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.

Security threats have been reduced through seamless deployment and strong integration with other tools
I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

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

Pros

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"It protects web applications efficiently."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"In general, it's a very good product: the solution is very stable, the performance is great, the product offers very good scalability, the pricing is very reasonable, the installation is very straightforward and quite simple, and technical support has a very fast response time and is helpful."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"If your goal is security, FortiWeb is your best choice."
"Fortinet FortiWeb has improved my organization by protecting our customer's web infrastructure environment."
"Fortinet offers simple, easy-to-use solutions."
"Both the internal firewall management and the cloud can be managed by a single console."
"FortiNet shows me the health of the entire network."
"One of the big advantages of using Fortinet FortiWeb is all the Fortinet family solutions use the same user interface and logic, which makes it easy to use, configure, manage, and understand if you have used one of their solutions before or are wanting to implement other Fortinet solutions in the future, and additionally, all Fortinet solutions can be managed with one application called FortiManager."
"We have had a lot of web application attacks and this product has protected us, as once it was implemented most of our problems were solved, including a DDoS attack against the seventh layer that it successfully protected us from."
"The features of FortiWeb Web Application Firewall (WAF) that have proven most effective in protecting web applications include web filtering, DDoS protection, geo-location blocking, and blocking SQL injection attacks."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
 

Cons

"Cloudflare Web Application Firewall should include port forwarding features."
"Cloudflare should update the version of the ModSecurity core rule set that they run on."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"The learning curve was steep initially."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The platform's control features related to real-time authentication and response time need improvement."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"I would like to see support for throughput up to 10 gbps and WAN support."
"Their documentation is fairly complete, but it's sometimes a little bit difficult to search for exactly what you're looking for to resolve an issue. There have been times when we've gone to try to search for areas that we needed to get information on, and it has not always been extremely clear exactly how a particular thing needs to be set up."
"Fortinet's customer support needs improvement. The expertise of engineers varies across different time zones, affecting the effectiveness of the support provided, especially during our daytime."
"Though the reporting is a nice aspect associated with the tool, I feel that it has certain shortcomings and can be made better."
"The initial setup process could be improved."
"Maybe the load balancing options could be enhanced."
"FortiWeb could have an inbound load balancing pack."
"FortiWeb Web Application Firewall (WAF) needs to update its attack prevention database."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"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."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"It starts at $20 and can easily go up to $200 monthly"
"It is not too pricey."
"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 licensing cost of the product is pretty high compared to other OEMs in the market."
"It is an expensive suite and it is an expensive solution, but it is a manageable one for an enterprise."
"I would rate the pricing a four out of ten."
"There's only one payment for the duration of the license. On a scale from one to five, I would rate pricing at four. I have not encountered any additional costs on my projects involving Fortinet FortiWeb."
"The maintenance fee for this product could be improved."
"FortiWeb can be purchased in VM mode for a lower price and the same features."
"The price is competitive."
"It should be somewhere about 36,000 Euros. That's the cost for three years. It's moderately priced."
