Phishing a concern for four in 10 firms
More than four in 10 companies surveyed from more than 130 countries around the world cited phishing as a top cyber security threat.
Phishing is an attempt to secure sensitive information such as names and passwords by posing as a trustworthy source.
Some 43pc of large businesses that took part in the Global State of Information Security Survey 2017 from consultancy PwC cited phishing as a threat.
Firms in 133 countries took part in the survey.
More than half of companies said employee training remains a top priority for data privacy.
The survey also found that many businesses are turning to advanced authentication technologies to add an extra layer of security and improve trust among customers, with over half (57pc) of survey respondents using biometrics for authentication.
Pat Moran, PwC Ireland cybersecurity leader, said the global findings were relevant to Ireland.
"From my experience of working with clients in Ireland, the global survey findings are very relevant and are very well aligned," he said.
"Clients are investing in security to provide them with a competitive advantage.
"I see more confidence from clients in leveraging from cloud-based technologies to identify cyber threats."
