Featured Reviews

Spencer Malmad

Owner at Tech Exchange

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.

Easy event identification, highly stable, and customizable

Generally, F5 Advanced WAF initial setup is straightforward. However, our environment was more complex and it took us a little more time to customize the solution to where we needed it to be. Additionally, the customization didn't rectify everything. We had to do customization to a certain event to prevent attacks that it wasn't catching, but that might not necessarily be the solutions' fault. It could be more of our setup than the solution's fault and not being able to run the latest version or the newer version could be more of a limitation on our ability to put it in the right place. The whole implementation to have the solution run at the level we wanted it to take approximately five months. Our company's environment is one that we can't put a canned solution in front of. Our environment, cannot have a canned solution that might fit everybody else because of how customized this environment is. It does need a lot of tuning to meet our environment's requirements. I rate the initial setup of F5 Advanced WAF a three out of five.

CEO at Torque

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 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."

"Generally, I am satisfied with this product."

"The UI is good."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"It's very user-friendly."

"The tool is user-friendly."

"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."

"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."

More Cloudflare pros

"The most valuable features of F5 Advanced WAF are the security features and the protection."

"It ensures compliance with security standards by providing features like PCI DSS checks."

"It also has antivirus and DDoS mitigation capabilities. We have enabled these features."

"I like the security features, especially against SQL injection."

"This solution inspects your traffic and based on that, automatically create distinct qualities for you, so you can add this to the policy already created. That's what I like most."

"With F5 Advanced WAF, it was protection for online publications and for our customers that caused us to choose the platform."

"The most valuable features of F5 Advanced WAF are the easy identification of events and customization. We can pinpoint our settings."

"Web attack signatures are very important for detecting web attacks."

More F5 Advanced WAF pros

"The product helps our organization to access sites located in different regions quickly."

"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."

Cons

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

"There should be a specific price list for enterprise-level customers."

"The documentation could improve for Cloudflare DNS."

"The product needs to improve its automation."

"The solution could be more user-friendly."

"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."

"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."

More Cloudflare cons

"The solution's dashboard could be improved. When you're moving from policy to policy, the logs and the integration of the logs in other systems aren't straightforward."

"One improvement for AOF could be focusing on enhancing its AI engine to make it more mature."

"People who want to work with the device have to be pro in Linux"

"I would like for there to be a cloud-based solution, this would also help to improve scalability."

"I would like to see improved features in the F5 Advanced WAF solution, especially with a focus on enabling Kubernetes fully."

"The contextual-based component needs a lot of help to catch up with the next-gen products."

"The accuracy of the automatic learning feature needs improvement."

"It's a powerful tool yet can be complex for new users."

More F5 Advanced WAF cons

"Support is not that great."

"Fastly's customer service area needs improvement."

"What I don't like about Fastly is that they charge a heavy price."

"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."

"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."

"The solution's pricing could be better."

"The product should provide improved bot detection and management."

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"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."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"There are no additional costs beyond the standard licensing fees."

"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 price is reasonable."

"We are using the free tier of the solution."

More Cloudflare pricing and cost advice

"The solution is very expensive so should only be used in the right environment."

"I think the price is very high."

"The cost is slightly above average."

"The price of the solution is reasonable when compared with other products, such as FortiWeb. I am very satisfied with the price."

"F5 Advanced WAF's pricing is high."

"I rate F5 Advanced WAF's pricing a three out of ten."

"I don't have any issue with the pricing of this solution."

"It is expensive. Its price should be better. Its licensing is on a yearly basis. Its licensing is also based on the model. There are no additional costs."

More F5 Advanced WAF pricing and cost advice

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."

Overview

Cloudflare is a highly-regarded Content Delivery Network (CDN) and a Distributed Denial-of-Service (DDoS) protection solution. The robust global connectivity cloud platform that is Cloudflare ensures users are able to connect to the Internet quickly, securely, and reliably. Cloudflare is one of the world's largest networks in the marketplace today. Using Cloudflare, businesses, educational entities, NGOs, vloggers, bloggers, and anyone else with an internet presence can experience more secure, faster websites and applications.

Currently, there are millions of Internet locations on Cloudflare, and the Cloudflare network
continues to grow every day by the thousands. The solution is able to fulfill the requests for
millions of websites seamlessly and serves on average 45 million HTTP requests per second.

Cloudflare has safe, secure data centers in close to 300 cities worldwide to ensure every
client request is filled as quickly as possible. It is Cloudflare’s edge network that makes this
possible by keeping content and other services as close to each client as possible, so the
information requests are always only seconds away.

Many organizations that work in democracy, civil society, human rights, or the arts are able to
access Cloudflare's highest levels of protection for free via Project Galileo. Additionally, official
election websites can be secured from hacking and fraud through Cloudflare’s Project
Athenian, also at no additional cost.

access ensure end users and employees always have the best resources and technology
available to them at all times.

Reviews from real users

“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. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“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.” PeerSpot user, Competence Center Manager at a tech services company
