Cybersecurity compliance guidance for organizations supporting the Department of Defense
#1 Cyber works with organizations across the Defense Industrial Base that are required to protect Controlled Unclassified Information (CUI) and comply with DFARS, NIST SP 800-171, and CMMC requirements.
While each organization’s environment is different, many face similar challenges: understanding expectations, scoping systems correctly, implementing controls responsibly, and preparing defensible documentation. Our role is to help organizations across industries address these challenges with clarity and structure.
Defense Contractors
We support prime and subcontractors performing work directly for the Department of Defense. Our guidance helps contractors interpret cybersecurity requirements tied to contracts, prepare documentation, and align implementation with assessment expectations.
Manufacturing & Industrial Organizations
Manufacturers and industrial suppliers often handle CUI as part of defense-related production, design, or logistics activities. These environments can present unique challenges due to legacy systems, operational constraints, and mixed IT/OT considerations.
Engineering & Technical Services Firms
Engineering, aerospace, and technical services firms frequently support DoD programs that involve sensitive data, intellectual property, and technical information.
Technology & Software Providers
Technology companies supporting defense customers often face complex environments involving cloud services, remote workforces, and integrated systems.
Subcontractors & Small Businesses
Many small businesses and subcontractors are required to meet cybersecurity requirements to continue supporting prime contractors. These organizations often need clear, practical guidance without unnecessary complexity.
