Zero Trust for Remote Workforce

The Remote Work Security Challenge

Remote work introduces multiple security challenges: diverse devices, untrusted networks, increased attack surface, and difficulty enforcing security policies. Organizations must secure access while maintaining user experience and productivity.

Zero Trust Network Access (ZTNA)

ZTNA replaces traditional VPNs with application-level access controls. Users connect directly to authorized applications without accessing the broader network. This approach reduces attack surface, improves performance, and enables granular access control.

• Application-level access instead of network access
• Identity-based authentication and authorization
• Continuous trust verification
• Reduced attack surface and lateral movement
• Better performance than traditional VPNs

Device Trust for Remote Endpoints

Remote devices require rigorous security controls. Implement device posture assessment checking security software status, patch levels, and configuration compliance before granting access. Deploy EDR and enforce encryption on all remote devices.

• Posture assessment before access
• EDR deployment on all endpoints
• Disk encryption enforcement
• Regular security updates
• Asset inventory and tracking

Identity and Authentication

Strong identity verification is critical for remote access. Implement phishing-resistant MFA using FIDO2/WebAuthn, deploy risk-based authentication adjusting requirements based on context, and consider passwordless authentication for improved security and user experience.

Cloud Application Security

Remote workers access SaaS applications directly. Implement cloud access security broker (CASB) capabilities for visibility and control, deploy secure web gateways (SWG) for safe internet access, and use data loss prevention for sensitive information.
