Owner at Tech Exchange

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.

Quotes from Members

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

Pros

"The solution provides good load balancing and protection against DDoS attacks."

"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."

"The solution offers the flexibility to control configuration rules."

"The most valuable feature is the web application firewall."

"The most valuable features of the solution are performance and security."

"It is a fast and secure DNS."

"The solution is stable, and the DNS servers are simple to use."

"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."

More Cloudflare pros

"The product's bot protection feature is valuable for our company."

"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."

"It provides an ease of policy management."

"The solution can be used for threat prevention or as a cloud-to-cloud backup system"

"I like its ability to identify known attacks, including DDOS attacks. It's valuable because software must be able to stop known attacks. Application attacks are evolving all the time. When it comes to software-as-a-service, we need to have software that knows about all the latest attacks. It should also protect against major unknown attacks."

"It mitigates all of the availabilities of risks around web applications."

"Learning mode and custom policies are helpful features."

"The solution is cloud-based and offers us good uptime. It has combined web and API security. Therefore, with one license, you access both application security and also API security."

"I am impressed with the product's scalability, availability, easy management, and security. We were able to integrate the product with Azure and Sentinel."

"The solution integrates seamlessly with other tools and has a good alert mechanism."

"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."

"Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."

"The solution is stable."

More Imperva Web Application Firewall pros

Cons

"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."

"Latencies are always a problem."

"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."

"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

"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."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"Cloudflare should add more documentation and pricing to the cloud version."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

More Cloudflare cons

"It's a very specific solution that is only requested for a customer's web code or their global IT policy."

"The stability of the product is an area of concern where improvements are required."

"One significant area for improvement in Barracuda WAF-as-a-Service lies in its market positioning and pricing strategy."

"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."

"We found it a bit slow when accessing it through the web browser. The URL also exposed the user name and the hashed password. When I log into my Barracuda WAF user portal, I could see the username and the hashed password on the URL itself. So, it is not very secure, and it is important to take that off."

"I would like the solution to improve its support response time."

"I don't really use it and therefore can't speak to areas of improvement."

"The process to upgrade from one version to another can be a lot simpler than it is currently."

"Sometimes, support tickets don't get addressed quickly."

"The support for the on-premises version needs improvement."

"There is nothing specific where the application firewall is falling short."

"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."

"It is complicated to integrate the solution's on-cloud version with other platforms."

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."

"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."

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."

"We are using the free tier of the solution."

"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."

"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."

"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."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

More Cloudflare pricing and cost advice

"The product is expensive but it offers flexible pricing. It could be affordable."

"It's very difficult for me to give an estimate of the cost. All I know is that we sell the box itself as a service."

"I rate the product's price a five on a scale of one to ten, where one is low, and ten is high. There are no additional costs to be paid apart from the standard licensing fees attached to the solution."

"It's an excellent product, but it can be very costly."

"Imperva Web Application Firewall is expensive."

"There are a couple of different licensing models."

"The price of Imperva Web Application Firewalls is expensive compared to others."

"The solution's pricing is an issue."

"The tool is expensive."

"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."

"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."

The robust global connectivity cloud platform that is Cloudflare ensures users are able to connect to the Internet quickly, securely, and reliably. Cloudflare is one of the world's largest networks in the marketplace today.

Reviews from real users

“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. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“The most valuable feature of Cloudflare is the GUI. You are able to control the solution very
well through the interface. There is a lot of functionality that is embedded in the service.” PeerSpot user, Competence Center Manager at a tech services company
