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.

Effect local attack handling, intuitive interface, and scalable
The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution.

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.

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 fast and secure DNS."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The technical support is good."
"The most valuable features of the solution are performance and security."
"Centralized, full-featured DNS."
"The solution offers the flexibility to control configuration rules."
"It's very user-friendly."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"This is a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"The DDoS protection features are valuable."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"On the real time, you can see live traffic, which is flowing into our website."
"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."
"The solution has a very good interface."
"​Technical support provides good, quick responses."
"This product is a reliable defense from malicious attacks on a network environment."
"The complete solution is valuable for everything it delivers and the protection it offers."
 

Cons

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"The pricing could be improved."
"The solution could work at being less expensive. It costs a lot to use it."
"The product support needs to be accessible from more places, a wider area of coverage."
"Cloudflare's console should be made more user-friendly."
"Support response time could be improved."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"The product must provide more Layer 7 capabilities."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"It could use support in Spanish."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"I miss being able to integrate the dashboard with other BI tools we are using. We have to export and import data to be able to present it, and doing so is a lot of work."
"It's quite expensive."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"A limited tool if you're looking to customize."
"It would be beneficial to include vulnerability management in the solution, similar to what they have for their on-premise solution."
"Pricing can be improved, as it is quite expensive."
"There’s nothing that’s missing in terms of features."
"The product could use a broader scope in the area of policies."
 

Pricing and Cost Advice

"I give the price a five out of ten."
"There are no additional costs beyond the standard licensing fees."
"The cost primarily depends on the size of the organization."
"We are using the free version."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We are using the free tier of the solution."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"Its price is normal."
"The price of Corero is affordable."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"There is a license or subscription renewal that our customers pay."
"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."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"It is not expensive compared to the other similar solutions in this category."
"The license is on a yearly basis."
"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."
