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 most valuable feature is the centralized console, which can handle different products that we have."
"The console and tools are very user-friendly."
"The granularity of applying the policies is valuable."
"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."
"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."
"Symantec Data Center Security, as a name, represents the perfect solution if you want to harden your servers."
"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."
"The alert features are the most valuable."
"The most valuable features of VMware NSX are the tight integration with the VMware Hypervisor natively and the management console. We have a lot of other integrations where you are able to see the virtual machine's end-to-end visibility."
"It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers."
"I really like the management dashboard, the tailor-made assurance, the telemetry, and the ease of integration with all other solutions of VMware, such as vSphere."
"Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack."
"NSX gives us the ability to put our network, NSX, onto any network there is, which allows us not to have to go to the network team to create networks our VLANs for networks."
"The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw."
 

Cons

"Adding more compatibility with common products like Microsoft would be a plus."
"There is plenty of room for improvement with this product, and it could start with platform metrics."
"This solution clashes with Microsoft defender, which results in performance degradation on the machine."
"Symantec is lagging on the reporting side."
"Could have better reporting capabilities and better support."
"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."
"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."
"The technical support could use some improvement."
"VMware NSX provides a lot of automation capabilities, but there is still room for improvement."
"Lacks integration with other solutions."
"Some configuration maximums are limiting to the user, especially when it comes to the deployment of very, very large environments."
"They have some limitations in the firewall features as compared to the on-prem or dedicated hardware appliance. They can add more features, such as IPS and IDS, to the cloud firewall."
"Going through and getting more features sets from the routing protocols is definitely necessary for the future."
"I would rate NSX's stability eight out of ten - there's room for improvement."
"We would to have a reverse proxy. This would add great value to the solution."
 

Pricing and Cost Advice

"It is notably more expensive when compared to other solutions."
"The product is a bit costly."
"Compared to some other solutions, such as CrowdStrike, Symantec is more expensive."
"It is an expensive product, but cheaper than some competing solutions."
"VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy."
"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."
"We can't go without NSX, so it's invaluable from this perspective."
"The price is pretty high."
"The solution is very expensive."
"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."
"We are using the free version of the solution."
