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.

Quotes from Members

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

Pros

"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"Technical support has a very fast response time and they are helpful."
"Cloudflare is cheaper compared to Azure WAF, which I have considered before."
"The product has a valuable security control functionality."
"The initial setup process is simple."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"The ability to configure multiple policies for different requirements is a strong feature of Fortinet FortiWeb."
"Technical support is very good. they are quite helpful and responsive."
"L-7 protection makes possible to protect legacy/not up-to-date servers/applications without changing the application code."
"Fortinet FortiWeb uses smaller boxes while meeting the same technical specifications, which automatically makes it cheaper than F5."
"We can block access using the IP address so no one can connect to our web server or website using the real IP."
"Auto Learn feature: Makes policy additions or deletions for my customers very simple​"
"The policies and the filtering are the most valuable features, especially traffic, URL, and application filtering. The solution is excellent at detecting vulnerabilities."
"My experience with the solution has been very positive."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"The reporting could be improved if it were more granular."
"The learning curve was steep initially."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"Their documentation could be better. They don't have documentation that explains everything well."
"The solution's learning curve can still be further reduced"
"We have noticed some latency when the call goes through the firewall. That could be improved."
"The ModSecurity core rules need to be updated."
"Fortinet FortiWeb could improve data integration."
"The product can be costly."
"The downside to FortiWeb is it had issues integrating with HSM. They fixed the issue, however, it took a long time to fix and it wasn't pleasant."
"The upgrade process could be a bit smoother."
"The product is complicated to set up."
"FortiWeb Web Application Firewall needs to improve its performance."
"The price is a little higher than the competitors."
"Capacity-wise, since there is hardware involved, it cannot scale too much."
"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."
 

Pricing and Cost Advice

"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."
"It is not too pricey."
"The annual licensing fee is $10,000 USD."
"It starts at $20 and can easily go up to $200 monthly"
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"The solution is expensive."
"We pay $210 per month for CloudFlare WAF."
"FortiWeb has a good presence because of its price."
"Due to the situation in Iran with the sanctions, the price of this solution is very expensive."
"The product provides very good prices to customers. The price is set well and offers great value for money."
"There are no licensing costs."
"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."
"Keep a loose margin between your actual bandwidth and the product sizing when using hardware appliances. Only virtual machines are upgradable to larger sizes."
"The pricing is pretty good. We do pass a lot of traffic through our API servers. Something like 100 gigs of web traffic is a fair amount for reduced JSON API calls, but the cost is $50. For that peace of mind, we have thousands and thousands of customers that are protected by that $50, so it's a no-brainer."
"The tool is really expensive."
