Executive SummaryUpdated on Jan 1, 2025

Imperva Web Application Firewall and Azure Front Door compete in the web security and content delivery network category. Imperva seems to have the upper hand with its comprehensive security features despite challenges in UI, while Azure Front Door is favored for global application deployment and user-friendly configuration but faces some limitations in load balancing.

Features: Imperva Web Application Firewall offers threat radar for detecting potential attacks, seamless integration with existing systems, and robust DDoS protection. On the other hand, Azure Front Door provides extensive CDN capabilities, effective bot protection to prevent automated cyber threats, and efficient load balancing, making it particularly appealing for managing traffic across multiple regions.

Room for Improvement: Users of Imperva indicate that policy management could be streamlined, the complex UI can be confusing, and there are concerns about false positives. Azure Front Door users suggest enhancing global load balancing capabilities and providing better clarification of product functionalities, as some features may not be intuitive for all users.

Ease of Deployment and Customer Service: Imperva offers versatility with both on-premises and cloud deployments but some users find the complexity challenging. Its technical support receives praise, though delays occur at times. Azure Front Door is primarily cloud-based, making its deployment relatively straightforward, though it might require additional localized support due to certain technical issues.

Pricing and ROI: Imperva is perceived as expensive but offers substantial ROI, particularly in sectors like banking. Its hybrid environment support allows for variable pricing based on selected protection levels. Azure Front Door provides a pay-as-you-go model with flexible tiers, which can become costly if premium features are selected, but users value the competitive balance of features and pricing.

Featured Reviews

Spencer Malmad

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.

Thomas Zebar

Azure Principal Architect at Cloud Computech Consultancy

Provides great security with a good application firewall

The initial setup is straightforward. If you want to use the portal, CLI, or PowerShare, or you want to use automation data for one month, it's straightforward. Even when it comes to operational maintenance, it's pretty easy and straightforward. Microsoft has done a great job on that front. Maintenance generally requires someone who is a cloud administrator or similar to maintain services in general, with Front Door a small piece of a larger maintenance requirement. There's not a lot to manage, the configuration is simple. I encourage people to document the configuration and infrastructure as well as disaster recovery in case anything happens.

Abdullah Jin

Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees

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 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."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."

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

"The DDoS protection is the most valuable aspect of the solution."

"The tool is user-friendly."

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

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

More Cloudflare pros

"I find the technical support excellent, and I rate it a ten."

"The tool is easy to use for beginners."

"Rules Engine is a valuable feature."

"Azure Front Door provides DDoS protection and features related to WAF."

"I am impressed with the tool's integrations."

"Azure Front Door provides DDoS protection and features related to WAF."

"The price is one of the most important aspects of the product. It's quite affordable."

"It inspects the traffic at the network level before it comes into Azure. We can do SSL offloading, and it can detect abnormalities before the traffic comes into the application. It can be used globally and is easy to set up. It is also quite stable and scalable."

More Azure Front Door pros

"It works right out of the box once you integrate the application."

"The compliance is the most valuable aspect."

"Imperva is easy to use and deploy. The UI is excellent."

"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 has been quite stable. I have not seen any bugs at all."

"Data masking is the most valuable feature of this solution."

"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."

"Protection is the best solution since it has profile functionality."

More Imperva Web Application Firewall pros

Cons

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."

"Technical support is lacking."

"There should be a specific price list for enterprise-level customers."

"The solution could be more user-friendly."

"An integrated SSO feature would be useful for Cloudflare DNS."

"The product support needs to be accessible from more places, a wider area of coverage."

"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."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

More Cloudflare cons

"I dislike the URL set parameters."

"There is room for improvement and they're working on it."

"It lacks sufficient functionality."

"In the tool, there needs to be a good amount of monitoring in the area of health probes to capture in front of what is happening."

"This is a relatively expensive solution."

"The product's features are limited compared to Cloudflare. The tool also doesn't work well in a hybrid environment. I would like to see a way to add personalized APIs in the system."

"The user interface needs improvement as it is difficult to create the mapping to link the problem with your private address sources."

"There's a limitation on the amount of global rules we can add."

More Azure Front Door cons

"It would be helpful to have a "recommended deployment", or even a list of basic features that should either be used or turned on by default."

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

"Support is one thing I wish Imperva could improve."

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

"Imperva Web Application Firewall can improve by providing better features, such as improved prevention of zero-day attacks. Additionally, it should include a VR meta-analysis."

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

"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."

"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."

More Imperva Web Application Firewall cons

Pricing and Cost Advice

"We don't have any issues with the price."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"The price of the solution is expensive."

"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."

"I give the price a five out of ten."

"A free version of the solution is available."

"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."

"The cost primarily depends on the size of the organization."

More Cloudflare pricing and cost advice

"The solution is a bit expensive."

"The transition to the premium tier has led to increased costs, making it more expensive than the classic tier."

"The product is expensive."

"It is on a pay-as-you-go basis."

"The pricing of the solution is good."

"Considering the standard licensing of the tool, even though we have not checked the billing as of now, it might not be very costly."

"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."

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

"Imperva Web Application Firewall is expensive."

"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."

"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."

"The tool is expensive."

"Imperva Web Application Firewall's pricing is expensive."

"It is a very affordable solution."

Cloudflare is a highly-regarded Content Delivery Network (CDN) and a Distributed Denial-of-Service (DDoS) protection solution. 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. Using Cloudflare, businesses, educational entities, NGOs, vloggers, bloggers, and anyone else with an internet presence can experience more secure, faster websites and applications.

Currently, there are millions of Internet locations on Cloudflare, and the Cloudflare network
continues to grow every day by the thousands. The solution is able to fulfill the requests for
millions of websites seamlessly and serves on average 45 million HTTP requests per second.

Cloudflare has safe, secure data centers in close to 300 cities worldwide to ensure every
client request is filled as quickly as possible. It is Cloudflare’s edge network that makes this
possible by keeping content and other services as close to each client as possible, so the
information requests are always only seconds away.

Many organizations that work in democracy, civil society, human rights, or the arts are able to
access Cloudflare's highest levels of protection for free via Project Galileo. Additionally, official
election websites can be secured from hacking and fraud through Cloudflare’s Project
Athenian, also at no additional cost.

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
