Insights

Government Contracting Expertise By Light has a strong track record of securing multi-million dollar government contracts across military, defense, and civilian agencies, including recent agreements with the Department of Veterans Affairs and the U.S. Army. This indicates robust relationships within federal agencies and opportunities for expanding services in government IT modernization, healthcare portals, and military simulation solutions.

Strategic Expansion & Acquisitions The company's recent acquisition of Veraxx Engineering and sustained growth in securing large-scale projects demonstrate a strategic approach to expanding capabilities and customer reach. This positions By Light as a key player capable of offering comprehensive cybersecurity, cloud services, and network modernization solutions to new defense and federal clients.

Investments in Cyber & Cloud By Light’s development of turnkey cloud services, secure video systems, and data center expansion shows a focus on advanced cybersecurity, data management, and cloud migration. These core areas offer significant upsell opportunities to federal agencies looking to modernize their IT infrastructure and enhance security measures.

Recognition & Industry Presence Recognition as a finalist for the Washington Area GovCon Award and active participation in industry events like IT2EC signal credibility and visibility in the government contracting sector.
