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.

Micro segmentation has strengthened zero trust security and isolates production from test environments
The advantages of VMware NSX include its micro-segmentation for internal security at the firewall and VM levels, which is very powerful and helps us comply with complete Zero Trust security models. We are able to achieve this and configure network level virtualization with no dependency on VLANs. Micro-segmentation helps improve our security significantly. We are not totally dependent upon our physical upfront firewall, and it makes sense to configure everything using VMware NSX, leading to multiple improvements in our organization. We moved from traditional networking such as VLANs from the firewall and switches to VMware NSX segmentation. We achieve one firewall per VLAN and can stop lateral movement such as ransomware control. The Zero Trust model is the main functionality and architecture it offers, allowing application isolation, such as having a separate production and test environment. Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Overall, this is a pretty good product."
"The most valuable feature is the endpoint protection system."
"Good file integrity monitoring features."
"We use the product to prevent unauthorized access to data, systems, and servers. It provides essential features for data center security."
"The most valuable feature is the centralized console, which can handle different products that we have."
"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."
"The ability to finely control permissions and restrictions on servers or assets through a customizable rule set is a key strength."
"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 most valuable features are its security aspects, especially the IPS and IDS for intrusion detection and protection."
"The most valuable features are security and dynamic routing."
"Technically, VMware NSX is more advanced technology-wise when compared to others. We have been studying it and so far, so good. We know that the NSX product is superior when it comes to software virtualized networks. </p> <p>If you are looking to work with new and future technologies, then NSX is one of the best options. It costs less for power consumption since it will be a virtual network and not a pure physical network that consumes more energy."
"We like that everything is integrated."
"The initial setup was straightforward. You just have to click it and follow the manuals."
"It's changed the way we do things."
"When you're talking about virtual networks, I think NSX is one of the greatest products and will soon be the leader in the market."
"Visibility, because on our environment, it's impossible mapping end to end, and we don't have any tools that provide this integration."
 

Cons

"Could have better reporting capabilities and better support."
"Since the acquisition of Symantec, our customers have not been satisfied with this solution."
"Symantec is lagging on the reporting side."
"Agent management is a challenging task."
"The support is very bad. They're not fast at all. Trend Micro's support is much better."
"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 plenty of room for improvement with this product, and it could start with platform metrics."
"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."
"We would like tenant segmentation available in future releases."
"Lastline is not a cheap product if compared with their competitors."
"The scalability is not perfect."
"Migrating from V to T is very tricky, complicated, and there are a lot of parameters to account for."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"We would to have a reverse proxy. This would add great value to the solution."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"The routing functionality needs to be improved, as there are lots of bugs in the system."
 

Pricing and Cost Advice

"The product is a bit costly."
"It is notably more expensive when compared to other solutions."
"Compared to some other solutions, such as CrowdStrike, Symantec is more expensive."
"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."
"The subscription is on a yearly basis."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"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."
"VMware has always been geared towards enterprise and their pricing options are a bit high. Their price is higher than other options in the market."
"We are using a perpetual license to use the solution and we have support."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
