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.

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

"The solution automatically detects and responds to certain types of traffic based on geolocation."
"If it was not for CloudFlare, I would have to hire a dedicated resource to manage all this for me."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"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."
"The solution provides good load balancing and protection against DDoS attacks."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"I like Cloudflare's application gateway and DDoS protection."
"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."
"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."
"The most valuable part is the analytics and visualization."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"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."
"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."
 

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)."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"More insight into analytics and threats would be a good place to start improving Cloudflare."
"At the end, it is worth than giving your house keys to the NSA."
"Yes, there were a few times when some of their CDN nodes would fail, creating serious speed issues with the site without any warning or notification from their side."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"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."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"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 give the price a five out of ten."
"The product's pricing is cheap."
"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."
"A free version of the solution is available."
"There are no additional costs beyond the standard licensing fees."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We don't have any issues with the price."
"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."
