protocols, including RSA and Elliptic Curve Cryptography (ECC). These algorithms protect everything
from online banking to military communications and networks.

Experts predict that large-scale, fault-tolerant quantum computers that can run Shor’s algorithm may
appear within 10-15 years (according to the estimates of IBM and Google quantum teams). When that
happens, the attackers will be able to decrypt the sensitive data, forge digital identities, and compromise
critical infrastructure. The clock is ticking.

Why Zero-Trust Architecture Is the Answer

Conventional security postures are based on the assumption that everything within the network is secure,
which is incorrect in the current environment. Zero-Trust Architecture changes this perspective with the
help of a single principle: Never Trust, Always Verify. It means that every user, device, and application is
considered a potential threat and requires confirmation of its good intentions.
