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

"The most valuable feature of Cloudflare DNS is security."
"The most valuable features of the solution are performance and security."
"Cloudflare has many features."
"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."
"I rate its stability a ten out of ten."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"New and innovative way to protect the client's data."
"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."
"The solution is stable."
"Very intuitive and granular configuration - It does not require much time, or advanced knowledge, for configuration and maintenance."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"Imperva has a complete picture of how the applications are utilizing it. It is handy. DDoS is good. It has an internally managed database. It is very easy to integrate. We have integrated it with SIEM services."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"Compared to other web application firewalls in the market, Imperva does things in the most accurate way."
"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 use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"Technical support is lacking."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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."
"There should be a specific price list for enterprise-level customers."
"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."
"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."
"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."
"The initial setup could be simplified. Every time you have to install the solution you have to get in touch with support or somebody that can to do that for you."
"The UI interface needs improvement."
"There's always room for improvement. Occasionally, there might be false-positive alerts."
"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."
"Sometimes our web application firewall will slow down."
"Their portal is very limited and needs improvement."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"We are using the free version."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"We don't have any issues with the price."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
