Spencer Malmad - PeerSpot reviewer
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.

Provides great security with a good application firewall
The initial setup is straightforward. If you want to use the portal, CLI, or PowerShare, or you want to use automation data for one month, it's straightforward. Even when it comes to operational maintenance, it's pretty easy and straightforward. Microsoft has done a great job on that front. Maintenance generally requires someone who is a cloud administrator or similar to maintain services in general, with Front Door a small piece of a larger maintenance requirement. There's not a lot to manage, the configuration is simple. I encourage people to document the configuration and infrastructure as well as disaster recovery in case anything happens.
Archana Heeralal - PeerSpot reviewer
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

"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."
"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 tool is user-friendly."
"The solution is very good at mitigating threats."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"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 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 solution offers the flexibility to control configuration rules."
"The price is one of the most important aspects of the product. It's quite affordable."
"The web application firewall is a great feature."
"I am impressed with the tool's integrations."
"The most valuable feature is that you can implement resources globally. It does not depend on location and ability or something like that. This is to connect clients around the world."
"Has a great application firewall and we like the security."
"You can assign as many web application firewall policies as you want to the same instance of Front Door."
"It inspects the traffic at the network level before it comes into Azure. We can do SSL offloading, and it can detect abnormalities before the traffic comes into the application. It can be used globally and is easy to set up. It is also quite stable and scalable."
"I particularly appreciate its load-balancing capabilities as it allows us to manage multiple instances and support a global presence effectively."
"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."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"Latencies are always a problem."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"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."
"The analytics, basically the dashboard, doesn't have much to it."
"DNS Management."
"An integrated SSO feature would be useful for Cloudflare DNS."
"The solution could work at being less expensive. It costs a lot to use it."
"The user interface needs improvement as it is difficult to create the mapping to link the problem with your private address sources."
"The tool should improve its cost."
"There is room for improvement and they're working on it."
"It lacks sufficient functionality."
"The product needs to improve its latency."
"I'm responsible for the governance and cost control of Azure. I'm not a specialist in any products and therefore I couldn't really speak effectively to features that are lacking or missing."
"My suggestion for improvement would be to enhance the Data Export feature to include specific tables, particularly the Azure Diagnostics table."
"The product's features are limited compared to Cloudflare. The tool also doesn't work well in a hybrid environment. I would like to see a way to add personalized APIs in the system."
"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."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"There are no additional costs beyond the standard licensing fees."
"The tool is a premium product, so it is very expensive."
"The price of the solution is expensive."
"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."
"We don't have any issues with the price."
"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."
"The cost primarily depends on the size of the organization."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"It is on a pay-as-you-go basis."
"The product is expensive."
"The pricing of the solution is good."
"The transition to the premium tier has led to increased costs, making it more expensive than the classic tier."
"Considering the standard licensing of the tool, even though we have not checked the billing as of now, it might not be very costly."
"The solution is a bit expensive."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
