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

"The technical support on offer is excellent; they are very helpful and responsive, and we are quite happy with the level of service they provide to their customers."

"Generally, I am satisfied with this product."

"The UI is good."

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."

"The most valuable features of the solution are performance and security."

"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."

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

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

More Cloudflare pros

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

"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."

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

"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."

"The product is easy to use."

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

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

More AWS Shield pros

"The solution has a very good interface."

"It's worth it. It's a fine solution for medium/big companies worried about attacks that happen in the wild."

"The configurability of the tools and the ease of operation to be the most valuable feature of Imperva."

"The solution is stable."

"The Imperva Web Application Firewall feature I have found the most valuable is the ease of deployment."

"By using this application, the firewall is blocking every suspicious activity and event, and now we are safe with peace of mind that nobody will use malware on us or try to hack our website."

"The solution can be configured in just a couple of minutes."

"Deployment is simple and very fast."

More Imperva Application Security Platform pros

Cons

"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."

"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."

"There are some issues with the CDN services."

"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."

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

"Technical support is lacking."

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

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

More Cloudflare cons

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

"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."

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

"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."

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

More AWS Shield cons

"HTML minification could be improved. The actual HTML minification does not provide the maximum HTML minification nor provides the best result."

"Although we're only using it for the accelerator part, the purging of files and the way this feature functions could use improvement."

"I would like to have support for SSL management and secure DNS."

"The log analytics interface within Incapsula isn't really good. For example, if you have to get all logs from there, it's a very cumbersome process."

"The process to upgrade from one version to another can be a lot simpler than it is currently."

"I think the pricing needs some tweaks."

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

"Imperva Application Security Platform could be improved if it allowed integration with Active Directory in the cloud, or if it provided visibility of user roles and permissions."

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."

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

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

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

"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."

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

"A free version of the solution is available."

"We are using the free tier of the solution."

More Cloudflare pricing and cost advice

"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."

"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."

"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 tool is expensive."

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

"There are a couple of different licensing models."

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

"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."

"Imperva Web Application Firewall is expensive."
