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…

A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"If it was not for CloudFlare, I would have to hire a dedicated resource to manage all this for me."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."
"The solution is very good at mitigating threats."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"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."
"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."
"I like the fact that the product provides a hybrid solution."
"This is a hybrid solution."
"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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The DDoS protection features are valuable."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
"Nexusguard has exponentially improved the availability of our services because we don't have to worry much about any threats or DDoS attacks towards our services."
"The support team was helpful."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
"Nexusguard has given us confidence that we are protected against any outside attacks."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
 

Cons

"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."
"There are some issues with the CDN services."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"Technical support is lacking."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"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."
"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 product must provide more Layer 7 capabilities."
"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."
"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."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"Lacks international presence."
"One of the features that should be added to the next release is report generation."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
 

Pricing and Cost Advice

"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."
"The tool is a premium product, so it is very expensive."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"I give the price a five out of ten."
"The price of Corero is affordable."
"Its price is normal."
"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
