Advanced protection has secured critical web workloads and provides clear traffic visibility
From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

Quotes from Members

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

Pros

"In my opinion, CloudFlare is one of the best CDN networks I have ever used."
"Cloudflare is easier to manage than the solutions provided by these vendors, and the user experience is much more straightforward and appeals to a lot of developers."
"The setup and configuration is also easy to perform and their support is excellent."
"Because our website is blazing fast it improves our conversion rates."
"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's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"This solution has improved the security of our organization."
"New and innovative way to protect the client's data."
"It is a very efficient and robust appliance."
"I like the fact that the product provides a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"The DDoS protection features are valuable."
"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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."
"The solution is very user-friendly and very easy to use."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"The product's initial setup phase was really easy."
"We have researched them all, and it's a good solution all around."
"Packet inspection has been effective for mitigating DDoS attacks."
"We've been completely satisfied with the product."
 

Cons

"The integration of LLMs on the dashboard is something that is needed in the tool."
"Yes, there were a few times when some of their CDN nodes would fail, creating serious speed issues with the site without any warning or notification from their side."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"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."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Technical support is lacking."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"The solution could work at being less expensive. It costs a lot to use it."
"It could use support in Spanish."
"Juniper is known in our country, but it is not very popular."
"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."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"The product must provide more Layer 7 capabilities."
"Lacks international presence."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."
"The solution can be a little more user-friendly and it can be more affordable."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"The price is reasonable."
