Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Yazan Omar - PeerSpot reviewer
An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Enhanced security and streamlined management drive efficient connectivity
Open source is a standard solution where you take a gray box or white box and put the software from your end. You can do programming with Ansible and make the network work in the software-defined mode, providing automation and management capabilities. I am currently working with VMware. It integrates easily with everything and can work with any system. When discussing micro-segmentation, it enhances security, providing more secure data in your data center while allowing for extra layers of security outside your data center. If you have an ACI, there is communication between locations, keeping your data secure in your data center and throughout the path it takes, such as to SD-WAN or the cloud. I work with cloud solutions including AWS, Azure, GCP, and private cloud. My overall rating for VMware NSX is 8.5 out of 10.

Quotes from Members

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

Pros

"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"The solution is very good at mitigating threats."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"Cloudflare has many features."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The most valuable feature is the cloud DDoS scrubbing capability."
"Packet inspection has been effective for mitigating DDoS attacks."
"The product allows the users to adjust the thresholds."
"I find the interface easy to use."
"It is a user-friendly product in terms of monitoring and updating policies."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The solution is very user-friendly and very easy to use."
"It allows me to see all the traffic on my network."
"It is a stable solution...The solution's initial setup process was easy."
"The installation is straightforward, it took a couple of hours."
"The most valuable feature of VMware NSX is the ability to set up virtual networking environments."
"VMware NSX offers some of the best features for security, such as micro-segmentation."
"Firewall security is one of VMware NSX's vital features"
"The microsegmentation allows me to sleep at night. My job is reducing risk, plugging security holes, and working with the automated layer security. Even if somebody spins up a new server, it has to have a tag in NSX."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided."
 

Cons

"The pricing could be improved."
"The documentation could improve for Cloudflare DNS."
"The product support needs to be accessible from more places, a wider area of coverage."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"DNS Management."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Cloudflare should add more documentation and pricing to the cloud version."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"I would like to see analytics, big data."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The web interface could be much better."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"Alerts and reporting features must be improved."
"Everybody needs a network to connect to, and VMware doesn't readily provide one."
"The scalability is not perfect."
"VMware NSX only supports some platforms like KVM."
"The initial configuration and integration within our existing environment were not easy. The configuration process was a bit complex, specifically during the initial setup."
"Their licensing model should make it easier to purchase licenses."
"The ticket support response time from VMware could be improved. Often, callbacks are delayed, which can be problematic if the servers are in production."
"Its licensing model could be VM based."
"The support from VMware NSX could improve."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We are using the free version."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The price is reasonable."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The solution is reasonably priced."
"The product’s pricing needs improvement."
"It's quite pricey."
"I would rate the pricing of VMware NSX as seven out of ten"
"The price of VMware NSX is reasonable."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"We are using the free version of the solution."
"We can't go without NSX, so it's invaluable from this perspective."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The pricing model for VMware NSX is good."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
