"I have met Mladen professionally on several occasions.
As a lecturer, he could outstandingly transfer knowledge, using good examples and helping participants master complex matters such as the domain of security operations.
As a consultant, he very well and accurately noticed the parts of the system that needed to be improved.
As an auditor, he has demonstrated an excellent knowledge of the standards by which he conducts audits. Through additional questions and requests, he helped us understand the essence of the requirement and show that we fulfilled it. How he conducted the audit made us feel like partners in finding room for improvement, not as the auditee.
I'm hoping to get a chance to meet Mladen soon."
