Paramount Defense Group was co-founded by Dr. Zwi Ronai, Dominic King, Nick Peric, and Ranko Klacar, bringing together more than 80 years of combined experience across law enforcement, military operations, private security, investigations, executive protection, international operations, and senior corporate leadership.
At the centre of Paramount's strategic and operational development is Dr. Zwi Ronai, Co-Founder and Vice President of Global Operations. A former CEO of Titan Atalef, Dr. Ronai plays a critical role in shaping the company's direction, operational structure, international relationships, and long-term growth. His experience in leading complex organizations and coordinating high-level operations provides Paramount with the strategic discipline required to manage demanding security environments at both the local and international level.
Our leadership combines strategic thinking with practical field experience. Dr. Ronai provides the operational architecture and international perspective behind the organization, while the broader leadership team contributes extensive experience in executive protection, security management, investigations, asset protection, logistics, and field operations.
Our clients need more than personnel at a site. They need experienced leaders who understand risk, accountability, business continuity, and the consequences of operational failure. Paramount was built to provide that level of leadership. Our senior team remains directly involved in planning, deployment, oversight, and communication, ensuring that every engagement has clear responsibility and executive-level attention.
We do not approach security as a disconnected external service. We integrate security into the client's broader operating system, coordinating with management, legal counsel, human resources, logistics teams, and other stakeholders when required. This allows us to identify vulnerabilities, establish clear procedures, maintain reliable reporting, and respond quickly as conditions change.
Based in Toronto and operating across Ontario and internationally, Paramount Defense Group supports corporations, critical infrastructure operators, private clients, legal teams, property owners, and organizations facing complex security challenges. Each program is developed around the client's people, assets, facilities, operating environment, exposure, legal obligations, and business priorities.
Whether the assignment is local or international, temporary or ongoing, Paramount Defense Group delivers disciplined planning, tailored deployment, clear accountability, and direct access to senior leadership. Our clients know who is responsible, how the operation will be managed, and what standards will be maintained from the beginning of the engagement through completion.
