Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

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

"I find the interface easy to use."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"Packet inspection has been effective for mitigating DDoS attacks."
"The solution is very user-friendly and very easy to use."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The protection resources and the support are valuable features of the solution."
"The most valuable feature is the cloud DDoS scrubbing capability."
"This is the most scalable product of its type."
"The we can actually extend Layer 2 networking across datacenters, and also Layer 3 networking, which comes along with it."
"NSX is one of the simplest network solutions that I've ever worked with."
"NSX has improved our organisation in many ways, by securing it with micro-segmentation, and by allowing us to implement logical equipment in a matter of seconds instead of waiting for the physical material to implement and configure."
"VMware NSX has improved our organization in the way that we can now deploy many VMs faster than before and so we are scaling up much faster."
"I have found the system to be very intuitive, functional, and they have great technology."
"It is easy to implement it."
"The most valuable feature of VMware NSX is the ability to set up virtual networking environments."
 

Cons

"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The web interface could be much better."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"I would like to see analytics, big data."
"Alerts and reporting features must be improved."
"The product’s pricing needs improvement."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"The support needs improvement."
"The first time setting it up was difficult."
"NSX could better integrate with open-source products. Of course, it integrates with some, but I know many people are uncomfortable deploying NSX with certain open-source solutions, such as Radar."
"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."
"Sometimes we face issues when a server is compromised or we have an infection. The isolation feature helps, but we need to work more on this aspect."
"The vendor should integrate a basic load balancer in future versions"
"A room for improvement in VMware NSX is that it has some security vulnerabilities, which means my company has to apply the patches every once in a while."
 

Pricing and Cost Advice

"It's quite pricey."
"The solution is reasonably priced."
"The product’s pricing needs improvement."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"The price of VMware NSX is reasonable."
"We are using a perpetual license to use the solution and we have support."
"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."
"We haven't had to hire a dedicated network engineer because NSX handles 90 percent of it. The reduced overhead in terms of managing networks has been the biggest plus."
"The price is pretty high."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"There is a license required for this solution, we pay annually."
