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.
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.

Pros

"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 solution is easy to use."
"The tool helps with my company's security posture."
"I would recommend Illumio to all sizes of companies."
"The Explorer allows you to know the traffic between source and destination."
"The flexibility of the solution is its most valuable feature."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
"The dependency map is most valuable feature."
"I really like the management dashboard, the tailor-made assurance, the telemetry, and the ease of integration with all other solutions of VMware, such as vSphere."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"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."
"When you have a solid secure solution between your on-prem and cloud solution, then you're in a safe place."
"We secured our organisation with Micro-segmentation."
"I have found VMware NSX to be easy to use."
"You can easily integrate this with other VMware products. It is a robust solution."
"NSX gives us the ability to put our network, NSX, onto any network there is, which allows us not to have to go to the network team to create networks our VLANs for networks."
 

Cons

"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."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"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 customer service is lagging a bit. It could be better."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"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."
"I have not had the chance to experiment deeply with it."
"The price is rather high."
"In the future, the solution should be compliant with internet NIC."
"A faster resolution time would be beneficial."
"VMware NSX should be able to scale for different customers, even the big ones. Its scalability needs improvement. Stability for it should also be improved."
"The support needs improvement."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"We would like tenant segmentation available in future releases."
"I would rate NSX's stability eight out of ten - there's room for improvement."
 

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 price is significantly high and it can be a hurdle for many potential users."
"We are using the free version of the solution."
"This solution requires a licence."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"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."
"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 pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"We are using a perpetual license to use the solution and we have support."
