Organisations are now deploying AI agents at unprecedented speed and scale. As one study noted, many companies now have hundreds of AI identities for each human employee, and almost all of them lack adequate governance. This unchecked proliferation introduces new attack surfaces, credential sprawl and network blind spots. Security teams must shift from reaction to foresight, and treat AI agents like users, services or infrastructure components not side experiments.
The framework presented here guides security professionals through three essential pillars: Govern Identity, Embed Security by Design, and Accelerate with Oversight. By aligning speed and control, this framework helps organisations move fast without surrendering risk.
Treat AI Agents as First-Class Identities
Every AI model, script or autonomous agent functions like a user account: it processes data, issues commands and influences critical systems. Therefore, organisations must apply the same discipline to AI identities as they do to human users. This means authenticating each agent, assigning least-privilege, rotating credentials frequently and logging actions for audit.
Moreover, segmentation is vital. AI agents should operate within defined scopes to prevent one compromised agent from influencing others. In practice, this requires modelling each AI system’s ownership, lifecycle and monitoring as part of the identity and access management (IAM) strategy.
Architect for AI from Day One
Legacy security tools rarely anticipate workloads composed of hundreds of autonomous agents interacting, scaling, and modifying themselves. Consequently, organisations must adopt security by design during AI deployment not wait until an incident occurs. The core approach involves designing for visibility, controlling credential sprawl and aligning AI operations with business objectives.
To achieve this, teams should:
-
Locate and inventory all AI agents and their access patterns.
-
Enforce policies about what each agent can and cannot do.
-
Prioritise encryption, audit logs and access controls for data consumed or produced by AI.
-
Monitor for lateral movements or orchestration beyond expected scopes.
By embedding these controls early, organisations reduce risk even as they accelerate AI adoption.
Accelerate with Oversight: Align Speed and Control
High-velocity AI deployment does not mean abandoning oversight. Instead, it requires building a governance layer that allows rapid innovation while monitoring for drift, unintended actions or abused privileges. Organisations should track metrics such as agent proliferation rate, credential usage, anomalous behaviour and resource consumption. These metrics feed dashboards that leadership and security teams review regularly.
This oversight not only preserves security but also enhances business value: when security teams partner with the business and demonstrate control, they shift from being a roadblock to an enabler.
As the number of AI agents in enterprise environments grows, unchecked adoption risks turning innovation into jeopardy. Organisations must act proactively: govern identities, embed security by design, and build oversight that supports speed without sacrificing control. Using this framework, security teams can stake a claim on AI not as an afterthought but as a strategic accelerator.
FAQs
Q1: Why must AI agents be treated like user identities?
A1: Because each agent can access data, issue commands and influence systems, it behaves as a new identity. Applying IAM controls authentication, least privilege, audit ensures the system is governed like any other critical user or service.
Q2: What is credential sprawl and why is it dangerous in AI deployments?
A2: Credential sprawl occurs when too many identities (human or machine) have excessive or unmanaged access. In large-scale AI deployments, hundreds of agents may carry credentials, increasing the attack surface significantly unless controlled.
Q3: How does embedding security by design differ from traditional security methods?
A3: Traditional security often reacts to incidents; embedding security by design means building safeguards during the deployment phase of AI—visibility, access controls and lifecycle policies so risk is managed proactively.
Q4: What oversight metrics should security teams monitor for AI at scale?
A4: Key metrics include agent proliferation rate, credential usage patterns, anomalous agent behaviour, privilege escalation events, and resource consumption spikes. These help track drift and control over AI systems.
