 Score which represents how many security advisories impact your dependencies. Unlike previous scores, this score takes into account all dependencies, direct or indirect (basically, everything in `Gemfile.lock`). Score $1$ means no dependency has an active advisory, and it starts gravitating towards $0$ when new advisories are found.
