DHS Software Contractor
Secure software development for CISA, CBP, ICE, TSA, FEMA, and USCIS programs. HSAR-compliant. Section 508 accessible. DHS 4300A-aligned security architecture. Based in South Carolina.
What does a DHS software contractor deliver?
A DHS software contractor builds secure web applications, mission-critical data platforms, and legacy system modernizations for Department of Homeland Security agencies under HSAR-compliant contracts. Code and Trust serves CISA, CBP, ICE, TSA, FEMA, and USCIS with DHS 4300A-aligned security architecture, Section 508 accessible interfaces, and NIST 800-53 ATO documentation as standard delivery artifacts.
DHS encompasses 22 agencies with distinct missions, acquisition vehicles, and compliance requirements. CBP and ICE programs involve law enforcement sensitive data requiring controls beyond standard CUI protocols. CISA programs intersect with critical infrastructure security. FEMA and USCIS programs prioritize public-facing accessibility. Code and Trust has experience across the full DHS component spectrum — not just the civilian-agency generics that most contractors apply.
DHS components we serve
Code and Trust serves six primary DHS components: CISA (critical infrastructure and cyber defense platforms), CBP (border management and trade data systems), ICE (case management and enforcement workflows), TSA (screening and operations software), FEMA (disaster response and grants management), and USCIS (case processing and public-facing digital services).
Cybersecurity & Infrastructure Security Agency
CDM platforms, threat intel systems, secure shared services, and critical infrastructure protection software under CISA prime contractor vehicles.
Customs and Border Protection
Border management software, trade data systems, and law enforcement-sensitive data platforms with HSAR-compliant security controls and audit logging.
Immigration and Customs Enforcement
Case management, data integration, and enforcement workflow systems handling LES data under ICE contract vehicles and data handling requirements.
Transportation Security Administration
Passenger screening systems, workforce management, and operations software under TSA acquisition vehicles with DHS 4300A compliance.
Federal Emergency Management Agency
Disaster response platforms, grants management systems, and public-facing emergency information portals with 508-accessible interfaces.
U.S. Citizenship and Immigration Services
Case processing systems, applicant-facing digital services, and legacy modernization for USCIS enterprise IT under the USCIS IDIQ ecosystem.
DHS-specific compliance requirements
DHS software compliance layers three frameworks on top of standard FISMA: DHS 4300A (Information Technology Security Program Policy) adds DHS-specific control implementation requirements; HSAR (Homeland Security Acquisition Regulation) adds DHS clauses to FAR contracts; and component-specific overlays for law enforcement sensitive data (CBP/ICE) and critical infrastructure (CISA) extend the baseline further.
DHS 4300A Compliance
DHS Sensitive Systems Policy Directive 4300A governs information security for all DHS information systems. It adds DHS-specific requirements on top of FISMA and NIST 800-53 — including DHS-specific control implementation guidance, reporting requirements, and the DHS ATO process timeline. Code and Trust builds systems that satisfy both the NIST baseline and the 4300A overlay.
HSAR Contract Vehicles
The Homeland Security Acquisition Regulation (HSAR) adds DHS-specific clauses to FAR-based contracts. Key HSAR clauses affect data rights, security incident reporting, and contractor access to DHS facilities and systems. Code and Trust operates under HSAR-compliant contracts and understands the clause differences from standard FAR Part 52 provisions.
Law Enforcement Sensitive (LES) Data Handling
CBP and ICE programs routinely involve LES data — law enforcement information with restrictions on access, distribution, and storage that exceed standard CUI protocols. Code and Trust implements role-based access control, comprehensive audit logging, and data compartmentalization specifically designed for LES-categorized systems.
Section 508 for Public-Facing DHS Services
FEMA disaster assistance portals, USCIS case status systems, and TSA PreCheck enrollment interfaces must meet Section 508 Refresh (WCAG 2.1 AA) requirements — serving a public that includes users with disabilities who depend on government digital services. Code and Trust builds and remediates 508-compliant public-facing DHS software with VPAT generation at delivery.
DHS software contractor — common questions
DHS software contractor questions most often cover which components Code and Trust serves, DHS-specific compliance beyond standard FISMA, contract vehicles for DHS work, law enforcement sensitive data handling, CISA program specifics, and Section 508 requirements for DHS public-facing systems. All six answered with specifics below.
What DHS components does Code and Trust serve?
Code and Trust serves CISA (Cybersecurity and Infrastructure Security Agency), CBP (Customs and Border Protection), ICE (Immigration and Customs Enforcement), TSA (Transportation Security Administration), FEMA (Federal Emergency Management Agency), USCIS (U.S. Citizenship and Immigration Services), and the DHS Office of the CIO. We work under HSAR-compliant contracts as a prime or subcontractor.
Does DHS software require special compliance beyond standard FISMA?
DHS programs may require compliance with DHS 4300A (Information Technology Security Program) in addition to FISMA and NIST 800-53. CBP and ICE programs handling law enforcement sensitive (LES) data have additional data handling requirements. CISA programs may involve coordination with ICS/SCADA security requirements. Code and Trust has experience with DHS-specific compliance overlays on top of the standard NIST RMF process.
What contract vehicles does Code and Trust use for DHS work?
DHS software work flows through EAGLE II (Enterprise Acquisition Gateway for Leading-Edge Solutions), SEWP V, CIO-SP3, and OASIS SB IDIQs, as well as direct agency contracts under simplified acquisition and OTAs for prototype work. DHS also uses the Homeland Security Acquisition Regulation (HSAR) which adds DHS-specific clauses to FAR-based contracts. Code and Trust supports all standard DHS procurement vehicles.
Does Code and Trust handle law enforcement sensitive (LES) data in DHS systems?
Yes. CBP and ICE programs routinely involve law enforcement sensitive data requiring additional access controls, audit logging, and data handling procedures beyond standard CUI protocols. Code and Trust implements LES-appropriate access control, role-based data compartmentalization, and comprehensive audit trails as part of the standard security architecture for law enforcement agency engagements.
What is CISA and does Code and Trust work on CISA programs?
CISA (Cybersecurity and Infrastructure Security Agency) is the nation's cyber defense agency, responsible for protecting critical infrastructure and federal civilian networks. CISA programs include continuous diagnostics and mitigation (CDM), shared services platforms, and threat intelligence systems. Code and Trust supports CISA prime contractors with secure software development aligned to CISA's own cybersecurity guidelines.
How does Code and Trust handle Section 508 for DHS-facing software?
All DHS software Code and Trust delivers meets Section 508 Refresh (WCAG 2.1 AA) requirements. DHS has an active 508 compliance office and requires completed Accessibility Conformance Reports (ACRs / VPATs) before software can be approved for operational use. We produce VPATs as a standard delivery artifact and conduct automated axe-core scanning plus manual screen-reader testing on all DHS-facing interfaces.
Related federal software services
DHS software contracting connects to four adjacent capabilities: ATO-compliant software for NIST 800-53 and DHS 4300A authorization, Section 508 accessible software for public-facing DHS portals, cleared developer staffing for DHS programs requiring personnel security clearances, and DoD software contracting for programs spanning both homeland security and defense missions.
