AWS Shield vs Tinfoil Security: What are the differences?

Developers describe AWS Shield as "Managed DDoS Protection". AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards web 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. On the other hand, Tinfoil Security is detailed as "Routine scans of your website’s security health and vulnerabilities". Our automated scan checks for vulnerabilities in every nook and cranny of your website. Using the same techniques as malicious hackers, we systematically test all the access points, giving you step-by-step instructions on how to eliminate any threat.

AWS Shield and Tinfoil Security can be categorized as "Security" tools.
