Unisys has dismissed reports in the Washington Post that it was to blame for data breaches at the US Department for Homeland Security last year.
Unisys said, "The allegation that Unisys did not properly install essential security systems is incorrect. In addition, we routinely follow prescribed security protocols and have properly reported incidents to the customer in accordance with those protocols."
Unisys said, "We are proud of our work and believe it has significantly strengthened the integrity and performance of the agency's information infrastructure in the difficult years following September 11, 2001."
Unisys began providing security services to the DHS in 2003. The company has provided DHS with government-certified and accredited security programs and systems, which were in place when data breaches took place in 2006.
Those breaches came to light this year. The systems in question remain in place today, said Unisys.
Unisys said, "We believe that a proper investigation of this matter will conclude that Unisys acted in good faith to meet the customer's security requirements."
In the UK, Unisys has been slammed by the Unite union for planning to close its final salary pension scheme.
