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.

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.

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.

"It is a fast and secure DNS."

"Centralized, full-featured DNS."

"The technical support is good."

"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

More Cloudflare pros

"The initial setup is easy and straightforward...Azure Web Application Firewall is a scalable product."

"Azure WAF is extremely stable."

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

"The return on investment is good."

"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."

"The solution has good dashboards."

"The integration it has with GitHub is great."

"It's great for protecting against DDoS attacks."

More Azure Web Application Firewall pros

"Compute@Edge features are valuable to me."

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

"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's initial setup phase is straightforward."

"Its initial setup process is straightforward."

Cons

"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."

"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."

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

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"The solution could work at being less expensive. It costs a lot to use it."

"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."

"The pricing could be improved."

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

More Cloudflare cons

"The knowledge base could be improved."

"The management can be improved."

"I would say that Azure's customer service is not that good...I am not very happy with the support offered."

"We would like to see additional site services using AI to provide information about blocking requests and offer analytics on the origin of calls."

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

"Azure WAF should not be deployed in the middle of the traffic."

"The documentation needs to be improved."

More Azure Web Application Firewall cons

"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."

"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."

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

"The solution's pricing could be better."

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

"Support is not that great."

Pricing and Cost Advice

"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."

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

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

"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."

More Cloudflare pricing and cost advice

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

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

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

"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.

Cloudflare can also help organizations of all sizes develop a robust zero-trust strategy to
ensure the highest levels of productivity and profitability. Employees, stakeholders, and end users have a greater level of satisfaction and overall improved user experience, which can, in
turn, result in higher revenues and overall ROI. Zero-trust and BYOD (bring your own device)
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
