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 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 granularity of applying the policies is valuable."
"The ability to finely control permissions and restrictions on servers or assets through a customizable rule set is a key strength."
"We use the product to prevent unauthorized access to data, systems, and servers. It provides essential features for data center security."
"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."
"Good file integrity monitoring features."
"We have not reduced manpower, the number of servers has gone up, but the number of incidents has tricked down to single digits."
"The most valuable feature is the centralized console, which can handle different products that we have."
"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."
"Though I haven't been working a lot on VMware NSX, it's good to have. What I like the most about it is that its console is good, and it doesn't take a lot of effort in terms of doing my daily tasks on it or what it's meant for. VMware NSX is still a preferred product in the market."
"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."
"The most valuable and unique feature of the solution is Micro-segmentation achieving better security, through enabling security architects to divide data centre into different segments, one being the VMS within the on-premises, the other one on the Cloud."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"VMware NSX is used for micro-segmentation, and if you have a virtual VMware pool then you can segment them separately, similar to a firewall for virtual micro-segmentation."
"The migration methods are the most valuable aspect of this solution."
"NSX can reduce costs and has good service. It is easy for you and your users to use."
 

Cons

"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."
"The product blocks certain processes, even after allowlisting them."
"There is plenty of room for improvement with this product, and it could start with platform metrics."
"Symantec is lagging on the reporting side."
"Agent management is a challenging task."
"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."
"There is room for improvement in enhancing its graphical user interface for a more user-friendly experience."
"It would be advantageous if Symantec or Broadcom, given the rebranding, could simplify the process, enabling users to leverage the antivirus functionality more easily."
"The support from VMware NSX could improve."
"The solution is quite complex."
"However, they should provide better documentation."
"In the next release, they should enhance the visual interface."
"It could be more user-friendly, but it's manageable. When we add a specific node to this particular NSX and the configuration changes, it won't push through the errors where required, but it'll accept it. However, while using it, we will have issues. It can also be more stable."
"vRNI Improve integration with many third-party solutions, because only Palo Alto and Check Point, and VMware would be like improve this integration with other vendors."
"VMware NSX can improve the migration tools from the older environments to the new environment."
"It takes time to do the initial setup. It is a bit slow, which is surprising."
 

Pricing and Cost Advice

"Compared to some other solutions, such as CrowdStrike, Symantec is more expensive."
"The product is a bit costly."
"It is notably more expensive when compared to other solutions."
"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"The solution is reasonable at the local level."
"The price of this product is too high."
"We have saved man-hours and decreased our security exposure."
"It is an expensive product, but cheaper than some competing solutions."
"All the institutions have to pay monthly for the services in the cloud. They have to pay $30,000 every month for this service every three years."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
