Tactical Defense Concepts (TDC) - was created by Joseph Tenaglia, a renowned United States’ Naval Commander who recognized the importance and urgency of providing threat awareness and security services to the maritime sector.

Tenaglia’s personal experience training thousands of maritime personnel in the government and commercial sector is the foundation for TDC’s threat awareness and security training. This experience includes developing and instructing an anti-terrorist course for Department of Defense operated and contracted vessels.

Tactical Defense Concept’s services are in compliance with:

• The United Nations International Maritime Organization (IMO)
• The International Ship and Port and Facility Security (ISPS) Code Amendments to the International Convention for the Safety of Life at Sea, 1974 (SOLAS Convention)
• Maritime Transportation and Security Act of 2002 (MTSA)
