Trusted Federal Cybersecurity Experts and Specialists

The silver lining subcontractor to Federal Cybersecurity and Critical Infrastructure Protection Programs

What We Do

We are focused on being the "silver lining" subcontractor to prime contractors supporting both Federal civilian and Department of Defense cybersecurity and critical infrastructure protection programs.


We provide defense cybersecurity and cyber risk management services, including risk and vulnerability management and assessments, FISMA A&A support (e.g., ISSO and SCA), and cybersecurity analyst services. We also have specialists with experience in areas such as risk analysis, supply chain risk management (SCRM), cyber operations planning, and threat intelligence and hunting.

IT and Engineering

We offer a range of cybersecurity-related IT and network, systems, and solutions engineering services. Our experience includes the design, development, test & evaluation (T&E), and operation and maintenance (O&M) of enterprise- and carrier-grade systems.

Strategy, Planning, and Policy

We support the design and development of new cybersecurity-, emerging technology-, and critical infrastructure protection-focused programs through strategy, planning, and policy support activities.

Program/Project Management

We provide program and project management expertise, including project scoping and planning; schedule, cost, and risk monitoring and control; and subcontractor management. Our managers have led teams of various sizes from small task-driven teams to large, integrated programs with multiple partners and subcontractors. We also have expertise in managing portfolios of programs and balancing resources across them.

Research & Development

We support cybersecurity and other emerging technology R&D programs through the delivery of user needs and requirements gathering; technology foraging; horizon scanning; consortium management; piloting and prototyping; and test and evaluation support services.
