Phishing Alert Guardian

A browser extension and email plugin that flags suspicious phishing attempts in real-time by analyzing email headers, sender patterns, and link authenticity. Users get instant warnings before entering credentials or clicking malicious links. Target: everyday internet users and small businesses tired of falling for scams.

Phishing attacks hit record volumes in 2024, and small businesses remain disproportionately targeted because they lack enterprise security tooling — that's a real, documented gap. Google Safe Browsing and Microsoft Defender SmartScreen already do a version of this natively inside Chrome and Edge, which is the uncomfortable competitive reality; any new entrant needs a meaningfully better detection rate or UX to justify installation. The $2k–$10k/mo revenue band is plausible only on a freemium-to-paid conversion model with aggressive small-business outreach, since consumer willingness to pay for browser security extensions is historically low. The biggest risk is that the built-in browser and OS-level protections are "good enough" for most users, making the activation and retention problem severe regardless of how accurate the detection actually is.
