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

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The most valuable feature of Cloudflare DNS is security."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"The most valuable features of the solution are performance and security."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"The return on investment is good."
"It's great for protecting against DDoS attacks."
"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 most valuable feature is that it allows us to publish our applications behind the firewall."
"It has been a stable product in my experience."
"The integration it has with GitHub is great."
"Azure WAF is extremely stable."
"I can only strongly recommend using the Azure Web Application Firewall."
"Its initial setup process is straightforward."
"The product's initial setup phase is straightforward."
"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."
"Rate limiting is a good feature that protects from volumetric attacks."
"Compute@Edge features are valuable to me."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The product helps our organization to access sites located in different regions quickly."
 

Cons

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"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 would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Integration involving API with other products could be more user-friendly."
"DNS Management."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"The support for proxy forwarding could improve."
"The management can be improved."
"The documentation needs to be improved."
"There is a need to be able to configure the solution more."
"We would like to see additional site services using AI to provide information about blocking requests and offer analytics on the origin of calls."
"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."
"Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead."
"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."
"Support is not that great."
"Fastly's customer service area needs improvement."
"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."
"What I don't like about Fastly is that they charge a heavy price."
"The product should provide improved bot detection and management."
"The solution's pricing could be better."
"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."
 

Pricing and Cost Advice

"The product's pricing is cheap."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"We don't have any issues with the price."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The tool is a premium product, so it is very expensive."
"There are no additional costs beyond the standard licensing fees."
"The price of the solution is expensive."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"We have an enterprise agreement with Microsoft and the pricing is good."
"The price is for this solution is fair and there is a license needed."
"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."
"The price is reasonable. It is approximately $2,000 US per month."
"I give the pricing a nine out of ten."
"It is an expensive solution."
"In my opinion, Fastly is priced competitively."
"The pricing has been very competitive."
"You need to pay a premium price for the tool."
