Owner at Tech Exchange

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.

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

"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."

"Easier http to https redirect using page rules"

"It is easier to configure and develop documentation to see how we have configured firewalls."

"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 most valuable feature of Cloudflare DNS is its global reach and it is always evolving."

"Generally, I am satisfied with this product."

"It is a fast and secure DNS."

"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."

More Cloudflare pros

"Imperva Web Application Firewall is stable."

"The configurability of the tools and the ease of operation to be the most valuable feature of Imperva."

"Learning mode and custom policies are helpful features."

"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."

"The solution is stable."

"We can prevent attacks or issues even before they happen."

"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."

"Imperva monitors all traffic, even customer access, to the web application. Then, Imperva uses features like signatures to identify attacks like cross-site scripting or SQL injection."

More Imperva Web Application Firewall pros

"I would give Radware Kubernetes WAF a rating of 10 out of 10."

Cons

"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."

"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."

"There are some issues with the CDN services."

"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

"Support response time could be improved."

"Technical support is lacking."

"The solution could be more user-friendly."

More Cloudflare cons

"The process to upgrade from one version to another can be a lot simpler than it is currently."

"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."

"There's always room for improvement. Occasionally, there might be false-positive alerts."

"Sometimes, support tickets don't get addressed quickly."

"There is nothing specific where the application firewall is falling short."

"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."

"If they can bring in generative AI features, that would be useful."

"The only disadvantage of Imperva is that it is a pretty costly solution."

More Imperva Web Application Firewall cons

"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"We are using the free version."

"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."

"A free version of the solution is available."

"I give the price a five out of ten."

"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."

"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."

More Cloudflare pricing and cost advice

"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."

"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."

"The cost of this solution depends on the platform."

"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."

"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."

"The solution's pricing is an issue."

"Imperva Web Application Firewall is expensive."

"Imperva Web Application Firewall's pricing is expensive."

Reviews from real users

“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. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“The most valuable feature of Cloudflare is the GUI. You are able to control the solution very
well through the interface. There is a lot of functionality that is embedded in the service.” PeerSpot user, Competence Center Manager at a tech services company
