Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Mano Senaratne - PeerSpot reviewer
Comprehensive suite simplifies configuration while frequent updates require management
Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.
Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.

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 is the web application firewall."
"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."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"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."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Generally, I am satisfied with this product."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"We have found the most valuable features to be the web application, minimal skills required for management, control through policies, and automation."
"The most valuable feature of Azure Web Application Firewall is its ability to filter requests and block false positives by using custom rules and the OWASP rule set."
"It's a good option if you want a solution that's ready to go and easy for your team to learn. It's cloud-based, so you don't need to buy or maintain any hardware infrastructure."
"It's quite a stable product and works well with Microsoft products."
"Configuration is much easier than using different platforms."
"It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure."
"The integration it has with GitHub is great."
"Azure WAF is extremely stable."
"The product's initial setup phase is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"The product helps our organization to access sites located in different regions quickly."
"Compute@Edge features are valuable to me."
"Its initial setup process is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
 

Cons

"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"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 reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"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."
"Latencies are always a problem."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"We would like to see additional site services using AI to provide information about blocking requests and offer analytics on the origin of calls."
"The management can be improved."
"The knowledge base could be improved."
"The documentation needs to be improved."
"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."
"I would say that Azure's customer service is not that good...I am not very happy with the support offered."
"Some Azure applications, like the web application firewall, require a certain level of SKU for hosting setup. The basic setup does not allow me to use the web application firewall and other additional services."
"The support for proxy forwarding could improve."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"What I don't like about Fastly is that they charge a heavy price."
"Support is not that great."
"The solution's pricing could be better."
"Fastly's customer service area needs improvement."
"The product should provide improved bot detection and management."
 

Pricing and Cost Advice

"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."
"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 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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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 tool is a premium product, so it is very expensive."
"The price is for this solution is fair and there is a license needed."
"I give the pricing a nine out of ten."
"The price is reasonable. It is approximately $2,000 US per month."
"Azure WAF has price advantages over other WAF solutions. The pricing model is flexible because you pay on a scale based on the level of protection you need."
"We have an enterprise agreement with Microsoft and the pricing is good."
"The price of the solution depends on your architecture and how you manage it. You can control the cost in Azure quite well. The costs do not directly correlate to expenses in the features we are using."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Fastly is less expensive than one of its competitors."
"You need to pay a premium price for the tool."
"It is an expensive solution."
"In my opinion, Fastly is priced competitively."
"The pricing has been very competitive."
"The solution is cheaper than other products in the market."
