ZeroBitHey, I'm
Tibo Claesens.
Cybersecurity professional based in Belgium. I do pentesting, security audits and help organisations understand where they're vulnerable — and what to do about it.
About
I started my career as a web application developer at Imengine, then moved into cybersecurity at Deloitte where I worked as a Senior Cyber Security Professional. I later founded ZeroBit to make security advice more accessible to smaller organisations.
Today I focus on what I enjoy most: pentesting, security research, and writing about what I learn along the way.
Current projects
What I do
Pentesting
Finding vulnerabilities in web applications, networks and infrastructure before someone else does.
Security advising
Helping teams understand their risk posture and take practical steps to improve it.
Writing
Sharing what I learn through honest, jargon-free articles on this blog.

How does the sales process work at ZeroBit?
We are straightforward people. No unnecessary fuss, please. Want a pentest? We can do that. Want a quote? We can do that too.
