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

"The solution offers the flexibility to control configuration rules."
"We're partners with Cloudflare; this solution is the best product and it does not charge you for any kind of attack on your traffic, only for good traffic, and it can mitigate up to 30 TBPS of DDoS attacks."
"CloudFlare has positively improved my site's speed, performance and security."
"The solution provides good load balancing and protection against DDoS attacks."
"The setup and configuration is also easy to perform and their support is excellent."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"This solution has improved the security of our organization."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"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."
"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, and it is simple and works well if you have Juniper MX routers."
"The DDoS protection features are valuable."
"I like the fact that the product provides 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."
"Packet inspection has been effective for mitigating DDoS attacks."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"We have researched them all, and it's a good solution all around."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"We've been completely satisfied with the product."
"The protection resources and the support are valuable features of the solution."
"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."
 

Cons

"DNS Management."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"The Always Online feature has room for improvement. It seems to work sometimes and not others even with the pro version."
"At the end, it is worth than giving your house keys to the NSA."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"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."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"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."
"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."
"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."
"Juniper is known in our country, but it is not very popular."
"The product must provide more Layer 7 capabilities."
"I would like to see analytics, big data."
"Earlier versions of firmware had bugs that limit my options."
"The initial setup is complex. It is always complex."
"The product’s pricing needs improvement."
"The web interface could be much better."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
 

Pricing and Cost Advice

"A free version of the solution is available."
"There are no additional costs beyond the standard licensing fees."
"The product's pricing is cheap."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"The price is reasonable."
"The cost primarily depends on the size of the organization."
"I give the price a five out of ten."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
