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

"Another reason it's awesome is that you don't need your server to handle every request."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."
"The most valuable feature is the web application firewall."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"DDoS protection is this product’s most valuable feature."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"This product excells in every aspect from installation and the interface to providing superior network security."
"We use the solution for load balancing and WAF (web application firewall)."
"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."
"Its performance and ease of use are valuable."
"It is a highly stable solution."
"We use three main features. The first one is access control. The second feature we use is called IP intelligence. Finally, we have a DDoS safety feature."
"The product helps us provide security validation by protecting various applications from getting hacked."
"The initial setup was very easy."
"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."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
"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."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"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."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
 

Cons

"The pricing could be improved."
"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."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."
"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."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"Several features that I think is essential is not available in the free and business package."
"The web gateway feature could improve in F5 BIG-IP Advanced Firewall Manager (AFM)."
"Apart from the price, I feel no other areas need improvement."
"The pricing of the solution could be a little bit better."
"We would have preferred to have support when we first started"
"F5 should increase its capability to prevent zero-day attacks."
"For configuring the firewall, every single vendor on the planet has pretty much the same logic when it comes to firewalls, and F5 has a completely different approach and completely different behavior."
"F5 BIG-IP AFM can improve the reporting interface in relation to advanced troubleshooting depending on CLI. They should have enhanced troubleshooting with the use of GUI."
"Currently, we have eighty F5s and we need some kind of management software. It would be very helpful."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"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."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
"In terms of improvement, the cost factor is always there."
 

Pricing and Cost Advice

"The product's pricing is minimal compared to other products."
"The tool is a premium product, so it is very expensive."
"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 is reasonable."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The price of the solution is expensive."
"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."
"F5 BIG-IP AFM is an affordable solution. There were not any additional fees other than the standard licensing."
"F5 BIG-IP Advanced Firewall Manager is not an expensive solution."
"The solution is slightly on the higher priced side."
"We need to pay a yearly licensing fee for the solution."
"The product is expensive."
"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."
"The price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
"I’d simply say it’s really worth it."
"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."
