An IT security firm is to create 100 jobs at a new operations centre in Dublin.
Mandiant is opening a security and engineering centre to develop products to fight cyber attacks.
Jobs Minister Richard Bruton said: "Today's announcement that Mandiant, a specialist company in the fast-growing IT security sector, is establishing operations in Ireland with the creation of 100 high-end jobs is great news.
"We in Government will continue to build on Ireland's success in this area to create the jobs we need."
The Dublin facility will also serve as Mandiant's security operations centre and is looking to hire IT and security operations expertise.
The company is one of only four certified to respond to cyber attacks in Britain via the cyber incident response programme administered by the UK's Government Communications Headquarters (GCHQ).
Meanwhile, Energy Minister Pat Rabbitte announced the creation of 150 construction jobs as part of a wind energy project in Co Offaly.
A 140 million euro investment from Bord na Mona will see the building of 30 high-spec turbines at Mount Lucas. The turbines are expected to provide eco-friendly electricity for up to 50,000 households across the country.
Mr Rabbitte said when completed, Mount Lucas would contribute to the balance needed in Ireland's energy mix.
"The need to reduce our dependence on imported fossil fuels through exploitation of our renewable and efficiency resources has never been greater," the minister said. "Here in Ireland we have an abundance of renewable energy, with particular potential in the onshore wind sector, and it is vital that we continue to exploit this potential."
