REI Systems is relentlessly committed to safeguarding the American people, our homeland, and ensuring we are helping improve the lives of citizens. Security agencies help America face threats from foreign assaults, natural disasters, physical and digital infrastructure attacks, and domestic terrorism. The threats can happen quickly, and the repercussions can be severe and affect millions of American lives. Security agencies need to respond swiftly, decisively, and effectively. Having the right technology to respond to a myriad of threats is critical. Our partnership with the Department of Homeland Security (DHS) to achieve this goal has been long and successful. We provided technical solutions that:
- Help facilitate the lawful immigration process
- Use artificial intelligence to save lives after a natural disaster
- Harness a data analytics tool that delivers insight into what mission areas need resources based on risk levels
- Manage a portfolio of businesses which offer new capabilities that protect the homeland
We offer our full suite of services to DHS including application modernization, grants management systems development, data analytics, and advisory services. Our success stories below offer details about the technology, innovation, services, and impact our partnership has achieved over the past 20 years to advance DHS’s mission.
Partner Success Stories
APPLICATION MODERNIZATION
Electronic Immigration System (ELIS) – USCIS

GRANTS MANAGEMENT SYSTEMS/APPLICATION MODERNIZATION
NEMIS, EMMI, AND EADIS — FEMA
REI is helping modernize the National Emergency Management Information System -Emergency Coordination (NEMIS-EC) application, which The Federal Emergency Management Agency (FEMA) uses to manage emergency and disaster relief operations. NEMIS-EC helps FEMA in tracking incidents such as the COVID-19 pandemic across states and territories and supports the launch of FEMA financial systems to begin granting funds. REI provides planning, development, and implementation services in support of emergency coordination and incident management mission requirements. REI also helped modernize the Emergency Management Mission Integrated Environment (EMMIE), which automated grant business processes that support public agencies (states, local, territorial, and tribal governments) across both non-disaster and disaster grant programs, consolidating more than 24 disaster-focused grants programs into one web-based application to reduce the burden on grant recipients, streamline processes, and strengthen compliance. Finally, for more than ten years, REI supported FEMA’s Enterprise Applications Development Integration and Sustainment (EADIS) program to gradually transform the Agency’s IT infrastructure from a siloed set of applications utilizing multiple platforms, standards, and hosting environments to one unified IT architecture.
Electronic Handbooks — DHS Science & Technology
REI modernized, maintained, and operated the Electronic Handbook system used by the DHS’ Science and Technology Directorate to identify, solicit, select and manage contracts and cooperative agreement recipients who offered innovative technologies that protected the American Homeland. Those awardees developed innovations for both DHS and commercial needs, related to chemical and biological weapon detection, cybersecurity, critical infrastructure resilience, and other DHS priorities. The tools and capabilities we developed attract offers of innovations from hundreds of firms.
DATA AND ANALYTICS
FEMA Data Exchange Program (DEX)

To build the system, REI used a hybrid of opensource, COTS, and cloud-native services and utilized an Everything as a Service (XaaS) model to provide maximum flexibility for data storage, security, cleansing, standardization, and analytics. FEMADex is an Azure Cloud Data Platform designed for multicloud compatibility. It has domain-based data lakes and employs best-of-breed hybrid analytics tools. Throughout the project, REI used its Agile Delivery Framework approach to ensure value and capabilities were delivered to users rapidly and continuously.
FEMA Enterprise Analytics Support (EAS)
FEMA’s Office of Program and Policy Analysis (OPPA), Enterprise Analytics Division (EAD) partnered with REI to improve data analytics across the enterprise to better deliver critical information, tools, and insight to stakeholders helping people before, during and after a disaster. REI will support EAD’s mission requirements to encourage and enable FEMA to make data-driven decisions by empowering EAD’s analytics strength, building cross-cutting analytic capabilities, and supporting the transformation of data into actionable insights through maturing data infrastructure. REI will specifically strengthen FEMA’s ability to make data-driven decisions through cross-cutting enterprise analyses and analytic resources; advance FEMA’s analytics community via training, mentoring, and resource and capabilities sharing; mature data management; improve accessibility, transparency, and standardization of data and tools; and enhance stakeholder access modernized IT systems and streamlined business processes for better data management, data analytics, and reporting.
Management Cube — DHS Undersecretary for Management

ADVISORY SERVICES
FEMA Technology Business Management (TBM) — DHS Headquarters/ Office of the CIO
REI conducted two pilots for a TBM Cost Model that would enhance cost transparency for IT spending at DHS headquarters. The purpose was to inform guidance for TBM implementation across the Department. Our team documented current state processes, developed templates and reports, and provided a capabilities assessment, along with findings and recommendations for improvements. We also developed a draft roadmap for TBM implementation and sample adoption plans to provide DHS with a foundation to begin their TBM implementation, enabling a multi-dimensional view of IT costs to ensure effective and efficient use of IT resources for maximum business value.
