Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
David Shlingbaum - PeerSpot reviewer
Simple solution and good WAF
Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section. Users get errors or EBAs, and if they want to read about it, they need to find it in the help section of the site. It would be more helpful to allow users to see more information and tips immediately from within the alert.

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."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"It is a fast and secure DNS."
"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."
"The DDoS protection is the most valuable aspect of the solution."
"I rate its stability a ten out of ten."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"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."
"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."
"The initial setup was very easy."
 

Cons

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"The product support needs to be accessible from more places, a wider area of coverage."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"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."
"DNS Management."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"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."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"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."
"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 solution is expensive when compared to other products but offers unlimited bandwidth."
"The product's pricing is cheap."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We are using the free tier of the solution."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"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."
