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

"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The most valuable feature is the web application firewall."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"It's very user-friendly."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"Integration with IBM AS/400 and Db2 is okay."
"On the activity log, I can see the exact details, the visit, and the threat."
"The dashboard is good and user-friendly."
"The solution is very good at intercepting traffic before it gets to our data centers."
"It's very pretty easy to onboard the URL."
"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."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"We really like the performance of this solution."
"The most valuable feature that I found is the load balancing feature, it is the core function of the product."
"I like that this is a Network Load Balancer that can be used practically with any application in the backend. They have how-to guides on how to set up Kemp NLB with Exchange, but you can use it as well for Sharepoint, RDS, or any other back end server."
"The solution is easy to configure when changing the load balancing method to Round Robin or least connection."
"The most valuable feature is the load balancing and allowing for high availability of our web services."
"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."
"The base feature of Kemp LoadMaster load balancing ticks all the boxes but the most valuable features would be the security features Intrusion Prevention (IPS) and Web Application Firewall (WAF)."
"There is a simplicity to the setup and configuration."
 

Cons

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"The documentation could improve for Cloudflare DNS."
"There are some issues with the CDN services."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"Latencies are always a problem."
"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 salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"Some maintenance must be performed by our IT team."
"There’s nothing that’s missing in terms of features."
"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."
"The rules surrounding the making of web applications could be improved."
"Its price could be improved. It is quite expensive. It will be good if we could export the configuration. Currently, to control the configuration, we need to go to each website, which is not very convenient."
"Imperva should have more points of presence in Africa."
"We have experienced at least one problem with stability, although it was fixed with an upgrade."
"The product could be improved by making the SSL Offloading easier."
"Perhaps Kemp could offer some training videos."
"There is room for improvement in the stability of the solution."
"It would be helpful if there were a way to incorporate tooltips on the fields so that we don't have to dig through documentation."
"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."
"When we go serverless, we may again have to revisit this because the configuration needs to be changed. With this change, we can run into a lot of other configurations that we haven't got into, which involve additional expenses. It would be challenging to convince management to buy at that price point. It would be a balancing act of justifying that expense and the value, that is, how it is going to save a bit of time and make our platform secure. It can have better configuration ability. A lot of iterations happen when we have multiple servers pointing to the same domain. If we do not orchestrate carefully, it gets into a loop, which takes away the precious time of the user who is trying to subscribe to a service. It takes a little longer time to realize services as well as web pages."
"It would be much easier to have the management interface directly integrate with the Kemp Support library, allowing you to choose the desired template from the online catalog to then directly download to the LoadMaster."
 

Pricing and Cost Advice

"The product's pricing is cheap."
"We are using the free tier of the solution."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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."
"There are no additional costs beyond the standard licensing fees."
"The tool is a premium product, so it is very expensive."
"The price is reasonable."
"The license is on a yearly basis."
"The solution's price is high for small companies."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"Varies depending on the needs of the customer."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"We are satisfied with the pricing."
"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."
"The Kemp LoadMaster is a tremendous value."
"This is a cost-efficient product."
"The price is lower than other options."
"​I have control on the licensing and all the prices since I work for a partner.​"
"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."
"It has a great price for the solution they offer."
"The pricing is alright and we pay a monthly licensing fee"
