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.

Quotes from Members

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

Pros

"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."

"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."

"It is a fast and secure DNS."

"The most valuable feature is its usability."

"The overall experience with Cloudflare is positive, with a rating of eight out of ten."

"Cloudflare has many features."

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

"The solution is stable, and the DNS servers are simple to use."

More Cloudflare pros

"Our customers are more than satisfied with the user experience provided by the product."

"F5 helped to meet compliance and regulatory requirements."

"The most valuable features of F5 Advanced WAF are the balancer and you can change policies very easily."

"Feature-wise, they are always cutting edge and up-to-date. Many features aren't available via competitors. There's always a lot of enhanced critical features that just aren't available through anyone else, or, if they are, are too lightweight."

"The anti-bot protection is the solution's most valuable feature. Safe-guard or credential staffing are also useful features."

"WAF functionality is valuable for protecting applications from attacks."

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

"The best solution for WAF."

More F5 Advanced WAF pros

Cons

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."

"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."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"The integration of LLMs on the dashboard is something that is needed in the tool."

"The product support needs to be accessible from more places, a wider area of coverage."

"In the last two years, there has been a certain amount of downtime when using the VDM."

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

More Cloudflare cons

"The tool must be simplified."

"The overall price of F5 Advanced WAF could improve."

"The reporting portion of F5 Advance WAF is not great. They need to work out something better, as it is very basic. You only see the top IPs, I think there is more they can offer."

"More legacy protocols should be added to the solution."

"The GUI interface can be confusing due to similar-looking tabs for policy building, traffic learning, and event logs."

"I would like to see the API Protection improved."

"There should be more ability to rate limit certain scenarios. The majority of the time, it is either on or off. For certain types of use cases, there should be the ability to rate limit, not just enable or disable."

"You have to buy another module with an extra license, to have the authentication feature."

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

More F5 Advanced WAF cons

"The price of the solution is expensive."

"We are using the free version."

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

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

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

“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
