Shivaji Sengupta

Client: U.S. Marshals Service (USMS)

Duration: 4+ Years

Focus Areas: Certification & Accreditation, RMF, SIEM, Vulnerability Assessment, Application Security, Identity Management, Digital Forensics

Clearance Level: Cleared IT/Cybersecurity Support

The Challenge

The U.S. Marshals Service (USMS) initially engaged Magnus Management Group to support its cybersecurity program across 17 enterprise applications. The scope of the engagement included:

  • Certification and Accreditation (C&A)
  • Risk Management Framework (RMF) support
  • Security compliance and A&A documentation
  • Security Information and Event Management (SIEM)
  • Log analysis and monitoring
  • Vulnerability assessments and intrusion detection
  • Security engineering

Given the complex mission and high-security requirements, the program demanded precise execution, compliance with federal cybersecurity standards, and consistent collaboration with the USMS CISO and COR.

Magnus Solution

Upon joining the program, Magnus conducted a comprehensive assessment and identified additional security gaps not originally scoped. These included:

  • Application development security
  • Mobile device and mobile application security
  • Identity and Access Management (IAM)
  • Digital forensics capabilities

Magnus worked closely with the USMS CISO and COR to realign the project scope and expand the cybersecurity team’s capabilities—without compromising existing milestones or timelines.

Results & Impact

  • ✅ 100% Milestone Achievement: Magnus has successfully met all scheduled milestones over 4+ years, often exceeding SLA benchmarks.
  • ✅ No Cost Escalation: Magnus delivered original scoped services with zero cost escalation, maintaining fiscal discipline and contract integrity.
  • ✅ Optimized Resource Utilization: By cross-leveraging existing team members, Magnus enabled the government to add 4 new task areas with just a $4M net increase, compared to a projected $6M+ spend on a separate contract.
  • ✅ Quarterly Business Reviews (QBRs): Regular QBRs ensured transparent performance monitoring, compliance validation, and SLA alignment with USMS leadership.

Key Success Factors

  • Proactive Gap Identification: Magnus went beyond the initial task order to uncover and address critical security requirements, strengthening overall agency posture.
  • Collaborative Mission Partnership: Magnus’s close collaboration with the CISO and COR enabled dynamic project realignment without disruption to existing services.
  • Efficient Task Expansion: New security functions were integrated through smart staffing and resource realignment—delivering more value at a lower incremental cost.

Conclusion

This engagement underscores Magnus Management Group’s ability to not only meet complex cybersecurity requirements, but also elevate mission performance through proactive problem-solving and operational efficiency. The USMS continues to benefit from a scalable, responsive cybersecurity program delivered by a trusted partner invested in its success.
