Featured Reviews

SupravatMaji - PeerSpot reviewer
Beneficial single unified dashboard, good native application integration, and high availability
My advice to those wanting to implement RSA NetWitness Network is they have to first do a little due diligence, such as the exact requirement based on their needs. That will give them a direction for their investment because otherwise, the bill of material or bill of quantity (BOQ) may be higher side. It is important to do good due intelligence on the environment, see the exact requirement, and then go ahead with the solution. The solution is perfectly stable. I rate RSA NetWitness Network a nine out of ten.
TAIYAB HASAN - PeerSpot reviewer
Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.
