Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

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.

Managed security rules have protected our public e‑commerce sites and simplified ongoing defense

I advise anyone looking for a great tool to secure their public-facing applications to start using F5 Rules for AWS WAF. These are managed rule sets, so you do not need to worry about continuous improvements or ensuring your application is secure; F5 Rules for AWS WAF will take care of that and is always making the necessary improvements in these rule sets to ensure security. I am very impressed with the rule sets and the continuous engineering from their security team to ensure the required rule set availability. I really appreciate the fantastic job they are doing. F5 Rules for AWS WAF can be integrated with AWS CloudFront, Application Load Balancer, Lambda, and API Gateway. I am satisfied with all these services as they are our intermediary points for services exposed to the public or globally. I gave this product a rating of ten out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

"I like Cloudflare's application gateway and DDoS protection."

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"The technical support is good."

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."

"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."

"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."

More Cloudflare pros

"It has been a stable product in my experience."

"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."

"The most valuable feature is that it allows us to publish our applications behind the firewall."

"I can only strongly recommend using the Azure Web Application Firewall."

"The Microsoft support and the analytics are what I appreciate about Azure Web Application Firewall; it integrates effectively with things such as Sentinel and Defender for Cloud, so mostly it's the analytics and now the AI capabilities that have been introduced with Co-pilot."

"The best features of Azure Web Application Firewall are that it provides security and protection from poorly designed web applications."

"It's quite a stable product and works well with Microsoft products."

"Configuration is much easier than using different platforms."

More Azure Web Application Firewall pros

"I advise anyone looking for a great tool to secure their public-facing applications to start using F5 Rules for AWS WAF."

"F5 Rules for AWS WAF has positively impacted our organization for security through the implementation of traffic rules in our application."

"I advise anyone looking for a great tool to secure their public-facing applications to start using F5 Rules for AWS WAF."

Cons

"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."

"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."

"The product needs to improve its automation."

"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."

"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."

More Cloudflare cons

"The management can be improved."

"The documentation needs to be improved."

"The support for proxy forwarding could improve."

"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."

"Deployment should be simplified so that a non-techie can handle it."

"Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead."

"There is a need to be able to configure the solution more."

"From my point of view, there is no need for improvement."

More Azure Web Application Firewall cons

"An area for improvement I see is that while everything is in good shape, I demand continuous improvisation of these rule sets."

"It's too early to talk about a return on investment with F5 Rules for AWS WAF."

"An area for improvement I see is that while everything is in good shape, I demand continuous improvisation of these rule sets."

Pricing and Cost Advice

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"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."

"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."

"The tool is a premium product, so it is very expensive."

"We are using the free version."

"The price is reasonable."

"We don't have any issues with the price."

"I give the price a five out of ten."

More Cloudflare pricing and cost advice

"I give the pricing a nine out of ten."

"The price is for this solution is fair and there is a license needed."

"The price is reasonable. It is approximately $2,000 US per month."

"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."

"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."
