Credential-based ZTA are a promising new approach for strengthening authentication policies, which is specially suitable for a transformed ecosystem where perimeters and boundaries have already vanished, in favour of ubiquitous access to both cloud and edge computing models. The new eIDAS 2 regulation proposal, properly implemented, will provide a legal trust anchor for these new approach, bringing legal certainty and fostering adoption. The roles of distributed ledgers as EBSI will be explored as well.
