About SEM

In 1967, Security Engineered Machinery Co., Inc. (SEM) was established by Korean War veteran, Leonard Rosen. Today, SEM stands as a US manufacturer that provides comprehensive end-of-life solutions for the protection of sensitive information in government and commercial markets. SEM data destruction devices are the premier high security choice available on the market today.

Whether paper, hard disk or solid state drives, tape, microchips, or any other type of media-bearing device, SEM has a solution that can sanitize classified and top secret information as well as controlled unclassified information (CUI), personally identifiable information (PII), personal health information (PHI), or any other type of sensitive data. SEM also produces customized equipment for size reduction solutions and for destroying off-spec or returned product for the medical device, gaming, security printing, and food industries as well as bank note/currency destruction for the US Federal Reserve and Central Banks throughout the world.

Primary products include personal, departmental, and central destruction paper shredders, hard drive shredders and crushers, solid state device shredders and disintegrators, magnetic media degaussers, and optical media shredders and destroyers. In addition, as the inventor of the disintegrator in 1967, SEM continues to offer and service a complete line of disintegration systems designed for an office environment as well as larger centrally located systems for heavy duty, high-volume applications that are supported by a variety of customized waste collection systems including briquetting for paper, which creates a 100% recyclable end product and contributes to LEED points in new construction.

SEM has established a global reputation for quality, reliability, and customer service. Our sales and service departments are always accessible, and clients appreciate the high quality solutions and custom, dedicated technical support we are able to provide as a small business and US manufacturer. When it comes to a solution to securely and effectively eliminate end-of-life information or mitigate liabilities, SEM still stands as the first choice of the US Federal Government and security-focused Fortune 50 companies.

A History of Innovation and Excellence

On January 23, 1968, the USS Pueblo, a Navy intelligence vessel, was engaged in a routine surveillance of the North Korean coast when it was intercepted by North Korean patrol boats. According to U.S. reports, the Pueblo was in international waters almost 16 miles from shore, but the North Koreans turned their guns on the lightly armed vessel and demanded its surrender. The Americans attempted to escape, and the North Koreans opened fire, wounding the commander and two others. With capture inevitable, the Americans stalled for time, destroying the classified information aboard while taking further fire. Unfortunately, the volume of material on board was so great that it was impossible to destroy it all prior to capture. An NSA report quotes Lieutenant Steve Harris, the officer in charge of Pueblo’s Naval Security Group Command detachment: “Only a small percentage of the total classified material aboard the ship was destroyed.”

Korean War Veteran Leonard Rosen was struck with the idea that there must be a better way to destroy classified information, and he began working to develop a faster, more efficient and secure method. Within weeks he had developed the concept for the world’s first paper disintegrator — and SEM was born.

For over 50 years, SEM has been the driving force behind document and data destruction innovations that are now considered industry best practices. From the world’s first disintegrator to the industry’s most successful line of electronic media crushers and shredders — and the only touchscreen, dual-voltage, NSA Listed degausser — SEM enjoys a reputation for innovation earned from a firm commitment to engineering, design, and product manufacturing.

Today, SEM provides comprehensive end-of-life solutions for the protection of sensitive information in government and commercial markets.

SEM’s reputation as the authority in high security information sanitization was earned through over 50 years of technical innovation, intellectual curiosity, and unrelenting integrity. By fostering a supportive, team-centric environment focused on talent retention and client satisfaction, SEM is recognized as the undisputed leader in depth of expertise, industry excellence, and reliability. SEM’s government clients include the CIA, FBI, all branches of the military, DoD, and NSA. SEM is also the leading supplier of information destruction equipment to Embassies worldwide. In addition, SEM’s commercial clients include three of the top five cloud infrastructure providers worldwide as well as numerous Fortune 50 companies.
