The Dalton Gang

What The Dalton Gang does

The Dalton Gang, Inc. (TDG) is a Service-Disabled Veteran-Owned Small Business (SDVOSB) headquartered in Warrenton, Virginia, founded in 2002 by retired USMC Colonel Tom Dalton. The company provides three core service lines to U.S. federal agencies: Assurance Services (security assessments, system Accreditation & Authorization, Risk Management Framework implementation, continuous monitoring, and CDM support under FISMA/NIST); Media Services (NIST SP 800-88 Rev. 1 compliant sanitization and physical destruction of sensitive electronic media, supported by a proprietary VA-facing Media Services Portal that issues Certificates of Destruction); and Software Development (Agile/DevSecOps delivery using Scrum, deployed in hybrid FFP and T&M models). Underlying proprietary assets include the copyrighted Senior System Managers (SSM) Course developed with Indiana University of Pennsylvania and the copyrighted Security Life Cycle methodology, both designed for federal information assurance practitioners.

Revenue is generated almost exclusively through federal government contracting, primarily as a prime contractor on GSA Schedule 70 (HACS SIN) and on agency-specific BPA and IDIQ vehicles, supplemented by subcontractor roles on larger programs and joint ventures (DV United, DV United2, Tandrydoon). Pricing is contract-vehicle based, with T&M labor at GSA rate schedules, FFP for software development milestones, and managed-services billing per device processed for media sanitization. The customer base spans 20+ federal agencies including USDA (MRP, APHIS, FNS), VA, FAA, USCIS, IRS, US Bureau of Reclamation, Army Cyber Command, and GSA OIG, with named contracts ranging in value from ~$102K (GSA OIG FISMA readiness) to a $45M IDIQ ceiling (DOI Bureau of Reclamation). Geographic footprint is limited to CONUS federal customers; the company operates from Warrenton, VA (headquarters) and Chantilly, VA (media destruction facility). Headcount sits in the 11-50 range with over 40% veterans, scaling delivery via joint venture teammate staffing.

Direct peers

• Sev1Tech: Sev1Tech is a Service-Disabled Veteran-Owned Small Business providing federal IT and cybersecurity services across federal civilian and defense agencies. Like TDG, it competes on RMF/A&A, FISMA compliance, and cleared talent, making it a near-direct comparable in size, set-aside positioning, and customer mix.
• IntelliBridge: IntelliBridge provides federal IT, intelligence, and cybersecurity services with deep experience supporting agencies such as the Department of Justice, DHS, and DoD. Like TDG, it competes in federal cybersecurity and mission IT services, with comparable scale and similar federal civilian/defense customer footprint.
• Applied Information Sciences (AIS): AIS is a Microsoft-focused federal IT services and cloud engineering firm delivering Agile/DevSecOps solutions to civilian agencies. Like TDG, it competes for federal software development and modernization contracts with a similar small-business profile and overlap on Agile delivery to civilian agencies.
• CALNET Technology: CALNET Technology is an SDVOSB federal IT services contractor providing cybersecurity, software development, and IT operations to federal civilian and defense agencies. Like TDG, it competes on the same federal set-aside contract vehicles and benefits from the same SDVOSB regulatory positioning.
• MetroStar Systems: MetroStar Systems is an IT services firm serving federal civilian agencies with digital transformation, cybersecurity, and Agile/DevSecOps delivery. Like TDG, it operates as a small-to-mid federal IT services contractor with similar customer base and SDVOSB-adjacent federal positioning.

Broad incumbents

• Leidos: Leidos is a top-tier federal systems integrator with significant cybersecurity and IT modernization practices serving IRS, FAA, and DHS. As a prime on programs where TDG serves as a subcontractor, Leidos sets the incumbent capture dynamic that constrains TDG's role on large federal engagements.
• ManTech International: ManTech (now under Carlyle) is a large federal cybersecurity and intelligence IT services firm with deep capabilities in RMF, A&A, and mission cyber for defense and federal civilian customers. It represents the scaled incumbent tier against which TDG must position itself on set-aside opportunities.
• Booz Allen Hamilton: Booz Allen Hamilton is one of the largest federal IT and cybersecurity consultancies, with a deep FISMA/RMF practice serving every major federal agency. As a broad incumbent, it competes with TDG on the same A&A, continuous monitoring, and cyber advisory engagements, but at vastly greater scale and with broader commercial capability.
• ECS Federal: ECS Federal is an ASGN company providing federal cybersecurity, cloud, and IT modernization services to defense and civilian agencies. As a mid-to-large federal cyber incumbent, it competes with TDG on the same continuous monitoring, A&A, and DevSecOps contract opportunities at federal civilian and DoD customers.

Others

• Iron Mountain: Iron Mountain's Secure IT Asset Disposition (ITAD) division provides NIST SP 800-88 compliant media sanitization and destruction services—the exact domain of TDG's Media Services business. While much larger and more commercial, Iron Mountain is a competitor for media sanitization contracts at federal agencies including the VA.
