The firm behind the business that was victim to a “very sophisticated cyber attack” in 2013 is to maintain its presence here, but with a reduced workforce.

The managing director of Loyaltybuild confirmed yesterday that a "very sophisticated cyber attack" 14 months ago cost the firm millions of euro in lost revenues.

Pre-tax profits at Co Clare- based customer loyalty rewards firm, Loyaltybuild decreased by 7% last year to €4m in spite of an increase in revenues.
