TL;DR: The UAE’s smart-city and IoT expansion depends on TLS, but constrained devices, massive certificate volumes, and mixed protocols make manual certificate management fragile, according to eMudhra. The real security issue is not encryption itself but whether device identity, renewal, revocation, and key custody can scale without creating outage and spoofing risk.

By the numbers:
- 57% of organisations lack a complete inventory of their machine identities.
- Certificate expiry is the leading cause of outages for 45% of organisations.
Questions worth separating out
Q: How should security teams manage TLS certificates across large IoT fleets?
A: Security teams should manage IoT certificates through automated lifecycle workflows, not spreadsheets or ticket queues.
Q: Why do IoT devices make certificate governance harder than server workloads?
A: IoT devices are harder to govern because they are numerous, heterogeneous, and often physically exposed.
Q: What breaks when certificate expiry is handled manually in smart infrastructure?
A: Manual expiry handling breaks continuity first and security second.
Practitioner guidance
- Map the full device identity inventory Build an authoritative inventory of every IoT endpoint, gateway, certificate authority dependency, and trust anchor.
- Automate certificate renewal and revocation workflows Use policy-driven issuance, auto-renewal, and immediate revocation hooks so expired certificates do not become outages.
- Protect private keys with hardware-backed custody Store private keys in secure elements or FIPS-certified HSMs for gateways and critical endpoints.

Certificate lifecycle is now an identity governance problem, not a PKI back-office task. In IoT estates, the certificate is the device’s identity token, and every renewal or revocation event is an access decision. That means inventory, ownership, and lifecycle control matter as much as encryption strength. Practitioners should stop treating TLS as transport plumbing and start governing it as NHI identity.
A few things that frame the scale:
- Certificate expiry is the leading cause of outages for 45% of organisations, according to The Critical Gaps in Machine Identity Management report.
- Manual processes still dominate: 61% rely on spreadsheets or manual tracking for machine identity management, according to The Critical Gaps in Machine Identity Management report.
A question worth separating out:
Q: Who is accountable when an IoT certificate failure causes an outage?
A: Accountability usually sits across IAM, PKI, operations, and the business owner of the device fleet. If certificate renewal, key custody, and revocation were not assigned clear ownership, outage response becomes fragmented. Organisations need explicit control ownership for device identity because the failure is operational, security-related, and governance-driven at the same time.
