Adding a security.txt file enables security researchers to quickly and
easily see where they can submit security issues and know that they are
being taken serious. From the proposal website:
> "When security risks in web services are discovered by independent
security researchers who understand the severity of the risk, they often
lack the channels to disclose them properly. As a result, security
issues may be left unreported. security.txt defines a standard to help
organizations define the process for security researchers to disclose
security vulnerabilities securely.”
