High Security Solutions for Every Market

For centuries, Sargent and Greenleaf has partnered with individuals, corporations and government entities worldwide to provide innovative, quality-driven security solutions to protect what's most important. Wherever the highest security is needed—banks, cash-in-transit, retail outlets, homes, utilities or government spaces—you will likely find a S&G lock or security solution protecting the contents. S&G has been the go-to resource for securing the most sensitive environments and valuables since the U.S. Treasury first adopted James Sargent's Magnetic Bank Lock as its standard in 1860. That legacy of innovative security continues today.
