Results
- 90Gbps throughput
- 75% reduction in power consumption
- Minimal packet loss and improved latency
- Just two clicks to configure and deploy
This was a full proof of concept in a real-world environment. The trial proved that our SAFE Series hardware can run high-speed encryption with near-zero impact on performance, even in demanding telecom conditions.
