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

"Smaller businesses have seen great ROI due to the low investment and strong performance."
"It is very clear and the information is very useful."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Cloudflare has many features."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."
"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."
"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."
"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."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
 

Cons

"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"More insight into analytics and threats would be a good place to start improving Cloudflare."
"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."
"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."
"I have found CloudFlare's support to be unresponsive at times, and not very helpful with providing technical details for issues that we have reported over the years."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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 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."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"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."
"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

"The tool is a premium product, so it is very expensive."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is cheap."
"I give the price a five out of ten."
"We don't have any issues with the price."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"We are using the free tier of the solution."
"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."
"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."
