A lock nobody can see is a lock nobody can defeat.

VaultX designs and manufactures a U.S.-patented internal locking system that protects shipping containers and 53-foot van trailers against cargo theft across ocean, rail, and over-the-road transport.

Instead of bolting hardware to the outside of a door — where it signals value and invites a grinder — VaultX secures the doors from the inside and holds them shut under load. It installs in minutes with minimal modification, is configurable for tractor-trailer hinged and roller/rollup doors as well as ISO shipping containers, operates in cold-chain conditions, and is reusable trip after trip rather than cut off and discarded like a single-use seal. It's the most versatile lock ever made for the shipping industry — and to date, no VaultX lock has ever been defeated or broken into.

Prevention, not notification

There's a lot of great cargo-security technology out there — GPS trackers, sensors, smart seals — but nearly all of it tells you a load has already been broken into. That's evidence for a claim, not a load saved. VaultX is built to prevent the break-in in the first place. And because the majority of U.S. cargo theft happens while trailers and containers sit idle — in yards, drop lots, and unsecured parking — VaultX is designed to guard freight at rest, exactly where it's most exposed.

Built by the people who invented it

VaultX was invented by twin brothers Carlton and Frederick Martin, and works with carriers, shippers, intermodal operators, and logistics providers to cut cargo loss where it happens most — in transit and at rest.

Secure from within.
