Economic Moat
Iron Mountain possesses a formidable economic moat characterized by exceptionally high customer switching costs, as physically relocating millions of boxes of legacy records is logistically complex and prohibitively expensive. This is reinforced by a massive, irreplaceable global real estate footprint and a trusted brand reputation built over seven decades of meeting strict regulatory compliance standards.
