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

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The UI is good."
"The solution provides good load balancing and protection against DDoS attacks."
"Easier http to https redirect using page rules"
"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. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"It is a fast and secure DNS."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The DDoS protection features are valuable."
"The most important aspect, in general, is that the price is suitable for most clients."
"This is a hybrid solution."
"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 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 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."
 

Cons

"Support response time could be improved."
"The product needs to improve its automation."
"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."
"The product support needs to be accessible from more places, a wider area of coverage."
"There should be a specific price list for enterprise-level customers."
"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're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Lacks international presence."
"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."
"It could use support in Spanish."
"The product must provide more Layer 7 capabilities."
"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."
 

Pricing and Cost Advice

"The product's pricing is cheap."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"We are using the free version."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The price is reasonable."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"That is one of the great features. I was able to access the majority of the features and services for free."
"I give the price a five out of ten."
"Its price is normal."
"The price of Corero is affordable."
