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

"The most valuable feature of Cloudflare DNS is security."
"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."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It is a fast and secure DNS."
"It is a fast and secure DNS."
"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."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The interface is good."
"The most valuable feature is that it is very easy to configure. It just takes a couple of minutes."
"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 most valuable features of AWS WAF are its cloud-native and on-demand."
"The solution is stable."
"What I like best about AWS WAF is that it's a simple tool, so I could understand the basics of AWS WAF in two to three hours."
"The customizable features are good."
"The ease of deployment of the product is valuable to me."
"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

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"Integration involving API with other products could be more user-friendly."
"The pricing could be improved."
"The solution could be more user-friendly."
"Latencies are always a problem."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"It will be helpful if the product recommends rules that we can implement."
"I find the documentation somewhat complex to implement during the initial stages."
"In a future release of this solution, I would like to see additional management features to make things simpler."
"The dashboarding could be improved, and the default metrics provided by AWS WAF could be upgraded."
"I would like to see it more tightly integrated with other AWS services."
"An improvement area would be that it's more of a manual effort when you have to enable rules. That's one of the downsides. If that can be done in an automated way, it would be great. That's a lagging feature currently."
"We must monitor and clean up the WAF manually."
"AWS WAF would be better if it uses AI or machine learning to detect a potential attack or a potential IP that creates an attack even before it happens. I want AWS WAF to capture the IP and automatically write the rule to automate the entire process."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"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."
 

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"I give the price a five out of ten."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The price is reasonable."
"We are using the free version."
"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 product's pricing is cheap."
"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."
"The product is moderately priced."
"It has a variable pricing scheme."
"AWS WAF costs $5 monthly plus $1 for the rule. It's cheap, cost-wise. It's worth the money."
"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"
"The product’s pricing is reasonable."
"The price of AWS WAF is reasonable, it is not expensive and it is not cheap."
"The solution is affordable."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
