With its global headquarters located in California, the corporation also has operations in the UK and Northern Ireland.
The company's core operations, including engineering, R&D, customer service, finance, and marketing, would initially be housed in the Cork city centre hub.
Currently, Proofpoint employs more than 4,500 people worldwide, with more than 100 of them workers based in Cork.
"We are delighted that Proofpoint has chosen Cork as the location for their new global hub," stated Peter Burke, Minister of Enterprise, Trade, and Employment.
This rise is evidence of Ireland's favourable business climate and our dedication to promoting innovation and development in the cybersecurity industry.
"The creation of over 250 jobs in the coming years is a significant boost for the region and highlights our ongoing efforts to support enterprise development and employment opportunities across the country," he stated.
In order to remain ahead of attackers' shifting methods, Proofpoint puts more than 20% of its income back into research and development, according to Rémi Thomas, Chief Financial Officer.
"Our expansion into Ireland is critical to our international growth, solidifying our ability to protect European organisations and our commitment to delivering innovative technology that addresses our customers' needs," he stated.
The CEO of IDA Ireland, Michael Lohan, expressed his excitement that Proofpoint had chosen Cork to serve as its new global base.
"This choice emphasises the critical importance of regional investment and showcases the South-West region’s established cybersecurity cluster and the abundant talent available regionally and indeed across the country," stated Mr. Lohan.
"The growth of Proofpoint enhances Ireland's standing as a top hub for international cybersecurity and compliance enterprises. We look forward to helping them develop and succeed in Cork going forward," he said.
