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.

A tool for centralized management including inventory and sales tracking

Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

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 DNS is its global reach and it is always evolving."

"The solution is very good at mitigating threats."

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

"The solution offers the flexibility to control configuration rules."

"Smaller businesses have seen great ROI due to the low investment and strong performance."

"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."

"Centralized, full-featured DNS."

"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

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

"When our primary link goes down I can still get to my Cisco devices and the NetScaler devices on-prem because of the SDN solution. If the internet connection at one of the branches goes down, we can still route them, they still get internet based on the SDN solution through one of the other sites. They can carry on working."

"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."

"The maintenance of the solution is not complex."

"I like the solution's simplicity compared to Citrix's on-prem solutions."

"The solution is very stable. We don't have any downtime or issues of that nature."

"The most valuable feature for us is the application firewalling in Citrix NetScaler, ensuring only valid traffic enters our environment."

"Content filtering, security layer, and application customization features are the most valuable."

"The work balancing applications are the most valuable feature."

More NetScaler pros

Cons

"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."

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."

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

"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."

"The pricing could be improved."

"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."

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

"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."

More Cloudflare cons

"The tool must be simplified."

"Mastering it requires significant learning and training due to its complexity."

"I would like to see multifactor authentication added to this solution to improve the security."

"I would like to see more integration for single sign-on."

"Technical support could be improved."

"In every release - and it doesn't matter if it's a minor release or a major release - they keep moving things around and they keep changing the mechanism. So certain things can work in one version one way, and everything works really well, then when you upgrade it to the next version, it breaks everything because they have a new way of doing it."

"I would like to see support for scripting, like "iRule", which gives you the option to implement any configuration which is not available out of the box."

"The licensing model and technical support of the solution could be improved."

"We would like the licensing model for this product to be improved, as it isn't currently very transparent. There isn't a standard package available, and each extra feature creates an additional cost."

More NetScaler cons

Pricing and Cost Advice

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

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"We are using the free version."

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

"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 cost primarily depends on the size of the organization."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"The price is reasonable."

More Cloudflare pricing and cost advice

"The tool is cheap."

"We are quite happy with price. It's not too high."

"After deployment, Citrix Netscaler shifted to a subscription-based license scheme for support, which is slightly more expensive."

"Citrix NetScaler's pricing is slightly above average but not overly expensive. I would consider F5 BIG IP to be the most expensive, Citrix NetScaler to be the second most expensive, and then Kemp Load Balancer to be the third."

"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."

"It is an enterprise solution. Thus, its costs are reasonable."

"The firewall license is included by default, with no additional costs."

"It all depends on the features that will be used and the number of accesses."

"I rate the pricing an eight out of ten since it is expensive."

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

Airlock Suite deals with the issues of filtering and authentication in one complete and coordinated solution - setting new standards for usability and services.

Ergon Informatik

One platform for a consistent application delivery and security experience because nobody has time to learn multiple systems to manage ADC deployments. NetScaler is built with a single code base using a software-based architecture, so no matter which ADC form factor you choose — hardware, virtual machine, bare metal, or container — the behavior will be the same.
