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

"We use the product to prevent unauthorized access to data, systems, and servers. It provides essential features for data center security."
"The real strength lies in its straightforward approach, offering just two key policies: prevention and detection."
"We have not reduced manpower, the number of servers has gone up, but the number of incidents has tricked down to single digits."
"The tool will then detect any anomalies, such as an intruder who has breached the network, which can trigger the system lockdown feature if it's enabled and meets the defined threshold."
"The most valuable feature is the endpoint protection system."
"Overall, this is a pretty good product."
"The file integrity monitoring features are the most valuable features of this product."
"The advantage of Data Center Security is its ease of use and that it serves as a single unified platform, where I can apply all my security policies to protect that server."
"The feedback we're getting from the labs is that the stability is rich and that we haven't had any trouble with it."
"The most valuable features are ease of use and user interface."
"Some of the key features I find most valuable are the highly graphical user interface, virtualization of networks, and Microsoft application compatibility. It has all the functionality that we require."
"You're building a scalable solution, a secure solution, and a stable end-to-end solution; these are the main measurable benefits VMware NSX provides to the users."
"NSX has excellent security features like virtual firewalls. I also like the micro-segmentation features, which are useful for the virtual machines inside the servers."
"The solution is robust as it covers everything we want to do and is stable, so we're happy enough with it. We have had no problems so far. Everything is great."
"I can definitely recommend VMware NSX to other users."
"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."
 

Cons

"The support is very bad. They're not fast at all. Trend Micro's support is much better."
"It would be advantageous if Symantec or Broadcom, given the rebranding, could simplify the process, enabling users to leverage the antivirus functionality more easily."
"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."
"A user or administrator making the policy in the DCS should have a very thorough knowledge of the operating system or policy making. You have to be very specific about the data structure."
"Agent management is a challenging task."
"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."
"I would rate NSX's stability eight out of ten - there's room for improvement."
"I would rate this product an eight because it's a good product but it needs more work. They should fix some of the bugs."
"The next release of NSX should try to make Kubernetes and container integration a little easier than it is now. It's quite a complicated process."
"Sometimes we face issues when a server is compromised or we have an infection. The isolation feature helps, but we need to work more on this aspect."
"If an organization is not able to use NSX to its full potential (Switching, Routing, Load-balancing, Firewall, IDS, IPS etc.) then its not worth it."
"Despite being somewhat behind in the cybersecurity field, VMware should develop a cloud and a red team to continuously monitor for new malware and ransomware."
"There could be an improvement in regards to security."
"The network-extending capabilities for the physical environment need improvement."
 

Pricing and Cost Advice

"The product is a bit costly."
"Compared to some other solutions, such as CrowdStrike, Symantec is more expensive."
"It is notably more expensive when compared to other solutions."
"There is a license required for this solution, we pay annually."
"We have saved man-hours and decreased our security exposure."
"We are using the free version of the solution."
"The price of VMware NSX is very good compared to other solutions."
"The cost of the solution is a bit high."
"The price of this product is too high."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"We haven't had to hire a dedicated network engineer because NSX handles 90 percent of it. The reduced overhead in terms of managing networks has been the biggest plus."
