Featured Reviews

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.
DanielBass - PeerSpot reviewer
Improves network security with micro-segmentation but setup is complex
I value the ability to dynamically configure our network on the fly using VMware NSX. This flexibility is a huge advantage because it allows us to avoid static configurations that come with traditional hardware setups. Additionally, the micro-segmentation feature is beneficial for adhering to strict security regulations from our security department.

Pros

"I would recommend Illumio to all sizes of companies."
"Customer support is excellent."
"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 tool helps with my company's security posture."
"The solution is easy to use."
"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 Explorer allows you to know the traffic between source and destination."
"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."
"We are happy with the scalability."
"The most valuable features of VMware NSX are the tight integration with the VMware Hypervisor natively and the management console. We have a lot of other integrations where you are able to see the virtual machine's end-to-end visibility."
"We like that everything is integrated."
"I have found VMware NSX to be easy to use."
"They have a lot of support and specialists who can meet with the customer."
"Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack."
"VMware NSX is a very good solution. It's also a scalable solution."
"It's a beneficial tool."
 

Cons

"We need more details on areas where there is an error or a traffic blockage. I would like the tool to offer a more detailed view."
"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."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"I would like to see better data security in the product."
"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."
"I have not had the chance to experiment deeply with it."
"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."
"It's a good product, but the way that it has got so many multiple levels that need to be purchased makes it expensive and cumbersome."
"In the next release, they should enhance the visual interface. With NSX-T, it's difficult to communicate between the public cloud and the container."
"Their licensing model should make it easier to purchase licenses."
"The price is rather high."
"The support needs improvement."
"It isn't easy to deploy."
"I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies."
"One aspect that needs improvement is the need for further automation."
 

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."
"The subscription is on a yearly basis."
"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 of VMware NSX is very good compared to other solutions."
"VMware NSX isn't cheap."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
