Spencer Malmad - PeerSpot reviewer
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 a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.
Abdullah Jin - PeerSpot reviewer
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

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"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."
"I rate its stability a ten out of ten."
"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."
"Centralized, full-featured DNS."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Does a good job preventing web application attacks."
"There is a huge signature repository"
"The product has a valuable security control functionality."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"It protects web applications efficiently."
"The product has improved our security posture by blocking bad actors."
"It is a SaaS solution unlike much of the competition."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"The solution can be configured in just a couple of minutes."
"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"I am impressed with the product's scalability, availability, easy management, and security. We were able to integrate the product with Azure and Sentinel."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"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."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"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 mitigates all of the availabilities of risks around web applications."
 

Cons

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"Cloudflare's console should be made more user-friendly."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"Integration involving API with other products could be more user-friendly."
"The product support needs to be accessible from more places, a wider area of coverage."
"Technical support is lacking."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"They have some limitations with third-party integrations."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The reporting could be more granular."
"The ModSecurity core rules need to be updated."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"The only disadvantage of Imperva is that it is a pretty costly solution."
"Imperva Web Application Firewall is very expensive."
"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"It's a complicated tool to keep."
"The signature updates could be faster. Sometimes we have to upload signatures to the Imperva portal for checking and analysis before we can use them."
"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."
"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

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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 cost primarily depends on the size of the organization."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"There are no additional costs beyond the standard licensing fees."
"The price is reasonable."
"We are using the free tier of the solution."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The annual licensing fee is $10,000 USD."
"The solution's pricing option needs to be more transparent for enterprise clients."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"We pay $210 per month for CloudFlare WAF."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"It is not too pricey."
"The solution is expensive."
"Imperva Web Application Firewall is expensive."
"There is a license for this solution and we purchase the license annually with no additional fees."
"The price of this solution is a little bit high compared to competitors."
"The solution's pricing is an issue."
"The cost of this solution depends on the platform."
"There are a couple of different licensing models."
"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’s pricing is a bit higher in the market since it offers a full-blown WAF."
