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

"The most valuable feature is the web application firewall."

"Easier http to https redirect using page rules"

"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

"DDoS protection is this product’s most valuable feature."

"Generally, I am satisfied with this product."

More Cloudflare pros

"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 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."

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

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

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

"The product is easy to use."

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

"AWS Shield offers numerous protection features that are crucial at the application layer, safeguarding users from distributed denial of service attacks, man-in-the-middle assaults, and hacker orchestrations."

More AWS Shield pros

"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."

"It is the best product on the market, in my opinion."

"I would encourage people to implement Imperva Incapsula, as it is a very mature, easy to use, and reliable solution."

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

"We are using Incapsula as our web application firewall and for DDoS protection, and it performs really well at its job."

"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."

"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."

"Essentially, it has added an extra layer of protection to my clients through their DNS routing service."

More Imperva Application Security Platform pros

Cons

"DNS Management."

"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."

"The solution could work at being less expensive. It costs a lot to use it."

"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."

"The documentation could improve for Cloudflare DNS."

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

"There might be helpful if there was some web application firewall feature."

"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."

More Cloudflare cons

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

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

"The product is expensive."

"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."

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

"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."

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

More AWS Shield cons

"We've had some issues with them in terms of response times, but overall they are okay."

"The firewall aspect of the solution needs improvement."

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

"Imperva now offers add-ons to add functionality, but I would like to see these included in the product, even if it would cost more."

"The product could use a broader scope in the area of policies."

"Pricing can be improved, as it is quite expensive."

"It would be beneficial to include vulnerability management in the solution, similar to what they have for their on-premise solution."

"Our support is currently coming from the US, and it is not very good."

More Imperva Application Security Platform cons

Pricing and Cost Advice

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

"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."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

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

"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."

"We are using the free version."

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

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

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's pricing is good."

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

"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."

"Imperva Web Application Firewall is expensive."

"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."

"The price of this solution is a little bit high compared to competitors."

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

"The tool is expensive."

"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."

"The price of Imperva Web Application Firewalls is expensive compared to others."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."
