Maturity Framework

The NHI Maturity Model

A comprehensive framework for advancing your organization's non-human identity security from discovery to automated governance.

5 Maturity Levels•Actionable Roadmap•10-minute read

Introduction

As organizations accelerate digital transformation, the number of non-human identities (NHIs), including API keys, service accounts, certificates, and tokens, grow exponentially. Yet most organizations lack a systematic approach to managing these critical credentials.

The NHI Maturity Model provides a clear roadmap for organizations to evolve from ad-hoc, reactive secret management to proactive, automated governance. This framework helps security leaders assess their current state, identify gaps, and prioritize investments for maximum impact.

The 5 Maturity Levels

Organizations typically progress through five distinct phases as they mature their NHI security practices.

LEVEL 1

Ad-Hoc

Reactive, manual processes

LEVEL 2

Aware

Discovery and visibility

LEVEL 3

Managed

Inventory and controls

LEVEL 4

Automated

Lifecycle automation

LEVEL 5

Optimized

Continuous governance

LEVEL 1

Ad-Hoc

At this stage, organizations have no centralized approach to managing non-human identities. Secrets are scattered across codebases, configuration files, and developer machines.

Characteristics

Secrets hardcoded in source code and configuration files
No inventory of API keys and service accounts
Reactive, manual response to credential leaks
Credentials rarely rotated or updated

Risks

High risk of credential exposure. Organizations at this level are vulnerable to credential theft, insider threats, and supply chain attacks. Recovery from incidents is slow and costly.

Path to Level 2

Conduct Secret Scanning

Scan repositories, logs, and configuration files for exposed credentials

Create Initial Inventory

Document known API keys, service accounts, and certificates

Designate Security Champion

Assign a team member to drive NHI security awareness

Path to Level 3

Deploy Secret Vault

Implement centralized secret management solution

Migrate Critical Secrets

Move high-risk credentials from code to vault

Implement Access Controls

Define RBAC policies for secret access

LEVEL 2

Aware

Organizations at this level have gained visibility into their NHI landscape. They know what secrets exist, where they're used, and who owns them.

Characteristics

Comprehensive inventory of all machine identities
Continuous scanning for exposed secrets
Ownership and accountability established
Risk prioritization based on exposure and permissions

Impact

Improved security posture. Organizations can now proactively identify and respond to credential exposures, significantly reducing time to remediation.

LEVEL 3

Managed

At this stage, organizations have implemented centralized secret management and enforce policies across all systems. Manual rotation processes are in place.

Characteristics

Centralized secret vault with encryption at rest
Role-based access control (RBAC) enforced
Regular credential rotation schedules
Audit logging and compliance reporting

Impact

Controlled environment. Organizations have established foundational security controls and can demonstrate compliance with regulatory requirements.

Path to Level 4

Implement CI/CD Integration

Inject secrets at runtime, remove from code

Enable Automatic Rotation

Configure automated credential lifecycle management

Deploy Just-in-Time Access

Implement dynamic, short-lived credentials

Path to Level 5

Implement ML-Based Anomaly Detection

Detect unusual credential usage patterns

Enable Policy-as-Code

Define and enforce security policies programmatically

Establish Security Metrics

Track KPIs and continuous improvement

LEVEL 4

Automated

Organizations at this level have eliminated manual processes through automation. Credentials are dynamically provisioned, rotated without downtime, and revoked immediately when no longer needed.

Characteristics

Automated credential rotation with zero downtime
Just-in-time credential provisioning
Real-time threat detection and response
Integration with CI/CD and deployment pipelines

Impact

Operational efficiency. Security teams spend less time on manual tasks and more on strategic initiatives. Incidents are automatically detected and remediated.

LEVEL 5

Optimized

The highest maturity level represents continuous improvement and proactive security. Organizations predict and prevent issues before they occur through advanced analytics and governance.

Characteristics

ML-powered anomaly detection and prediction
Policy-as-code with automated enforcement
Continuous compliance and risk scoring
Cross-functional security culture and training

Impact

Proactive security leadership. Organizations at this level set industry standards, contribute to open source, and continuously innovate security practices.

Sustaining Excellence

Continuous Improvement

Regular security posture assessments and metrics review

Knowledge Sharing

Contribute to industry standards and best practices

Innovation

Invest in emerging technologies and threat research
