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.

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.

Tanuj-Garg

CIO at a computer software company with 501-1,000 employees

API discovery, bot defense, and DDoS capability optimize application security and development

I see areas in Radware Cloud WAF Service for improvement, specifically in its initial tuning period, because the machine learning model takes two to three weeks for baseline behavior establishment. Closely monitoring alerts during this period is essential to avoid false positives. There's an alert noise issue; during the early stages, we received a high volume of alerts for minor issues, requiring collaboration with the SOC team to fine-tune thresholds and concentrate on genuine threats. The documentation is not up to par, as while the platform's system is robust, the documentation, particularly for API integration, could be more developer-friendly with real-world use cases.

Quotes from Members

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

Pros

"The solution is very good at mitigating threats."

"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."

"Easier http to https redirect using page rules"

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

"It is a fast and secure DNS."

"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 most valuable feature is the web application firewall."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

More Cloudflare pros

"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."

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

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

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

"The solution is stable."

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

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

More Imperva Web Application Firewall pros

"DDoS protection is a valuable feature that works efficiently."

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

"My experience with the technical support of Radware Cloud WAF Service is that they are excellent, and I have established a strong relationship with the executive leadership up to Roy, the CEO."

"The isolation feature is the most important one because everything is going directly to Radware first and then it goes into our system. What we get is the filtered version of everything that would otherwise come directly to us."

"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 has several valuable features, with good support and a user-friendly GUI."

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

"I highly recommend this product to others because I'm satisfied with the mitigation and proactive protection."

More Radware Cloud WAF Service pros

Cons

"The documentation could improve for Cloudflare DNS."

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."

"Latencies are always a problem."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."

"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."

"The product needs to improve its automation."

More Cloudflare cons

"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."

"I'd like the option to pick your bot protection."

"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."

"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."

"There's always room for improvement. Occasionally, there might be false-positive alerts."

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

"Imperva Web Application Firewall is very expensive."

"The signature updates could be faster. Sometimes we have to upload signatures to the Imperva portal for checking and analysis before we can use them."

More Imperva Web Application Firewall cons

"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."

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

"The initial setup was complex and took a long time to complete."

"The Cloud Portal has room for improvement."

"Radware's bot manager can be improved because it's very complicated to implement for apps. Radware could also add alerts by WhatsApp or Telegram. It only sends notifications via email or SMS."

"The lower-level technical team at Radware could improve their approach to problem-solving as they sometimes are very slow."

"They've changed their process for call logging. I suppose it's fine, but I used to be able to send emails in. They could also build up more local resiliency here in South Africa. They're working on that, so it isn't much of an issue now."

"The integration part could be better."

More Radware Cloud WAF Service cons

Pricing and Cost Advice

"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."

"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 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 tool is a premium product, so it is very expensive."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"A free version of the solution is available."

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

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

More Cloudflare pricing and cost advice

"The cost of this solution depends on the platform."

"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."

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

"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."

"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."

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

"There are a couple of different licensing models."

"Imperva Web Application Firewall is expensive."

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; it's neither particularly cheap nor expensive."

"For the current market, the price for Radware Cloud WAF Service is exactly where we want it to be."

"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."

"The pricing is fair."

"I am not directly involved in pricing and setup cost discussions, but it seems that Radware offers a more cost-effective solution compared to F5. It is considered a good value for our budget."

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

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
