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.

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

"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."

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

"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."

"The product is easy to use."

"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."

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

More AWS Shield pros

"We use Imperva DDoS to stop DDoS attacks and reduce the amount of unwanted queries against web services or web scraping."

"The solution is very scalable; it is one of the most important features, and you can also expand resources and features as well."

"Our ROI is about 45% since deployment on reduction of our cloud bill."

"There are some features that are configured by default, so even without doing much, it can still provide a level of protection."

"In my opinion, Imperva Incapsula is not expensive compared to the other similar solutions in this category."

"The user-generated spam stopped after we started using Incapsula, and so we feel more secure."

"The availability of our sites, thanks to the load balance functionality, has improved, and it enables the site to be available all the time, despite people trying to attack it."

"It has helped a lot with working among, and creating a link between, different teams in my organization, of course I’m referring to security, networking and system application teams."

More Imperva Application Security Platform pros

Cons

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

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

"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."

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

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

"The product is expensive."

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

More AWS Shield cons

"Another area that could do with improvement is certificate management. I do not like the way that Incapsula handles certificates very much."

"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."

"No major improvements are required, but it should still work on reducing the false positives."

"We had an issue when securing the web applications for DDoS protection."

"On the negative side, API security mainly supports cloud-based solutions, while most of my customers prefer on-prem setups, so achieving high performance with on-prem solutions would be beneficial."

"Pricing is a challenge for most of our customers."

"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."

"The hardware being more expensive compared to other vendors poses a challenge, along with a need for improvement in the cloud WAF offerings."

More Imperva Application Security Platform cons

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."

"The tool is cheap."

"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."

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

"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."

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

"The solution's price is high for small companies."

"The solution's pricing is an issue."

"It's an excellent product, but it can be very costly."

"It is expensive."

"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."

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