As organizations increasingly place their data and applications across multiple locations on the cloud, zero trust security is rapidly gaining ground as the network security model of choice among enterprises.

Zero Trust Security is a security model in which a user, irrespective of whether he/she is within or outside the network perimeter, requires an additional verification to get access into a network. There is no particular technology or software product associated with this security model. It simply requires an additional security layer to verify users. This could be anything from biometric verification like thumb-print scanning, or a digital signature verification. Of the two, biometric verification is preferable as it can neither be recreated nor hacked.
