US cyber security company ReliaQuest has opened its first office location outside of the US in Leopardstown in Dublin.
ReliaQuest plans to create 100 jobs in the new Dublin office over the next three years.
The company said the new positions will see jobs for security engineers, analysts and content developers.
Founded in 2007, ReliaQuest employs over 300 staff across its three office locations in Tampa in Florida; Las Vegas in Nevada and now in Dublin.
"We chose Dublin for several reasons, including its strong talent, the ease of travel back and forth from our headquarters in the US and around the rest of Europe, and the openness and focus on collaboration fostered by Ireland," the company's chief executive Brian Murphy said.
"All of these things make Dublin a great place to be," he added.
The new jobs at ReliaQuest are being supported by IDA Ireland.
IDA Ireland chief executive Martin Shanahan said that Ireland has become a significant base of international technology and security companies thanks to a growing, well-educated and flexible workforce with a rapidly increasing graduate output.
"As a committed member of the EU, overseas companies increasingly look to Ireland as a base from which to serve its customers in the region," he added.
