Comprehensive cybersecurity services

Cybersecurity Advisory and Assistance

Our consultants provide expert advice and practical support to help you protect critical assets and meet your security and compliance objectives.

From strategy and policy development to compliance uplift and incident readiness, our work is guided by deep knowledge of government frameworks and the evolving threat landscape.

Vulnerability and Penetration Testing

We identify and address vulnerabilities before they can be exploited.

Using OWASP methodologies and aligning with the Australian Government’s Protective Security Policy Framework (PSPF) and Information Security Manual (ISM), we assess your systems, networks, and applications to uncover weaknesses and strengthen defences.

Our reports deliver clear, prioritised recommendations so you can act with confidence.

Cyber Risk Assessments

Understand your current security posture and the risks that matter most.

We evaluate your cyber resilience across infrastructure, processes, and people,  helping you manage exposure and prioritise improvements.

Each assessment provides a clear roadmap to uplift your maturity and mitigate threats before they become incidents.

Essential Eight Readiness & Assessments

We specialise in helping organisations achieve and maintain alignment with the Australian Cyber Security Centre’s Essential Eight framework.

Our consultants – who have trained assessors and supported the ACSC directly – guide you through readiness, maturity uplift, and continuous improvement to reach your target Essential Eight maturity level.

IRAP Assessments

As one of Australia’s most experienced IRAP Assessors and Trainers, OneGUARD provides trusted assessment and advisory services for government systems and cloud service providers.

We help you navigate the PSPF, ISM, and IRAP frameworks efficiently and effectively, ensuring compliance and protecting classified and unclassified ICT systems up to SECRET.

Cybersecurity Training

Build the capability and confidence of your teams with targeted, expert-led training.


Our programs include Privileged User Training, Essential Eight training, and a one-day, hands-on IRAP Assessment Workshop designed to support newly endorsed ACSC IRAP assessors. Each course combines practical learning with real-world experience from seasoned professionals.
