Eleven hardware bugs on one physical board.
DVRPi is a hardware training platform designed, built and sold by Exploit Security for security teams, training providers and product companies that need real embedded attack surface to practise on, not a VM with a web login.

Training and custom CTFs
Need the same approach pointed at your own product? We build custom labs different hardware, your product’s bus, a week-long internal CTF as a scoped engagement.
Why we built it
Most “IoT labs” are a VM and a web login. Real devices fail on the header row: UART left live, U-Boot unlocked, SPI dumps, BLE leaking, audio in-band.
We built DVRPi as a physical board with those classes of bug designed in eleven challenges, each mapped to a real-world failure.
We use it to train client teams, and we sell it to organisations that want the same hardware on their own bench.
