The Zero Trust Maturity Model 2.0 is divided into four stages, each of which specifically assesses an organization's security maturity and provides directions for development.

1. Traditional Stage (Static, Perimeter-based, Manual)

   • Features: Key components are static and managed manually. Security policies are limited to perimeter-based, and incident response is also manual.

     • Policy: Static security policies

     • Visibility: Limited, with a lack of real-time visibility into assets and networks

   • Example: Operated with only traditional firewalls and network-based access control.

2. Initial Stage (Partial Automation)

   • Features: Some security processes are automated, and integration among core security elements is limited.

     • Policy: Semi-automated policy application

     • Visibility: Partial visibility into key assets

   • Example: Adoption of multi-factor authentication (MFA) and use of dynamic access control only for specific use cases.

3. Advanced Stage (Automated, Centralized, Integrated)

   • Features: Centralized security policy and management with expanded scope of automation, and strengthened integration between systems.

     • Policy: Automated policy execution

     • Visibility: Real-time visibility across the organization

   • Example: Utilization of centralized policy engines and analytics-based automation tools.

4. Optimized Stage (Dynamic, Fully Automated)

   • Features: Dynamic policies are generated and applied automatically, managing all asset and resource attributes in real time.

     • Policy: Real-time dynamic policies

     • Visibility: Complete visibility and predictive analytics

   • Example: AI-based predictive analytics, threat detection, and autonomous security policy execution.

Flexible Application of Maturity Model 2.0

The adoption of Zero Trust by organizations requires gradual development and a customized approach. However, not all organizations need to reach the optimized stage.

• Customization to Organizations: The maturity model can be adapted according to the size of the organization, industry characteristics, and regulatory requirements.
  For example, small businesses may realistically start at the "Initial Stage" and develop gradually, while large financial enterprises may approach from the "Advanced Stage".

• Selection based on Resources and Goals: The required technologies and processes at each stage can be chosen according to the organization's budget and priorities.
