Enator corporation started in 1977 as a consultant firm created to support the Pronator company with software and project management.

The subsidiary's name, Enator, was applied to the whole group in 1995 when Celsius AB, a publicly traded Swedish company, merged the IT operations it had acquired between 1991 and 1994.

[42] On 25 November 2011,[43] there was a hardware failure in one of Tieto's Swedish data centers, which affected approximately 50 of its clients, including Apoteket (a national pharmaceuticals retail firm, for whom e-prescriptions were out of service), Bilprovningen (a Swedish motor vehicle inspection firm, which was forced to perform inspections with manual support), SBAB Bank and the Stockholm Municipality school web site.

[44][45] Kristina Westerlind, Head of Marketing and Communications at Tieto Sweden, commented on the incident to Dagens Nyheter: "It is a hardware failure that is very difficult to predict at this time how long it takes to restore everything to normal.
