Executive SummaryUpdated on Jan 1, 2025

Imperva Web Application Firewall and Radware Cloud WAF Service compete in the web application security market. Imperva seems to have the upper hand due to its comprehensive feature set and high ROI despite its pricing.

Features: Imperva Web Application Firewall provides DDoS prevention, bot protection, and advanced application security. Its dynamic profiling, signature-based policies, and AI-driven security measures are highly valued. Radware Cloud WAF Service is noted for its DDoS and bot mitigation along with intuitive analytics and CDN features that enhance performance.

Room for Improvement: Imperva faces challenges with GUI complexity, policy management, and integration limitations. Users seek improvements in visibility, automation, and cost. Radware requires better API documentation, integration, and reporting. Users have indicated the need for enhanced customer education resources and certificate management.

Ease of Deployment and Customer Service: Imperva offers deployment flexibility across on-premises, cloud, and hybrid configurations, though support is quicker for cloud setups. Radware performs well in cloud deployment with scalable options, but customer service efficiency and integration with third-party tools could be improved. Both solutions provide effective technical support.

Pricing and ROI: Imperva's pricing is considered expensive, especially for SMBs and markets outside the US, but offers high ROI due to its robust security options. Radware's pricing is competitive, particularly with bundled options, offering API protection and bot management services, and is generally regarded as favorable.

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.

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.

Assistant Manager (Network and Cyber Security) at a manufacturing company with 1,001-5,000 employees

Consistently protect applications with advanced threat detection and active support

We have had a very good experience with Radware Cloud. It has significantly reduced attacks on our applications. All our critical applications are onboarded to Radware, which uses AI to automatically learn behavior patterns and refine security policies. It also provides comprehensive protection against the top ten web application security risks. Importantly, we have not experienced any zero-day attacks because Radware Cloud offers protection against emerging threats. The Emergency Response Team is very active, and I consistently receive excellent responses from them. It's a very comprehensive and user-friendly solution. It's easy to implement and integrate. We also have found it's easy to reach support if we need help. The solution has helped us enhance our cyber security posture. It's good for data protection. We've been able to protect our public-facing infrastructure. We haven't had any incidents or compromises in the entire three years we've used Radware. The Cloud WAF Service blocks unknown threats and attacks effectively. The analytics are very good. The API discovery feature is very helpful, and end-to-end API protection is useful. Everything is encrypted to ensure effective protection. We get Layer 7 protection from it. The API discovery is a very useful feature. It is easy to use. A few months before, I did a demo to learn more. We can see which APIs are being used or not. It helps us discover and remove unused APIs. In our case, we found 20 APIs that were not used by the team. We use the CDN features. It's pretty easy to use the combination of CDN and Cloud WAF. It helps your Radware Cloud connect with the nearest server or the Redware server. We have multiple servers worldwide, so this is useful for us. Integration is very easy. Sometimes, we have 10 to 15 applications hosted on the cloud. It's very easy to add applications. It's not complicated. From the Radware cloud, it's integrated with our SOC. All the logs are received by the SOC.

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."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"Generally, I am satisfied with this product."

"It's very user-friendly."

"It is a fast and secure DNS."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

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

More Cloudflare pros

"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 scalable."

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

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

"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"

"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."

"There are a number of features that are valuable such as the account takeover and various antivirus features."

"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."

More Imperva Web Application Firewall pros

"The solution requires very little maintenance; we install it, it works without any problems, is reliable, and we can almost forget about it."

"From a financial point of view, we no longer need to appropriate more horsepower to our backend web servers constantly to service these requests because Cloud WAF is preventing malicious bots from accessing our web page. It reduced the load on our backend."

"I highly recommend Radware Cloud WAF for its reliability and fast support."

"The most valuable feature is the monitoring dashboard that we access through the portal."

"The most important aspect of Radware Cloud WAF is that it is over the cloud, offering a comprehensive solution that includes WAF, API protection, bots, and Layer 7 DDoS."

