Gillmore Security Systems Inc. has earned a quality reputation over the past three decades by successfully protecting large, mid-sized and small family-owned businesses throughout Northeast Ohio. At Gillmore Security we provide our business security clients with unparalleled consultation, installation, training, monitoring and service for a variety of security system solutions including: access control, intrusion detection, fire systems, digital video systems, environmental monitoring and back-up systems.

The Gillmore family was involved with the construction of many of Cleveland's landmark buildings dating from the early 1900s. In 1971, Alan H Gillmore Jr. founded Gillmore Security Systems upon the premise that our organization would be the best in our field. This is still the driving value in our business today. Whether guarding homes from intruders, carbon monoxide or fires, distinguished homeowners have relied on Gillmore Security since 1971 to provide quality service and peace of mind. Gillmore Security Systems' service department is legendary in the industry.
