Unisys Corporation is an American multinational information technology (IT) services and consulting company founded in 1986 through the merger of Sperry and Burroughs.

The company provides digital workplace, cloud applications and infrastructure, enterprise computing, business process, AI technology, and data analytics services.

[6] Soon after the merger, the market for proprietary mainframe-class systems, the mainstream product of Unisys and its competitors such as IBM, began a long-term decline that continues, at a lesser rate, today.

[16] In June 2021, the company announced the acquisition of Unify Square,[17] which provides software and services which help enterprises manage collaboration and communication platforms like Zoom and Microsoft Teams.

[41] In November 2020, Unisys updated its Stealth platform to include visualization and dashboard tools to make it easier for an organization to track security in real-time.

[42] The new version made it possible for cybersecurity teams to see relationships between all network endpoints, including multiple clouds and edge computing platforms.

[42] Unisys was the first to develop a server architecture that supported four operating environments to run simultaneously on the same computer system in a single virtualized partition.

[46] Unisys’ partnerships include: Clients include Bank ABC,[56] Hershey,[56] the Bank of China,[57] Somos,[56] Henkel,[58] Flowserve,[59] The Philippine Statistics Authority (PSA),[60] MASkargo (the cargo division of Malaysia Airlines),[61] Nutreco,[62] California State University (CSU),[15] Air India,[63] RAMS Home Loans,[64] and the Georgia Technology Authority.

Additional projects include the following: A study sponsored by Unisys and conducted by IDC revealed the gap between the activities and expectations of the new generation of "iWorkers" and the ability of organizations to support their needs.

[65] The results showed that organizations continue to work with standardized command and control IT models of the past and are not able to profit from the widespread use of newer networked technologies.

[citation needed] The contest allows students to explore the possibilities and complexities of cloud computing in areas such as automation, virtualization, application development, security, consumerization of IT and airports.

[68] It is a “comprehensive benchmarking tool to measure disability workplace inclusion.”[68] In November 2021, Unisys launched its UGrow program to help its employees grow internally.

[79] In 1998, Unisys Corporation agreed to pay the government $2.25 million to settle allegations that it supplied refurbished, rather than new, computer materials to several federal agencies in violation of the terms of its contract.

Unisys admitted to supplying re-worked or refurbished computer components to various civilian and military agencies in the early 1990s, when the contract required the company to provide new equipment.

In 1998, Unisys was found guilty of price inflation and government contract fraud, with the company settling to avoid further prosecution.

[82] In 2006, The Washington Post reported that the FBI was investigating Unisys for alleged cybersecurity lapses under the company's contract with the U.S. Department of Homeland Security.

Visible Systems appealed the final judgment, believing the court wrongly excluded the issues of bad faith and disgorgement of an estimated $17 billion in unjust profits from the consideration of the jury.

According to the 2012 verdict of the Labour Court of Budapest, Unisys acted illegally and was ordered to pay unpaid wages and benefits, legal costs, and three months' average salary as compensation.
