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!

"Vulnerability scanner and WAF are valuable features."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The reporting could be more granular."
"Their documentation could be better. They don't have documentation that explains everything well."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The solution's learning curve can still be further reduced"
"Its stability could be better."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"The only thing I encountered was related to integration, mostly concerning translation."
"The usability of the interface could be improved as it is not user-friendly."
"The utilization of AI in Fortinet FortiWeb Cloud WAF-as-a-Service still needs to be upgraded and improved."

"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."

"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."
"It needs more customization in PDF reports."
"There were several stability issues during the first pilot."
 

Pricing and Cost Advice

"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."
"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."
"The solution's pricing option needs to be more transparent for enterprise clients."
"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"
