Hi, I’m Vladimir - welcome to my personal site!

Vladimir Jirasek headshot

Thanks for visiting! With over 30 years’ experience in technology and cybersecurity, I’ve had the privilege of working with amazing teams and organisations across the globe. From guiding businesses through complex transformations to ensuring their digital strategies are secure and future-ready, I’m passionate about helping people and companies thrive in an ever-changing world.

What I Do

I specialise in bridging the gap between technology and business. Whether you’re looking for strategic advice, need a seasoned expert as a part-time CTO or CISO, or want an engaging speaker for your next event, I’m here to help.

Here’s how I can support you:

  • Strategic Advice: Helping leaders and boards make confident decisions about IT, cybersecurity, and digital transformation.
  • Fractional Roles: Offering my expertise as a part-time CTO or CISO to drive innovation and security without long-term commitments.
  • Speaking & Workshops: Sharing insights and practical advice at events, conferences, or tailored sessions.

A Bit About Me

I’ve worked with some of the world’s most respected organisations, from government bodies to global tech companies. I love tackling challenges, bringing fresh perspectives, and ensuring technology works for people—not the other way around.

When I’m not immersed in tech and strategy, you’ll likely find me sharing ideas with brilliant minds, mentoring future leaders, or enjoying quality time with my family.

Professional bio

I have extensive knowledge and experience in cybersecurity, information technology, and digital transformation. I use my expertise to ensure that businesses closely align their technology stack with their business strategies. My colleagues, clients, and senior executives, such as CIOs and CTOs, acknowledge my technical and business acumen in advancing cybersecurity within their diverse business supporting technologies, including IT, cloud, data, and server architectures.

These skills helped me start two cybersecurity companies that design and build cybersecurity solutions for a wide range of businesses. The companies have successfully provided a diverse range of cyber services to financial institutions, national critical infrastructure agencies, manufacturing, and R&D enterprises. This particular activity helps me realise my dream of being a prime mover in the information technology discipline.

Opportunities to share my experience within the information security field include presenting at conferences, authoring cybersecurity articles, and editing information security publications. Moreover, these endeavours underpin a strongly held conviction that nurturing young talent to become the next generation of experts is the best way to retain a thriving industry.
