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.

Comprehensive network protection has mitigated DDoS risks and supports secure on-prem operations
Currently, there are no weaknesses or disadvantages in F5 BIG-IP Advanced Firewall Manager (AFM) that I have identified. It is a little bit expensive, and I think about additional features they could have in the future to make it even better. For example, I have thoughts about the price. Currently, it does not integrate, and I would assess the importance of F5 BIG-IP Advanced Firewall Manager (AFM)'s integration with cloud services as significant. Currently, I use only one site, and I cannot tell you about F5 BIG-IP Advanced Firewall Manager (AFM) centralized security policies. I have not used F5 BIG-IP Advanced Firewall Manager (AFM)'s Threat Intelligence capabilities. I have not used their dynamic traffic shaping feature. So far, the only thing that could be improved is the pricing of F5 BIG-IP Advanced Firewall Manager (AFM).

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through
Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

Quotes from Members

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

Pros

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic."
"The setup and configuration is also easy to perform and their support is excellent."
"The UI is good."
"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."
"It is a fast and secure DNS."
"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."
"The tool is user-friendly."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The customer service is excellent, and I rate it ten out of ten."
"With controllers plus the firewall, you will only need one device to protect everything."
"The product helps us provide security validation by protecting various applications from getting hacked."
"The most valuable features of F5 BIG-IP Advanced Firewall Manager (AFM) are the web gateway, load balancing, services, and applications available."
"The solution is very straightforward, and the usability is great."
"F5 BIG-IP Advanced Firewall Manager's most valuable feature is load balance. It is readily available and uncomplicated."
"The decryption is great."
"Its performance and ease of use are valuable."
"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."
"Scalability is awesome, and they have grown two folds or three folds since we started using them, with no concerns even as we protect close to 60,000 hosted sites for business and e-commerce customers."
 

Cons

"I think they have failed with their technical support."
"We experienced some downtime in the fall of 2013, causing us to switch to Incapsula."
"Latencies are always a problem."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"I rate technical support quite badly."
"It looks like they don't support as many TLDs as other registrars, but since they are very new as a registrar, I expect this may improve soon."
"Integration involving API with other products could be more user-friendly."
"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."
"Currently, we have eighty F5s and we need some kind of management software. It would be very helpful."
"We needed to protect the database but the solution didn't offer a certain feature to do so."
"There is room for improvement in Advanced Firewall Manager's dashboard statistics, especially during attacks."
"The solution doesn't really meet our requirements for an edge firewall."
"The solution's UI could be improved."
"Deployment times vary according to the customer. It needs to be heavily configured."
"If you compare it with the next-generation firewalls, then definitely this tool is not comparable."
"It doesn't compare to next generation firewalls"
"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."
"Genuine traffic coming in is still getting better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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 cost primarily depends on the size of the organization."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"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."
"We have purchased a five-year licensing package for the product."
"As per pricing, I would not say cheap, but little higher than cheap, but not very expensive. So you can say kind of value for money solutions."
"It is somewhat on the expensive side although it is worth the additional cost."
"The price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
"The product is expensive."
"F5 BIG-IP Advanced Firewall Manager is not an expensive solution."
"We need to pay a yearly licensing fee for the solution."
"F5 BIG-IP Advanced Firewall Manager (AFM) is an expensive solution. They are one of the best in the market, but the price could be cheaper."
