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

"It protects web applications efficiently."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"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."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"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."
"FortiGate is a stable product."
"Even though most products have the same functionality nowadays, FortiWeb is easy to integrate."
"One main feature we are very happy about is file security and upload functionality."
"If your goal is security, FortiWeb is your best choice."
"The platform's stability is good."
"Price and licensing is fine; it is one of the cheapest solutions and does its job."
"FortiWeb Web Application Firewall helps us to block certain categories of browsing, such as weapons, and other inappropriate content on the client side. We have also blocked social media sites like TikTok and Facebook to enhance user productivity and maintain application security."
"The product is easy to configure."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The platform's control features related to real-time authentication and response time need improvement."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"In my experience, Fortinet FortiWeb could improve the intelligent features to acknowledge whether any threat or incident that's running happened. Then give us the ability to escalate it to layer 2 or layer 3 in the network operations."
"We want to see more detailed logging, such as audit logging, as this would significantly enhance the solution's reporting. We currently get some information from logs, but more would be better."
"The false positives are also annoying."
"It would also be helpful if they could introduce easier reporting. It's good to have those reports that go to C-level management, and Fortinet does provide some graphs, but if they went into some more detail, that would be great."
"The initial setup is complex and takes between three to six months."
"There could be ADC offering as well."
"Fortinet WAF came out recently, and there is not much feedback about customer experience. For each project, customers ask about the scenarios and references of the customers who have implemented this solution, which we don't have. They need to simplify the customer experience and provide more information so that we can propose Fortinet Fortiweb as a WAF solution to customers and convince them. They need to improve their service and training. We need good training to implement and use it properly and know more about it. We still don't know much about Fortinet WAF. We didn't get any proper training sessions. Other vendors like Cisco, Palo Alto, Check Point, and Barracuda provide such sessions. Whenever we receive a request from a customer for this solution, we just give the price. We don't propose this solution because we don't know much about it. We propose whatever we are familiar with and what is supported."
"I would like to see more improvements with respect to threat intelligence."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"It is not too pricey."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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"
"The annual licensing fee is $10,000 USD."
"The solution's pricing option needs to be more transparent for enterprise clients."
"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."
"If one is cheap and ten is expensive, I rate the tool an eight."
"The product provides very good prices to customers. The price is set well and offers great value for money."
"So far, I have been pretty pleased with the way it's priced and licensed. The way it's done makes it easy, especially for an organization like us, so I've been pleased with the way it's priced and licensed right now."
"Previously, for each project, the cost was $800 to $1,000 per application. Now, it's $100 to $120. For some of the applications, there is a 90% reduction, and for some of the applications, there is a 50% reduction. We're paying only $500 to $600."
"The price is competitive."
"This product offers two pricing options: a standard package and an advanced package."
"The costs are standard. We pay around $1,600 yearly."
"It is an expensive suite and it is an expensive solution, but it is a manageable one for an enterprise."
