SYBA Shield is the cyber-concierge that lives in your browser toolbar. Toggle it on with one click and every page you visit gets a security check.
Three layers of defense, all on by default:
1. URL heuristics — instantly catches lookalike domains (paypal-secure-login.com), IDN homograph attacks (apple.com written with Cyrillic letters), suspicious TLDs, IP-literal hosts, embedded credentials. Offline, private, sub-millisecond.
2. DOM signals — flags password fields on plain HTTP, login forms posting to a different domain, login pages themed for one brand but hosted on another, hidden iframes sized for clickjacking, urgency language pressuring you to act fast.
3. Vision AI scan — when you click Scan now, SYBA Shield captures the visible tab and asks a multimodal AI to look at the page like a human would. It catches fake browser warnings, fake MFA prompts, lookalike logos, and "your account is locked" pressure tactics that pure URL checks would miss.
Plus the v0.2 features:
