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.

Has provided strong protection against evolving threats but still needs support for configuration fine-tuning
The standout features of Akamai App and API Protector are rooted in it being the Web Application Firewall, where all traffic gets scanned, including the implementation of web firewall rules, and after this phase, traffic proceeds through the BMP, which is Bot Management. Akamai App and API Protector exceeds expectations in terms of AI capabilities, and it genuinely combines a plethora of advanced features. The area in which Akamai excels compared to other competitors with a WAF is in threat intelligence, as threats continually evolve, requiring ongoing updates to backend algorithms to effectively capture smart bots, and Akamai's commitment in that regard is backed by an excellent team, while other providers are still catching up.

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

"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"The security features are valuable. The particular feature we use is called OWASP."
"Technical support has a very fast response time and they are helpful."
"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."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"It is configurable via API."
"It protects web applications efficiently."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"The solution can scale extremely well."
"The most valuable feature is the DDoS protection, which is the main reason we got it."
"Site Defender service helps prepare, respond, and optimize against modern-day web attacks."
"The product is user-friendly."
"Traffic filtering and WAF are valuable."
"The product has a good UI."
"If you compare it to other products in the market, it's quite holistic in terms of the features that it provides."
"All the solution's features are very good."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"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."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"The learning curve was steep initially."
"The blocked logs are difficult to read at times."
"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The product can improve by having more multitenancy capability, which is currently not available."
"Their documentation could be better. They don't have documentation that explains everything well. They have documentation for everything you're looking for, but they lack a single piece of documentation to tie everything together. As a new user or beginner, it took us a little bit of time to figure out how to put all these things in place."
"Its stability could be better."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"Akamai needs to focus on quickly responding to risks, even those that may potentially be of zero threat..Maybe some of the documentation is a little confusing. They have a lot of different places where you can go to get information, and some of the information is quite out of date."
"They should allow for multiple security configurations in one account which will enhance the scalability."
"There are some issues with pushing configurations across a network. It still takes about 20 minutes and that means to retract it's another 20 minutes."
"In terms of precedence of Akamai rules, the last one is implemented. That is the one that is operational. If two rules contradict, the last one is implemented. We had a clash, but it was really tough to find that out. I would like to have a rulebook because, in their architecture documentation, it is not mentioned anywhere that if two rules clash, the last one works, and if it does not work, then what to do. This is something we were debating today with their tech support. With AWS, we get documents for the issues so that they do not occur in the future. Akamai's support and knowledge base needs to be improved."
"It could have better analytics and reporting visibility in the OEM console."
"They are already very flexible, but room for improvement is there. Reports generation could be better and should be improved."
"The product should provide a secure NTP."
"The solution could offer even more integrations."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"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."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
 

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 annual licensing fee is $10,000 USD."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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 pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"The solution is expensive."
"The product’s price is high."
"Cost depends on the volume of traffic."
"The product is expensive, but it is worth the money."
"The solution is expensive."
"The price they are offering is quite reasonable for premium customers, but it's very expensive if you're a small and medium-sized enterprises."
"One reason not all people use Akamai is that it is a little bit more expensive than some other providers."
"Akamai Web Application Protector is an expensive product."
"It's more expensive than others, but the ROI is good for large-scale infrastructure."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
