InstaSafe Zero Trust Application Access vs Zscaler B2B comparison

InstaSafe® Secure Access solution provides an identity based granular access control solution based on the principles of Software Defined Perimeter (SDP). SDP concepts have been derived from the military, especially the Defense Information Systems Agency (DISA), where every device is pre-attested before it can ‘connect’ to the network followed by verification of the identity of the user using MFA leading to knowing exactly what device was being used and by whom to access the application.

With the device & user’s knowledge, ISA is able to ensure that the device and the user are able to only ‘see’ and ‘access’ the data, that they have ‘prior approval’ to see or access – the ‘need-to-know’ access model.

Zscaler B2B (ZB2B) is a cloud service that provides your business customers fast, seamless, and secure access to applications over the internet, whether they’re hosted in the data center or public and private clouds.

ZB2B is based on a service-initiated zero trust network access (ZTNA) architecture and uses business policies to securely connect an authenticated customer to an authorized app, without ever exposing the app to the internet or bringing the customer on your network.

ZB2B brings cloud scale and agility to customer access by eliminating the complexity and friction of legacy network and security infrastructures.
