About Us

While there are many security organizations that serve the Fortune 100, Antigen Security serves organizations of all shapes and sizes. This is because we know threats affect everyone, no matter how small or large the organization.

At Antigen Security, we understand the connection our business has to individuals, communities, and the local economy. That’s why we’re committed to helping our clients protect themselves from threats.

The founders of Antigen Security met while working together in the Information Security community in Michigan, and have taken that passion for community, education, and supporting individuals and groups to fulfill on projects, conferences, and educational material across Michigan and at information security conferences throughout the US.

Antigen Security’s mission is to stop crime, fight fraud, and tackle threats for organizations to protect our community, people, and way of life.
