Who Horizon3 sounds like
Its building stands in security · threats · protection, among companies whose homepages use the same words: security, threats, protection. Region: security · risk · identity.
Neighborhoods are measured, not assigned: companies stand together because their own homepages use the same words. Nobody labels them.
