Executive SummaryUpdated on Dec 21, 2025

Imperva Application Security Platform and AWS Shield both compete in the cybersecurity sector, specifically offering protection against web-based threats. Imperva appears to have the upper hand due to its extensive feature set and integration options, catering more comprehensively to security needs.

Features: Imperva offers features such as a Web Application Firewall (WAF), DDoS protection, real-time traffic analysis, and security intelligence. It provides extensive customization and integration capabilities. AWS Shield is valued for its ease of use and effective DDoS protection, making it simple to deploy in cloud environments. While useful, AWS lacks some of the advanced security features provided by Imperva.

Room for Improvement: Users recommend that Imperva enhance customer support, reporting features, and traffic analytics. There's also a call for more transparent licensing and UI improvements. AWS Shield could improve dashboard visibility and should consider offering more advanced features from the Shield Advanced in the standard version. Both platforms could benefit from better threat reporting and customization options.

Ease of Deployment and Customer Service: Imperva offers various deployment options, including cloud and on-premises solutions, though on-premises setups can be complex. AWS Shield is praised for its straightforward integration within AWS environments. While customer service is generally positive for both platforms, Imperva's support receives mixed reviews on responsiveness, whereas AWS Shield is appreciated for reliable support and resource availability.

Pricing and ROI: Imperva is seen as more expensive, but its comprehensive features justify its cost, offering strong ROI in high-risk environments. Its pricing is flexible but potentially high for added features. AWS Shield offers a straightforward, scalable pricing model, especially beneficial for organizations deeply integrated within AWS. However, costs for advanced features can accumulate rapidly.

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.

Solution ensures website availability and proactive threat mitigation

Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.

Quotes from Members

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

Pros

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

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

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

"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."

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

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

More AWS Shield pros

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

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

"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."

"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."

"I like the user-friendly interface."

"The solution's most valuable aspect is that it is easy to configure."

"The solution is very good at intercepting traffic before it gets to our data centers."

"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."

More Imperva Application Security Platform pros

Cons

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

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

"The network has been experiencing frustrating performance issues today, which is not typical for Nigeria."

"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."

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

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

More AWS Shield cons

"One potential improvement for Imperva is enhancing its alert system."

"Their portal is very limited and needs improvement."

"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."

"Imperva DDoS does not provide version control."

"We faced issues regarding compliance with client procedures. The client had strict compliance rules, and Imperva needed to be on a VM, while the client required containerization, causing a conflict. They went with Imperva for the on-premise version but shelved the cloud project due to too many blockers."

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

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

"The rules surrounding the making of web applications could be improved."

More Imperva Application Security Platform cons

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."

"Varies depending on the needs of the customer."

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

"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."

"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."

"The data packages are higher than our needs so we end up paying for data that we don't use."

"It is a very affordable solution."

"The tool is expensive."

"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
