Zero Trust

Never assume. Always verify.

Zero Trust is basically not giving everyone the master key just because they walked into the building.

What it means

Old model: once someone gets in, everything is open. Zero Trust: every door asks, who are you, prove it again.

Scenario

Let’s say an attacker gets hold of the password of someone in your organisation.

They log in. No alarms go off, because the credentials are valid. In traditional security, once they’re in they can move around the network like any employee. They start exploring systems, checking shared drives, databases and servers. They escalate access, create backdoors, download data, all undetected.

That lateral movement is the real danger.

With Zero Trust

A compromised password becomes a contained incident, not a company-wide outage. Each system re-verifies the user. It’s like containing a fire in one room instead of the entire floor burning down. The blast radius stays tiny.

Why it matters

This part is far more important than the buzzword itself. Attackers rarely break through firewalls. They walk in through legitimate logins. Zero Trust limits the damage even when they get in, which is why it isn’t optional any more. It’s a foundational control.
