LightDec Guard by Falcons.ai

Blocks fake and spoofed sign-in pages before you enter your password. All checks run on your device; no browsing data leaves it.

LightDec Guard by Falcons.ai stops fake sign-in pages before you type your password. It checks every page that asks for credentials, and it runs entirely on your device: • Lookalike addresses: punycode homographs (pаypal.com with a Cyrillic "а"), typosquats, combosquats and brand names hidden in subdomains. • Brand impersonation: a page that presents itself as Microsoft, PayPal, Google and others but isn't on that brand's official domain. • Credential exfiltration: forms that post your password to messaging bots and drop endpoints such as Telegram APIs. • Hidden prompt-injection text and image-only login pages built to fool automated checks. What happens: • Block: a full-page warning. Password fields are locked and submissions are cancelled. You can still continue for that session after an explicit acknowledgement. • Warn: a banner, plus a "Send your password to this site?" confirmation before anything is sent. • Allow: no friction on legitimate sites. Click the toolbar icon to see exactly why a page was blocked or allowed. Privacy: page analysis never leaves your browser. There is no telemetry and no account. An optional "remote second opinion" is off by default and only uses an endpoint you configure yourself. On-device AI: LightDec Guard ships Falcons.ai's Athr_Agent_Sec model and runs it in your browser with ONNX Runtime (about 5 ms per page). On every sign-in page it checks the hidden text for instructions aimed at AI scanners. When it confirms what the rules found, a warning becomes a block. It never blocks or allows a page on its own.
