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 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."
"Symantec Data Center Security, as a name, represents the perfect solution if you want to harden your servers."
"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 real strength lies in its straightforward approach, offering just two key policies: prevention and detection."
"Overall, this is a pretty good product."
"When you have a solid secure solution between your on-prem and cloud solution, then you're in a safe place."
"The most valuable features are the micro-segmentation and integrated security options."
"The most valuable feature is the integration with the firewall."
"The stability is great. That's one of the things that we can quantify and leverage through NSX, because it's less complex. We have the availability to manage multiple things at the same time. You can identify problems before they manifest."
"We can see the flows inside the SDN, which has a lot of power."
"The solution is very good at micro-segmentation."
"The most valuable features for us at this early stage are the interface and the integration with existing VMware solutions."
"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."
 

Cons

"The support is very bad. They're not fast at all."
"Adding more compatibility with common products like Microsoft would be a plus."
"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."
"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."
"This solution clashes with Microsoft defender, which results in performance degradation on the machine."
"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."
"VMware NSX should be able to scale for different customers, even the big ones. Its scalability needs improvement. Stability for it should also be improved."
"An area for improvement in VMware NSX is that it uses up more resources and is heavy on the network. What I'd like to see in the next release of the solution is more automation."
"Everybody needs a network to connect to, and VMware doesn't readily provide one."
"VMware NSX could improve by having more compatibility with other none Window-based operating systems."
"One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality."
"There could be an improvement in regards to security."
"It isn't easy to deploy."
"Just being more knowledgeable about the different functions."
 

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 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 tool's pricing is reasonable."
"The solution is free and the price for the support can be expensive."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"We are using a perpetual license to use the solution and we have support."
"We are using the free version of the solution."
