modes tune the sensitivity: Intensive Mode examines the whole URL including the path and query string for stronger security but more false positives, while Alert Mode warns on any suspicious site, being the most cautious but also the noisiest.

The extension goes beyond blocking by embedding Phishing User Awareness Training directly into the alert page, so users learn how to recognise attacks over time. Businesses can log in with a Company ID for organisation-level features such as shared whitelists, alert settings and phishing activity reports. The extension is early-stage — version 1.0.0, updated in late October 2025, with a small but positive rating base — and offers in-app purchases, so some capabilities likely sit behind payment.
