Blume Corporation is a technology company that specializes in communications technologies, information technologies as well as security technologies. It is the company that developed and owns CTOS as well as its iterations, and is responsible for their operation, maintenance and advancement.

Through CTOS as well as its iterations, Blume Corporation has a borderline monopolistic power on digital information systems across the globe, as well as its subsidiaries and utilities.


Self-described as the "world's foremost innovator of high-tech, high-performance communications and security technology",[1] Blume Corporation specializes in everything from wireless phone operating systems, home computers, to digital imaging processors, and linked-by-network security systems. They take great pride in the fact that they helped create most of the markets they now dominate. Blume stands poised to reshape the way people think about Information Security Architecture (ISA).

Blume had its own security contractors in Watch Dogs to protect the company's major interests like CTOS Control Centers, Blume property, etc. These security members could be identified with CTOS signs on their gray uniforms. They were notorious for various criminal records of its members. In Watch Dogs 2, Blume hires Umeni Security Corps to provide security to their facilities. It is unknown if this was only for the Bay Area or if Umeni Security Corps were also contracted to replace Blume facilities in Chicago after the events of Watch Dogs.

Blume made many sketchy deals with organizations by giving them access to CTOS data and related technology like the Bellwether system, in exchange for funding and information. This in turn created one of the largest corrupt corporate monopolies that even included U.S. government agencies such as the FBI.
