Care0 serves 2.4 million members with Auth0-powered identity infrastructure. Credential stuffing, account takeover, and bot attacks are stopped automatically — with zero disruption to the care experience.
Security Architecture
Auth0's layered defenses work together — JA4 signals stop sophisticated bots that traditional detection misses, and Credential Guard catches breached phone credentials that password databases don't cover.
JA4 fingerprinting analyzes TLS client hello signatures. Automated tooling produces fingerprints fundamentally different from real browsers — catching residential proxy attacks that IP reputation misses.
Detects breached phone credentials from SIM swap attacks and telecom breaches. For healthcare portals where phone-based MFA is standard, this closes a critical gap beyond traditional password databases.
Incident Response
A coordinated credential stuffing campaign targeted Care0 with 50,000 login attempts in under an hour. Here's what our members experienced: nothing.
Distributed botnet initiates credential stuffing across 1,200+ IPs using residential proxies and rotating phone numbers
TLS fingerprinting identifies automated tooling — residential proxy traffic with clean IPs flagged by JA4 hash mismatch. 94% of traffic blocked.
Credential Guard detects breached phone numbers from SIM swap and telecom breach databases. Members re-routed to secure verification.
49,700 of 50,000 attempts blocked. Zero account compromises. Zero engineers paged. Members unaffected.
