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

"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."
"The tool is user-friendly."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"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."
"I like Cloudflare's application gateway and DDoS protection."
"The most valuable features for us are the DDoS and Bot."
"Gives us the ability to trace each connection, and to have logs to be able to differentiate between a positive and a false-positive intruder action."
"Integration with IBM AS/400 and Db2 is okay."
"The setup of Imperva DDoS was easy."
"Simplifies putting everything in code."
"I like the user-friendly interface."
"The dashboard is good and user-friendly."
"The three-second service level agreement is already better than the competition."
"The security features are the most valuable features of this solution."
"The solution is easy to configure when changing the load balancing method to Round Robin or least connection."
"We are most impressed with the ease of use and great support."
"Great web balancing and remote access balancing."
"Security is considered the most effective feature in Kemp LoadMaster."
"The user interface is very easy to work with."
"The configuration is really easy and the web portal is self-explanatory."
"The most beneficial function of using the ADC is to ensure this resiliency."
 

Cons

"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"DNS Management."
"The documentation could improve for Cloudflare DNS."
"The product needs to improve its automation."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Latencies are always a problem."
"Support response time could be improved."
"The product could use a broader scope in the area of policies."
"Imperva DDoS does not provide version control."
"Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution."
"The solution needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"The solution should integrate with something that looks at continuous security management."
"I would like to see automated reporting to improve visibility."
"Analytics in the area of risk need to be improved to supply more information to the users for creating better environments."
"Hardware version needs a dual power solution."
"The configuration of the basic services is pretty straight forward but for more complex solutions, there needs to be better documentation or knowledge base articles."
"Some of the support documentation seems to make assumptions that the person installing or configuring is experienced with the product or concepts."
"I really don't like the way the logs are presented in the software."
"The product is really good as-is out of the box. If there is one thing I would change is to have the license file not be coupled with the MAC address of the device. This is actually not really useful in a virtual environment where if you have a single VM with KEMP LoadMaster and you have not set up static MAC Address, if you, for example, recreate the VM and just load the disk file on a new VM it will get new MAC address and the NLB will not work as it will not see a proper license."
"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking."
"Third, the password history restriction needs improvement. For example, the password policy will restrict the user to always use a unique password combination. The password should not be reused for a minimum of three generations of passwords."
"I want to have the ability to pull a particular server. The DevOps portion was challenging for me, like if I needed to redirect from one IP to another URL. I needed to look that up, and the knowledge base is not well organized. When I look for information about Kemp on the Internet, I don't find many articles or something like that."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"The product's pricing is cheap."
"The price is reasonable."
"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."
"We are using the free tier of the solution."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"The data packages are higher than our needs so we end up paying for data that we don't use."
"It is expensive."
"The solution's price is high for small companies."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"There is a license or subscription renewal that our customers pay."
"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."
"Any decent product will cost money and if you want great support and a great product, then you will want to spend the money on it."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"The license varies according to the number of megabits."
"It has a great price for the solution they offer."
"This product has good value and features for the money."
"At $2,500 USD, this is absolutely a fantastic buy for the money!"
"From a cost perspective, Kemp is very competitive and is not hard to justify by any means."
