Zero-trust era has arrived. How can organizations build an ultimate security architecture?

With digital transformation, remote work, and cloud adoption blurring traditional “trust boundaries,” Zero Trust has become the cornerstone of modern cybersecurity. Taiwan is moving fast: the Financial Supervisory Commission’s Cybersecurity Action Plan 2.0 makes Zero Trust a core goal, while the National Cybersecurity Research Institute is urging top-tier government agencies to speed up adoption. Globally, Gartner reports that more than 60% of enterprises have already implemented Zero Trust. Yet many organizations still struggle with a lack of integrated defense services and cybersecurity expertise—leaving them vulnerable to emerging threats.

Never trust, always verify.

Traditional defenses such as firewalls, intrusion detection, and prevention systems are no longer sufficient, as enterprise boundaries now extend far beyond on-premises systems. Based on the principle of “Never trust, always verify,” Zero Trust assumes that threats may exist both inside and outside the network. No user, system, or device is trusted by default. Its core principles include:
1.Assume breach: Every network request is treated as a potential threat and must be verified.
2.Least privilege:Users and devices receive only the minimum access required.
3.Continuous monitoring:Access policies are dynamically adjusted through real-time detection.

Challenges to Zero Trust Adoption

Dr. Chase Cunningham, “the father of Zero Trust,” highlights three major obstacles for enterprises:

1. Lack of interoperability:Existing infrastructure often cannot support identity, segmentation, and real-time monitoring integration.
2.High cost and resource demand:Deploying Zero Trust requires significant investment, especially for SMEs lacking expertise. Starting with high-risk areas like data access is recommended.
3.Cultural resistance:Zero Trust is a risk management strategy, not a sign of mistrust. Successful adoption requires leadership support, employee education, and clear communication.

According to Fortinet’s Zero Trust Report, enterprises relying on multiple legacy security products face higher risks of vulnerabilities and rising operational costs, slowing Zero Trust progress.

OmniStor: From Passive Defense to Proactive Governance

To strengthen Zero Trust practices in data security, ASUS Cloud developed OmniStor, a Zero-Trust File Management System (ZTF). OmniStor delivers enterprise-grade private cloud architecture for multilayered data governance and protection. Covering identity authentication, data access, and threat defense, it offers flexible deployment models and a unified, compliant, and secure approach to file management.

OmniStor in Action: Mapping to Zero Trust Principles 

Echoing the three core principles of Zero Trust — “Never trust, always verify,” “Least privilege,” and “Continuous monitoring” — OmniStor provides the following corresponding features:

PrinciplesOmniStor feactures
Never trust, always verify.
  • Two-factor authentication (2FA)
  • Mobile PIN verification
  • Login via DB, LDAP(s), SAML, or OIDC
  • BYOD controls with account-device binding
Least Privilege
  • Role-based admin controls
  • IP whitelisting for backend access
  • Download/export restrictions with approval workflows
  • Sharing controls with black/whitelists
  • File format and privacy safeguards
  • Configurable external access (e.g., FTP)
Continuous Monitoring
  • Data Protection Mechanism — If uploaded files contain viruses, the system will alert users and block storage or upload.
  • Detailed audit logs (user activity, folder permissions, sharing records, admin changes)
  • Regular security assessments, including vulnerability scans, code reviews, and penetration testing
