ReadonlyREST is the security plugin that levels Kibana up, enabling multi-tenancy. Today, thanks to ReadonlyREST, hundreds of organizations are saving money by segregating the data of many tenants into a single, larger, evenly loaded Elasticsearch cluster. Granting a new tenant access to their new, blank slate, logical instance of Kibana is as easy as adding a new user to the "kibana tenants"​ group in the organizations'​ LDAP or SAML, or any other central authentication server.
