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.

Offers bot protection and DDoS Protection and protects public-facing portals
Support is one thing I wish Imperva could improve. They follow the phone model and keep rotating you from one customer service person to another. The layer one support isn't very clear about the workings of the product. My feedback is primarily about Imperva Cloud, not on-premise. On-premise is a whole new story. Support is the issue for Imperva Cloud. It's also a bit pricey. It's a premium service and very expensive. The licensing model is not very straightforward. Every feature is priced separately, and to enjoy maximum protection, you'll have to spend a lot of money. The licensing model is a bit complex, and each feature is very pricey. For example, API security and web application protection are two separate license packages.

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."
"The most valuable feature is its usability."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"New and innovative way to protect the client's data."
"The solution provides good load balancing and protection against DDoS attacks."
"The solution is stable, and the DNS servers are simple to use."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"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."
"It blocks all types of attacks."
"The most valuable features are DDoS protection."
"It is a stable solution."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"The solution has a very good interface."
"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."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"Imperva Web Application Firewall is stable."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"It mitigates all of the availabilities of risks around web applications."
"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."
"There is a quick switch between any of the the nodes if something goes wrong, where there's a there's an attack against a specific area. The security setup is reasonably easy. It's not a problem to do setups and rules and integrations. And, yeah, just the the back end team is also very willing to insist if there's questions that that we cannot answer or with these questions that we do have"
"The solution can be configured in just a couple of minutes."
"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
"It works right out of the box once you integrate the application."
 

Cons

"There should be a specific price list for enterprise-level customers."
"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"An integrated SSO feature would be useful for Cloudflare DNS."
"The analytics, basically the dashboard, doesn't have much to it."
"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 integration of LLMs on the dashboard is something that is needed in the tool."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"The rules surrounding the making of web applications could be improved."
"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."
"We had an issue when securing the web applications for DDoS protection."
"Imperva DDoS does not provide version control."
"The solution should integrate with something that looks at continuous security management."
"Some maintenance must be performed by our IT team."
"Imperva should have more points of presence in Africa."
"It's quite expensive."
"One potential improvement for Imperva is enhancing its alert system."
"There could be some limitations that from the converged infrastructure perspective: when you want to converge with everything and you want Imperva to get there easily because it's not a cloud component. For example, when you want to build servers and you're using OneView to manage your software-defined networks, implementing Imperva right away is not that simple. But if you're doing just a simple cloud infrastructure with servers in there, you're good to go. Also, we are not able, with Imperva, to block by signatures. Imperva by itself needs to be complemented with another service to do URL filtering."
"Sometimes our web application firewall will slow down."
"It's a complicated tool to keep."
"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"Sometimes, support tickets don't get addressed quickly."
"Imperva Web Application Firewall can improve by providing better features, such as improved prevention of zero-day attacks. Additionally, it should include a VR meta-analysis."
 

Pricing and Cost Advice

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"A free version of the solution is available."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"The product's pricing is cheap."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The tool is a premium product, so it is very expensive."
"I give the price a five out of ten."
"There are no additional costs beyond the standard licensing fees."
"The license is on a yearly basis."
"Pricing could be more competitive."
"Varies depending on the needs of the customer."
"We are satisfied with the pricing."
"It is not expensive compared to the other similar solutions in this category."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"Everybody complains about the price of this solution."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
"There is a license for this solution and we purchase the license annually with no additional fees."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"Imperva Web Application Firewall is expensive."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
