Hi, I'm Izak,

And I want to help you!

I’m Izak Oosthuizen, a visionary London IT leader, bestselling author, entrepreneur, and cybersecurity expert. It might sound like a handful of roles, and indeed it is. But you know what? It’s everything I’ve ever dreamt of. 

Now, I’m on a mission to empower others to navigate the ever-evolving world of IT and cybersecurity. If that mission resonates with you, then keep on reading.

About me

Artificial Intelligence, the Fourth Industrial Revolution, and the Internet of Things – these are the buzzwords of our times. The enormous potential they offer, however, also brings enormous risks. Ransomware, Denial of Service, and Data Security – these should also be on everyone’s lips. Too often, they’re not.

I’m Izak Oosthuizen, a London IT thought leader, entrepreneur, and cybersecurity expert. I’m proud to be a member of the Entrepreneur’s Organisation London and was honored to be nominated for the prestigious UKTech50 award in 2022.

Over the years, I’ve accumulated several IT qualifications, including various Microsoft, Checkpoint, and VMware certifications. Combine that with my 20-plus years of experience in IT and management qualifications from the London School of Business & Finance and Cranfield School of Management, and you’ll find that I deeply understand that IT drives growth but also comes with associated security risks.

In 2006, I founded Zhero, a London-based end-to-end business cybersecurity and IT support company catering to SMEs. Zhero is a Microsoft Gold partner, and we specialize in providing tailored risk mitigation, cybersecurity, cloud solutions, IT support, consultancy, and professional services to a wide range of industry sectors, including medical, finance, legal, insurance, and architecture. We’ve had the privilege of working with brilliant minds and institutions such as WeWork, Giorgio Armani, Energy UK, Edmond De Rothschild, the Federation of Master Builders, City, University of London, and Dimension Data.

In addition to my work, I’ve co-authored two best-selling IT books, ‘Adapt and Overcome‘ and ‘Cybersecurity NOW,’ both available on Amazon. These books are essential reads for navigating the ever-changing worlds of cybersecurity, remote working, and the digitized workplace. My insights have also been featured in The Economist, UK Computer Weekly, and other prominent publications.

I’ve had the honor of being a keynote speaker at events hosted by The Economist, N-Able, and London Market Forums (LMF). At the recent LMF 2023 Cyber Resilience Leaders’ Summit, I had the privilege of sharing cutting-edge cybersecurity and risk mitigation strategies with contemporary pioneers such as Gary Brailsford-Hart, the Director of Information & CISO at City of London Police, and Simon Newman, the CEO of the Cyber Resilience Centre for London. It’s through these experiences that I continue to advocate for the importance of understanding and addressing the critical intersection of technology and security in our rapidly evolving digital landscape.


Izak and his team simply deliver - they're proactive, reliable, and always ready. Way ahead of the norm.​
Working with Izak on a personal level has always been very straight forward – his understanding of IT is both deep and broad.

My company has been a client of Izak for the last six years with regards to IT support and cybersecurity. We have found Izak to be very knowledgeable and has provided excellent IT services during this period. Izak is also proactive in informing us of upcoming technology and cyber threats.

Here's how I want to help you

Do you feel your business needs an ‘IT sanity check’?

I provide once-off consultancy and monthly business technology check-ins to assess the appropriateness of the technology and advice provided by your existing IT department or provider. 

This includes:

− Monthly workshops, planning and technology road-mapping
− SWOT analysis, priority setting and guidance
− Ongoing risk and cost assessments
− Immediate assistance in event of an emergency

Breaking through the valley of death is a difficult phase for any company. Did you know, only 4% of all companies reach £1 million in turnover?

No matter how complicated your business becomes, everything is ultimately about the freedom to grow, develop and explore. As a business owner myself, I had to navigate stabilising the organisation as we scaled. I can help and guide you with:

− Implementation and assistance with the Rockefeller Habits
− Developing and executing practical tools and strategies that work
− Accountable and realistic goal-setting

I provide transformative training on a one-to-one or a group basis. My training is for all levels of employees and anybody looking to gain practical expertise about their business technology. Offers include:

− Best practice, guidance and maintenance
− Training and security awareness
− New technology implementation

Are you part of a team or group that needs a little motivational boost? 

I offer strategic help to founders, entrepreneurs, CEO’s, IT managers, and anyone needing to develop their practical skills for their business and processes.

− Keynote speaker on various topics
− Brainstorming. solution-design, and problem-solving
− Motivational and incentivising talks
