About this extension
VigilSpan protects company browsers from the attacks that get past email filters and antivirus: they live in a browser tab, on a fresh domain, for a few hours.
• Phishing and reverse-proxy (AiTM) login kits, look-alike domains and fake login windows
• ClickFix and fake CAPTCHAs: malicious commands are replaced before they reach the clipboard
• Remote-access scams: ScreenConnect "guest" invites and AnyDesk/TeamViewer installers from anywhere but the vendor
• Fake browser updates, smuggled downloads, tech-support scams and pop-up floods
• Card skimmers and form grabbers, consent and device-code phishing, risky extensions
Detection runs on the device. Alerts are end-to-end encrypted to your organisation's key: only your security team can read them, not even VigilSpan.
Requires a VigilSpan organisation. Request access at https://vigilspan.com
