In this episode of the Cyber Uncut podcast, host Liam Garman, editor of Cyber Daily, is joined by Kostas Siourthas, founder and CEO of TomorrowX; Rob Parker, partner at Deloitte; and cyber security leader Dr Marcus Thompson for an in-depth discussion on the future of data protection and innovation in the digital age.

In this episode of the Cyber Uncut podcast, host Liam Garman, editor of Cyber Daily, is joined by Kostas Siourthas, founder and CEO of TomorrowX; Rob Parker, partner at Deloitte; and cyber security leader Dr Marcus Thompson for an in-depth discussion on the future of data protection and innovation in the digital age.

The episode was recorded at Deloitte’s Sydney headquarters, where the panel explored how TomorrowX is reimagining cyber security by focusing on the movement and protection of data – rather than traditional infrastructure or application-centric models.

  • Siourthas unpacked how Tomorrow X’s data-centric platform enables organisations to apply security policies at the packet level and even add multifactor authentication to legacy systems – a task that was previously resource-heavy and complex.
  • Parker elaborates on the limitations of conventional network security in today’s encrypted world, and how TomorrowX’s composable, low-code architecture empowers business analysts to better manage data flows without relying on developers – reducing deployment timelines from months to weeks.
  • Thompson shares real-world context around legacy system risk, referencing the recent superannuation credential stuffing attacks, and outlines how TomorrowX provides a cost-effective pathway to modernise outdated systems without full replacement.
  • Finally, the trio reflect on what’s next for cyber security, why edge-case vulnerabilities remain one of the industry’s biggest risks, and why now is the time for proactive, data-first strategies.
