It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

AWS's cloud-native security simplifies rule enforcement but needs better DDoS integration
The dashboarding could be improved, and the default metrics provided by AWS WAF could be upgraded. The rate at which AWS updates their managed rule sets could be better. Features like bot protection or DDoS mitigation, available with other WAF vendors, do not come natively with AWS WAF. Instead, they are part of AWS Shield. Providing DDoS protection as part of their WAF solution would be beneficial.

A good solution to implement web application firewall for applications
There are some lags in Signal Sciences for the web application firewalls. Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic. There is a little bit of complexity with custom rules that should be removed. Signal Sciences should add a feature called rate limiting with multiple options, wherein I can create a rate limiting based on the cookie request or the IP.

Quotes from Members

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

Pros

"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The solution is very good at mitigating threats."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"The most valuable feature is the way it blocks threats to external applications."
"The most valuable feature is that it is very easy to configure. It just takes a couple of minutes."
"The ability to take multiple data sets and match those data sets together is the solution's most valuable feature. The data lake that comes with it is very useful because that allows us to match data sets with different configurations that we wouldn't normally be able to match."
"The cloud-native nature of AWS is crucial since most of our workload is in AWS, making AWS WAF native to Amazon Web Services."
"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 availability, ease of configuration, and documentation are valuable."
"The cloud-native nature of AWS is crucial since most of our workload is in AWS, making AWS WAF native to Amazon Web Services."
"AWS has flexibility in terms of WAF rules."
"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."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
 

Cons

"The solution could work at being less expensive. It costs a lot to use it."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The pricing could be improved."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The product support needs to be accessible from more places, a wider area of coverage."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"The solution could be more user-friendly."
"We should be able to do proper whitelisting."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"The default content policy available in the tool is not very strong compared to the competitors."
"AWS WAF should provide better protection to its users, and the security features need to improve."
"We haven't faced any problems with the solution."
"Compatibility and integration functionalities, especially with services like Kafka for event-driven messaging, could be better."
"I would like to see it more tightly integrated with other AWS services."
"We have issues with reporting, troubleshooting, and analytics. AWS WAF needs to bring costs down."
"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."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
 

Pricing and Cost Advice

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The product's pricing is minimal compared to other products."
"A free version of the solution is available."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We don't have any issues with the price."
"The price of the solution is expensive."
"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."
"It has a variable pricing scheme."
"The price of AWS WAF is reasonable, it is not expensive and it is not cheap."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven or eight out of ten."
"You need an additional AWS subscription for this product if you are buying a managed tool."
"We are kind of doing a POC comparison to see what works best. Pricing-wise, AWS is one of the most attractive ones. It is fairly cheap, and we like the pricing part. We're trying to see what makes more sense operation-wise, license-wise, and pricing-wise."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"For Kubernetes microservices, AWS is more expensive compared to OCI. AWS costs approximately 70 cents per hour, while OCI is 50% cheaper."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
