TL;DR: Device growth, attack volume, and unsupported firmware are widening IoT risk faster than many governance models can absorb, Ordr analysis says. Inventory gaps and stale ownership leave connected devices able to stay trusted long after support or patch status changes.
Editorial analysis by NHI Mgmt Group, based on content published by Ordr: “IoT Security Statistics”.
By the numbers:
- Connected devices now number over 21 billion globally and are projected to reach 39 billion by 2030.
- More than 50% of all IoT devices contain critical vulnerabilities that attackers can exploit immediately.
- Routers account for over 75% of all IoT-related cyberattacks.
Key questions
Q: Why do insecure IoT devices create broader enterprise risk?
A: Because once connected devices are inside a trusted environment, they can be used as entry points, persistence platforms, or sources of false data.
Q: What are the signs that IoT segmentation is failing in practice?
A: Warning signs include camera traffic that suddenly scans subnets, talks to new internal hosts, or reaches services outside its normal video-management path.
Q: What breaks when smart devices are integrated without lifecycle governance?
A: The environment becomes dependent on fragile pairings, repeated manual reintegration, and unclear ownership of trust.
Practitioner guidance
- Build a complete connected-device inventory Classify every IoT, OT, and IoMT asset by owner, firmware status, exposure level, and business criticality so patching and segmentation decisions are based on facts, not discovery drift.
- Isolate unsupported and high-risk devices first Move routers, cameras, and controllers that cannot be patched or replaced into restrictive zones with minimal east-west access and explicit communication allowlists.
- Map device communications before enforcing policy Use passive monitoring to identify normal device-to-device traffic, then build network rules around actual communication patterns rather than assumptions about how the environment should behave.
Bottom line: IoT risk is accelerating because device growth, attack volume, and unpatchable firmware are expanding faster than many governance models can absorb.

IoT security is now an access-governance problem, not only a device-hygiene problem. The article's numbers show that volume, vulnerability, and unsupported firmware are combining to create an environment where devices behave like semi-persistent identities with network reach. That means security teams must think in terms of trusted onboarding, ownership, and lifecycle control, not only vulnerability scans. Practitioners should treat connected devices as governed access participants, not passive hardware.
A question worth separating out:
Q: How should organisations prioritise IoT remediation when device counts are high?
A: Prioritise devices that are both exposed and difficult to patch, especially routers, cameras, and unsupported controllers. Then focus on assets that sit at the boundary between business networks and operational systems, because those devices offer the highest likelihood of initial access and the widest downstream impact.
