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.

Deployment is simple. Machine learning techniques lower the false-positives alerts rate.
The use of a WAF becomes especially relevant in the case of concrete vulnerabilities, such as those uncovered via penetration tests or source code reviews. Even if it were possible to fix the vulnerability in the application promptly and with a reasonable amount of effort, the modified version can generally only be deployed at the next maintenance interval; often 2-4 weeks later (a patch dilemma). For a WAF with whitelisting, vulnerabilities can be fixed promptly (hotfix) so that they cannot be exploited before the next scheduled maintenance. WAFs are especially fast in this aspect, meaning they can collaborate with source code analysis tools, so that detected external vulnerabilities can automatically result in a recommended rule set for the WAF. A WAF is particularly important in securing productive web applications which themselves in turn consist of multiple components and which cannot be quickly changed by the operator; e.g., in the case of poorly documented applications or regarding third-party products without sufficient maintenance cycles. A WAF is the only option for promptly closing external vulnerabilities.

Quotes from Members

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

Pros

"It is easier to configure and develop documentation to see how we have configured firewalls."
"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."
"Centralized, full-featured DNS."
"The most valuable feature is its usability."
"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."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"It's very user-friendly."
"It is a stable solution."
"This product is a reliable defense from malicious attacks on a network environment."
"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."
"Integration with IBM AS/400 and Db2 is okay."
"An improvement has been to our website: It increases the speed of our response, the capacity of the site, and optimizes the bandwidth.​"
"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."
"Simplifies putting everything in code."
"Imperva Incapsula has many valuable features. One, it protects the top 10 OWAS vulnerability, the open web application software platform, this is standard. Secondly, it protects against broken authentication. As well, it has remote execution of code."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
 

Cons

"Support response time could be improved."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"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."
"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."
"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."
"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."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"The product support needs to be accessible from more places, a wider area of coverage."
"Imperva now offers add-ons to add functionality, but I would like to see these included in the product, even if it would cost more."
"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."
"Analytics in the area of risk need to be improved to supply more information to the users for creating better environments."
"The product could use a broader scope in the area of policies."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"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 solution should integrate with something that looks at continuous security management."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
 

Pricing and Cost Advice

"A free version of the solution is available."
"The cost primarily depends on the size of the organization."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The price is reasonable."
"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 product's pricing is cheap."
"We are using the free version."
"Pricing could be more competitive."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"It is not expensive compared to the other similar solutions in this category."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"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."
"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."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
