Cybersecurity startup founder who has trained over 440,000 employees worldwide
Chantelle Ralevska is the Founder and CEO of a cybersecurity startup that delivers tailored security awareness training to businesses — an organisation that has trained more than 440,000 employees worldwide, working with some of Australia's largest and most complex organisations including Macquarie Group, Westpac and Woolworths. With women making up just 4% of cybersecurity startup founders, she occupies a rare position: a practitioner who has built genuine commercial scale in a field still dominated by men, and who has educated more than 500,000 viewers on YouTube by demystifying cybersecurity and career pathways.
Chantelle's distinctive contribution is framing cybersecurity not as a technical problem but as a cultural one — centred on awareness, resilience and behavioural change across entire organisations. Her work actively champions diversity in the sector, and she speaks to the intersection of AI and cybersecurity with the authority of someone building product in that space daily. She has presented at global cybersecurity conferences and is equally at home addressing C-suite executives as she is coaching small business owners on protecting themselves without specialist budgets.
Chantelle suits conferences in technology, financial services, professional services and sport — anywhere that data protection and human behaviour intersect. Her keynotes are practical and sector-specific, equipping audiences with a clearer understanding of where their real vulnerabilities lie and what to do about them.

Cybersecurity is often framed as a technical issue, but modern cyber attacks don’t start with technology failures. They start with human behaviour.
In this keynote, Chantelle Ralevska flips the traditional cybersecurity narrative. Drawing on real-world incidents, behavioural science, and frontline experience, she shows how cybercriminals manipulate trust, emotion, urgency and familiarity, and why even smart, capable people fall for attacks.
Rather than fear-based messaging or technical overwhelm, this session empowers audiences with clarity, confidence and a new understanding of their role in cyber defence.
Key Themes
* Why human error is the leading cause of cyber incidents
* How attackers exploit psychology
* Why “awareness training” often fails, and what actually changes behaviour
* The shift from compliance to culture
* What everyday people can do to reduce risk (at work and at home)
Audience Takeaways
* A clear understanding of how modern cyber attacks really happen
* The confidence to recognise manipulation tactics early
* Practical habits that reduce personal and organisational risk
* A sense of ownership and cybersecurity as everyone’s job
Cybersecurity is no longer an IT issue, it’s a leadership and governance responsibility.
This keynote is designed specifically for executives and decision-makers who are accountable for risk, reputation and resilience. Chantelle breaks down cyber risk in clear business language, cutting through technical jargon to focus on what leaders actually need to know.
She explores how leadership behaviour, culture and decision-making directly influence cyber outcomes, and why many organisations remain exposed despite heavy investment in technology.
Key Themes
* Why cyber incidents are now business-ending events, not IT disruptions
* Leadership blind spots when it comes to human risk
* What boards and executives are personally accountable for
* How culture, tone and visibility shape security outcomes
Audience Takeaways
* A clearer view of their role in managing cyber risk
* The right questions to ask security and technology teams
* Practical leadership actions that drive safer behaviour across teams
AI isn’t coming, it’s already here, and it’s changing cybersecurity faster than most organisations realise.
In this keynote, Chantelle explores how AI is reshaping the threat landscape on both sides: how employees are using AI tools at work, and how attackers are using AI to make scams more convincing, more personalised and harder to detect. This session demystifies AI risk without hype or fear, focusing on what’s actually happening now, and what organisations must do to stay ahead.
Key Themes
* AI data leaks: How everyday AI use can expose sensitive information
* AI hallucinations: Why AI confidently gives wrong answers, and the risk that creates
* AI-enhanced social engineering: Voice cloning, deepfakes and hyper-personalised scams
* Why traditional awareness training isn’t enough in an AI world
* How human judgement becomes more important, not less
*
Audience Takeaways
* A practical understanding of AI risks in plain language
* How to use AI safely without stifling innovation
* Red flags to watch for in AI-enabled scams
* Clear guidance on what individuals and leaders should do differently now
In this empowering keynote, cybersecurity founder and CEO Chantelle Ralevska shares her journey from senior roles inside some of Australia’s largest organisations to launching Psyber, a cybersecurity education company born from a clear gap she identified in the market.
In an industry where women make up a small minority of the workforce, and even fewer are founders, Chantelle offers a candid look at what it means to step up, be visible and lead in rooms where you are often the only woman. She explores how she built credibility, influence and confidence in a highly technical, male‑dominated sector, while backing her own judgment as a founder.
Chantelle highlights why representation matters and challenges narrow definitions of who “belongs” in tech, showing how diverse skills and backgrounds, from law to communications, can translate into successful careers in cyber and beyond.
Ideal for International Women’s Day events, women’s networks and leadership forums, this session blends lived experience with practical insight, offering an honest look at the challenges and opportunities facing women building careers and companies in male‑dominated industries.
Key Takeaways
- How to own your space and build credibility in male‑dominated environments
- The shift from employee to entrepreneur, and learning to trust your own judgment
- Why broadening pathways into tech strengthens teams, culture and capability
- The role of visibility in inspiring the next generation of women leaders
- Practical ways organisations can invest in women beyond a single calendar moment
