InstaSafe ZTAA relies on continuously assessing the trust and risk associated with every user, and the context of their access request, and simultaneously employs a system of comprehensive authentication before grnating least privilege access. By only making authorised applications accessible to the user, and not exposing the network to these users, ZTAA serves to negate the exploitable attacks surface
