What is a consequence of using traditional security models compared to Zero Trust?

Using traditional security models often involves a foundational assumption that devices or users within the network perimeter can be trusted. This leads to an increased vulnerability because once an attacker gains access inside the perimeter, they can exploit this trust to move laterally and access sensitive data or systems. Traditional models typically emphasize securing the perimeter, which can create blind spots and allow malicious actors to exploit vulnerabilities without being detected.

In contrast, the Zero Trust model operates under the principle that no one should be trusted by default, regardless of whether they are inside or outside the network. It assumes that threats can be present both inside and outside the network perimeter and, thus, continuously verifies users and devices, significantly reducing vulnerability. This shift in mindset and strategy helps organizations mitigate risks and tighten security controls, which is critical in an era where cyber threats are increasingly sophisticated.
