Solution provides essential protection with good support and a simple setup

I have noticed a pattern developing in approximately five minutes. If it were possible to provide these patterns with historical data spanning six months, three months, or two months directly from the console, it would be extremely beneficial. It would allow for easy inquiries and facilitate the retrieval of relevant parts without having to manually check logs or examine movements. Instead, if all historical data were available, I could consult six months' worth of identified patterns efficiently through AWS without relying on external sources. This solution is particularly suitable for startups or medium-sized startups. I would rate the overall solution eight out of ten.

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.

Quotes from Members

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

Pros

"The product has a good mechanism to analyze trends and trigger events."

"It is integrated with AWS. So, it gives you a good first step."

"It is quite scalable, and we have not faced any issues with its scalability."

"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."

"The product is easy to use."

"The solution's ease of use is the most valuable feature."

"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."

"I am impressed with the product's multiple features like security."

"The most valuable feature is the web application firewall."

"The solution is very good at mitigating threats."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"From what I've seen so far, there are no negatives to report as of yet"

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

"The solution provides good load balancing and protection against DDoS attacks."

"The tool is user-friendly."

"The most valuable feature of Cloudflare DNS is security."

More Cloudflare pros

Cons

"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."

"The product should give users more flexibility to customize their security policies according to their requirements."

"The product is expensive."

"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."

"The product needs to improve its logs and reports to make it read better."

"We end up having to pay extra for features that AWS adds that we don't need."

"Perhaps the time required to detect anomalies can be reduced."

"The time taken to detect anomalies must be reduced."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"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."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."

"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."

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

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

More Cloudflare cons

Pricing and Cost Advice

"We pay $3000 per month for the solution."

"The tool's pricing is good."

"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."

"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."

"The tool is cheap."

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

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

"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."

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

"The price of the solution is expensive."

"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."

Overview

AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards applications running on AWS. AWS Shield provides always-on detection and automatic inline mitigations that minimize application downtime and latency, so there is no need to engage AWS Support to benefit from DDoS protection.

Amazon Web Services (AWS)

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
