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.

Comprehensive web protection has secured public apps and supports advanced audit requirements
Fortinet FortiWeb Cloud WAF-as-a-Service has multiple valuable aspects. The WAF solution secures whatever public domains have been published by the public platform or internal servers exposed to public users. Firewalls have limitations, which is why I suggest using a WAF solution. The firewall provides the same features but in a limited edition. When discussing the SaaS platform or Layer 7 layer of security, you will receive multiple benefits. Firewalls have limitations with signatures, bot protection, and DOS protection. Fortinet FortiWeb Cloud WAF-as-a-Service is a dedicated WAF product that handles all DOS protection, bot protection, API security, endpoint connectivity, signature-based support, and top 10 OWASP support. Multiple features are available. AI and ML-based technology is available in almost every tool today. When discussing troubleshooting, there are AI models that will solve your problem and provide information. AI is helpful because it will give you proper information regarding errors and troubleshooting.

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

"It protects web applications efficiently."
"The setup process is very simple for me."
"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."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"It is a SaaS solution unlike much of the competition."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"The technical support is really good."
"The initial setup is pretty easy, and it is easier than for the on-premises solution."
"The company provides technical support, and they are mostly available 24/7."
"Fortinet FortiWeb Cloud WAF-as-a-Service is a dedicated WAF product that handles all DOS protection, bot protection, API security, endpoint connectivity, signature-based support, and top 10 OWASP support."
"Regular updates are one of the aspects I appreciate about Fortinet FortiWeb Cloud WAF-as-a-Service, and it is provided by a leading brand in cybersecurity."
"I utilize Fortinet FortiWeb Cloud WAF-as-a-Service's AI-driven analytics, which is in the sixth generation of AI, and this is helping us protect against AI-based attacks, API-based attacks, and bot attacks."
"It is a secure tool."
"It is user-friendly and easy to work with."
"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."
"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."
"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."
"With active threat detection, we are no longer over-swamped with tons of useless events."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The blocked logs are difficult to read at times."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"Their documentation could be better. They don't have documentation that explains everything well."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The product can improve by having more multitenancy capability, which is currently not available."
"WAF doesn't directly affect bandwidth costs. It saves costs on protection. However, with the correct setup, it's difficult to determine if it saves costs overall due to the fixed enterprise plan fee."
"The usability of the interface could be improved as it is not user-friendly."
"While we find the solution to be really good overall, some improvements could be made to the alerting system, specifically around the health checks of endpoints."
"Fortinet FortiWeb Cloud WAF-as-a-Service could be improved with better logging capabilities, as many come with less spacing, necessitating a FortiSIM for enhanced functionality."
"I do not have any notes on improvement."
"The utilization of AI in Fortinet FortiWeb Cloud WAF-as-a-Service still needs to be upgraded and improved."
"The only thing I encountered was related to integration, mostly concerning translation."
"To measure the success of Fortinet FortiWeb Cloud WAF-as-a-Service's services and reporting capability, there is one drawback."
"What I think could be improved in the future is the inclusion of runtime application self-protection, as RASP is currently not part of the program, but it would be beneficial if that could be added into the FortiAP-S Cloud product."
"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."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
"There were several stability issues during the first pilot."
"It needs more customization in PDF reports."
 

Pricing and Cost Advice

"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."
"It starts at $20 and can easily go up to $200 monthly"
"We pay $210 per month for CloudFlare WAF."
"It is not too pricey."
"The solution is expensive."
"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 solution's pricing option needs to be more transparent for enterprise clients."
