Neo4j Sandbox is not encrypted. Why?

The only provided ports are HTTP "7474" and unencrypted BOLT "7687"

Why isn't there an encrypted bolt connection available?

While I can't speak on behalf of Neo4j, I would imagine they don't have encrypted connections on the Sandbox because it is exactly that - a sandbox. It isn't designed to support actual applications.

That would have sufficed in a prehttps world. But not really an excuse anymore when certificates are free
