Zero Trust Security

Zero trust security is a cybersecurity model built on the principle that no user or device should be automatically trusted, whether inside or outside the company's network, and that every access request must be continuously verified before being granted. This approach represents a departure from traditional security models that often assumed anything already inside a company's network perimeter could be trusted by default. Under a zero trust framework, access to specific systems and data is granted based on strict verification of user identity, device security posture, and other contextual factors, evaluated continuously rather than just once at initial login. This often involves combining strong authentication methods, such as multi-factor authentication, with granular access controls that limit each user to only the specific systems and data genuinely necessary for their role. Zero trust security has become increasingly relevant as companies embrace remote and distributed work arrangements, since employees are frequently accessing company systems from a wide variety of networks and locations rather than exclusively from within a traditional, centrally managed office network. This makes the zero trust approach, which does not rely on a defined network perimeter for security, particularly well suited to protecting a distributed or international workforce.
