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.

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.

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 solution is very good at mitigating threats."

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

"It is easier to configure and develop documentation to see how we have configured firewalls."

"The most valuable features of the solution are performance and security."

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

"Easier http to https redirect using page rules"

"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."

"It is a fast and secure DNS."

More Cloudflare pros

"Its initial setup process is straightforward."

"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."

"The product's initial setup phase is straightforward."

"Rate limiting is a good feature that protects from volumetric attacks."

"Compute@Edge features are valuable to me."

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

"The most valuable feature of Citrix ADC is its ease of use."

"Compared to other solutions, Citrix ADC is much more robust in terms of the native integration to cloud platforms. It is far more robust from an operational point of view as well."

"Citrix is good for application protection."

"The solution is easy to work with and manage."

"My clients use it for load balancing."

"Load Balancing and SSL offloading are key features."

"It is the best product out there."

"Most of the functions are user-friendly and great."

More NetScaler pros

Cons

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."

"There are some issues with the CDN services."

"Cloudflare should add more documentation and pricing to the cloud version."

"The documentation could improve for Cloudflare DNS."

"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."

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

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

"The solution could be more user-friendly."

More Cloudflare cons

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

"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 product should provide improved bot detection and management."

"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."

"Fastly's customer service area needs improvement."

"Support is not that great."

"The solution's pricing could be better."

"They can improve the scalability and the multi-tenancy feature. We recently tried to configure an authentication, and we ran into some issues while using the web-based GUI. It was very slow when you log in with your credentials in the web-based GUI. Each time we clicked on the menu, it tried to do the authentication. It works properly in the console."

"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."

"We would like to see some fairly large scale improvement in the configuration process for this solution."

"When a new version comes out, sometimes, my existing configuration gets wiped out. They should work on this so that my existing configuration doesn't get impacted with an upgrade to a newer version. There could also reduce frequent firmware upgrade activities and have a stable version so that once we upgrade it, we don't have to upgrade it for two to three years."

"The GUI should be improved."

"The solution should be able to scale more effectively than it does."

"The solution could be more secure."

"Citrix is more expensive than Horizon."

More NetScaler cons

Pricing and Cost Advice

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

"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."

"The product's pricing is minimal compared to other products."

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

"The product's pricing is cheap."

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

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

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

More Cloudflare pricing and cost advice

"The solution is cheaper than other products in the market."

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

"The pricing has been very competitive."

"It is an expensive solution."

"Fastly is less expensive than one of its competitors."

"In my opinion, Fastly is priced competitively."

"You need to pay a premium price for the tool."

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

"F5 BIG-IP is much more expensive than Citrix ADC. For example, If we choose two platforms, Citrix ADC, 3000 version, and we choose F5, F4200 version. F5 BIG-IP has connections, timers, and throughput similar to Citrix ADC, but the price is very expensive."

"Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much."

"This product is more expensive than some of the competitors."

"I do not have any experience with the pricing of the product."

"The pricing could be lower."

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

"It's not for startups or SOHO."

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
