We see a world where opening or sharing a link is always safe. MetaCert was founded on a simple belief: online trust shouldn’t be a gamble. People are told to “stay vigilant” and “check suspicious links,” putting all the burden on them. But phishing links are designed to look real, and even experts get fooled. Phishing remains the single entry point for most online attacks, from fraud and identity theft to ransomware and account takeovers. It keeps growing because the security industry still assumes new phishing links are safe until proven dangerous. We changed that. MetaCert invented Zero Trust URL Authentication, a new model that treats every link as untrusted until verified as legitimate. Like checking a person’s ID before entering an office building, every link should be verified as legitimate before being trusted. Our Link Verifier app is the first of its kind. Once installed, it works directly from your iPhone’s share menu across almost every app — Messages, Mail, WhatsApp, Gmail, browsers, QR scanners, and more. No setup, no switching apps. Just two taps to see if a link is verified, unverified, or dangerous. 🟢 Green means verified ⚪️ Grey means unverified 🔴 Red means dangerous This simple signal system has already proven itself. Our browser extension using the same technology protected hundreds of thousands of crypto traders without a single reported scam. MetaCert isn’t just an app. It’s a platform. Our Zero Trust Verification Service is now opening to banks, telecoms, eSIM providers, crypto companies, and security vendors. They can embed our real-time link authentication into their own products to protect customers in every app that exposes them to online impersonation. And for mobile operators, we offer Zero Trust SMS, a network-level solution that verifies every link in text messages and rewrites unverified ones before delivery. No apps. No user setup. Once enabled by a carrier, everyone on the network is protected.
