The zero-trust security model entails a rigorous security framework that operates on the principle of never trust, always verify. In this approach, both internal and external users must continuously authenticate and validate their access to systems and data, regardless of location. This model reduces the risk of data breaches and helps organizations protect sensitive information by segmenting access rights and implementing strict security protocols. As cyber threats evolve, the zero-trust model offers a more proactive stance, focusing on identity verification and monitoring suspicious activities.
