Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Has significantly improved threat visibility and reduced false positives through intelligent bot detection and real-time analysis
The best features of Radware Cloud WAF Service that I prefer most include the bot protection. Its deployment was very smooth and flexible when I started deploying it. The reporting and visibility feature of the Bot Manager are noteworthy, as the dashboard gives clear insight into the traffic, activity, and block threats. The AI threat intelligence feature is quite impressive. In terms of blocking unknown threats and attacks, I assess Radware Cloud WAF Service as quite impressive; if I have to rate it out of 10, I would rate it eight and a half. The automated analytics for looking at events with Radware Cloud WAF Service is generally fine, and whenever we use it, it gives almost perfect results. In API protection with Radware Cloud WAF Service, we have multiple applications that we are using currently, and whenever there is any threat related to an API, it helps us provide detailed insight. Additionally, whenever there is unusual API traffic, it helps us monitor and detect threats.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Quotes from Members

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

Pros

"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"The security features are valuable. The particular feature we use is called OWASP."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"We feel safe using Radware, and we are happy with it."
"The real-time BLA detection and mitigation processes have significantly enhanced our threat management with Radware Cloud WAF Service."
"Radware Cloud WAF Service is very top-notch and we in the banking institution are happy with it."
"The solution offers good protection."
"I particularly appreciate the low administrative burden of this solution, as well as the excellent monitoring tools."
"Radware Cloud WAF Service blocks threats effectively, providing a comprehensive report that shows the traffic and denied traffic from malicious IPs or specific countries, so I am satisfied."
"Radware Cloud WAF Service is really good for protecting against zero-day attacks as it protects our organization and businesses effectively."
"Radware Cloud WAF Service has several valuable features, with good support and a user-friendly GUI."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"If they add logs history within the Cloudflare offering, that would be a great benefit."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The reporting could be improved if it were more granular."
"The learning curve was steep initially."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."
"The product can improve by having more multitenancy capability, which is currently not available."
"The platform's control features related to real-time authentication and response time need improvement."
"The initial setup was complex and took a long time to complete."
"The area that can improve with Radware Cloud WAF Service is the speed at which they block geo-fencing and IP for P1 cases, which currently takes about an hour. If they could reduce that to ten to 15 minutes, it would be easier for us."
"My experience with Radware Cloud WAF Service's customer support could be better."
"In some cases, if the configuration of rules is too strict or complex, there might be a possibility that genuine traffic gets blocked or considered a false positive."
"The primary area for improvement is in issue detection and understanding whether a log is a false positive. It can sometimes be a challenge to take the data of a given security event and determine if it's a genuine threat using a Wiki etc."
"We received a notification where Radware Cloud WAF Service stopped working properly in our cloud environment without any prior notification."
"To make Radware Cloud WAF Service even more useful for my organization, I believe there should be greater integration with other tools, such as log tools."
"The pricing means it prices itself out of a lot of people's budgets, which is a significant concern."
"The UI is not very intuitive and could be better."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
 

Pricing and Cost Advice

"It is not too pricey."
"The solution is expensive."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"It starts at $20 and can easily go up to $200 monthly"
"The solution's pricing option needs to be more transparent for enterprise clients."
"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."
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"The price is a bulk average."
"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."
"I am not directly involved in pricing and setup cost discussions, but it seems that Radware offers a more cost-effective solution compared to F5. It is considered a good value for our budget."
"If you plan to deploy Cloud WAF, keep in mind that the product is priced based on the megabits of traffic that pass through and the number of transactions. You should get your requirements correct up front. The active attackers feed and CDN services cost extra, so you need to negotiate these features upfront."
"The pricing is fair. We compared Radware to others using industry reviews and Radware is at the top right now."
"The pricing is fair; it's neither particularly cheap nor expensive."
"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."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
