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

"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"Technical support has a very fast response time and they are helpful."
"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."
"Does a good job preventing web application attacks."
"It is a SaaS solution unlike much of the competition."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"The setup process is very simple for me."
"One common use case is using detection protection for enhancing security models in AWS. Another use case is implementing log analysis and response recovery procedures for email services."
"It's simple, easy to use."
"The initial setup was very straightforward. Deployment took about ten minutes or less."
"The most valuable feature of the solution is the ability to integrate central sets. It protects from intrusion attacks such as scripting and SQL injections."
"The most valuable feature of AWS WAF is its highly configurable rules system."
"AWS WAF is something that someone from a cloud background or cloud security background leverages. If they want to natively use a solution in the cloud, AWS WAF comes in handy. It's very useful for that, and the way we can fine-tune the WAF rules is also nice."
"The product's initial setup phase was very simple."
"The most valuable aspect is that it protects our code. It's a bit difficult to overwrite code in our application. It also protects against threats."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The learning curve was steep initially."
"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."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"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."
"The product can improve by having more multitenancy capability, which is currently not available."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"AWS WAF's signature sets have room for improvement due to false positives."
"The price could be improved."
"They should work to define more threats, add more security, and make it more compliant with more security companies."
"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."
"In a future release of this solution, I would like to see additional management features to make things simpler."
"For uniformity, AWS has a well-accepted framework. However, it'll be better for us if we could have some more documented guidelines on how the specific business should be structured and the roles that the cloud recommends."
"The pricing model is complicated."
"I believe there is a need to move towards real-time analysis with the help of AI and intelligent systems in the future. This would reduce the reliance on manual work and enhance the functionality of detection protection. By incorporating AI-driven data analysis and data science techniques, we can improve the solution's user-friendliness, security compatibility, and accuracy."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"It starts at $20 and can easily go up to $200 monthly"
"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 annual licensing fee is $10,000 USD."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The solution's pricing option needs to be more transparent for enterprise clients."
"It is not too pricey."
"The solution is expensive."
"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."
"AWS WAF is pay-as-you-go, I only pay for what I'm using. There is no subscription or any payment upfront, I can terminate use at any time. Which is an advantage."
"The price is average."
"AWS is not that costly by comparison. They are maybe close to $40 per month. I think it was between $29 or $39."
"AWS WAF costs $5 monthly plus $1 for the rule. It's cheap, cost-wise. It's worth the money."
"The price of AWS WAF is reasonable, it is not expensive and it is not cheap."
"It's quite affordable. It's in the middle."
"For our infrastructure, we probably pay around $16,000 per month for AWS WAF. Because alternative WAF solutions provide even more features, I think the AWS WAF is a bit pricey"
