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.

Load balancing has simplified deployments and improves application performance monitoring
I don't think of features that will make Radware Alteon better because it is already better, but to be able to compete also with other competitors, the price is something to consider. It is not actually that expensive, but for their level, there are other load balancers with the same feature, but they have a lower price, so pricing is the only point I can give. In the future, I would like to see some other security features added, such as DDoS, which is Distributed Denial of Service. Currently, it has the Web Application Firewall feature, but in the future, they can also add a DDoS feature or a more in-depth DDoS feature.

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

"It is configurable via API."
"It is a SaaS solution unlike much of the competition."
"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"Technical support has a very fast response time and they are helpful."
"If someone wants an effective product with good capabilities, they should consider this solution."
"The integrated application protection provided by Alteon is very good. It really helps to avoid false positives in some cases. It provides important granularity to avoid a situation in which security or cybersecurity scenarios escape us."
"I am finding SSL-TLS acceleration the most valuable function, with certificate management."
"With Alteon, the load-balancing options are practically unlimited. We haven't had any issues with offloading, decryption, putting in cookies, or any other load-balancing features. We can check URLs, etc., on the back end for load balancing instead of running a TCP check. We're also doing some certificate stuff on there. Alteon covers all of the standard load-balancing techniques, and we employ most of them daily."
"Radware's application delivery controller (ADC) provides advanced and comprehensive application delivery capabilities, ensuring 24/7 availability."
"Overall, I would rate Alteon a nine out of ten."
"The simplicity of the GUI is what I like the most about Radware Alteon."
"The support from Radware is consistently excellent and always available."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"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."
"The product's most valuable feature is its ability to set up the rules easily."
"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."
 

Cons

"The platform's control features related to real-time authentication and response time need improvement."
"The reporting could be more granular."
"The dashboard could be more user-friendly."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The product can improve by having more multitenancy capability, which is currently not available."
"The solution's learning curve can still be further reduced"
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"The product can improve by having more multitenancy capability, which is currently not available."
"Integration with cloud services could be improved. Every now and then, we need engagement to address challenges with cloud integrations."
"We stopped using it because the application failed."
"To some extent, we are satisfied with the technical support but it can be better- it can be much better."
"Support is very important because if we get good support, we'll be able to sell and supply more numbers."
"The user interface can be improved."
"I would like to see the loading documentation improved."
"The GUI needs to be improved. Right now, the solution isn't so user-friendly."
"I would like for the load balancing to work with premier and the cloud, a mix of premium and cloud."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"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

"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."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The solution's pricing option needs to be more transparent for enterprise clients."
"It starts at $20 and can easily go up to $200 monthly"
"It is not too pricey."
"The annual licensing fee is $10,000 USD."
"We pay $210 per month for CloudFlare WAF."
"The price conforms to what the tool provides. It is not an inexpensive tool and not all companies can afford an ADC solution such as Alteon. However, it justifies its price with the options it offers."
"The pricing is better than the competition. It is getting more pricey as the years go on, as more people are migrating to it, and as the technology gets better."
"Our government agency opted for Radware Alteon due to its affordability and efficiency. While I can't say precisely how much it costs the organization, the price per device. In India, we always look for affordable products, so I assume Alteon is cost-effective because the government chose it."
"It is cost-efficient. That is why we have gone with Alteon. As a product, it is efficient and robust. We have not faced any issues with the device."
"It is the best in the industry. It was better than the competition, and that is what made us go ahead with them."
"The pricing seems reasonable to me for what the solution provides. It is within the parameters of this type of solution."
"I'm content with Alteon's pricing."
"It is not the priciest and it is not the cheapest. For our solution, it was right in the middle of price performance."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
