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.

reviewer2818155

Senior Associate at a tech vendor with 10,001+ employees

Application protection has improved and reporting and dashboards still need refinement

I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Quotes from Members

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

Pros

"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."

"The API gives us the ability to remote control our DNS settings."

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

"It's very user-friendly."

"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."

"I have used it to bring enterprise-grade features to my small business clients at low or no cost."

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

More Cloudflare pros

"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."

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

"It is quite scalable, and we have not faced any issues with its scalability."

"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."

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

"The product is easy to use."

"AWS Shield offers numerous protection features that are crucial at the application layer, safeguarding users from distributed denial of service attacks, man-in-the-middle assaults, and hacker orchestrations."

"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."

More AWS Shield pros

"The solution offers good security against a variety of web attacks, and the protection from DDoS attacks is very useful."

"I was involved in the deployment and found that all the features in this product are fantastic, especially the correlated attack validation, threat radar (reputation, fraud), and virtual patching."

"Basic setup is simple but, as with any caching/WAF setup, there are tricks you need to learn, but it works really nice out of the box!"

"On the activity log, I can see the exact details, the visit, and the threat."

"Hands down, the WAF is the most valuable feature; being able to identify, block, whitelist or blacklist as needed, are all valuable."

"Imperva anti-DDoS protection has the well-known value of having lots of distributed nodes around the world, making it the best value for DDoS protection."

"Imperva Application Security Platform has positively impacted my organization by providing strong protection for web applications, as many big companies in the UK use Imperva WAF as an essential protection layer, illustrating its effectiveness."

"Imperva Incapsula WAF is an awesome solution for implementing a WAF with good support and reliable hardware performance."

More Imperva Application Security Platform pros

Cons

"More insight into analytics and threats would be a good place to start improving Cloudflare."

"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."

"If they improve on the placement of their data centers, it would be better."

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

"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."

"Technical support is lacking."

More Cloudflare cons

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

"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."

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

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

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

"Perhaps the time required to detect anomalies can be reduced."

"The time taken to detect anomalies must be reduced."

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

More AWS Shield cons

"I think that better bot protection is needed in this solution."

"It would be nice to have a mobile app as a dashboard interface instead of the web administration, but the service is really great."

"One improvement I would like to see in Imperva Application Security Platform is the ability to fail over to different sites for my same application."

"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."

"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."

"We rate technical support as really bad."

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

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

More Imperva Application Security Platform cons

Pricing and Cost Advice

"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."

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

"The product's pricing is cheap."

"A free version of the solution is available."

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

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

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

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

More Cloudflare pricing and cost advice

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

"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 tool's pricing is good."

"The tool is cheap."

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

"The cost is on par with other solutions such as Cloudflare and Akamai."

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

"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."

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

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

"The license is on a yearly basis."

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

"There is a license or subscription renewal that our customers pay."
