Continuous server hardening has protected critical legacy workloads and simplified security control
Symantec is lagging on the reporting side. I have been working for 10 years and I have identified many gray areas. As a user protecting your infrastructure, you need to sell the value to your management. Management buys the tool for preventing threats, and it works for them. However, you cannot sell it because every solution needs to show what happened in the last few years or how you will be protected in the future. Reporting is the most important thing for the CIO level, not the admin level. I have seen Symantec really lag in this area. I am creating my own tool to build a dashboard to share with the CIO level because they want to know what happened last week, last month, and last year. These reports will tell you about activities. Symantec changed the licensing when Broadcom acquired the company. The question of who will provide support became unclear. Support has now changed and they are making money. I have seen that most of the time when you ask implementation questions, they do not answer you. If you have a problem, they give you a low-level engineer at the first level. This delays resolution. Support has to be better.

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The ability to finely control permissions and restrictions on servers or assets through a customizable rule set is a key strength."
"The granularity of applying the policies is valuable."
"The most valuable feature is the endpoint protection system."
"The monitoring in the management console allows us to find out what is going wrong, and it gets reports even before the user reports it."
"The real strength lies in its straightforward approach, offering just two key policies: prevention and detection."
"Overall, this is a pretty good product."
"Good file integrity monitoring features."
"The console and tools are very user-friendly."
"VMware NSX has improved our customers' organizations through its automation of security policies, delivery of policy by intent, rapid provisioning, and removing security as being a blocker."
"This is the most scalable product of its type."
"The most valuable feature is the integration with the firewall."
"The most valuable feature of VMware NSX is the high bandwidth."
"When you're talking about virtual networks, I think NSX is one of the greatest products and will soon be the leader in the market."
"When using for K8s container platforms or a networking backed for on premises cloud using a CMP(VRA, VIO) then VMware NSX is the best SDN solution."
"The most valuable features are stability and low cost."
"The installation is straightforward, it took a couple of hours."
 

Cons

"There is room for improvement in enhancing its graphical user interface for a more user-friendly experience."
"The product blocks certain processes, even after allowlisting them."
"It would be advantageous if Symantec or Broadcom, given the rebranding, could simplify the process, enabling users to leverage the antivirus functionality more easily."
"This solution clashes with Microsoft defender, which results in performance degradation on the machine."
"Since the acquisition of Symantec, our customers have not been satisfied with this solution."
"Symantec is lagging on the reporting side."
"I think that technical support in general is not really capable of doing their work. They don't have enough knowledge to provide quick solutions, so we usually try to resolve problems within our team."
"There is plenty of room for improvement with this product, and it could start with platform metrics."
"If you compare NSX to a similar solution you might find it to be a bit more complex."
"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."
"It might be nice to have more AI in the future."
"Their licensing model should make it easier to purchase licenses."
"The network-extending capabilities for the physical environment need improvement."
"Going through and getting more features sets from the routing protocols is definitely necessary for the future."
"Speed of the NSX Controllers while deploying sometimes gets a bit slower which can be improved, overall its a great product"
"Migrating from V to T is very tricky, complicated, and there are a lot of parameters to account for."
 

Pricing and Cost Advice

"It is notably more expensive when compared to other solutions."
"Compared to some other solutions, such as CrowdStrike, Symantec is more expensive."
"The product is a bit costly."
"There is a license required for this solution, we pay annually."
"The price of VMware NSX is very good compared to other solutions."
"The cost of the solution is a bit high."
"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 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 product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"We are using the free version of the solution."
"The subscription is on a yearly basis."
