Executive SummaryUpdated on Mar 22, 2026

Imperva and AWS Shield both offer advanced solutions in application security, specifically targeting DDoS protection and web application vulnerabilities. Imperva appears to have a broader set of features, particularly in API security and profiling features, giving it a slight edge in comprehensiveness.

Features: Imperva provides robust features for application security, including advanced DDoS protection, API security, and a flexible deployment model. It's known for ease of use and custom policy profiling. AWS Shield integrates seamlessly with AWS services, offering real-time attack detection, advanced threat intelligence, and a strong focus on DDoS prevention, especially effective for cloud environments.

Room for Improvement: Imperva users point out the need for a more user-friendly GUI, improved policy rule sets, and quicker support response times. AWS Shield's health checks and anomaly detection require enhancements, particularly under complex attack scenarios. It also has limited built-in WAF features, needing AWS WAF for layer 7 protection, which adds to costs.

Ease of Deployment and Customer Service: Imperva supports diverse deployment models like on-premises and cloud-based environments. While customer service is generally positive, response times can be an issue. AWS Shield offers simple public cloud deployment, but some users face challenges in accessing complex support services, affecting responsiveness.

Pricing and ROI: Imperva's pricing is on the higher side with a complex model across various features, leading to a significant investment. However, the ROI is seen as high in sectors like banking. AWS Shield provides a scalable usage-based pricing model but incurs additional costs for AWS WAF. Its basic services are more affordable, yet comprehensive protection requires investing in Shield Advanced.

Advanced protection has secured critical web workloads and provides clear traffic visibility

From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Lead Architect at a comms service provider with 1,001-5,000 employees

Has enabled multi-layered threat mitigation but still lacks deeper visibility for advanced application attacks

AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods. It does not provide inherent protection against more sophisticated layer 7 attacks such as HTTP floods. In such cases, integration with WAF is necessary, which results in additional costs for customers. To protect layer 7, layer 4, and layer 3, customers must implement both solutions. The service also has difficulties with static detection thresholds, which may not be sensitive enough to detect smaller application-specific attacks. While AWS Shield is a key security service, AWS should enhance their expert support with 24/7 response for complex attacks, which is currently limited.

Stephen Tanimowo

Senior Cybersecurity Consultant at Cyberoutcome Limited

Strong policies and bot defenses have secured critical APIs and have reduced attack noise

From my research regarding the IAM space that Imperva Application Security Platform is trying to look into, I believe they still need to do a lot of modeling and modification to make sure that also helps. There are several competitors in the IAM space, so Imperva would do well if they can do some basic modeling and modifications from my own personal research and my own experience in the IAM space. Alternatively, they could actually just focus on trying to be stronger in the web application space and the database activity monitoring space.The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum. There are times when clients could have urgent issues to attend to. The support team could do more by having a faster response rate.

Quotes from Members

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

Pros

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

"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."

"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."

"Smaller businesses have seen great ROI due to the low investment and strong performance."

"New and innovative way to protect the client's data."

"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."

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

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

More Cloudflare pros

"I recommend AWS Shield because it has proven helpful in tracking DDoS attacks within both my past and present environments, and without AWS Shield, a business could face potential losses, as this tool helps in identifying and mitigating fake traffic that disrupts applications, ultimately supporting business continuity."

"If most of your internet presence from your application side is in AWS, AWS Shield is a great option."

"The product is easy to use."

"The product has a good mechanism to analyze trends and trigger events."

"AWS Shield is aligned with the web application firewall (WAF), and they work seamlessly together, primarily working with Elastic Load Balancer, CloudFront, and Route 53 for CDN and DNS services protection."

"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."

"I am impressed with the product's multiple features like security."

"It is integrated with AWS. So, it gives you a good first step."

More AWS Shield pros

"My advice to anyone considering Imperva Web Application Firewall is that they can safely go to this environment without having a second thought."

"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."

"Compared to other web application firewalls in the market, Imperva does things in the most accurate way."

"The most valuable features for us are the DDoS and Bot."

"The most valuable features of the Imperva Web Application Firewall are performance and flexibility. We can extend or customize the box itself."

"I see valuable benefits from advanced detection and traffic profiling during DDoS attacks, and I track some metrics related to DDoS protection performance."

"The most valuable aspect of it is that it blocks all types of attacks."

"After moving to Imperva Application Security Platform, these attacks have been prevented significantly, and the attacks on the initial level have been considerably reduced."

More Imperva Application Security Platform 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."

"It looks like they don't support as many TLDs as other registrars, but since they are very new as a registrar, I expect this may improve soon."

"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."

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

"The solution could use more analytics on the backend to give us more insights into everything."

"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."

More Cloudflare cons

"The product is expensive."

"The product needs to improve its logs and reports to make it read better."

"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it."

"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."

"We end up having to pay extra for features that AWS adds that we don't need."

"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."

"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."

"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."

More AWS Shield cons

"There’s nothing that’s missing in terms of features."

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

"Management of policies and rules can be complicated and the physical setup of the product has implications on HA."

"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."

"I would like to see automated reporting to improve visibility."

"Licensing should be improved. Most of the clients aren't happy. It's expensive."

"It needs to be improved every time there are new attacks."

"Customer Service: Average to poor. Technical Support: Average to poor."

Pricing and Cost Advice

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

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

"There are no additional costs beyond the standard licensing fees."

"That is one of the great features. I was able to access the majority of the features and services for free."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"A free version of the solution is available."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"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."

More Cloudflare pricing and cost advice

"The tool's pricing is good."

"We pay $3000 per month for the solution."

"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."

"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."

"The tool is cheap."

"The price is high compared to other solutions like FortiWeb."

"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."

"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."

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

"Everybody complains about the price of this solution."

"The license is on a yearly basis."

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

"It is not expensive compared to the other similar solutions in this category."
