Focus on Small to Medium Businesses (SMBs)

While our expertise spans multiple sectors, including financial services, Australian State and Federal Government agencies, and security services and products, our primary focus is on SMBs (< or = AUD$250m revenue per annum). We aim to provide SMBs with the security expertise and advice that larger corporations and governments have ready access to. However, we stand ready to support any client that requires our expertise.


Addressing Growing Security Obligations

With increasing security-related obligations—such as privacy, critical infrastructure, directors’ responsibilities under corporations law, and the Cyber Security Act passed on 25 November 2024—SMBs must be aware of their security posture and mature their capabilities. This is crucial not only to meet obligations but to enable businesses to operate and grow safely.


Expertise and Tailored Solutions

Theo's 23-year pedigree in Australian and global financial services, combined with consulting for the Victorian Government, energy sectors, and the Australian Government since 2022, ensures that our tailored solutions meet the specific needs and compliance requirements of our clients.

Holistic and Tailored Solutions: We begin with a comprehensive assessment of your current security posture, followed by a detailed roadmap to enhance your defences.


Contextualised Communication: We avoid baffling our clients with technical jargon. Instead, we tailor our explanations to specific managerial and executive responsibilities, ensuring that updates, rationales, findings, metrics, and reports are crystal clear.


Wide Range of Services: Our solutions include everything from threat intelligence and incident response to compliance management and security training.


Business-Feasible Security: Our goal is to build practical security measures that enable our clients to safely deliver products and services, while adapting to the evolving threat landscape.


Clear Explanations: Theo's passion for explaining complex technical concepts in plain, layperson’s English ensures that our clients fully understand their security posture and the necessary steps to improve it.

Certified Professionals: Our team comprises highly experienced professionals with certifications such as CISSP, CISM, and CRISC.


Leadership: Theo Nassiokas, Founder and Principal Consultant of Let’s Go Cyber, and Co-Founder and President of Cyber8Lab Australia and Cyber8Lab Malaysia, is a former member of the Australian Government's Senior Executive Service (SES) at the Australian Taxation Office (ATO) as Assistant Commissioner, Cyber Governance. He led a branch of 120, delivering comprehensive cybersecurity governance, risk & compliance (GRC) solutions.


Industry Experience: Theo has held several senior leadership roles in financial services, including Director, APAC Cyber & Information Security (CISO) at Barclays Singapore, and Head of Business Controls & Monitoring, Group Technology at Westpac Group.
