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.

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 tool helps with my company's security posture."
"I would recommend Illumio to all sizes of companies."
"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 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 solution is easy to use."
"The Explorer allows you to know the traffic between source and destination."
"It has helped us to understand internal network visibility and firewall policy implementation. We use the product to simplify firewall policy implementation."
"They have a lot of support and specialists who can meet with the customer."
"The most valuable features are stability and low cost."
"This is a good firewall and overall it is rich in features."
"The microsegmentation allows me to sleep at night. My job is reducing risk, plugging security holes, and working with the automated layer security. Even if somebody spins up a new server, it has to have a tag in NSX."
"Provides protection for virtual machines."
"From a security standpoint, the customer was able to better secure critical workloads while routing L2/L3 worked normally, giving them more confidence that they would be ready for any potential security incident mitigation or outage (DR)."
"Any administrator with basic networking knowledge, in a couple of days, can be in full control of their networking without going through a networking engineer."
"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."
 

Cons

"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"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."
"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. 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."
"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."
"The solution is complex but for the key user, it's not really complex. You just need to learn the standards and mechanics for your specific product."
"Their licensing model should make it easier to purchase licenses."
"The tool's setup is complex and we need support to implement it."
"The setup of the solution could be simplified."
"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."
"VMware NSX can improve the migration tools from the older environments to the new environment. For example, the NSX-V has become a legacy solution, it's out of support, but customers are able to keep using it. For migration purposes, it's better for them to provide a proper tool. It will be easy to migrate from an old environment to a new one."
"We would to have a reverse proxy. This would add great value to the solution."
"If there are other solutions already in place, it can be difficult to implement."
 

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."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"We can't go without NSX, so it's invaluable from this perspective."
"We are using a perpetual license to use the solution and we have support."
"There is a license required for this solution, we pay annually."
"The cost of the solution is a bit high."
"The price of VMware NSX is optimal. Additionally, the price of the solution can be negotiated with the vendor. Many areas of the solution can impact the cost, such as features, time for onboarding, and support needed."
"The price of VMware NSX is reasonable."
