Non-human identities (NHIs) are rapidly expanding across your systems. These digital identities access resources, execute tasks, and communicate with other systems — often with little or no human involvement.
You’ll find NHIs across infrastructure, applications, integrations, cloud platforms, automation environments, security systems, and network systems. They drive efficiency, accuracy, and productivity — but they also introduce new risks.
As NHIs evolve into fully agentic identities, they no longer just execute predefined tasks. They make decisions, adapt to context, and chain actions together in real time. This makes their behavior less predictable, meaning the actions they take can extend beyond what was originally intended when permissions were granted.
At the same time, AI and automation are driving rapid identity sprawl, with as many as 144 NHIs for every human identity. This combination of unpredictable behavior and exponential growth makes it significantly harder to maintain control, creating major challenges for how you design your Privileged Access Management (PAM) strategy.
A modern approach that governs every type of identity strengthens not just security, but overall business performance. Here are six reasons why it’s now essential.
The scale of identity sprawl driven by NHIs is significant and constantly increasing. This includes:
This rapid growth increases your attack surface, enabling lateral movement and persistent access risks — especially when monitoring and multi-factor authentication (MFA) are weak.
At the same time, many organizations overestimate their readiness. While 87% believe their identity security posture can handle AI-driven automation at scale, 46% report weak governance around AI systems. As identities become more autonomous, governance gaps become more pronounced.
Legacy PAM models were designed for human users, not machine identities. They assume static accounts, lack integration with modern pipelines, and focus primarily on human administrators.
This creates technical debt, expands your attack surface, and leaves open vulnerable entry points for lateral movement.
A modern approach secures both human and machine-driven identities through automation-first architecture, dynamic secrets management, and continuous monitoring. The result is stronger visibility, tighter control, reduced risk, and seamless integration across DevOps, cloud, AI, and automation environments.
A modern PAM strategy supports a long-term shift toward continuous authorization and Zero Standing Privilege. This ensures that AI agents and NHIs are governed with the same rigor as human identities, with full auditability of every privileged action.
The result is a measurable improvement in your security posture — real-time, context-aware governance, reduced standing access, and tighter control over privileged activity.
By moving from session-based to action-level authorization, and treating all access as ephemeral by default, your organization is prepared for both current and emerging AI-driven identity models.
Regulatory requirements increasingly extend to machine identities, making PAM a critical focus for auditors and regulators.
A modern approach demonstrates clear control by replacing manual processes and static credentials with automated, policy-driven enforcement. For example:
This positions you to meet compliance requirements more efficiently — and with greater confidence.
Managing PAM manually introduces significant operational overhead. Credential rotation, session monitoring, onboarding, infrastructure management, ticket handling, and compliance reporting all consume time and resources.
Consider a request for domain admin access. In a traditional model, this process can take up to a week due to approvals, provisioning, and password rotation. With automation, it can be completed in minutes.
This shift reduces costs, improves efficiency, and minimizes risk. A Business Value Assessment helps quantify these gains, giving you a clear case for investment, not just for security leaders, but for the broader C-suite.
When aligned with automation, PAM becomes a strategic enabler, not just a security control.
By securing all identities — human and machine — you improve resilience, reduce administrative burden, and remove barriers to adoption for new technologies. This allows you to move faster, adopt AI with confidence, and maintain strong security without slowing innovation.
To modernize your PAM approach, you need a structured, repeatable framework for managing NHIs across DevOps, cloud, automation, and AI-driven environments, which includes:
Success depends on more than implementation. You need a clear understanding of both the risks and the opportunities involved in managing human and machine identities together.
