What is zero-trust architecture, and why do we need it?

I reminisce about the days when corporate security relied on a firewall with strict in-out rules, and the primary threat appeared to come from the outside.

At that time, trust among everyone was prevalent.

Fast forward to 2024, and we’re facing a new reality. Hacking techniques have evolved, leading to a surge in targeted attacks. Ransomware incidents are on the rise, and data leaks are no longer just threats from outsiders, but also insiders or disgruntled former employees. This evolution demands a new approach to security.

Trust, once abundant, has now become a rare commodity in the cybersecurity landscape.

Since its inception in 2009, zero-trust architecture has been gaining popularity. It is recognized for adding an internal layer of security, safeguarding every resource, and granting access only to those who need it, with continuous access verification.

This seems straightforward, but implementing such an architecture is complex, expensive, and challenging.

Zero-trust architecture is the right direction, especially as remote work becomes more prevalent and secure external access becomes essential.
