In a blog post, the company said managed security services, threat detection and response services, and data security and privacy solutions would all attract higher spending.
Security services revenue in Australia was forecast to reach $5.5 billion by 2024. For New Zealand, spending was set to grow from NZ$464 million (A$427.8 million) in 2019 to NZ$821 million in 2024.
The forecast represented a five-year compound annual growth rate of 12.3%, IDC said.
Emily Lynch, A/NZ Associate Market Analyst for IT Services and author of IDC Australia/New Zealand's recently released Impact of COVID-19 and Future of Trust on Australia and New Zealand Managed Security Services report, said: "COVID-19 has changed security priorities significantly, and managed security services in A/NZ are set to benefit.
IDC said the new methods of working increased the need for network security, identity access management and software-defined WAN solutions.
"Many A/NZ organisations intend to invest in specialist managed security services providers to help them navigate new ways of working at scale and improve their threat detection and response capabilities," said Lynch.
"These investments enhance an organisation's security posture and demonstrate a commitment to growing trust in their partners and ecosystems."
