Regulatory frameworks

Every engagement is mapped to the frameworks that matter most in this industry — so each finding directly supports your compliance posture.

UN Regulation No. 155
mandatory Cybersecurity Management System (CSMS) certification for vehicle type approval; applies across the lifecycle from design to decommissioning
UN Regulation No. 156
Software Update Management System (SUMS) required for homologation of vehicles with software updates, including OTA
ISO/SAE 21434
automotive cybersecurity engineering standard covering TARA, security concept, verification, validation, and post-production monitoring activities
ISO 24089
software update engineering for road vehicles, the SUMS companion standard to R156
NIS2 Directive (EU 2022/2555)
applies to large automotive manufacturers and critical component suppliers as important entities
GDPR
protection of vehicle-generated personal data (location, driving behavior, biometrics) collected via telematics and connected services
Methodology

Testing methodology

A tested, repeatable approach covering every layer of the modern environment relevant to this industry.

01 · PHASE

In-vehicle bus testing

CAN, CAN-FD, LIN, FlexRay, and Automotive Ethernet fuzzing, replay, and injection against gateways, body controllers, and ADAS ECUs

02 · PHASE

ECU & firmware security assessment

hardware extraction (JTAG, SWD, SPI), binary analysis, secure-boot bypass attempts, and SBOM review

03 · PHASE

Telematics & connected-vehicle cloud testing

TCU modem security, backend APIs, mobile digital-key apps, and authentication of OTA channels

04 · PHASE

OTA & update-chain security

signing, integrity checks, rollback protection, and post-deployment attestation across the full SUMS flow

05 · PHASE

Wireless-interface testing

Bluetooth, BLE, Wi-Fi, cellular, UWB, and passive-entry/keyless-go relay attacks against the vehicle and key fobs

06 · PHASE

TARA & CSMS / SUMS audit

gap analysis against ISO/SAE 21434, UN R155/R156, and ISO 24089 requirements for type-approval readiness

Services

Key services

Targeted services for the most common security needs in this industry.

Threat landscape

Threats facing this sector today

Every security engagement is scoped based on the attack patterns that actually hit this sector — not a generic checklist.

In-vehicle bus attacks

CAN, LIN, FlexRay, and Automotive Ethernet injection, replay, and fuzzing attacks against safety-critical ECUs.

Keyless-entry relay attacks

Relay, roll-jam, and range extension attacks that unlock and start vehicles without the physical key.

Telematics-cloud compromise

Attacks against TCU modems, connected-vehicle backends, and mobile digital-key apps.

Malicious OTA updates

Signing-chain weaknesses or rollback failures that allow malicious firmware to reach the vehicle.

Supplier compromise

Tier-1 and tier-2 supplier breaches that inject vulnerable or backdoored components into the vehicle BOM.

Driver data exposure

Leakage of location, driving behavior, and biometric data collected by the vehicle and connected services.
