About Obisec
Lean by design. Hands-on by habit.
Founded in 2001 by Dimitrios Zacharopoulos, who began in IT in 1986.
Why Obisec exists
The security industry often promised more than it delivered: reactive security, misaligned teams, and consultants who had never done the hands-on work. Obisec was set up to work differently, and since 2007 it has been fully independent.
How we work
No layers of middle management. You work directly with the person doing the job, every engagement is tailored, and every report is written to be acted on. For larger projects we bring in trusted peers who share our standards.
Beyond the technical
We assess teams, processes and people as well as systems, helping place people in the roles that suit them and spot overlooked talent.
Who we have worked with
Finance, healthcare, government, defence, education, telecoms, retail and critical infrastructure, across four continents.
Where
Based in South Wales and available globally: Wales, England, Scotland, Ireland, the EU, Africa and the United States. Expert witness work in the UK and The Hague.
