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.

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.

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

"Because our website is blazing fast it improves our conversion rates."

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

"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."

"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."

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

"We're partners with Cloudflare; this solution is the best product and it does not charge you for any kind of attack on your traffic, only for good traffic, and it can mitigate up to 30 TBPS of DDoS attacks."

"The technical support is good."

"Easier http to https redirect using page rules"

More Cloudflare pros

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

"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."

"The solution's ease of use is the most valuable feature."

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

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

"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."

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

"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

"Incapsula can help to hide the real origin and provide access control over different pages, and it can protect the website from being attacked."

"The WAF itself has been very valuable to me because it has such a complete range of features. Another reason why I like it is because it also takes care of the total overview of the traffic over the network."

"Imperva Application Security Platform has helped reduce incidents, save time, and improve my organization's security posture with specific measurable outcomes and metrics."

"This product is a reliable defense from malicious attacks on a network environment."

"It has fewer false positives"

"Imperva Application Security Platform positively impacts us because we have a critical website, so by placing a WAF of Imperva's quality, it allows us to have visibility and granular control over the various attacks that can occur on the website."

"With acquisition of a license to use the product, we received the ability to standardize database scanning and data protection across the enterprise around one product."

"The valuable features of Imperva WAF include its effective security breach prevention through automatically updating rules."

More Imperva Application Security Platform pros

Cons

"At the end, it is worth than giving your house keys to the NSA."

"Yes, there were a few times when some of their CDN nodes would fail, creating serious speed issues with the site without any warning or notification from their side."

"There are some issues with the CDN services."

"There should at least be a read-only view of the data so that resellers can properly support the clients."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

"Honestly the product has not really improved the way of my organisation."

"The Always Online feature has room for improvement. It seems to work sometimes and not others even with the pro version."

"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."

More Cloudflare cons

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

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

"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."

"The product is expensive."

"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."

"The product should give users more flexibility to customize their security policies according to their requirements."

"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

"As such, I have not seen a return on investment."

"If they can bring in generative AI features, that would be useful."

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

"The signature updates could be faster."

"If I had the opportunity to recommend an enhancement to Imperva it would be to have more POP (Point of Presence) in East and West Africa, and in Central Africa as well."

"Imperva Web Application Firewall is very expensive."

"Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."

"Scalability-wise, it is not so scalable as the solution is quite straightforward."

More Imperva Application Security Platform cons

Pricing and Cost Advice

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

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

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

"We are using the free version."

"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."

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

"The price is reasonable."

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

More Cloudflare pricing and cost advice

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

"Everybody complains about the price of this solution."

"It is expensive."

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

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

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

"Imperva Web Application Firewall is expensive."

"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."
