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 While the interface is functional and centralized, some third-party reviews indicate that the UI can feel outdated, and enhancements are required to provide an executive look that can be aligned with modern and intuitive next-generation competitors.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.

Helps us to monitor attacks to our sites and prevents a lot of them
Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

Quotes from Members

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

Pros

"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"It is configurable via API."
"It is a SaaS solution unlike much of the competition."
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"Cloudflare has positively impacted my organization by making it easier for me to handle and set up DNS for multiple clients; I can easily go in and access their accounts, make changes they need, and it's a one-stop shop."
"I like its ability to identify known attacks, including DDOS attacks. It's valuable because software must be able to stop known attacks. Application attacks are evolving all the time. When it comes to software-as-a-service, we need to have software that knows about all the latest attacks. It should also protect against major unknown attacks."
"It provides an ease of policy management."
"The product's bot protection feature is valuable for our company."
"Legitimate traffic has improved around 30 to 40% after implementing Barracuda WAF-as-a-Service."
"Barracuda WAF-as-a-Service has a positive impact in my organization by strengthening security, improving resilience, and reducing operational overhead."
"The solution covers a lot of major protection or threat management functions in the feature itself."
"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."
"The solution can be used for threat prevention or as a cloud-to-cloud backup system"
"With active threat detection, we are no longer over-swamped with tons of useless events."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
"Perimeter control and active vulnerability scanner are the most valuable features."
"They are the only solution that fits our success criteria and business objectives: WAF must have a low (<5%) false negative rate and be ready to protect from all well-known web attacks."
"Vulnerability scanner and WAF are valuable features."
"The most powerful feature is the ability to first learn what type of query to make to your web application when it is attacked and what type of query creates a false positive to your app."
 

Cons

"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"Support can be challenging at times."
"The ModSecurity core rules need to be updated."
"The reporting could be improved if it were more granular."
"Their documentation could be better. They don't have documentation that explains everything well."
"Its stability could be better."
"The dashboard could be more user-friendly."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"Some complex issues take longer to resolve, but overall, we have been satisfied with the support."
"We found it a bit slow when accessing it through the web browser."
"The stability of the product is an area of concern where improvements are required."
"The licensing and cost structure perspective may need clear planning."
"It's a very specific solution that is only requested for a customer's web code or their global IT policy."
"I chose an eight out of ten perhaps because the price is very high and not recommended for all organizations."
"One way Barracuda WAF-as-a-Service can be improved is by making the implementation easier."
"I think pricing could be improved regarding Barracuda WAF-as-a-Service."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"It needs more customization in PDF reports."
"There were several stability issues during the first pilot."
"Wallarm uses a learning mechanism to detect attacks and to avoid false positives. If Wallarm blocks some illegitimate request, then you can go to the management console and mark this request as false positive, but sometimes this does not work properly."
"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
 

Pricing and Cost Advice

"The solution's pricing option needs to be more transparent for enterprise clients."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"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"
"It is not too pricey."
"The solution is expensive."
"The annual licensing fee is $10,000 USD."
"The product is expensive but it offers flexible pricing. It could be affordable."
"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."
"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."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
