VMware NSX and Illumio compete in the network security and micro-segmentation category. Illumio seems to have the upper hand due to its ease of use and deployment, which can be beneficial in dynamic environments.
Features: VMware NSX provides a comprehensive suite for managing and securing data flows within virtual networks, emphasizing scalability and seamless integration. The micro-segmentation feature is highly praised and enhances security when a robust network foundation is present. Illumio offers visibility and simplicity in managing micro-segmentation without network changes, reducing complexity in dynamic environments. It simplifies security policies and application traffic visualization, ideal for straightforward deployment.
Room for Improvement: VMware NSX faces challenges with complex upgrade processes and integrations, such as with Kubernetes and legacy systems. Users have noted the need for enhanced reporting and simpler licensing. Illumio could improve compatibility across operating systems and better support environments with unique devices like industrial sensors. Additionally, refining data security features and providing interactive support sessions could enhance user experience.
Ease of Deployment and Customer Service: VMware NSX offers strong technical support but is recognized for complex deployment, especially in large-scale or hybrid cloud environments. Illumio is generally easier to deploy and effective in straightforward on-premises and public cloud setups, with positive support ratings and some feedback on needing enhanced proactive service.
Pricing and ROI: VMware NSX's pricing is considered high, which may deter smaller organizations. Despite its significant ROI by optimizing infrastructure, upfront costs and complex licensing can be barriers. Illumio is seen as more cost-effective with a flexible pricing model suitable for different operation scales. Its affordability is appreciated, albeit with initial implementation costs being an investment. Both solutions are noted for significant ROI through improved security and network management.
I observe extensive return on investment with Illumio.
Illumio serves as a single endpoint technology where I can implement various features, including a zero-trust network, north-to-south and east-to-west configurations, and micro-segmentation, all coming from one platform, which ultimately saves us time and money.
Illumio definitely demonstrates its value in money-saving capabilities, enhancing our lateral environment inside the organization and providing effectiveness overall once integrated.
Whenever I raise a case with their support team, regardless of the priority level—P1, P2, P3, or P4—they generally reply within an hour
Even if we raise an issue on non-working days like Saturdays or Sundays, we receive prompt responses.
The customer support is very prominent.
They were always helpful.
They are quick and understand things easily, so the support is aligned very effectively.
Our technicians have a good support experience from the company.
Scaling it to a large level is not an issue for us.
By employing Linux scripting or other methods, I can push the policy to all devices at once, making it easy to scale.
Illumio's scalability is very good; it is quite easy to scale.
There is a high level of satisfaction with its ability to scale.
Illumio is a stable solution with no glitches or bugs reported, making it a reliable product for us.
The product performs at 99% efficiency without any showstoppers or significant issues.
For stability, I would rate VMware NSX as a nine out of ten.
They need to install an agent in the container world, while Akamai Guardicore does not need to install an agent, so they have native support that Illumio lacks.
There could also be more examples of how the automations can be done using Illumio.
Another improvement might be around scalability, ensuring that as organizations grow, Illumio can handle even larger, more complex environments seamlessly.
The initial configuration and integration within our existing environment were not easy.
The pricing for the product is another area for improvement as I'm not satisfied nowadays.
The licensing model is expensive and could be more flexible, especially after Broadcom bought VMware.
I know that Illumio is the cheapest solution in the security area.
But when you compare it to firewalls, then it may not be that expensive.
I think it's not very expensive if we compare it with Guardicore.
The cost of VMware NSX is considered high.
The complexity is too high in terms of price.
VMware NSX is a little higher in price compared to the competition.
Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.
The most important feature is the traffic review analysis, where we use the draft view and the reported view that helps us understand how the application interacts with other applications in the environment, and based on that, we are able to define the policies.
Illumio is a powerful tool for micro-segmentation and zero trust security that provides strong visibility, flexible policy management, and effective threat containment, enhancing an organization's internal security posture.
Micro-segmentation enhances security and provides more secure data in your data center.
Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations.
The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with.
