Where vehicle safety and cybersecurity converge
Modern cars run on software across many electronic control units (ECUs), connected to mobile apps, charging stations, and the cloud. Each connection can be attacked. We test every part of the vehicle and help you meet cybersecurity standards.

Vehicle cybersecurity is no longer optional.
A successful attack can affect a moving vehicle, not just data. Which is why, to get a vehicle on the road, you now need evidence-backed security.
How we secure it
We identify and test every connected entry point, from the in-car electronics to the cloud, so weaknesses are found and fixed.
Complete mapping of every connected entry point, with threat modelling
Coverage that keeps up as your fleet and features grow
How we contain it
Safety-aware testing that pushes on critical functions without putting a person or a production line at risk.
Testing based on our OT and ICS experience
Ranked by physical blast radius, not just CVSS
How we get you through
We turn testing into audit-ready evidence mapped to each work-product. Compliance you can hand over, not just claim.
CSMS and SUMS gap assessment and TARA

01 Attack Surface
More connections mean more ways in
Every connected feature, software updates, telematics, charging, the mobile app, the fleet backend, adds another way in, not just from the car.

02 Safety-Critical Exposure
A breach here doesn't leak. It moves.
An IT incident costs a bad week. An automotive incident can touch braking, steering, and a vehicle that stays on the road forever

03 Regulation
Proving your vehicles are secure is mandatory
ISO 21434, UNECE R155 and R156, and regional mandates decide market access. Recognising them is not the same as proving them, and only proof clears the gate.

What We Deliver
One Partner for Every Part of Automotive Security
Whether you need to test a single component, a charging network, or get ready for full R155 approval, there is a Payatu service for it.
Red teaming for connected vehicles and charging
We simulate a real attack to see how far an attacker could actually get.
EV charging security
We test EV charging end-to-end. Everything from chargers to backend systems is tested.
ISO 21434 and UNECE R155/R156 compliance
Gap assessment, risk analysis, and getting you ready for approval.
Telematics and connectivity security
We test the wireless links: Bluetooth, Wi-Fi, cellular, and V2X.
Compliance
Compliance – proven the right way
We don't check boxes. We show what an attacker could do, then write it up as evidence an assessor accepts.
Standard
What it requires
How Payatu helps
The standard for building cybersecurity into a vehicle across its whole life, including TARA
We run TARA workshops, security testing, and provide evidence.
Requires an approved CSMS before a vehicle type can be sold.
We assess your CSMS for gaps, validate, and prepare you for the audit.
Requires a Software Update Management System.
We review and harden the security of your update system.
Cybersecurity best practices for vehicles (US) and organisation-level security controls.
We review you against NHTSA guidance and NIST 800-53 controls.
