IT Security Director, OPAP SA







I am very proud of my team and the work we have accomplished up to now. Yes, there have been hard times and several challenges, but this is where we are tested.

We manage to stay focused on our vision and at the same time openminded to understand new trends and incorporate them in our strategy.

Security is an enabler of business and we all must learn to work together for the benefit of our company.

There are no silos, and we (the security team) must be the first ones to support that in practice.
