A cyber security software company is to create 150 jobs.
Cylance, which develops artificial intelligence to prevent rather than just detect threats and malware, is to open a new office on the South Mall in Cork city.
Chief executive Stuart McClure said: "Cork has become an international cyber security and technology centre, and we are proud to be a part of that."
The investment is supported by the Department of Jobs, Enterprise and Innovation through IDA Ireland.
Jobs Minister Mary Mitchell O'Connor said: " We are all aware of the crucial importance of being able to deal with cyber security threats and it is terrific news that a company of the stature of Cylance has decided to locate here."
Cylance is to hire staff over the next three years including in sales, sales engineering and customer support and malware analysis and software development roles further down the line.
