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

"Good file integrity monitoring features."
"Overall, this is a pretty good product."
"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."
"We use the product to prevent unauthorized access to data, systems, and servers. It provides essential features for data center security."
"The ability to finely control permissions and restrictions on servers or assets through a customizable rule set is a key strength."
"The console and tools are very user-friendly."
"The granularity of applying the policies is valuable."
"VMware NSX is a great product for network virtualization, and it's great for enhancing security at the virtual machine level."
"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)."
"It works and it is powerful in terms of governance, telemetry, ease of use, and ease of deployment."
"The most valuable feature of VMware NSX is the ability to set up virtual networking environments."
"The solution is very good at micro-segmentation."
"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."
"It has reduced the number of people on the network team along with the system engineer involved in the security process, so it is valuable and we can't go without NSX, so it's invaluable from this perspective."
"The installation is straightforward, it took a couple of hours."
 

Cons

"Agent management is a challenging task."
"Since the acquisition of Symantec, our customers have not been satisfied with this solution."
"There is plenty of room for improvement with this product, and it could start with platform metrics."
"Adding more compatibility with common products like Microsoft would be a plus."
"There is room for improvement in enhancing its graphical user interface for a more user-friendly experience."
"This solution clashes with Microsoft defender, which results in performance degradation on the machine."
"They need to develop a more flexible product that can be scaled such that it fits well into a small business or a bigger, enterprise-level solution."
"Symantec is lagging on the reporting side."
"Lastline is not a cheap product if compared with their competitors."
"Since most people are very much used to physical networking, they find it difficult to use VMware NSX in the initial stage."
"VMware NSX can improve the migration tools from the older environments to the new environment."
"It should be more adapted to the physical side of network topology in order to prevent unavailability."
"The price is rather high."
"We've have had good and bad experiences with them. We don't always find them to be so impactful. Sometimes the support guy isn't so on top of resolving the issue and it can take a while to sort out."
"It might be nice to have more AI in the future."
"Pricing and licensing could be improved as we are a government entity."
 

Pricing and Cost Advice

"Compared to some other solutions, such as CrowdStrike, Symantec is more expensive."
"It is notably more expensive when compared to other solutions."
"The product is a bit costly."
"There is a license required for this solution, we pay annually."
"The tool's pricing is reasonable."
"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."
"We have saved man-hours and decreased our security exposure."
"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."
"We are using a perpetual license to use the solution and we have support."
"VMware NSX isn't cheap."
"The price of VMware NSX is very good compared to other solutions."
