This marks KPMG's fourth cybersecurity company acquisition in five months.
First Point Global specialises in identity and access management (IAM). Founding partners John Havers and Jan Zeilinga will join KPMG's Cyber Security leadership team and bring 30 professionals with them, making up the largest specialist IAM team in the country.
The combined team will be known as KPMG First Point Global, and offer clients a full spectrum of cyberservices spanning consulting, systems implementation and ongoing support.
"This acquisition deepens our cybercapability in Australia, and is a very smart fit for growing client needs and our firm," KPMG Australia CEO, Gary Wingrove, said.
Globally, KPMG has identified cybersecurity as one of six strategic growth initiatives for focused investment.
In the past five months, KPMG's acquisitions included identity and access management consultancy, Qubera operating in USA, UK and India; Frankfurt-based security boutique consultancy P3 Consulting; and most recently Finnish cybersecurity business, Trusteq Oy -- which also specialises in identity and access management services and security transformation.
According to John Havers, CEO of First Point Global, digital identity and access management have risen in visibility within the corporate hierarchy.
"Ten years ago, we were having discussions with technologists about authentication and authorisation. Our discipline then became important for audit, risk and finance to address growing compliance requirements," Havers, said. "Today, digital identity and its management underpins customer-facing services which are strategic for the growth and survival of businesses, and C-level executives and boards care about that."
