The shield that keeps your private number, private

Kerno acts as an intelligent firewall for your phone. Decide who can reach you, block unknown calls, and protect your number from spam, fraud, and impersonation.

Protected

Why are we still using an insecure system?

Your phone number is exposed by default. Anyone, even malicious actors, can call you, impersonate you, or scam you. Every day, millions fall victim to phishing, vishing, and SIM-swapping attacks.

Kerno protects your line like a firewall protects your network

All calls and messages are routed through encrypted, one-to-one aliases. If a caller isn't verified or approved, the connection simply doesn't go through. Each attempt is logged, so you know exactly who tried to reach you.
