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).

A cost-effective choice for website security and informative support with issues related to CDN quality
One area where they could improve is in providing real-time support options because now you need to open a support ticket and wait for their response. It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance. I have found their Content Delivery Network service to be lacking in quality, and it could certainly be enhanced to provide better performance. I would also like to see improvements in the deployment process, as it currently takes more time than desirable. Another significant concern is that their service when your website is down, turns it into a static site. This means that if customers try to visit your site during downtime, they will see old content from the static site, which is not ideal. The CDN and tracking services are areas that need improvement, as well as addressing their bandwidth limitations.

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 solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"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 have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"The technical support on offer is excellent; they are very helpful and responsive, and we are quite happy with the level of service they provide to their customers."
"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The solution offers the flexibility to control configuration rules."
"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."
"The most valuable feature of F5 BIG-IP AFM is the iRules where I can customize the configuration."
"With controllers plus the firewall, you will only need one device to protect everything."
"The most valuable features of F5 BIG-IP Advanced Firewall Manager (AFM) are the web gateway, load balancing, services, and applications available."
"The most valuable feature of F5 BIG-IP AFM is all of my workers enjoy using it."
"The most valuable feature of this solution is the blocking of IPs and F5 has many advantages."
"The setup and functionality are fairly straightforward."
"It excels in preventing downtime and maintaining application performance, which is crucial for our clients' security and operational continuity."
"The solution provides behavioral analysis via AI to detect malicious traffic."
"The initial setup was straightforward. Straight forward because the plugin can simply be installed and then it does its job. It's not complex, there is no learning curve. The online scan is simple, you put in the website address and the scan gives us a report on the browser itself. It's simple to use."
"Domain name scanning since it allows us to scan all our domain names and determine whether it has malware or if is reported as phishing."
"The most valuable part is the analytics and visualization."
"Rather than locate some things manually, the Sucuri plugin scans and allows us to pinpoint whether there is malware or some problem in the site."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"The initial setup was very easy."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
 

Cons

"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"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."
"The product needs to improve its automation."
"The Always Online feature has room for improvement. It seems to work sometimes and not others even with the pro version."
"Several features that I think is essential is not available in the free and business package."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The pricing of the solution could be a little bit better."
"F5 could provide a distributed cloud version."
"Apart from the price, I feel no other areas need improvement."
"We would have preferred to have support when we first started"
"F5 should increase its capability to prevent zero-day attacks."
"NGINX, which F5 purchased, has room for improvement in its features, particularly its load balancing or application load balancing features."
"It is a little bit expensive, and I think about additional features they could have in the future to make it even better."
"This would be absolutely the best network security solution if the price were not so high."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"In terms of improvement, the cost factor is always there."
"The main improvement I would like to see is support for .NET applications. If they could include this feature, I would include more sites in the protection."
"I would rate this solution an eight out of ten. The reason is that we have found sometimes customers or Google saying that there is something wrong with the website but Sucuri says that the site is clean so we do have to look at the site manually which means that the Sucuri scan does not pick up anything and everything."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
 

Pricing and Cost Advice

"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 has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"The price of the solution is expensive."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"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."
"We need to pay a yearly licensing fee for the solution."
"It's very expensive, and you pay extra for the models."
"The product is expensive."
"F5 BIG-IP Advanced Firewall Manager is not an expensive solution."
"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."
"F5 BIG-IP AFM is an affordable solution. There were not any additional fees other than the standard licensing."
"The price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
"I’d simply say it’s really worth it."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
"The ROI has been very good. Because of the solution, I have a tax break. The site developers were not always experienced people. We used to pay more for cleaning up the site when it was infected. Now, we have peace of mind knowing that the solution will clean up the site and that we won't have to go through the unnecessary process of restoring it from a backup. The protection on the WAF and the measures for backups have also prevented our site from going down."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
