About

James Turner is the founder and Managing Director of CISO Lens. Since 2005, James has specialised as a security industry analyst and advisor; facilitating roundtable discussions, conducting primary research, and producing reports that provide evidence-based decision support.

Before creating CISO Lens, James was an Advisor at local advisory firm, IBRS. During his 11 years with IBRS, James authored over 100 advisory notes for clients, presented at all the major security conferences in Australia, and facilitated dozens of executive roundtables. 

From 2013 to 2016, James was the appointed Chair of the Advocacy Group and an authorised spokesperson for the Australian Information Security Association (AISA). This volunteer work entailed providing public commentary on various security issues and helping raise the profile of AISA. 

In 2019, James was designated an AustCyber AllStar in recognition for his years of supporting and advocating the Australian security industry, as well as for the publication of the CISO Lens Benchmark, which AustCyber stated was a globally unique resource.

James still writes occasional opinion pieces for the Australian Financial Review, providing commentary on cyber security matters, and is one of the most experienced facilitators of security executive discussions in the region. 

As Country Manager for New Zealand, Nadia is integral to the ongoing mission of CISO Lens: to support the resilience of the region through enabling better cyber security governance. 

Nadia coordinates community collaboration, facilitates executive roundtables, conducts interviews, and gathers information from across the CISO Lens community, as well as helping to direct the CISO Lens research agenda. 

Before joining CISO Lens at the start of 2022, Nadia was the Manager for Incident Response at CERT NZ, where she ran a team of technical specialists that supported New Zealanders - individuals and organisations through any cyber security issue they were experiencing. 

As an authorised spokesperson for CERT NZ, Nadia frequently spoke to media about current issues and provided pragmatic advice to the public. Nadia also regularly briefed Ministers on current online issues, and regularly represented CERT NZ domestically and internationally.  

Nadia has both led and supported the New Zealand Government’s incident coordination and response to a range of incidents over the past ten years.

Nadia brings to CISO Lens a decade of experience in government, as well as a Master’s degree in Politics and International Relations.
