What people are saying

First Cagayan Converge Data Center “Fair usage was the biggest requirement for us, but FlowCommand has provided a number of other great benefits in terms of much more advanced and instantaneous visibility, analytics and control. The control of our bandwidth is markedly better across the board. We’ve improved bandwidth utilization by more than 30%, which has translated into a more than $80,000 bandwidth cost savings and delayed capex on upgrades for more than 6 months”

Edgardo Lopez, First Cagayan Converge Data Center, Inc. Chief Technology Officer

Sunway Information Technology “Saisei’s software has paid off in a number of ways. The two gaming operators who threatened to take their business elsewhere have decided to remain our customers. And we’ve been able to eliminate the 5-millisecond latency that can terminate a gaming session and its associated revenue.”

Daniel Soh, Assistant General Manager, Sunway Digital Wave

NHN Entertainment “Saisei’s software is critical for us. It’s helping us provide a high-quality gaming experience to our end users around the globe which is important to increasing customer loyalty and expanding our business. Saisei’s software is unique in its ability to do micro-flow level monitoring without packet capturing. It’s extremely easy to use. We looked at many of the top networking products but they were very costly and complex, and most were hardware based so we couldn’t utilize our unused servers in our data centers.”

Joohwan Kim, NHN Entertainment Infra Operation Team Leader

Fort Bend County Libraries “FlowCommand gives us great visibility and control, and also does an excellent job of augmenting the security on our network because we can see so much more. From the dashboard, we can now immediately see where traffic is coming from – and can really hone in on, for example, the top 25 applications being used and by which users, devices and locations – on a second-by-second basis. We’ve also gained a lot more control by using the software’s host equalization capability, which ensures every user has equal access to our local Wi-Fi networks and gets great applications performance, regardless of how many users are on the network or what applications they are running.”

Raymond Miranda, Network Specialist at Fort Bend County Libraries
