Which automotive cybersecurity regulation applies to my company?

It depends on your role and product. OEMs in categories M, N, and O must comply with UNECE R155 and R156, mandatory since July 2024. OEMs in category L (motorcycles, light vehicles) come into scope from December 2027. Tier-1 and Tier-2 suppliers must align with ISO/SAE 21434 by contractual cascade, plus the CRA for components outside vehicle type approval. Standalone digital mobility products fall under the CRA from December 2027.

How does UNECE R155 affect vehicle homologation and SOP timelines?

UNECE R155 makes cybersecurity type-approval mandatory for new vehicle types in categories M, N, and O since 2022, and extends to category L (motorcycles, mopeds, light quadricycles) from December 2027. Without a certified CSMS and vehicle-level evidence, OEMs cannot homologate the vehicle — directly blocking Start of Production.

Does the EU Cyber Resilience Act apply to automotive suppliers?

Yes, in most cases. Complete vehicles in categories M, N, O, and L are excluded from the CRA because they are already covered by UNECE R155. However, Tier-1 and Tier-2 suppliers fall under the CRA for digital components not regulated through type approval, as do standalone digital products (chargers, aftermarket devices, connected accessories) from December 2027.

What does ISO/SAE 21434 compliance require for automotive Tier-1 suppliers?

ISO/SAE 21434 requires Tier-1 suppliers to demonstrate a structured Cybersecurity Management System (CSMS) covering the full product lifecycle — from TARA and secure development through validation and post-SOP monitoring. OEMs increasingly require auditable evidence as a precondition for new RFQs.

What evidence do OEMs require from suppliers to demonstrate cybersecurity compliance?

OEMs request project-specific, traceable evidence: TARA documentation, cybersecurity concept, validation and penetration test results, and CSMS process records. Generic certificates are not enough — auditors look for engineering depth, not templated outputs.

Can cybersecurity be integrated into an ongoing project without redesigning the architecture?

Yes, when intervention happens early enough in the V-cycle. OTC's First Fast Diagnosis identifies which controls can be layered onto the existing architecture and which require structural changes — protecting both the SOP date and the original cost envelope.

How much does automotive cybersecurity engineering cost, and how is it typically scoped?

Engagements are scoped by phase and component criticality, allowing predictable investment aligned with project milestones. OTC's fixed-scope First Fast Diagnosis gives you a clear gap analysis and a costed roadmap before any larger commitment.

DIGITALIZATION

From offline to intelligent.
Digitalization, scalable by design.

Digitalization means more than connectivity — it's the intelligence layer that turns data into decisions, and a foundation built to scale with every product you deliver.

THE BRIDGE

One connection.
From component to cloud.

Before a product can be digital, it needs a bridge. Edge-to-Cloud is that bridge: it takes data from the component or vehicle, processes what needs to happen locally at the edge, and securely delivers it to the cloud — where it becomes visibility, automation, and new services.

01 · Source

Component / Vehicle

Sensors, ECUs, and actuators generating raw data at the source.

02 · Edge

Local processing before anything leaves the device.
Faster decisions, less bandwidth, more resilience.

MARKET PRESSURE

Why product digitalization
can't wait.

1

Products don't end at launch

Real market validation happens in the field. Without connectivity, you can't see what's happening or fix it remotely.

2

Obsolescence is a business risk

A product that can't update remotely becomes a liability the moment a vulnerability appears.

3

Data is the new differentiator

Connected products that turn data into services outcompete ones that stay silent after the sale.

4

Compliance is now mandatory

The EU Cyber Resilience Act makes security-by-design and secure updates a market-entry condition — CRA-aligned from day one, not bolted on after.

Quick Answers

Short, direct answers to the most common questions about vehicle telematics, V2X, and connected mobility platforms.

What is V2X connectivity and why does it matter for vehicle OEMs?

V2X (vehicle-to-everything) is a communication framework that enables vehicles to exchange data with other vehicles (V2V), road infrastructure (V2I), networks (V2N), and pedestrians (V2P). For OEMs, V2X is critical for advanced safety systems, traffic efficiency, and autonomous driving readiness — and requires both embedded hardware integration and robust cybersecurity.

What telematics solutions exist for motorcycles and 2-wheelers?

Motorcycle and 2-wheeler telematics requires purpose-built solutions due to the constraints of two-wheel platforms: limited power, smaller form factor, and different sensor profiles than cars. OTC Engineering delivers end-to-end telematics for powered two-wheelers — from embedded TCU design to cloud platform and rider-facing mobile apps — with proven deployments for major motorcycle OEMs.

What is a vehicle telematics platform?

A vehicle telematics platform is a system that collects, transmits, and processes data from connected vehicles in real time. It combines embedded hardware (TCUs, OBD devices), connectivity protocols (MQTT, 4G/5G), and cloud infrastructure to enable remote diagnostics, OTA updates, fleet monitoring, and data-driven services for OEMs, fleet operators, and end users.

What is a connected car PaaS?

A connected car PaaS (Platform as a Service) provides OEMs with a ready-made infrastructure to connect vehicles to the cloud, manage device fleets, deliver OTA updates, and build digital services — without building the platform from scratch. OTC Engineering's i-ConnDrive is a connected car PaaS that adds a data-driven business layer and digital services marketplace on top of the connectivity infrastructure.

What is vehicle IoT (vIoT)?

Vehicle IoT (vIoT) refers to the application of IoT principles to connected vehicle systems — embedding sensors, gateways, and communication modules into vehicles to stream operational data to cloud platforms. Unlike generic IoT, vIoT must meet automotive-grade standards (ISO 26262, UNECE R156) and handle the unique constraints of in-vehicle networks such as CAN bus and AUTOSAR middleware.

How does OTC Engineering's ConnecTech platform work?

ConnecTech is OTC Engineering's end-to-end connectivity technology that links vehicles to the cloud and mobile apps in real time. It integrates IoT platform components, data treatment algorithms, and customer-facing digital services across multiple layers — from the in-vehicle device to B2C apps and B2B fleet dashboards. It is designed for OEMs who want to deploy connected services without building the full stack internally.

What is the difference between FOTA and Edge-to-Cloud updates?

FOTA (Firmware Over-the-Air) refers specifically to remote firmware updates for embedded devices in a vehicle. Edge-to-Cloud (Edge2Cloud) is a broader architecture where an edge gateway aggregates and buffers data locally before syncing to the cloud — enabling updates and data transfers even in environments with intermittent connectivity, such as off-road or industrial vehicles. UNECE R156 compliance governs both for type-approved vehicles.
