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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The features that I have found most useful is the ability to centralize all the rules and then distribute them across various locations. However, I've encountered challenges related to tagging policies, which can be complex to devise. It's a matter that requires careful consideration and stakeholder involvement before implementing such policies."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
"The dependency map is most valuable feature."
"The solution is easy to use."
"Customer support is excellent."
"The solution helps to maintain logs and monitor activities. It also helps us with access management. The tool helps us to secure organizational data that include files."
"The Explorer allows you to know the traffic between source and destination."
"I would recommend Illumio to all sizes of companies."
"The solution is very stable and reliable."
"The initial setup is straightforward."
"The best part is the blueprint creation where I can create their things and then move on to the target environment."
"VMware NSX has the ability to create networks in software."
"The dashboard is comprehensive and easy to use."
"The initial setup is easy and takes between one and five days."
"VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided."
"The organization of it is logical, useful, and intuitive."
 

Cons

"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"Some of the features that can be improved is offer additional guidance on creating an effective and risk-free tagging policy would be highly beneficial."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades. This would be more helpful to streamline processes."
"I would like to see better data security in the product."
"The customer service is lagging a bit. It could be better."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"The price could be better. The non-enterprise version of the product should also be improved. I would like VMware to expand beyond the network and provide some VLAN technologies and more. I think we have one, but it's more on the distribution side because it's more on the upper side of the network. I'm looking forward to that."
"The initial configuration and integration within our existing environment were not easy."
"Its licensing model could be VM based."
"We would like better integration with the standards on the market. For example, with OSPF, their integration in NSX is very low. It's not a full OSPF integration. It is too thin from a protocol perspective."
"The training costs a minimum of $3,000, which is expensive and should be reduced."
"There were some issues with finance and other accounting."
"The licensing model is expensive and could be more flexible, especially after Broadcom bought VMware. It made it an expensive licensing model with no other options to take something specific from the license itself."
"The feature it can improve is essentially application-based load balancing with intelligent load distribution for applications that require redundancy and high availability."
 

Pricing and Cost Advice

"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
"The tool's pricing is reasonable."
"The licensing fees are expensive and we pay on a yearly basis."
"The price is pretty high."
"The pricing model for VMware NSX is good."
"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."
"The subscription is on a yearly basis."
"VMware has always been geared towards enterprise and their pricing options are a bit high. Their price is higher than other options in the market."
"The solution is reasonable at the local level."
