It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Straightforward setup with very good granularity and performance
Our company uses the solution as a data center firewall.  It is hard to determine all users within our infrastructure. It depends on systems we put behind the solution. Its internal but also a data center firewall. Sometimes, there are hooks from the solution to our external infrastructure or…

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

"Cloudflare has many features."
"The solution offers the flexibility to control configuration rules."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The technical support is good."
"The most valuable feature is its usability."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"It is a fast and secure DNS."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The solution is very straightforward. The usability is great."
"The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications."
"The product’s most valuable features are LTM and WAF."
"Its performance and ease of use are valuable."
"It blocks various attacks and mitigates disasters from occurring."
"CGNAT is one of its strong areas."
"F5 BIG-IP Advanced Firewall Manager's most valuable feature is load balance. It is readily available and uncomplicated."
"The protection is very useful."
"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 initial setup was very easy."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"The most valuable part is the analytics and visualization."
"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."
 

Cons

"DNS Management."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Technical support is lacking."
"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'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."
"There should be a specific price list for enterprise-level customers."
"An integrated SSO feature would be useful for Cloudflare DNS."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"F5 could provide a distributed cloud version."
"F5 BIG-IP AFM can improve the reporting interface in relation to advanced troubleshooting depending on CLI. They should have enhanced troubleshooting with the use of GUI."
"Deployment times vary according to the customer. It needs to be heavily configured. You need to look and you need to observe the behavior of the traffic before you can start configuring everything. It can take time."
"It doesn't compare to next generation firewalls"
"There should be simplified and better integration with BIG-IQ."
"The appliance and features could be enhanced further, especially in terms of security. Some features like the WAF firewall may seem expensive compared to the standard license, so there could be room for adjusting the pricing."
"The product is expensive."
"NGINX, which F5 purchased, has room for improvement in its features, particularly its load balancing or application load balancing features."
"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."
"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."
"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."
 

Pricing and Cost Advice

"We are using the free version."
"A free version of the solution is available."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The product's pricing is cheap."
"The price of the solution is expensive."
"The price is reasonable."
"There are no additional costs beyond the standard licensing fees."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"We need to pay a yearly licensing fee for the solution."
"It is somewhat on the expensive side although it is worth the additional cost."
"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."
"The product is expensive."
"The solution is slightly on the higher priced side."
"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."
"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."
