Alark Singh - PeerSpot reviewer
Visual traffic interface aids in network micro-segmentation while a streamlined update option enhances process efficiency
The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies. We can write rules that can be embedded into the IP table, making it easy to handle. Illumio enables us to see network flows, traffic sources, and destinations. The policy generation and enforcement capabilities are valuable, allowing for selective enforcement. Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.
MagdyRaafat - PeerSpot reviewer
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.
