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.

Cloud WAF has protected critical web apps and APIs and delivers fast bot and DDoS defense
Regarding improvements for Barracuda WAF-as-a-Service, the UI and user experience can feel dated. While the interface is functional and centralized, some third-party reviews indicate that the UI can feel outdated, and enhancements are required to provide an executive look that can be aligned with modern and intuitive next-generation competitors. The licensing and cost structure perspective may need clear planning. Barracuda service is customizable but external references note that licensing and cost planning can become complex. Advanced analytics and executive reporting could be better. The platform provides visibility and compliance reporting but organizations looking for a very polished executive dashboard, deep attack visualization, or broader cloud-native security context may find it more focused on WAF operation. Barracuda WAF-as-a-Service is best suited for app and API protection and is not a full CNAPP platform. It is strong for application layer protection but is not positioned as a full CNAPP covering posture management. Modernizing the UI further, simplifying packaging and licensing clarity, enhancing the executive reporting and risk dashboard, and expanding broader cloud-native integration would be beneficial improvements.

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.

Cons

"The ModSecurity core rules need to be updated."
"The product can improve by having more multitenancy capability, which is currently not available."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"The platform's control features related to real-time authentication and response time need improvement."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"The rate limiting functionality could be enhanced, as we find it somewhat limited."

"One area for improvement with Barracuda WAF-as-a-Service is the alert tuning because sometimes the system generates too many notifications for minor issues, which can overwhelm the team."

"It's a very specific solution that is only requested for a customer's web code or their global IT policy."

"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."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution is expensive."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"It starts at $20 and can easily go up to $200 monthly"
"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."
"We pay $210 per month for CloudFlare WAF."
"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."
"I rate the product's price a five on a scale of one to ten, where one is low, and ten is high. There are no additional costs to be paid apart from the standard licensing fees attached to the solution."
"The product is expensive but it offers flexible pricing. It could be affordable."
"It's very difficult for me to give an estimate of the cost. All I know is that we sell the box itself as a service."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
