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 has many features."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The most valuable feature is its usability."
"From what I've seen so far, there are no negatives to report as of yet"
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"In my opinion, CloudFlare is one of the best CDN networks I have ever used."
"The UI is good."
"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 a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"It is a very efficient and robust appliance."
"This is a hybrid solution."
"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."
"The DDoS protection features are valuable."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The protection resources and the support are valuable features of the solution."
"The most valuable feature is the cloud DDoS scrubbing capability."
"The solution is very user-friendly and very easy to use."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"Packet inspection has been effective for mitigating DDoS attacks."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
 

Cons

"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"More insight into analytics and threats would be a good place to start improving Cloudflare."
"Integration involving API with other products could be more user-friendly."
"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."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"Lacks international presence."
"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."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"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 challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The web interface could be much better."
"The product’s pricing needs improvement."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"Alerts and reporting features must be improved."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution can be a little more user-friendly and it can be more affordable."
"I would like to see analytics, big data."
 

Pricing and Cost Advice

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"The tool is a premium product, so it is very expensive."
"A free version of the solution is available."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is minimal compared to other products."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We are using the free tier of the solution."
"We don't have any issues with the price."
"The price of Corero is affordable."
"Its price is normal."
"The product’s pricing needs improvement."
"It's quite pricey."
"The solution is reasonably priced."
