It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

I like the content monitoring feature which I haven't seen in other WAF solutions.
They could improve by minimizing false positive results. Although this occurs less with Imperva, we would like to see some further improvements. We have been using this product for last 1 years, it's result is very impressive. But due to the excessive load on the Web site where thousands of requests‎ are generated from legitimate users, however the request in which any sequential or specialised characters are requested would be directly blocked by impreva . Currently imperva blocks the special character request generated from the user, as I conduct a test where I am parsing the encoded html values of the same special characters to the input field, imperva bypasses these encoded values for example : ' i.e. %27 or / i.e %2F, the WAF bypasses these encoded characters. I hope that this device should have a capability to detect the pattern which is associated with Xss or Xsrf, rather then by not blocking the request which contains any special characters.

A highly stable and scalable load-balancing software that offers great technical support
My company is really happy with Kemp LoadMaster as a product. My company is also happy with the support we receive from Kemp LoadMaster. I want Kemp LoadMaster to provide users with better reporting capabilities in relation to TCP packets. In general, the connections that are present in the system require improvement. Feature-wise, Kemp LoadMaster has everything that our company's customers require. Kemp LoadMaster also has features that have supported our company's past projects.

Quotes from Members

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

Pros

"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"From what I've seen so far, there are no negatives to report as of yet"
"I like Cloudflare's application gateway and DDoS protection."
"The technical support is good."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The UI is good."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"Imperva DDoS is fairly stable, and its availability is quite high."
"The most valuable features are DDoS protection."
"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."
"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."
"It fits our requirements, as well as our budget."
"I like the user-friendly interface."
"Load-balancing is a great feature that is very easy to configure and it is always working fine."
"The most valuable feature that I found is the load balancing feature, it is the core function of the product."
"We really like the performance of this solution."
"Persistence is very valuable. This holds the connection information of the source and that connection is important to RDP and our APO calls. The connection has to be persisted to the original source to operate properly. We also use the subsections for sub-services to create services inside our services for our API resources, this is most awesome. We would not be able to do this without Kemp and offer this type of sub-service to route based on an API instance. It routes the traffic properly based on the sub-service type."
"The solution is easy to configure when changing the load balancing method to Round Robin or least connection."
"The feature that allows us to easily disconnect a server when we need and bring back online is the most valuable. It's a click of a button. This allows us to keep all systems up. We can then run updates, perform reboots whatever we need to one of the servers without taking production down."
"From my personal experience, many firewalls provide Load Balancing functionalities, but Kemp Loadmaster has a lot of features and functionalities like what you can configure. So there are a lot of features but we use only five percent of it."
"The configuration is really easy and the web portal is self-explanatory."
 

Cons

"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"Latencies are always a problem."
"An integrated SSO feature would be useful for Cloudflare DNS."
"The documentation could improve for Cloudflare DNS."
"There should be a specific price list for enterprise-level customers."
"Pricing can be improved, as it is quite expensive."
"I would like to have support for SSL management and secure DNS."
"Certificate management could be improved."
"There’s nothing that’s missing in terms of features."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"We had an issue when securing the web applications for DDoS protection."
"Imperva should have more points of presence in Africa."
"Some maintenance must be performed by our IT team."
"If there is anything that needs to be updated, the GUI can get a refresh to make it look more like 2020, although it is just a cosmetic change."
"Although Kemp is very user-friendly, it lacks a more custom configuration."
"It would be nice if the historical metrics were easily exportable from the interface."
"They were still in the process of development, and for example, we set it up in a cluster. So it was one logistical unit built out of two physical devices. And the expected behavior, which I know from other devices, will be formed into a logic cluster. It's that you configure one unit. Then you bring the second unit into this cluster with the already configured primary unit. So the secondary box pulls all the configured ones from its neighbor, does everything automatically, and then synchronizes with this primary neighbor. And then it works, like, one logical unit. And this didn't work with the Kemp's initially, where they caused a lot of issues when building up a cluster, so there were some specials on how to set this up. When we built or set them up for the first time and the months afterward with no new software releases, there were a couple of problems, but in the end, they worked fine. So, they developed a lot and learned from what they've responded to, what we responded to them, and what needs fixing."
"I really don't like the way the logs are presented in the software."
"It would be very helpful to get all the http/https session logs by default in the log monitor without activating debugging mode like an apache web sever natively does"
"In my opinion, the layer seven loads balancing that we're mainly using for web servers, doesn't seem to pick up when there are issues at the application level."
"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking."
 

Pricing and Cost Advice

"The price of the solution is expensive."
"The product's pricing is minimal compared to other products."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"A free version of the solution is available."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"The solution's price is high for small companies."
"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
"The license is on a yearly basis."
"It is expensive."
"It is not expensive compared to the other similar solutions in this category."
"Varies depending on the needs of the customer."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"KEMP gives away free trials for 30 days. This can be stretched if you want. During the test, you will have access to KEMP support.​"
"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."
"Download Kemp's VLM trial and take it for a test drive; you will be impressed."
"Less expensive than Citrix."
"This is a cost-efficient product."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"The price is great and the value is definitely there."
"Currently, no cost is involved with a virtual load balancer. They have used open source. We did not pay for software. We paid for the expertise. We are only paying the consulting charges, which are very reasonable, that is, around a thousand dollars."
