This case involves one of Taiwan’s top five EV charging network operators, with over 1,000 stations across highways, offices, malls, and residential areas. As the business scaled, cybersecurity became essential for operational continuity and brand trust.

Before Janus, key security challenges included:
- Diverse device types at sites made unified inventory difficult
- Devices connected to public networks were exposed to attacks
- No identity verification mechanism for connected devices
- Incidents were often discovered only after user complaints

With Janus deployed, without any infrastructure redesign, the operator could:
- Automatically generate whitelists and block abnormal traffic
- Instantly block unauthorized devices
- Proactively detect anomalies and alert ops teams for fast response

⚠️ At one station, a power outage caused device disconnection. Janus detected and alerted the issue first. The ops team resolved it within 40 minutes—no complaints or data loss.
