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 most valuable feature of Illumio Adaptive Security Platform is monitoring. When I have no requirement from the other application, I can use the web block traffic to build."
"The flexibility of the solution is its most valuable feature."
"It has helped us to understand internal network visibility and firewall policy implementation. We use the product to simplify firewall policy implementation."
"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 dependency map is most valuable feature."
"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."
"The Explorer allows you to know the traffic between source and destination."
"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."
"I have found the system to be very intuitive, functional, and they have great technology."
"Provides protection for virtual machines."
"This is a good firewall and overall it is rich in features."
"The most valuable features are stability and low cost."
"They have a lot of support and specialists who can meet with the customer."
"NSX has excellent security features like virtual firewalls. I also like the micro-segmentation features, which are useful for the virtual machines inside the servers."
"The most valuable feature of VMware NSX is the load balancing and routing of firewall rules. Many of the features are beneficial."
"Provides flexibility to deploy and have network virtualization on different types of firewalls."
 

Cons

"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."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"The product’s agents don't work very well in OT environments."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"I would like to see better data security in the product."
"The customer service is lagging a bit. It could be better."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"It requires a low-level re-architecting of the product."
"We had some complexities implementing into the other parts of a network."
"It isn't easy to deploy."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"VMware NSX could improve by having more compatibility with other none Window-based operating systems."
"It lacks full knowledge of physical side of the network topology."
"The engineering team has room for improvement. They should have have more of a Knowledge Base about different case studies and should develop more advanced features. These kinds of improvements will change the way things get done."
"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."
"It takes time to do the initial setup. It is a bit slow, which is surprising."
 

Pricing and Cost Advice

"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"It is an expensive product, but cheaper than some competing solutions."
"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 implementation of VMware NSX can be cost-intensive, especially if an organization is looking for a comprehensive solution. The costs can vary based on factors like the level of conversation and discounts obtained during negotiations. Some government organizations, for instance, may find the prices relatively high, leading to concerns about budget hikes, especially when deploying the solution across the entire organization. Regarding maintenance and support, they are typically included in the standard licensing costs for enterprise-level businesses. While these costs can be significant, many companies opt for standard licensing to ensure they have access to necessary support and maintenance services."
"The price is significantly high and it can be a hurdle for many potential users."
"The pricing model for VMware NSX is good."
"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."
"There is a license required for this solution, we pay annually."
"The tool's pricing is reasonable."
