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…

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

"It is a fast and secure DNS."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"I selected CDN77 because it has servers where our different target markets are (some are in Asia)."
"CDN77 has helped improve load speed on the site."
"It has improved our organization by providing quick access to resources."

"It is extremely easy to set up and integrate with WordPress and purge files as needed through the control panel."
"It has helped improve load speed on the site."
"This is a hybrid solution."
"The DDoS protection features are valuable."
"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."
"It is a very efficient and robust appliance."
"I like the fact that the product provides 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."
"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 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."
 

Cons

"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."
"I rate technical support quite badly."
"Latencies are always a problem."
"We experienced some downtime in the fall of 2013, causing us to switch to Incapsula."
"I think they have failed with their technical support."
"The Always Online feature has room for improvement. It seems to work sometimes and not others even with the pro version."
"Integration involving API with other products could be more user-friendly."
"There should at least be a read-only view of the data so that resellers can properly support the clients."
"A year ago, I had to deal with SEO factors involving duplication of content."
"If you are a low-use user and not used the minimum credit, it will be lost at end of year unless you upgrade, then you are left with more bandwidth than you can ever use."
"If you are a low-use user and not used the minimum credit, it will be lost at end of year unless you upgrade, then you are left with more bandwidth than you can ever use."
"Regarding the pricing, it is expensive. It may not suit others."
"A year ago, I had to deal with SEO factors involving duplication of content."
"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."
"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."
"It could use support in Spanish."
"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."
"It could use support in Spanish."
"The product must provide more Layer 7 capabilities."
"Juniper is known in our country, but it is not very popular."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
 

Pricing and Cost Advice

"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"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 price of the solution is expensive."
"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."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"We are using the free tier of the solution."
"Regarding the pricing, it is expensive. It may not suit others. I suggest a lower recharge level and also to remove the credit expiry time​."
"For low-use users, it can be more expensive than it seems. It would be a disadvantage for a lot of hobby users."
"I would suggest low usage cases that there are other options available, such as WordPress's own CDN."
"Its price is normal."
"The price of Corero is affordable."
