Tyco International, Inc.

Tyco International plc, now operating primarily as Johnson Controls, no longer exists as a standalone entity with "Security and Compliance" as its main function in the way it once did. A significant restructuring and acquisition history has resulted in its security-related businesses being integrated into other companies.

Originally, Tyco International was a large conglomerate with diverse holdings. Its security segment was a substantial part of its operations, encompassing various security products and services. This included fire protection, intrusion detection, video surveillance, and access control systems. The company had a strong presence in both the commercial and residential markets, offering solutions for a wide range of clients. Tyco's security business operated on a global scale, with facilities and operations in numerous countries. It was known for its brand names like ADT (which was spun off later), and other security technology brands that may now reside under different corporate umbrellas.
