Transforming IoT Security Standards.
CASE STUDY
Legacy ≠ Liability. Janus Delivers Practical, Zero-Disruption Security for Unpatchable OT Assets.
With no need for downtime or endpoint changes, Janus uses behavioral modeling and hardware-level micro-segmentation to protect legacy and EOS devices in active production.
Case Overview
In operational environments, legacy and end-of-support (EOS) devices remain essential to production — but they often fall outside traditional IT security controls. They can't be patched, upgraded, or protected by endpoint tools, leaving security teams blind to major risk.
This case involves a Taiwanese manufacturer whose OT environment was hit by ransomware in 2024. Attackers used a third-party account to breach the main system and rapidly spread across over 40 unprotected legacy devices, halting production for three days and causing over NT$10 million in losses.
After the incident, Janus was deployed with no disruption to the factory floor:
- Full network traffic visibility and AI-powered behavior profiling
- Auto-generated micro-segmentation rules to isolate device groups
- Continuous daily policy updates to reduce manual security workload
Key Results
- Device communication reduced from 78% to under 10%, shrinking attack surface
- High-risk EOS assets were identified and isolated
- Gained visibility and control over devices previously unmanaged by IT