"Radware Cloud WAF Service ensures our systems are stable, running smoothly, and blocking all attacks effectively."

"Importantly, we have not experienced any zero-day attacks because Radware Cloud offers protection against emerging threats."

"I particularly appreciate the low administrative burden of this solution, as well as the excellent monitoring tools."

More Radware Cloud WAF Service pros

Cons

"The solution could work at being less expensive. It costs a lot to use it."

"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."

"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."

"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."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

"Latencies are always a problem."

"Integration involving API with other products could be more user-friendly."

"DNS Management."

More Cloudflare cons

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

"The solution works for particular zones but isn't always the best solution for all zones."

"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."

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

"I would like to improve the tool's turnaround time in terms of support."

"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."

"One potential improvement for Imperva is enhancing its alert system."

"There could be some limitations that from the converged infrastructure perspective: when you want to converge with everything and you want Imperva to get there easily because it's not a cloud component. For example, when you want to build servers and you're using OneView to manage your software-defined networks, implementing Imperva right away is not that simple. But if you're doing just a simple cloud infrastructure with servers in there, you're good to go. Also, we are not able, with Imperva, to block by signatures. Imperva by itself needs to be complemented with another service to do URL filtering."

More Imperva Web Application Firewall cons

"We receive many reports from our security team of IPs flagged by our security tools, such as Palo Alto. I cannot add the file containing the IPs to get them blocked; instead, I have to contact Radware support and open a ticket for them to do it. I need to be able to block flagged IPs myself, as it currently takes more time to open a ticket, contact the support team, and wait four to six hours for a response. I want to be able to upload a file with 2,000-3,000 IPs in the console and then apply and save the configuration."

"The integration part could be better."

"The connection between the front and back ends could be improved."

"Our only complaint is the reporting on the DDoS side. We also use Radware for on-premises DDoS protection and their Vision product. I just want to give paint you an example. We face so many Layer 3 and Layer 4 DDoS attacks on Cloud WAF. The reporting on those types of attacks can be improved."

"They have a portal for webinar training but because we are in a Spanish-speaking country, it is difficult for us to watch them. Not all of us are fluent in English, but most of the courses and webinars are in English. That part could be improved..."

"The primary area for improvement is in issue detection and understanding whether a log is a false positive. It can sometimes be a challenge to take the data of a given security event and determine if it's a genuine threat using a Wiki etc."

"Radware does not have much online training available to help customers get the most out of this solution."

"An area of improvement is the visibility at the attack level."

More Radware Cloud WAF Service cons

Pricing and Cost Advice

"The product's pricing is cheap."

"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."

"The price is reasonable."

"The product's pricing is minimal compared to other products."

"The price of the solution is expensive."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

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

"We are using the free version."

More Cloudflare pricing and cost advice

"There is a license for this solution and we purchase the license annually with no additional fees."

"The price of this solution is a little bit high compared to competitors."

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

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

"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."

"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."

"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."

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

More Imperva Web Application Firewall pricing and cost advice

"I believe the prices are fair."

"If you plan to deploy Cloud WAF, keep in mind that the product is priced based on the megabits of traffic that pass through and the number of transactions. You should get your requirements correct up front. The active attackers feed and CDN services cost extra, so you need to negotiate these features upfront."

"The pricing is fair. We compared Radware to others using industry reviews and Radware is at the top right now."

"The price is a bulk average."

"Radware Cloud WAF Service falls within a mid-range price bracket compared to other web application firewall solutions."

"The pricing is fair; it's neither particularly cheap nor expensive."

"We are based in El Salvador and don't have a direct license with Radware; we purchase the license through resellers. The pricing is reasonable, as I managed an Akamai product in a previous position, and Cloud WAF is competitively priced."

"When compared to Akamai and F5, Radware's pricing and licensing are highly competitive."

Overview

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

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
