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.

Optimizing global application performance with robust security measures and advanced traffic management

DDoS capabilities in Azure Front Door could certainly be improved. Although Microsoft states it comes with basic DDoS protections out of the box, I find it often ineffectual in mitigating thousands of requests from a single source in a short span of time. User then have to rely on the WAF module where users must configure rate-limiting rules, as it does not automatically sense malicious spikes in traffic. I believe Front Door should have an out-of-the-box premium DDoS protection that can automatically detect and block malicious traffic. I would appreciate improvements in the turnaround time for support, especially since issues with Azure Front Door are usually critical for businesses. If there is an issue, it often results in downtime for line of business applications. I have faced this situation multiple times as one of the largest financial institutions in India is hosted there, adhering to strict SLAs that require prompt responses.

Room for improvement with user interface while competitive pricing impresses

It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

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 rate limiting features and customizations in terms of URL match and applying policies are valuable to me."

"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."

"Caching is the most valuable feature of Cloudflare Web Application Firewall."

"This is a good product; it's reliable and scales well."

"The initial setup process is simple."

"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."

"It protects web applications efficiently."

More Cloudflare Web Application Firewall pros

"I find the technical support excellent, and I rate it a ten."

"The tool is easy to use for beginners."

"Has a great application firewall and we like the security."

"I particularly appreciate its load-balancing capabilities as it allows us to manage multiple instances and support a global presence effectively."

"The price is one of the most important aspects of the product; it's quite affordable, and the ease of the implementation is really vital because it's very easy to implement for our customers as we simply handle the first phase and Microsoft does all the rest."

"The solution is good."

"The price is one of the most important aspects of the product. It's quite affordable."

"You can assign as many web application firewall policies as you want to the same instance of Front Door."

More Azure Front Door pros

"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."

"The product's most valuable feature is its ability to set up the rules easily."

"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."

"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."

"The product can improve by having more multitenancy capability, which is currently not available."

"Cloudflare should update the version of the ModSecurity core rule set that they run on."

"Their documentation could be better. They don't have documentation that explains everything well."

"Its stability could be better."

"If they add logs history within the Cloudflare offering, that would be a great benefit."

"The dashboard could be more user-friendly."

More Cloudflare Web Application Firewall cons

"We should be able to use Front Door defenders with multiple cloud vendors. Currently, they can be used only with the Azure cloud. Azure Front Door should also be able to do global load balancing and provide internal front door services. Microsoft should clearly define what Traffic Manager, Application Gateway, and Azure Front Door products do. These are similar products, and people get confused between these products."

"The user interface needs improvement as it is difficult to create the mapping to link the problem with your private address sources."

"The tool should improve its cost."

"There's a limitation on the amount of global rules we can add."

"We should be able to use Front Door defenders with multiple cloud vendors. Currently, they can be used only with the Azure cloud."

"My suggestion for improvement would be to enhance the Data Export feature to include specific tables, particularly the Azure Diagnostics table."

"There is room for improvement and they're working on it."

"There could be improvements regarding its pricing for large-scale projects."

More Azure Front Door cons

"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."

"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."

"The UI is not very intuitive and could be better."

"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."

Pricing and Cost Advice

"The solution's pricing option needs to be more transparent for enterprise clients."

"The annual licensing fee is $10,000 USD."

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."

"Cloudflare Web Application Firewall is more affordable than other solutions."

"We pay $210 per month for CloudFlare WAF."

"The solution is expensive."

"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."

More Cloudflare Web Application Firewall pricing and cost advice

"Considering the standard licensing of the tool, even though we have not checked the billing as of now, it might not be very costly."

"The solution is a bit expensive."

"The product is expensive."

"The transition to the premium tier has led to increased costs, making it more expensive than the classic tier."

"The pricing of the solution is good."

"It is on a pay-as-you-go basis."

"The product has an affordable cost."

"The pricing is 50% less than Akamai."

"Signal Sciences is pretty cheap compared to other solutions."
