Where We Deliver

Six core service areas

The complete capability framework — engineered for warfighter alignment, secure mission delivery, and operational resilience. Each area is built to stand alone or combine into a full-lifecycle engagement, from initial assessment through sustained operations. Together they give agencies a single accountable partner across cyber, modernization, and mission support.
Cybersecurity & Engineering

IT/OT architecture design, RMF assessments, SA&A support, vulnerability management, and endpoint protection aligned to NIST and DoD 8500-series requirements.

White papers: Vulnerability Management · Government RMF

Maritime IT/OT Assurance

Technology services for vessel convergence, port infrastructure protection, and IMO/USCG security compliance — supporting fleet readiness and mission continuity.

Why agencies and primes choose SEMAIS

Maritime depth that's hard to find

Most government cyber firms can do IT. Few can do shipboard and shoreside OT. We specialize in vessel convergence, port infrastructure protection, and IMO/USCG compliance.

Founder-Led Engagement

Leadership

Every SEMAIS engagement runs through the same senior practitioner — founder Dewayne Hart — bringing government cyber delivery, published thought leadership, and a global speaking platform to each contract. Agencies and primes work directly with the expertise they evaluated, not a layer of junior staff handed the work after award. That continuity means faster decisions, deeper accountability, and delivery that reflects decades of hands-on government experience.
