Managing Identity and Access Across an IoT-Driven World

The Internet of Things (IoT) is no longer experimental — it’s powering operations everywhere. From hospitals and factories to retail floors and supply chains, billions of connected devices now collect data, trigger automation, and keep businesses running.

Yet, every device, whether a camera, sensor, robot, or gateway, must be identified, authenticated, and authorized. That’s where Identity and Access Management (IAM) and Privileged Access Management (PAM) come in. They’re no longer just about people and passwords; they must now secure machines, software services, and workloads.

Organizations that modernize IAM for IoT gain a strategic edge. Those that don’t risk a growing sprawl of unmanaged, unpatched, and vulnerable devices that attackers will exploit.

Why Human-Only Identity Models Fail

Traditional IAM systems were designed for users on laptops or phones. IoT breaks that model. Devices are often “headless,” intermittently connected, long-lived, and preloaded with static credentials. They also talk device-to-device, not just device-to-cloud.

Identity lifecycles for IoT span manufacturing, onboarding, activation, attestation, rotation, and retirement — all at machine speed. Decisions must take into account firmware integrity, secure boot status, and network location. That means every “thing” must be treated as a first-class identity, governed by the principle of least privilege and verified continuously.

Customer Challenges: Where Internet of Things (IoT) Meets Identity and Access Management (IAM) Complexity

1. Chaotic Device Lifecycles

   Most teams lack scalable processes for onboarding, authenticating, rotating, and retiring device credentials. Without automated certificate management, embedded keys become “forever credentials,” expanding the attack surface and violating NIST baseline guidance.

2. Fragmented Tools and Policies

   Separate stacks for MDM/UEM, OT security, cloud IAM, and on-prem AD create policy silos. This inconsistency between data center, cloud, and edge environments leaves exploitable gaps, as highlighted by ENISA.

3. Third-Party and Supply Chain Risk

   Pre-provisioned devices from OEMs or integrators often lack attestation and provenance checks. Complex supply chains and geopolitical tensions amplify this risk.

4. Skill and Process Gaps

   IAM teams face steep learning curves in X.509, TPMs, TEEs, SBOMs, and zero-trust segmentation, while compliance teams struggle to audit device identities across jurisdictions, stretching limited resources.

5. Lack of Measurable Metrics

   Many organizations can’t track device posture, access fidelity, or remediation times. Without metrics, prioritization lags until a security incident forces action.

The Business Benefits: Why IAM Matters for IoT

IAM goes beyond risk management -they drive security, efficiency, and compliance across connected environments.

1. Stronger Security, Lower Risk

• Foundation of Zero Trust for IoT ecosystems.
• Authenticate every access request to reduce attack surfaces.
• Enforce least-privilege access and prevent credential theft.
• Automated credential rotation and short-lived certificates reduce breach costs, often exceeding $4.45M per incident.*

2. Greater Operational Efficiency

• Automate identity lifecycle for users and devices.
• Simplify provisioning, onboarding, and decommissioning.
• Reduce manual effort and human error.
• IAM tools can lower admin workloads by 30–40% and improve uptime and rollout speed.*

3. Continuous Compliance and Auditability

• Maintain audit trails across cloud, edge, and on-prem.
• Enforce uniform policies aligned with ISO, SOX, and NIST SP 800-213.
• Mature IAM programs see 50% fewer audit failures and reduced compliance costs.*

Total Cost of Ownership Advantage

Upfront investments in IAM/PAM pay off through:

• Fewer breaches and lower remediation costs.
• Reduced operational overhead.
• Avoided fines, downtime, and revenue loss.

Proactive IAM/PAM costs far less than reactive recovery.

Building an IoT-Ready IAM Strategy

• Unify identities for users, devices, and workloads.
• Automate credentials with short-lived certificates and renewal.
• Embed Zero Trust at the edge using least-privilege access and mutual authentication.

These principles enable secure, scalable IoT growth - essential as connections surge toward billions by 2030.

How Zones Help

As IoT expands, identity becomes the foundation of trust. With rising connections and growing identity-based threats, success depends on governing every identity - human, device, workload, and API - through a unified, zero-trust, policy-driven framework.
