Why SEMAIS

A specialist, not a generalist

SEMAIS is a service-disabled veteran-owned small business focused on two things the government can’t afford to get wrong: securing mission systems and keeping them modern. Our depth in cybersecurity governance and maritime IT/OT assurance gives agencies a partner who understands both the compliance framework and the deck plate.

Led by CEO Dewayne Hart — a U.S. Navy veteran with 20 years as a Fire Controlman — SEMAIS brings firsthand knowledge of the shipboard and government environments it now defends.

Core Capabilities

Two areas we own — and the services that support them

Cybersecurity and maritime IT/OT assurance anchor our practice, where decades of government and naval experience run deepest. Around that core, warfighter alignment, modernization, advisory, and workforce development extend the same security discipline across the full mission. Agencies can engage one practice or combine them under a single accountable partner.

Cybersecurity & Compliance

RMF, FISMA, and FedRAMP support; ATO packages; continuous monitoring;
vulnerability management; and security program management (C-PMO) for government information systems.

Maritime IT/OT Assurance

Cyber assurance for shipboard IT and operational technology — combat systems
readiness, system integration, and fleet modernization grounded in real naval
operations.

Warfighter Alignment

Engineering and securing systems to the operational realities of the mission — so technology supports the warfighter rather than constraining them.

AI & Modernization

Engineering modernization roadmaps and transformation strategies for legacy government technology.

Advisory Services

Governance, risk, and compliance
alignment that connects security
programs to mission outcomes.

Workforce Development

Cybersecurity training and readiness programs that build lasting internal capability.

Our Approach

Assess. Detect. Protect.

SEMAIS follows a simple, repeatable arc on every engagement. We assess the security architecture to find where risk and compliance gaps concentrate, detect the threats and weaknesses already present, and protect the systems with controls matched to the mission. It is the same disciplined method whether we are securing a single system or an enterprise.

Assess Security Architecture

We pinpoint where compliance gaps and risk are doing the most damage across your platforms.

Detect Operational Gaps

We surface the operational requirements andunknowns that standard reviews miss.

Design Protection Strategies

We build a comprehensive, prioritized plan that keeps pace with evolving threats.
