About 4walls
Turning Cyber Risk into something Leaders can actually use
Most cyber problems don’t start with hackers. They start with confusion. Too many dashboards, too many reports, too many “priorities.” 4walls exists to fix that—by giving leaders a clear, practical view of their cybersecurity in one place.
Where it all started
After two decades in IT and cybersecurity, Nik Devidas kept seeing the same issue. Leaders didn’t lack commitment. They lacked clarity.
- Reporting was messy.
- Compliance was scattered.
- Staff training was inconsistent.
Everyone cared about cyber risk, yet no one had a simple way to manage it. 4walls began as a response to that gap. A platform designed to make cyber resilience understandable, trackable, and achievable—no technical dictionary required.

Meet the Founder: Nik Devidas
Nik has spent more than 20 years helping organisations strengthen their technology and security foundations. In 2003 he co-founded Rock IT, a managed services provider that later earned global rankings and was acquired in 2023.
He went on to found 4walls Cyber Advisory, building tools and programmes that simplify cyber risk for executives, boards, and leadership teams. Today he also serves as Group CEO of Axelo and sat government boards including Barwon Water Corporation and Barwon Asset Solutions.
Nik is known for turning complex risk into decisions leaders can act on. He speaks regularly on cybersecurity & AI governance, threat trends, insurance readiness, and the role of human behaviour in preventing breaches.
When people understand risk, they make better decisions.
That belief sits at the centre of 4walls.

Working with 4walls Cyber Advisory was an informative and enabling experience for Y Australia. From the outset, Nik’s expert approach was clear, supportive and underpinned by deep expertise in cyber security risk, with an appreciation for the unique features of our operating environment.
Nik took the time to understand our organisation and work with us in such a practical way, that it was an enjoyable and highly valuable experience for all involved, we confirmed what was working well and when we did identify areas of vulnerability, we were provided clear and tailored advice on how to strengthen our controls and resilience.
4walls Cyber Advisory approach the assessment process by creating an environment which promotes openness and transparency, all for the purpose of helping us improve and uplift our awareness, capabilities and preparedness.
The training provided was particularly welcomed by all, using real case studies, a highly visual, engaging and often fun look under the hood of how cyber controls can be breached. We all left the training with a heightened alertness to the risks and a greater appreciation for the vigilance we need to keep our organisation safe.
