+	<p>SING supports, promotes, and structures the threat modeling for web standards and technologies. This approach can be used, along with other groups, for threats of different types such as security, privacy, and harm. Threat modeling is a joint activity with groups developing technology or other documentation and threat experts. It can be used to get an understanding of the impact of the technology and guide its development, as well as to write considerations.</p>
         <p>SING provides "<a href="https://www.w3.org/Guide/documentreview/">horizontal review</a>", offering groups on-request guidance on security issues and mitigations specific to their technologies. SING aims to offer this review as early in the technology development lifecycle as requested, observing that early feedback is often more helpful. SING may also seek out technologies that benefit from earlier security reviews and conduct such reviews on its initiative.</p>
         <p>SING incubates standards work on security issues by collecting requirements, prototyping, and/or initiating the work within the IG and recommending that the W3C move the work into other groups when appropriate.</p>
         <p>SING may recommend mitigations for security issues in existing features of the Web platform, up to and including their deprecation.</p>
