Thornton Tomasetti applies engineering and scientific principles to solve the world’s challenges. An independent organization of creative thinkers and innovative doers collaborating from offices worldwide, our mission is to bring our clients' ideas to life and, in the process, lay the groundwork for a better, more resilient future. We provide support and opportunities to our employees to achieve their full potential and cultivate a rewarding career.

Our Protective Design & Security team prioritizes the protection of life and assets by mitigating consequences of security risks in the built environment. With more than 75 years of experience, our risk-led and strategic solutions safeguard people, property, and operations from intentional harm, evolving and emerging threats.

Whether safeguarding a cultural landmark, securing a healthcare facility, or planning for crowd safety at a major event, our approach is grounded in intelligence, simulation, and human-centered design to deliver resilient solutions with demonstrable performance and lasting impact.

Within our practice, you’ll be introduced to how risk-based design brings together security planning, physical security, and electronic security to develop layered protection strategies.
