The Investigative Mission
Since its inception in 1865, the Secret Service was created to investigate and prevent counterfeiting. Today the agency’s investigative mission has evolved from enforcing counterfeiting laws to safeguarding the payment and financial systems of the United States from a wide range of financial and computer-based crimes. To combat these crimes, the Secret Service has adopted a proactive approach, using advanced technologies and capitalizing on the power of task force partnerships.
The U.S. Secret Service has a pivotal role in securing the nation’s critical infrastructures, specifically in the areas of cyber, banking and finance. Other directives address the need to combat transnational organized crime that targets the citizens and financial institutions of the United States. In response to the globalization of technology- based threats, the U.S. Secret Service’s investigative mission abroad is growing as well, creating the need for a heightened overseas liaison presence.
Today, multi-disciplined forensics experts, investigative experts and intelligence analysts provide rapid response and critical information in support of financial analysis, infrastructure protection and criminal investigations.
