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.

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.

Improved mobile app development and user experience through optimization and security
The most valuable aspects include the optimization of application performance by optimizing API calls for a smoother user experience and faster load times. Furthermore, I restructured our code base to establish a more efficient development workflow. During my tenure, I integrated various security features for mobile applications, such as JWT tokens for secure authentication and data encryption using AES algorithms. I also focused on secure storage options, secure coding practices, and platform-specific security compliance, like Android's SafeNet and iOS Secure Enclave.

Quotes from Members

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

Pros

"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"The security features are valuable. The particular feature we use is called OWASP."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"It protects web applications efficiently."
"The initial setup process is simple."
"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."
"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 product's most valuable feature is its ability to set up the rules easily."
"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."
"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."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"The tool's most valuable feature is the Uplynk platform for streaming purposes."
"I recommend this solution because, for me, it's one of the most efficient and performant CDN operators."
"It's super easy to use and integrate with."
"The product is easy to use and easy to implement."
"The Rules Engine V4 is the most valuable feature."
"Without EdgeCast, our website was taking 10 to 15 seconds to load; with EdgeCast, it loads under five seconds and it's a good product."
"The customer support and service responsiveness were excellent."
 

Cons

"Their documentation could be better. They don't have documentation that explains everything well."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"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."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"Its stability could be better."
"The product can improve by having more multitenancy capability, which is currently not available."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The reporting could be more granular."
"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."
"The tool needs to resolve its lack of innovation."
"The comparable features that we are looking at fits into Cloudflare's free version, as opposed to Verizon EdgeCast, which we are paying for."
"The web interface of the Verizon Edgecast portal is very old. It's not user-friendly, slow, and it is missing some valuable features like the ability to make bulk changes."
"We could not create more than 15 custom rules."
"The web interface of the Verizon Edgecast portal is very old; it's not user-friendly, slow, and it is missing some valuable features like the ability to make bulk changes."
"In the next release, I would like to see more global endpoints for their CDN and a lower price."
 

Pricing and Cost Advice

"The solution is expensive."
"The solution's pricing option needs to be more transparent for enterprise clients."
"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."
"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 pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"We pay $210 per month for CloudFlare WAF."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
"When I modeled it out, we are spending somewhere between $600 to $800 a month with Verizon EdgeCast."
"Be careful about the options because to have all the features can be very expensive."
"The product is cheaper compared to other solutions."
