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.

Effect local attack handling, intuitive interface, and scalable

The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution.

Client experience and cybersecurity have improved with an easy setup

The solution is valuable for client experience, especially in the financial sector. The most important feature is cybersecurity. The pricing is good, but the functionality is the most important aspect for clients. The solution is easy to deploy and requires only one person to set up, making it easy and quick. Overall, the ease of use and the fact that it meets client expectations are major positives.

Quotes from Members

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

Pros

"The tool is user-friendly."

"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."

"The DDoS protection is the most valuable aspect of the solution."

"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."

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

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."

"It is a fast and secure DNS."

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

More Cloudflare pros

"This is a hybrid solution."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."

"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."

"The most important aspect, in general, is that the price is suitable for most clients."

"The DDoS protection features are valuable."

"We're pretty happy with the API functionality. It's web, and it's very simple to set up queries. It has served us well and you don't need to be an expert on the API or the product to set these things up."

"Overall, the ease of use and the fact that it meets client expectations are major positives."

"One of the valuable features is the intuitive nature of building out reports, and then triggering actions based on specific metrics from those reports. It has a really good UI and the ability to surface data through the reporting functions is pretty good. That's helped a lot in the security space."

"I am able to do a lot of work on the visualization end to create different visualizations and different ways to get information out of it."

"Kentik excels in telemetry within data centers and works well in multi-vendor environments."

"The most valuable feature is being able to pull traffic patterns; to and from destinations. We're able to understand where our traffic is going, our top talkers from an AS set, as well as where our traffic's coming from."

"Having the API access allows us to do a great deal of automation around a lot of our reporting and management tools."

"I really love the Data Explorer. I use it all the time to go in and craft exactly what I need to see. I'm able to then take that story and explain it to the executives. I've done that a couple of times and it is helpful."

More Kentik pros

Cons

"The solution could be more user-friendly."

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."

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

"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."

"There might be helpful if there was some web application firewall feature."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"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."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

More Cloudflare cons

"The product must provide more Layer 7 capabilities."

"Lacks international presence."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"It could use support in Spanish."

"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."

"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."

"They're moving more in a direction where they are saying, "Hey, here's information that you may be interested in or may a need," before the question has to explicitly be asked. Continuing to move in that direction would be a good thing."

"I would like to see them explore the area of cost analysis."

"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."

"I've checked out the V4 version of the interface and it's still a little bit clunky for me to use. I still go back to the old interface. That's definitely one that they still need to work on. It doesn't seem like everything that you get in the V3, the older interface, is there. For instance, I was trying to add a user or do the administrative tasks in V4, and I couldn't figure out where I was supposed to do that."

"I consider the pricing model as an area for improvement."

"There is room for improvement around the usability of the API. It's a hugely complex task to call it and you need a lot of backing to be able to do it. I should say, as someone who's not in networking, maybe it's easier for people who are in networking, but for me that one part is not very user-friendly."

"The only downside to Kentik, something that I don't like, is that it's great that it shows you where these anomalies lie, but it's not actionable. Kentik is valuable, don't get me wrong, but if it had an actionable piece to it..."

"We asked for a way, regarding the potential networks that exist, to hook Kentik up with external tools like peering DBs to correlate things together and see what we can do... This is all in the [next] beta now."

More Kentik cons

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."

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

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

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

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

"So far I use free tier and happy with it. You can subscribe to business package if needed."

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

"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."

More Cloudflare pricing and cost advice

"The price of Corero is affordable."

"Its price is normal."

"We have an annual contract with Kentik that we renew each year for a set number of licenses. We also have some burstable licenses which we can spin up and spin down, and those are paid as they are used."

"The tool is cheaply priced."

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

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
