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 solution automatically detects and responds to certain types of traffic based on geolocation."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"Generally, I am satisfied with this product."
"Cloudflare has many features."
"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."
"I rate its stability a ten out of ten."
"The UI is good."
"The most valuable features of the solution are performance and security."
"The automation of blocking for security attacks is valuable, with AWS applying rate limiting."
"The most valuable feature is the security, making sure that files are protected, preventing unauthorized users from accessing the system."
"AWS WAF is very easy to use and configure on AWS."
"We can host any DB or application on the solution."
"I believe the most impressive features are integration and ease of use. The best part of AWS WAF is the cloud-native WAF integration. There aren't any hidden deployments or hidden infrastructure which we have to maintain to have AWS WAF. AWS maintains everything; all we have to do is click the button, and WAF will be activated. Any packet coming through the internet will be filtered through."
"The agility is great for us in terms of cloud services in general."
"The tool’s stability is very good."
"The most valuable feature of the solution is the ability to integrate central sets. It protects from intrusion attacks such as scripting and SQL injections."
"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 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."
 

Cons

"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."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"The product needs to improve its automation."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"I find the documentation somewhat complex to implement during the initial stages."
"The solution should identify why it blocks particular websites."
"We need more support as we go global."
"The solution could be more reliable."
"In a future release of this solution, I would like to see additional management features to make things simpler."
"Rule exclusion could be a bit more transparent."
"It will be helpful if the product recommends rules that we can implement."
"The setup is complicated."
"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

"A free version of the solution is available."
"The product's pricing is minimal compared to other products."
"The price is reasonable."
"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."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"We are using the free tier of the solution."
"I would rate AWS WAF's pricing a seven out of ten."
"It has a variable pricing scheme."
"AWS WAF has reasonable pricing."
"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."
"AWS WAF has reasonable pricing."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"The price is average."
"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 pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
