Zero Trust is a cybersecurity framework that eliminates the assumption of trust in any user, device, or system inside or outside a network. Instead of relying on perimeter-based defenses, Zero Trust enforces strict identity verification, continuous monitoring, and least-privilege access to minimize security risks.

At its core, Zero Trust operates on the principle of “never trust, always verify.” Traditional security models often assume that anything inside the corporate network is inherently safe, but with the rise of cloud services, remote work, and sophisticated cyber threats, that assumption is no longer viable. A Zero Trust approach requires authentication and authorization for every request, regardless of where it originates.

A well-implemented Zero Trust strategy typically includes:

• Identity and Access Management (IAM): Ensures users and devices are authenticated before granting access.
• Least Privilege Access: Limits access rights to only what is necessary for a user or system to perform its function.
• Microsegmentation: Divides networks into smaller, isolated segments to prevent lateral movement in case of a breach.
• Continuous Monitoring: Uses real-time analytics, behavioral analysis, and automated threat detection to identify anomalies.
• Multi-Factor Authentication (MFA): Requires multiple verification factors to strengthen identity security.

Zero Trust benefits organizations by reducing attack surfaces, improving compliance, and mitigating insider threats. While adoption may require changes in infrastructure and workflows, the long-term gains in security and resilience make it a critical strategy for protecting sensitive data and systems.
