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.

Consistently protect applications with advanced threat detection and active support
We have had a very good experience with Radware Cloud. It has significantly reduced attacks on our applications. All our critical applications are onboarded to Radware, which uses AI to automatically learn behavior patterns and refine security policies. It also provides comprehensive protection against the top ten web application security risks. Importantly, we have not experienced any zero-day attacks because Radware Cloud offers protection against emerging threats. The Emergency Response Team is very active, and I consistently receive excellent responses from them. It's a very comprehensive and user-friendly solution. It's easy to implement and integrate. We also have found it's easy to reach support if we need help. The solution has helped us enhance our cyber security posture. It's good for data protection. We've been able to protect our public-facing infrastructure. We haven't had any incidents or compromises in the entire three years we've used Radware. The Cloud WAF Service blocks unknown threats and attacks effectively. The analytics are very good. The API discovery feature is very helpful, and end-to-end API protection is useful. Everything is encrypted to ensure effective protection. We get Layer 7 protection from it. The API discovery is a very useful feature. It is easy to use. A few months before, I did a demo to learn more. We can see which APIs are being used or not. It helps us discover and remove unused APIs. In our case, we found 20 APIs that were not used by the team. We use the CDN features. It's pretty easy to use the combination of CDN and Cloud WAF. It helps your Radware Cloud connect with the nearest server or the Redware server. We have multiple servers worldwide, so this is useful for us. Integration is very easy. Sometimes, we have 10 to 15 applications hosted on the cloud. It's very easy to add applications. It's not complicated. From the Radware cloud, it's integrated with our SOC. All the logs are received by the SOC.

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."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The most valuable feature is its usability."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The most valuable feature is the web application firewall."
"The most valuable feature of Cloudflare DNS is security."
"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."
"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."
"The solution is scalable."
"The solution can scale."
"Imperva has a complete picture of how the applications are utilizing it. It is handy. DDoS is good. It has an internally managed database. It is very easy to integrate. We have integrated it with SIEM services."
"The solution integrates seamlessly with other tools and has a good alert mechanism."
"The solution can be configured in just a couple of minutes."
"It is easy to use and has good security."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"It mitigates all of the availabilities of risks around web applications."
"I highly recommend this product to others because I'm satisfied with the mitigation and proactive protection."
"Radware Bot Manager has been very useful. If any user tries to save a password on a mobile or a browser, it blocks that. We can see all the details about the traffic and port requests."
"The API Discovery is also very good because the application is outsourced, which means that we don't have the code. API Discovery allowed me to discover precisely how to orchestrate the API so that I could see the results."
"Radware Cloud WAF Service has several valuable features, with good support and a user-friendly GUI."
"One of the most valuable features we have found in the solution is protection against attacks from botnet networks and the requests that these remote networks can generate that are blocked from our servers. That frees us from having to deal with that traffic."
"DDoS protection is a valuable feature that works efficiently."
"The solution offers good protection."
"With the Radware Cloud WAF Service, we have not faced any incidents in six years."
 

Cons

"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."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"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."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"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 pricing could be improved."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"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."
"It should be more user-friendly. Like other web solutions, it would be helpful to be able to easily do policy configuration and identification inside the application. Understanding the in-depth configuration of a policy is somewhat difficult for an engineer, and they can improve that."
"There is nothing specific where the application firewall is falling short."
"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."
"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"The only disadvantage of Imperva is that it is a pretty costly solution."
"The UI interface needs improvement."
"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."
"Radware needs to improve the certificate renewal process for customers who want to be secured with HTTPS."
"We receive many reports from our security team of IPs flagged by our security tools, such as Palo Alto. I cannot add the file containing the IPs to get them blocked; instead, I have to contact Radware support and open a ticket for them to do it. I need to be able to block flagged IPs myself, as it currently takes more time to open a ticket, contact the support team, and wait four to six hours for a response. I want to be able to upload a file with 2,000-3,000 IPs in the console and then apply and save the configuration."
"The initial setup was complex and took a long time to complete."
"Sometimes, I encounter issues with password reset, particularly in the last two weeks. This indicates some reliability issues or problems within the management interface."
"We've had some issues with putting certificates in."
"Radware Cloud WAF Service has limited integrations, and I would like to see it integrate with our use of Azure DevOps."
"Radware does not have much online training available to help customers get the most out of this solution."
"Our only complaint is the reporting on the DDoS side. We also use Radware for on-premises DDoS protection and their Vision product. I just want to give paint you an example. We face so many Layer 3 and Layer 4 DDoS attacks on Cloud WAF. The reporting on those types of attacks can be improved."
 

Pricing and Cost Advice

"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The product's pricing is cheap."
"A free version of the solution is available."
"We are using the free version."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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 pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"The price of this solution is a little bit high compared to competitors."
"There is a license for this solution and we purchase the license annually with no additional fees."
"Imperva Web Application Firewall is expensive."
"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."
"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."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"Everybody complains about the price of this solution."
"Radware Cloud WAF Service falls within a mid-range price bracket compared to other web application firewall solutions."
"We are based in El Salvador and don't have a direct license with Radware; we purchase the license through resellers. The pricing is reasonable, as I managed an Akamai product in a previous position, and Cloud WAF is competitively priced."
"When compared to Akamai and F5, Radware's pricing and licensing are highly competitive."
"The price is a bulk average."
"We are paying $20,000 annually for six licenses that provide basic WAF functionality."
"I believe the prices are fair."
"The pricing is fair."
"We evaluated other options and, if I remember correctly, one of them was Fortinet, but they didn't seem as effective as Radware. But the price was the biggest difference. Radware had the best price for our type of network and level of scaling."
