Featured Reviews

Raja Xabi - PeerSpot reviewer
Technical Manager at APRAL
Improved bandwidth management and network visibility have resulted in financial benefits and streamlined operations
There is always room for improvement in SolarWinds NetFlow Traffic Analyzer, such as implementing instant reporting based on business intelligence reports and more granular filters in their dashboard to improve the GUI view and reporting. The licensing model of SolarWinds NetFlow Traffic Analyzer is always an issue for users because competitors offer unlimited and perpetual licenses, and SolarWinds NetFlow Traffic Analyzer's model is quite costly compared to other brands. If users are comfortable with SolarWinds NetFlow Traffic Analyzer, they have to make the hard decision to invest, and it's suggested from a user's perspective that SolarWinds should improve their financial model and licensing to become competitive, especially for small to medium businesses.
TAIYAB HASAN - PeerSpot reviewer
Windows Redhat Linux Vmware & Azure & Cloud & Nutanix Ahv-Vmware & Backup Senior System Administrator at AlDawaa Medical Services
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.
