Symantec said it will be looking for a “highly skilled, multilingual team to provide a Europe-wide sales and support function to its customers”.
It will create 200 jobs this year and a further 200 over the next two years.
Symantec has had a base in Ireland since 1991. Its base in Blanchardstown, Dublin, houses its security operations centre, as well as business authentication, software development and testing operations.
“These business units have played a crucial role in helping to protect businesses and consumers from increasing levels of cyber-crime,” a spokesman said.
“The European Customer Management Centre will be located alongside these existing functions.”
Taoiseach Enda Kenny said the decision by the technology giant, which employs 18,500 workers in more than 50 countries, to expand its Irish operation was a testimony to “our talented and flexible workforce”.
Matthew Ellard, Symantec’s vice president for Europe, the Middle East, and Africa, said the company was eager to continue its success in Ireland over the last 20 years of its presence here.
IDA chief executive Barry O’Leary said: “Symantec’s Irish operation is part of a global network that monitors cyber threats on a 24/7 basis.
“Symantec’s new EMEA Customer Management Centre will play an important role in the company’s global operations. Symantec is part of a thriving cluster of world leading security software companies operating in Ireland.”
ICT Ireland director Paul Sweetman said that, with more than 16,500 jobs announced in the last three years in the Irish technology sector, the focus must remain on ensuring that Irish workers have the right skills to meet the demand from high-tech companies.
“This must include a renewed emphasis on foreign language skills,” he said.
