Zero Trust is a cybersecurity framework that eliminates implicit trust within an organization’s network. Instead of assuming that users or devices inside the network are safe, Zero Trust requires continuous verification, strict access controls, and least privilege principles to prevent unauthorized access and cyber threats.
Key Principles of Zero Trust
- Verify Everything - Every user, device, and application must be continuously authenticated and authorized before gaining access.
- Least Privilege Access - Users and systems are granted only the minimum level of access necessary to perform their tasks, reducing the risk of insider threats.
- Micro-Segmentation - The network is divided into isolated segments to limit lateral movement, preventing attackers from spreading if they gain access.
- Continuous Monitoring - Real-time threat detection and behavior analysis help identify anomalies and potential security breaches.
- Encryption & Secure Access - Data is encrypted in transit and at rest, and access is secured through multi-factor authentication (MFA) and endpoint security.
Why Zero Trust is Important for Businesses
- Protects Against Insider & External Threats - Prevents unauthorized users, compromised accounts, or malware from moving freely within the network.
- Supports Remote & Hybrid Work - Ensures secure access for employees, third-party vendors, and contractors from any location.
- Enhances Compliance - Helps organizations meet PCI DSS, GDPR, HIPAA, and NIST security requirements by enforcing strong access controls and data protection.
- Reduces Attack Surface - Limits potential entry points for cybercriminals by securing devices, cloud applications, and endpoints.
