Defense in Depth is a cybersecurity strategy that employs multiple layers of redundant defensive measures to safeguard sensitive data, personally identifiable information (PII), and IT assets. The idea is simple: if one security control fails, the next layer steps in to thwart potential cyber attacks.

The traditional security model relied on network perimeters to protect against unauthorized access. However, with the rise of cloud applications and BYOD devices, network perimeters have become more porous, and perimeter defense is no longer sufficient. The Zero Trust model recognizes that identity is the new security perimeter and emphasizes the importance of never trusting any entity by default, regardless of its location or origin. Instead, it promotes the idea of always verifying and validating every stage of a digital interaction.
