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.

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.

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 solution is very good at mitigating threats."
"The solution provides good load balancing and protection against DDoS attacks."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"I like Cloudflare's application gateway and DDoS protection."
"It's very user-friendly."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"Easier http to https redirect using page rules"
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
More Cloudflare pros
"It is integrated with AWS. So, it gives you a good first step."
"The solution's ease of use is the most valuable feature."
"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."
"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."
"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."
"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."
"The product is easy to use."
More AWS Shield pros
"The technical support is excellent."
"IncapRules is one of the most valuable features, as you can create your own security and access control rules on top of your security policy. Using IncapRules we were able to easily block Layer 7 DDoS attacks several times."
"It has threat intelligence and we are using Incapsula. With threat intelligence, we can separate HTTP and HTTPS traffic. We can use Incapsula to send all the threat intelligence to the WAF."
"The three-second service level agreement is already better than the competition."
"The solution is cloud-based and offers us good uptime. It has combined web and API security. Therefore, with one license, you access both application security and also API security."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"On the activity log, I can see the exact details, the visit, and the threat."
"Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."
More Imperva Application Security Platform pros
 

Cons

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"There should be a specific price list for enterprise-level customers."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Cloudflare should add more documentation and pricing to the cloud version."
"The product support needs to be accessible from more places, a wider area of coverage."
"Cloudflare's console should be made more user-friendly."
"The product needs to improve its automation."
More Cloudflare cons
"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."
"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."
"Perhaps the time required to detect anomalies can be reduced."
"The time taken to detect anomalies must be reduced."
"The network has been experiencing frustrating performance issues today, which is not typical for Nigeria."
More AWS Shield cons
"The solution should integrate with something that looks at continuous security management."
"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."
"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."
"The solution needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
"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."
"I'd like the option to pick your bot protection."
More Imperva Application Security Platform cons
 

Pricing and Cost Advice

"The price of the solution is expensive."
"The product's pricing is minimal compared to other products."
"The tool is a premium product, so it is very expensive."
"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."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"A free version of the solution is available."
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."
"The tool is cheap."
"The tool's pricing is good."
"We pay $3000 per month for the solution."
"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 cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"Imperva Web Application Firewall is expensive."
"There is a license or subscription renewal that our customers pay."
"The tool's pricing is good."
"The tool is expensive."
"It's an excellent product, but it can be very costly."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"It is expensive."
