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

"Symantec Data Center Security, as a name, represents the perfect solution if you want to harden your servers."
"The console and tools are very user-friendly."
"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 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 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."
"We use the product to prevent unauthorized access to data, systems, and servers. It provides essential features for data center security."
"Overall, this is a pretty good product."
"The most valuable feature is the centralized console, which can handle different products that we have."
"VMware NSX is a stable solution; it's very reliable."
"The most valuable features for us at this early stage are the interface and the integration with existing VMware solutions."
"We can see the flows inside the SDN, which has a lot of power."
"The solution is great for controlling virtual switches and it is easy to establish VLANs and micro-segmentations."
"NSX has excellent security features like virtual firewalls. I also like the micro-segmentation features, which are useful for the virtual machines inside the servers."
"Has a great firewall."
"NSX's stand-out function is the distributed firewall. The firewall system is just top-notch, and I haven't seen another solution like it."
"The microsegmentation is great, and the security team thinks it is great."
 

Cons

"Could have better reporting capabilities and better support."
"Symantec is lagging on the reporting side."
"The support is very bad. They're not fast at all. Trend Micro's support is much better."
"Agent management is a challenging task."
"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."
"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."
"Some configuration maximums are limiting to the user, especially when it comes to the deployment of very, very large environments."
"If you compare NSX to a similar solution you might find it to be a bit more complex."
"We had some complexities implementing into the other parts of a network."
"In the future, the solution should be compliant with internet NIC."
"It could be cheaper!"
"VMware NSX provides a lot of automation capabilities, but there is still room for improvement."
"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."
"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."
 

Pricing and Cost Advice

"The product is a bit costly."
"Compared to some other solutions, such as CrowdStrike, Symantec is more expensive."
"It is notably more expensive when compared to other solutions."
"The solution is very 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."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"The licensing fees are expensive and we pay on a yearly basis."
"The subscription is on a yearly basis."
"The price of VMware NSX is very good compared to other solutions."
"The price is significantly high and it can be a hurdle for many potential users."
"I would rate the pricing of VMware NSX as seven out of ten"
