We help providers with the following key objectives:

What Makes Us Different
Skadi Solutions is Australia’s first independent enterprise-focused cyber security firm dedicated to Critical Infrastructure.
As targeted threats and increasing regulation put greater pressure on CI asset owners, many IT-focused providers are expanding into the OT security space. Additionally, a growing number of OT security firms have emerged, positioning themselves as domain-specific experts aiming to fill the gap.
However, few truly understand the complex, interconnected nature of both domains.
The reality is that true resilience demands an enterprise-wide security approach that spans both digital and OT business functions. At Skadi Solutions, we meet this need with sector-specific expertise and a suite of carefully crafted cyber security designed to enable organisations to take systematic steps toward enterprise-wide resilience.
In a sector clouded by fear, uncertainty, and doubt, Skadi Solutions brings the focus back to principled cyber security controls, proven to deliver value to IT and OT professionals alike.
The name, Skadi Solutions, is derived from the Norse goddess Skaði, a symbol for strength, agility, and adaptability. Just as Skaði thrives in the harshest environments, we empower our customers to embrace resilience amid an ever-increasing number of cyber security threats.
Built on the foundations of Australia’s foremost cyber resilience initiative for Critical Infrastructure
Skadi Solutions was founded in 2024 by Daniel Castillo, a rising star and influential voice gaining prominence in Australia’s IT/OT cyber security community. With a background in Mechatronics engineering, Daniel has over 8 years of hands-on experience in industrial automation solutions and enterprise cybersecurity across industries such as energy, councils, data centers, corrections, healthcare, mining, airports, commercial real estate, and more.
Former OT cyber security specialist within the Australian Government’s Critical Infrastructure Uplift Program (CI-UP), Daniel worked alongside some of the nation’s top cyber security experts to improve the resilience of Australia’s most vital CI providers. He remains focused on the mission, demonstrating that cyber resilience is achievable and accessible for CI providers big and small.
A passionate community leader, Daniel shares his expertise at industry forums such as the Realms of Cyber, Engineer’s Australia, and is an active board member for the International Society of Automation (ISA). Under his leadership, Skadi Solutions is setting new benchmarks for cyber resilience in critical infrastructure, enabling businesses to confidently address evolving threats.
