Security test cases for ECUs, written by AI
Our AI connects to the real ECU through a Raspberry Pi and writes security test cases for what it finds there. Your engineer stays in charge the whole way.

Runs on the real ECU, on your test bench
The ECU never leaves your lab
No new rig: a Raspberry Pi and the adapter for your ECU
01
Wire a VSEC Bench, a Raspberry Pi flashed with the image VSEC generates, to the ECU on your test bench. It comes online in about 10 minutes, and the ECU stays where it is.
02
Through the Bench, the AI runs discovery, finds the diagnostic servers that accept input and reads the bus speed. Then it tells your engineer what it found, including any trouble with the test bench itself.
03
The AI writes test cases for the services it found, such as attempts to get past diagnostic security access, runs them and reports the results. Your engineer reviews each one and keeps the ones worth re-running on every new software build.
No. It works inside your engineer's session, not on its own. Within that session it runs discovery, writes test cases, runs them and reports what it sees, including problems with the setup: in one run, it flagged frame errors while the bus was down. We believe an engineer should own every test plan, so your engineer reviews what the AI wrote and decides which test cases to keep.

What hardware do we need?
A Raspberry Pi 3, 4 or 5 (a 4 or 5 with 4 GB of RAM or more is recommended), flashed with the image VSEC generates, plus the adapter for your ECU's interface, such as a CAN (Controller Area Network) adapter. The ECU stays powered on your own test bench. We sell no hardware.
Do we need a security specialist on the team?
Not to start. The AI draws on our own automotive protocol specifications, and your engineer brings what they know about the ECU. If you'd like an expert to look at a finding, our testers can reach the same Bench remotely.
