Executive SummaryUpdated on Dec 5, 2024

Corero and AWS Shield are products in the DDoS protection category. AWS Shield has an upper hand in scalability and AWS service integration, whereas Corero is appealing with its competitive pricing and robust support.

Features: Corero provides comprehensive DDoS protection, real-time reporting, and analytics for quick threat identification. It is cost-effective and offers dedicated support. AWS Shield offers seamless integration with AWS services, high scalability, and automated threat detection.

Room for Improvement: Corero could enhance its scalability to rival AWS Shield and improve its integration capabilities. Its user interface, while informative, could also be more intuitive. AWS Shield can work on lowering costs for non-AWS users and enhancing its reporting features. Improved customer service responsiveness would also benefit AWS Shield.

Ease of Deployment and Customer Service: Corero provides straightforward deployment and excellent customer support, simplifying the process for companies with no existing infrastructure. AWS Shield offers easier deployment for AWS users due to its tight integration within the AWS ecosystem, but relies more on automated systems, which might impact personalized support.

Pricing and ROI: Corero is known for lower setup costs and compelling ROI, especially for enterprises focusing on efficiency and budget. AWS Shield, although more expensive, offers value primarily to businesses heavily invested in AWS, with potential cost savings through integration efficiencies.

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.

Effective network and DDoS protection with suitable pricing

Quotes from Members

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

Pros

"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."

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

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

"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."

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

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

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

More AWS Shield pros

"The most important aspect, in general, is that the price is suitable for most clients."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"This is a hybrid solution."

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."

"The DDoS protection features are valuable."

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."

"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."

Cons

"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."

"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 product is expensive."

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

"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."

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

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

More AWS Shield cons

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."

"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."

"The product must provide more Layer 7 capabilities."

"Lacks international presence."

"It could use support in Spanish."

Pricing and Cost Advice

"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."

"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 is cheap."

"The price of Corero is affordable."

"Its price is normal."
