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.

Enhanced security and streamlined management drive efficient connectivity
Open source is a standard solution where you take a gray box or white box and put the software from your end. You can do programming with Ansible and make the network work in the software-defined mode, providing automation and management capabilities. I am currently working with VMware. It integrates easily with everything and can work with any system. When discussing micro-segmentation, it enhances security, providing more secure data in your data center while allowing for extra layers of security outside your data center. If you have an ACI, there is communication between locations, keeping your data secure in your data center and throughout the path it takes, such as to SD-WAN or the cloud. I work with cloud solutions including AWS, Azure, GCP, and private cloud. My overall rating for VMware NSX is 8.5 out of 10.
