Why it matters
The business case for automotive security testing
Attackers don't wait for your next homologation cycle. Neither should your security testing.
- ISO/SAE 21434 & UNECE R155/R156 type approval requires independent testing evidence
- NIS2 & GB 44494 mandate third-party validation across the vehicle lifecycle
- Cyber insurers now require documented pen test results for OEMs and Tier 1s

Pain points we address
Sound familiar?
Design-time testing misses real attack paths
TARA and static analysis define what should be secure; adversarial testing proves what is.
Type approval needs independent evidence
Self-assessments do not satisfy type approval authorities.
OTA & backends grow the attack surface daily
Every release introduces new vectors that need continuous validation.
Unverified remediation
Protocol-level and cryptographic fixes need a controlled retest.
Boards need risk language
Raw scan output doesn't communicate regulatory exposure.
