Janus Cybersecurity Case Study|Seamless and High-ROI Protection for EOS Systems
Safeguarding Legacy Systems and Unpatchable Infrastructure with Janus

事例概要
This client is a well-established Asian system integrator with over 20 years of experience supporting government, finance, and enterprise clients. To maintain long-term service stability, some servers still operate on unsupported OS like Windows Server 2003, making updates and conventional cybersecurity solutions impossible.
Cybersecurity Risks & Challenges:
- Blocked multiple unauthorized access attempts and scans targeting legacy assets
- Shifted from "open exposure" to "minimum necessary communication" model
- Prevented potential outages and reputational loss
- Reduced 80%+ of manual maintenance and analysis workload
結果として
Janus netKeeper is not a conventional security device, but a smart embedded solution designed for EOS systems. It is deployable without disrupting operations.
📌 What Makes Janus Different?
- Uses patented AI to learn communication patterns and generate dynamic, auto-adjusting whitelists.
- Converts complex risks into quantifiable scores, instantly isolates abnormal behavior.
- Implements zero-trust principles through granular, communication-based microsegmentation.
📌 Results & Benefits
- Blocked multiple unauthorized access attempts and scans targeting legacy assets
- Shifted from "open exposure" to "minimum necessary communication" model
- Prevented potential outages and reputational loss
- Reduced 80%+ of manual maintenance and analysis workload
📌 Quantified ROI Impact
Assumptions (based on 10 EOS systems)
- Annual manual operations cost exceeds hundreds of thousands of NTD
- Each breach may cause losses up to a million NTD
- External audit and remediation cost significant additional budget
📌 ROI Summary
- Over 80% reduction in manual labor, cutting personnel costs
- Over 90% reduction in exposure risk and improved threat blocking
- Annual savings exceed 50% of total pre-deployment security spending
- Average ROI surpasses 250% in 3 years, with payback in under 2 years
"We couldn't replace these legacy systems, but Janus gave us a way to protect them without disruption. It took a huge weight off our security operations."
