Why MSI?

MSI provides security systems, telecommunications, and cabling services to organizations in Spartanburg, Greenville, and surrounding areas in Upstate South Carolina. We specialize in hospitals, school systems, and commercial and industrial facilities.

MSI was founded in 1972 and came to the Upstate area in 1993. Since that time, most of our business has come through extensive referrals. Our satisfied clients appreciate the quality of our service and are eager to pass our name along to others.

What makes MSI different?

Customer Service

Anyone can sell you a system. But to get someone to stand behind that system and make sure it really works for you long-term—that’s what sets MSI apart.

We are customer service-driven, and it shows. Our clients consistently comment on our high quality of service and how quickly we respond to their requests. We purposely keep our client list smaller than it could be, so that we can give them the support they need, when they need it.

Expert technicians

We don’t send technicians to your business to do something they have never been trained to do—and you’d be surprised how often this happens in our industry! Maybe that’s why we’re so often called on to re-install systems another company has unsuccessfully set up.

All of our technicians are experienced and equipped with state-of-the-art testing and diagnostic equipment—so we can quickly identify problems and provide you with a solution.

Dependability

We understand how important it is that your security system or voice & data network runs smoothly and doesn’t let you down. We use high-quality, nationally-recognized manufacturers and install components correctly the first time.

While other companies typically offer a 90-day warranty, we are so confident in the quality of our systems that we offer a 3-year warranty on all parts and labor—which is virtually unheard of in our industry.
