Business coach on decision making in complex environments

Expert in data management and security

Gareth Tennant is a former head of operational intelligence for the Royal Marines, who over an extensive career specialised in Intelligence, Surveillance and Reconnaissance operations. Having learnt and honed his trade in some of the worlds toughest and most complex environments from combat in Afghanistan to tracking pirates in Somalia, he became a global leader in the art of ‘Information Exploitation’. He now supports business leaders, governments and security services in the art of decision making in complex environments. He ensures they can adapt as the threats change; he has worked extensively in the developing world of cybersecurity and the use of social media as an intelligence tool. He is used to integrating new paradigms into established institutions.

Gareth’s use of visceral examples, from the world of human conflict and espionage, captivates audiences.
