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

"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"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."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"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."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"The initial setup was very easy."
"The most valuable part is the analytics and visualization."
 

Cons

"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"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."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"There are some issues with the CDN services."
"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."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"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."
"In terms of improvement, the cost factor is always there."
"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."
"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."
 

Pricing and Cost Advice

"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 price is reasonable."
"The tool is a premium product, so it is very expensive."
"We are using the free tier of the solution."
"A free version of the solution is available."
"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."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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 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."
"I’d simply say it’s really worth it."
"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."
