Our story: From frustration to solution
In the early 2000s, while working as a senior IT engineer in London, Izak saw the same problems repeated across organisations. Poor communication, slow support and technology confusions.
He knew there was a better way. So, in 2006, he left employment and launched his own IT support company, Exec-Sys, serving businesses throughout Greater London.
What began as a one-person operation evolved into a highly respected MSP with deep expertise across cybersecurity, cloud solutions, compliance, and strategic IT consultancy.
In 2015, the business rebranded as Zhero to better reflect its broader mission: helping organisations eliminate IT chaos and achieve more through responsive, measurable IT support.

Thanks Michael - super fast and helpful
I am an office manager in London with limited IT knowledge. I contacted Zhero to assist us in moving the IT architecture of our office smoothly. I am blown away. It is a big job and a lot of trust involved when seeking the right IT support and they were amazing. I didn't have to worry about a thing. They helped me understand all the ins and outs. They provided me with checklists and the move went so smoothly. There was little to no downtime. No lost emails. I would recommend them to anyone out there that needs a great IT support team.
Thank you Renier for the prompt response.
