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.

For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.

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

"The setup process is very simple for me."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"This is a good product; it's reliable and scales well."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"The product has improved our security posture by blocking bad actors."
"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."
"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."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"The initial setup was very straightforward. Deployment took about ten minutes or less."
"It is a one-click WAF with no effort needed."
"The simple configuration and the scalability have been most valuable. We are able to scale across all of our different AWS instances."
"The features I find most useful in AWS WAF are that we can integrate and write custom regex rules where we can specify URLs or links that cannot be accessed by certain countries or specific IPs."
"The most valuable features of AWS WAF are its cloud-native and on-demand."
"The price of the product is fair enough and one of the product's advantages."
"I like the scalability, as it provides platform, infrastructure and software as a service."
"One of the most valuable features of AWS WAF is its ability to filter web app traffic, allowing us to specify conditions such as IP addresses and HTTP headers."
"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 rate limiting functionality could be enhanced, as we find it somewhat limited."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"Its stability could be better."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The dashboard could be more user-friendly."
"The price could be improved."
"Whenever there is an issue, it is just not that simple to resolve, especially if you don't have premium support."
"On the UI side, I would like it if they could bring back the conditions view which had geo match, IP sets and etc."
"The product must provide more features."
"The solution is cloud-based, and therefore the billing model that comes with it could be more intuitive, in my opinion. It's very easy to not fully understand how you tag things for billing and then you can quite easily run up a high bill without realizing it. The solution needs to be more intuitive around the tagging system, which enables the billing. Right now, I have a cloud architect that does that on our behalf and it isn't something that a business user could use because it still requires quite a lot of technical knowledge to do effectively."
"The solution could be more reliable."
"They should work to define more threats, add more security, and make it more compliant with more security companies."
"The serverless product from AWS WAF could be improved. For example, they have only one serverless series, Lambda, but they should extend and improve it. Additionally, the firewall rules are not very easy to configure."
"The area that should be improved is licensing."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"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."
"It starts at $20 and can easily go up to $200 monthly"
"The annual licensing fee is $10,000 USD."
"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 is expensive."
"There are different scale options available for WAF."
"The solution's cost depends on the use cases."
"It's an annual subscription."
"It's quite affordable. It's in the middle."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"The pricing is good and manageable."
"The product is moderately priced."
"Its price is fair. There is a very fair amount that they charge. It has a pay-as-you-go model, so it pretty much depends on how much a user uses it. As per the cloud norms, the more you use, the more you pay. I would rate it a five out of ten in terms of pricing."
