De Rojas joins from McAfee, where she bolstered the firms position in the security market, and will look to expand CA's reach in her role as vice president and general manager UK and Ireland.
She worked at CA in the 1990s before going on to senior management roles at Novell, where she oversaw a reinvention of the vendor's channel, before her more recent stint in the security market. Marco Comastri, president CA Technologies EMEA, said that the 25 year industry track record of de Rojas made her the right candidate to take the company forward.
"She is, without doubt, well positioned to help CA Technologies in adding value to our UK and Ireland customers," he said.
He added that it was trying to change its relationship with customers, "as they look to move away from simply managing and maintaining IT to delivering business services".
