About MSSI

MSSI Company Overview

Modular security systems

The company’s patented Modular Access Control (MAC) Portal is a standard, practical, sturdy structure made from industrial grade materials. Unused, but not useless. While some businesses are built on thinking outside the box, MSSI’s business is built on reinventing the box; that is, taking what others see as a single-use container and reconfiguring it and giving it multiple, pragmatic purposes for contractors the world over.
