Question 1

What cybersecurity standards does TTMI align with?

Accepted Answer

TTMI platform architecture aligns with ISO 27001 for information security management, UN R155 for cyber security management, UN R156 for software updates, and ISO/SAE 21434 for automotive cybersecurity engineering.

Question 2

Can TTMI provide cybersecurity for systems outside SAAN Mobility?

Accepted Answer

Yes. TTMI cybersecurity capabilities are available as a standalone service for organisations using other fleet management or IoT platforms. We provide API integration where supported, or parallel deployment with consolidated monitoring.

Question 3

What is the difference between UN R155 and ISO/SAE 21434?

Accepted Answer

UN R155 is the regulatory mandate requiring vehicle manufacturers to implement a cybersecurity management system. ISO/SAE 21434 is the engineering standard that defines how to achieve it. R155 specifies what must be done; 21434 specifies how to do it.

Question 4

Does TTMI cybersecurity cover back-end systems, not just vehicles?

Accepted Answer

Yes. UN R155 Annex 5 explicitly includes back-end servers connected to vehicles. TTMI platform architecture is designed with this scope in mind, covering cloud infrastructure, APIs, and connectivity services.

Question 5

What is the typical compliance pathway?

Accepted Answer

Most organisations begin with ISO 27001 certification for company-level information security, then progress to UN R155 and UN R156 regulatory compliance, and finally achieve ISO/SAE 21434 engineering alignment.

Question 6

Does TTMI conduct threat analysis and risk assessment?

Accepted Answer

Yes. TTMI conducts formal Threat Analysis and Risk Assessment (TARA) per customer deployment, producing documented artefacts for regulatory and OEM audit requirements.
