Securing our Nation’s Most Critical Data

Secure Enterprise Network Systems, Services & Support (SENS3)


The vision of homeland security is to ensure a homeland that is safe, secure and resilient against terrorism and other risks. The Department of Homeland Security (DHS) defines its core missions as:

  • Preventing Terrorism and Enhancing Security
  • Securing and Managing Our Borders
  • Enforcing and Administering Our Immigration Laws
  • Safeguarding and Securing Cyberspace
  • Ensuring Resilience to Disasters


The DHS mission is dependent on a secure, reliable and capable classified information-sharing infrastructure that is interoperable across DHS and partner environments. 

Supporting the DHS Information Technology Services Office (ITSO) and Office of Intelligence & Analysis (I&A) with Secure Enterprise Network Systems, Services and Support (SENS3), General Dynamics IT helps to address the mission critical need to effectively maintain and securely manage classified information within the DHS enterprise, to include its federal, state, local and tribal partners, and associated stakeholders. 


SENS3 addresses the operations and maintenance, security, optimization, enhancement, design, engineering, architecture, integration, configuration, testing and deployment of DHS’ classified networks, infrastructure (including hardware and software) and other systems supporting the intelligence mission – collectively referred to as the SENS3 networks.
