The previous few years have seen an explosion of curiosity in Zero Belief Community Entry (ZTNA). The zero trust strategy replaces the perimeter protection mannequin with a “least privilege” framework the place customers authenticate to entry particular knowledge and purposes, and their actions are repeatedly monitored.
