28 Domains of Homeland Security

BHS approaches homeland security as an interconnected ecosystem spanning national security, critical infrastructure, cyber and digital threats, resilience, law enforcement and emerging risks.

Eight categories

Where each domain sits

Every domain has its own page covering the security challenges it presents, what BHS provides, and the technology, consulting, integration and R&D that apply.

8. Strategic Collaboration

5 domains

Intellectual property, threat intelligence, R&D, trade routes and international collaboration.

Corporate Espionage & IP ProtectionProtecting trade secrets, intellectual property and sensitive information.Advanced Threat IntelligenceStrategic, tactical and cyber threat intelligence for early warning.Homeland Security R&DResearch, prototyping and technology development for security missions.Trade Route & Economic Infrastructure SecuritySecuring supply chains, ports, logistics and economic infrastructure.International CollaborationBHS's international operating philosophy: collaboration, partnership and capacity building.

Domains rarely act alone. Securing a mass gathering, for example, draws on crowd management, surveillance, emergency management, CBRN preparedness, communications and transport security at the same time — which is why BHS works across the whole ecosystem rather than one requirement at a time. See how that becomes a solution.
