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.

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.

reviewer2818155

Senior Associate at a tech vendor with 10,001+ employees

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

"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."

"Cloudflare consolidates various capabilities into one product, streamlining processes."

"Cloudflare has many features."

"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."

"Centralized, full-featured DNS."

"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."

"The most valuable feature is its usability."

"The tool is user-friendly."

More Cloudflare pros

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

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

"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."

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

"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."

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

"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 dynamic profiling of websites is the solution's most valuable feature."

"Basic setup is simple but, as with any caching/WAF setup, there are tricks you need to learn, but it works really nice out of the box!"

"Incapsula can help to hide the real origin and provide access control over different pages, and it can protect the website from being attacked."

"Incapsula provides a very simple to install and configure solution, that can be up and running in minutes."

"Bad-IP blocking and signature-based blocking for web application security."

"Well, just by using the security rules to block all secured areas by IP minimized the chance of sensitive data leaking outside."

"The three-second service level agreement is already better than the competition."

"The most important feature I have found is the ease of doing backups and restores."

More Imperva Application Security Platform pros

Cons

"Support response time could be improved."

"There should be a specific price list for enterprise-level customers."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"If they improve on the placement of their data centers, it would be better."

"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 would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."

More Cloudflare cons

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

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

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

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

"Perhaps the time required to detect anomalies can be reduced."

"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."

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

More AWS Shield cons

"The signature updates could be faster. Sometimes we have to upload signatures to the Imperva portal for checking and analysis before we can use them."

"I'd like the option to pick your bot protection."

"The support for the on-premises version needs improvement."

"I would like to improve the tool's turnaround time in terms of support."

"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."

"We faced challenges with high costs, as the customer perceived pricing for gateways to be excessive, but we handled multiple billing instances with sophisticated setups."

"Its user interface could be improved, as the competition looks better, but it doesn’t really need improvements in its functionality."

"Management of policies and rules can be complicated and the physical setup of the product has implications on HA."

More Imperva Application Security Platform cons

Pricing and Cost Advice

"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."

"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."

"That is one of the great features. I was able to access the majority of the features and services for free."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

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

"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."

"The tool is a premium product, so it is very expensive."

"We don't have any issues with the price."

More Cloudflare pricing and cost advice

"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."

"The tool's pricing is good."

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

"The cost of this solution depends on the platform."

"It is expensive."

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

"The tool's pricing is good."

"The license is on a yearly basis."

"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."

"The price is high compared to other solutions like FortiWeb."
