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.

Offers bot protection and DDoS Protection and protects public-facing portals
Support is one thing I wish Imperva could improve. They follow the phone model and keep rotating you from one customer service person to another. The layer one support isn't very clear about the workings of the product. My feedback is primarily about Imperva Cloud, not on-premise. On-premise is a whole new story. Support is the issue for Imperva Cloud. It's also a bit pricey. It's a premium service and very expensive. The licensing model is not very straightforward. Every feature is priced separately, and to enjoy maximum protection, you'll have to spend a lot of money. The licensing model is a bit complex, and each feature is very pricey. For example, API security and web application protection are two separate license packages.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The most valuable features of the solution are performance and security."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The solution is very good at mitigating threats."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The solution offers the flexibility to control configuration rules."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"Very intuitive and granular configuration - It does not require much time, or advanced knowledge, for configuration and maintenance."
"Data masking is the most valuable feature of this solution."
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"We can prevent attacks or issues even before they happen."
"There are many features. There is ease of deployment. You can deploy the Imperva Web Application Firewall in two to three minutes. After that, you have to set the policies. For setting policies, you have toggle buttons. You can turn something on or off."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"There is a quick switch between any of the the nodes if something goes wrong, where there's a there's an attack against a specific area. The security setup is reasonably easy. It's not a problem to do setups and rules and integrations. And, yeah, just the the back end team is also very willing to insist if there's questions that that we cannot answer or with these questions that we do have"
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"The solution could be more user-friendly."
"Support response time could be improved."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"There might be helpful if there was some web application firewall feature."
"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."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"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."
"Their portal is very limited and needs improvement."
"One potential improvement for Imperva is enhancing its alert system."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"There is nothing specific where the application firewall is falling short."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"It is complicated to integrate the solution's on-cloud version with other platforms."
"If they can bring in generative AI features, that would be useful."
"It should be more user-friendly. Like other web solutions, it would be helpful to be able to easily do policy configuration and identification inside the application. Understanding the in-depth configuration of a policy is somewhat difficult for an engineer, and they can improve that."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We don't have any issues with the price."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The product's pricing is minimal compared to other products."
"The cost primarily depends on the size of the organization."
"The price is reasonable."
"Everybody complains about the price of this solution."
"Imperva Web Application Firewall is expensive."
"It is a very affordable solution."
"There is a license for this solution and we purchase the license annually with no additional fees."
"The tool is expensive."
"Imperva Web Application Firewall's pricing is expensive."
"The price is high compared to other solutions like FortiWeb."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
