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…

Strong policies and bot defenses have secured critical APIs and have reduced attack noise
From my research regarding the IAM space that Imperva Application Security Platform is trying to look into, I believe they still need to do a lot of modeling and modification to make sure that also helps. There are several competitors in the IAM space, so Imperva would do well if they can do some basic modeling and modifications from my own personal research and my own experience in the IAM space. Alternatively, they could actually just focus on trying to be stronger in the web application space and the database activity monitoring space.The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum. There are times when clients could have urgent issues to attend to. The support team could do more by having a faster response rate.

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."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"Generally, I am satisfied with this product."
"Cloudflare is easier to manage than the solutions provided by these vendors, and the user experience is much more straightforward and appeals to a lot of developers."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."
"Because our website is blazing fast it improves our conversion rates."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"I like the fact that the product provides a hybrid solution."
"The DDoS protection features are valuable."
"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."
"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."
"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 very efficient and robust appliance."
"The solution is really stable; it's a product that I can stand by and recommend because I know it's going to work for the customer."
"Protection is the best solution since it has profile functionality."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."
"Incapsula provides a very simple to install and configure solution, that can be up and running in minutes."
"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."
"Imperva DDoS is fairly stable, and its availability is quite high."
"The setup of Imperva DDoS was easy and we are satisfied with the pricing."
 

Cons

"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"I would like to not need a separate server for non-www redirection under the CNAME setup option."
"DNS Management."
"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."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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."
"Juniper is known in our country, but it is not very popular."
"The product must provide more Layer 7 capabilities."
"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 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."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"Support is one thing I wish Imperva could improve."
"Pricing can be improved, as it is quite expensive."
"Technical support is probably the biggest drawback."
"Imperva Web Application Firewall is very expensive."
"It would be helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default."
"On the negative side, API security mainly supports cloud-based solutions, while most of my customers prefer on-prem setups, so achieving high performance with on-prem solutions would be beneficial."
"Management of policies and rules can be complicated and the physical setup of the product has implications on HA."
"The product could use a broader scope in the area of policies."
 

Pricing and Cost Advice

"The product's pricing is minimal compared to other products."
"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."
"There are no additional costs beyond the standard licensing fees."
"I give the price a five out of ten."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The product's pricing is cheap."
"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."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The price of Corero is affordable."
"Its price is normal."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"Imperva Web Application Firewall's pricing is expensive."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"Pricing could be more competitive."
"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"The solution's pricing is an issue."
"The tool's pricing is good."
