Executive SummaryUpdated on Dec 5, 2024

Imperva DDoS and AWS Shield are competing products in the domain of distributed denial-of-service attack protection. AWS Shield holds an advantage due to its seamless integration with AWS infrastructure, making it more appealing to AWS-centered businesses, while Imperva DDoS gains preference for pricing flexibility and superior support.

Features: Imperva DDoS offers real-time security updates, comprehensive multi-layered attack defense, and robust threat detection and mitigation. Complementing AWS services, AWS Shield provides automatic protection, requires no customer intervention, and features advanced attack analytics. Each product effectively caters to its user base, with AWS Shield benefiting AWS users through native integration.

Room for Improvement: Imperva DDoS could enhance its integration with third-party infrastructures, improve its user interface for easier navigation, and speed up the deployment process. AWS Shield could benefit from expanding its protection scope outside the AWS ecosystem, making its user interface more accessible to those unfamiliar with AWS, and offering more detailed reporting options for non-AWS integrations.

Ease of Deployment and Customer Service: AWS Shield stands out with its straightforward deployment, especially advantageous for AWS users due to minimal latency and automatic protection features. Imperva DDoS offers enhanced deployment support with a dedicated team, appealing to users needing extra assistance. While AWS Shield's integration benefits AWS clients, Imperva shines with accessible customer service for guidance.

Pricing and ROI: Imperva DDoS provides competitive pricing with flexible plans, catering to businesses with evolving needs, possibly offering a lower overall cost. AWS Shield, bundled with AWS services, delivers value within the AWS framework with predictable costs and potentially higher ROI for AWS users. Although AWS Shield's cost-effectiveness suits existing AWS customers, Imperva might offer more economical options for businesses with varied needs.

Solution provides essential protection with good support and a simple setup

I have noticed a pattern developing in approximately five minutes. If it were possible to provide these patterns with historical data spanning six months, three months, or two months directly from the console, it would be extremely beneficial. It would allow for easy inquiries and facilitate the retrieval of relevant parts without having to manually check logs or examine movements. Instead, if all historical data were available, I could consult six months' worth of identified patterns efficiently through AWS without relying on external sources. This solution is particularly suitable for startups or medium-sized startups. I would rate the overall solution eight out of ten.

Provide DDoS protection and better security at effective rate

It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.

Quotes from Members

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

Pros

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

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

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

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

"It blocks all types of attacks."

"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."

"On the real time, you can see live traffic, which is flowing into our website."

"There is no need to have an appliance in house for the services because it is on the cloud."

"It is a stable solution."

"The most valuable features for us are the DDoS and Bot."

"Imperva DDoS is fairly stable, and its availability is quite high."

"We have peace of mind that nobody will use malware on us or try to hack our website."

More Imperva DDoS pros

Cons

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

"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."

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

"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."

"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."

"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."

"It's quite expensive."

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

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

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

"Imperva DDoS does not provide version control."

"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."

"Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers."

Pricing and Cost Advice

"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."

"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."

"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."

"The license is on a yearly basis."

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

"It is expensive."

"It is not expensive compared to the other similar solutions in this category."

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

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

"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."

Imperva Incapsula

Overview

AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards applications running on AWS. AWS Shield provides always-on detection and automatic inline mitigations that minimize application downtime and latency, so there is no need to engage AWS Support to benefit from DDoS protection.

Amazon Web Services (AWS)

Imperva DDoS is a solution that offers protection for web applications and websites and all their associated business-critical data from cyberattacks. The cloud-based application delivery service helps improve user experiences by improving their performance. Through its security platform, Imperva DDoS also provides DDoS mitigation, a web application firewall, and a global load balancer, and includes a content delivery network — all designed to maximize performance.

Imperva DDoS Features

Imperva DDoS has many valuable key features. Some of the most useful ones include:

API security
Web application firewall
Bot management
Application delivery
Runtime protection (RASP)
Discovery and assessment
Data protection
Data risk analytics
Data privacy
Application delivery control (ADC)
Content delivery network (CDN)
DDoS mitigation
Global server load-balancing (GSLB)
Web application firewall (WAF)
Client-side protection
Runtime protection

Imperva DDoS Benefits

There are several benefits to implementing Imperva DDoS. Some of the biggest advantages the solution offers include:

Reduce web application risk: Imperva DDoS includes automatic policy creation and fast rule propagation that give your IT and security departments the ability to use third-party code without risk while working at the pace of DevOps.

Security from edge to database: Imperva DDoS’s WAF feature secures from edge to database, so the traffic you receive is only the traffic you want.

Safeguard sensitive and personal data: Imperva DDoS provides visibility into sensitive and personal data, with the controls to protect that data and the ability to unify management across cloud, on-premises, and in hybrid environments to help accommodate changing threats, new regulations, and challenging audits.

Reviews from Real Users

Below are some reviews and helpful feedback written by Imperva DDoS users.

PeerSpot user, Etienne W., CDN & Cybersecurity Engineer - Web performance & security at CDN Tech / Ecritel, says, “It is a good solution that allows us to protect websites. It is stable, scalable, quick and easy to use.” He goes on to explain, “WAF protection works almost out-of-the-box. The Anti-DDoS mitigation in less than 1s, I saw it many times in production, I can say it works. CDN has high performances, and the Smart Caching mode is really "smart" (you can do some efficient caching even if you're not a specialist). Its unique interface for managing security performance and ease of use are the most valuable features of this solution."

An IT Senior Manager at an outsourcing company mentions, “The most valuable features are DDoS protection. The Incapsula [Imperva DDoS] environment helps us monitor all the web activity. All the web activity is passed through their WAF cloud services, then that can help us to monitor those activities. That can help protect against DDoS hacking.”

Another PeerSpot reviewer, Ben D., Sales Executive at EVVO LABS, comments, "Imperva Incapsula [DDoS] has many valuable features. One, it protects the top 10 OWASP vulnerability, the open web application software platform, this is standard. Secondly, it protects against broken authentication. As well, it has remote execution of code."

A Solutions Architect at a financial services firm states, “The solution's most valuable aspect is that it is easy to configure. The solution keeps itself up to date itself and there's no customization that we need to do. It makes it extremely easy and cuts back on the amount of work required, and saves us on man-hours.”
