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

"If it was not for CloudFlare, I would have to hire a dedicated resource to manage all this for me."
"The aggressive caching and DDOS mitigation are the most valuable features offered by Cloudflare."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."
"It is a fast and secure DNS."
"The setup and functionality are fairly straightforward."
"The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications."
"This product excells in every aspect from installation and the interface to providing superior network security."
"The product’s most valuable features are LTM and WAF."
"What I find most impressive about F5 is that, as long as you know what you want to do, as long as we know what you want to achieve, you find the solution there."
"It blocks various attacks and mitigates disasters from occurring."
"It excels in preventing downtime and maintaining application performance, which is crucial for our clients' security and operational continuity."
"F5 BIG-IP Advanced Firewall Manager's most valuable feature is load balance. It is readily available and uncomplicated."
"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."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
"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 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."
"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."
"The initial setup was very easy."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
 

Cons

"Honestly the product has not really improved the way of my organisation."
"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."
"The documentation could improve for Cloudflare DNS."
"The solution could work at being less expensive. It costs a lot to use it."
"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."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"For the services I am using, it is a bit expensive."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider 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."
"The web gateway feature could improve in F5 BIG-IP Advanced Firewall Manager (AFM)."
"If you compare it with the next-generation firewalls, then definitely this tool is not comparable."
"The pricing of the solution could be a little bit better."
"F5 BIG-IP Advanced Firewall Manager's pricing and technical support services need improvement."
"It is a little bit expensive, and I think about additional features they could have in the future to make it even better."
"There is room for improvement in Advanced Firewall Manager's dashboard statistics, especially during attacks."
"The product is expensive."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The price is reasonable."
"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."
"We are using the free version."
"The product's pricing is cheap."
"The tool is a premium product, so it is very expensive."
"The cost primarily depends on the size of the organization."
"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."
"The price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
"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."
"We need to pay a yearly licensing fee for the solution."
"The solution is slightly on the higher priced side."
"It's very expensive, and you pay extra for the models."
"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."
"F5 BIG-IP AFM is an affordable solution. There were not any additional fees other than the standard licensing."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
"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."
"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."
