Turning Identity Chaos into Compliance and Control Across 52+ Federal Agencies
Federal Civilian Agency · CDM Program · NIST / OMB Compliance
A lead federal agency responsible for government-wide cybersecurity needed to deploy industry-standard privileged access governance across its own systems and extend that capability to over 50 civilian agencies. Independently operated sites had separate IAM processes, inconsistent privilege controls, and no unified compliance posture — creating significant NIST and OMB audit exposure.
Trustmarq designed and deployed a centralized IAM governance solution aligned to NIST 800-53 and CDM program requirements. The solution standardized privileged identity management, automated compliance workflows, and created a scalable model that could be extended to downstream agencies — including implementation of role-based access controls, continuous monitoring, and audit-ready reporting dashboards.
Governance capability extended to 52+ federal agencies. Eliminated fragmented IAM processes across independently operated sites. Achieved full alignment to OMB standards with audit-ready documentation. Reduced manual privilege management overhead by automating identity lifecycle events and access certifications.

Restoring Identity Integrity at Enterprise Scale: 130K Orphan Accounts Resolved in 60 Days
Major Credit Bureau · SailPoint IIQ · IGA / Identity Governance
A major credit reporting organization had accumulated approximately 130,000 orphan identities across hundreds of enterprise applications — the result of inconsistent termination processes, M&A activity, and years of manual identity management. Each orphan account represented a compliance gap, a potential breach vector, and an audit finding waiting to happen under GLBA and PCI-DSS requirements.
Trustmarq leveraged the client's existing SailPoint IdentityIQ investment — avoiding new platform costs — to design and implement automated orphan detection, remediation workflows, and ongoing joiner-mover-leaver governance. The solution included custom connectors for the organization's heterogeneous application landscape and automated certification campaigns to surface and close access gaps at scale.
Orphan account population reduced from 130,000 to under 10,000 within 60 days — a 92% reduction. Ongoing IGA automation prevented recurrence. Audit posture dramatically improved with real-time access visibility and automated evidence generation for GLBA and PCI-DSS compliance cycles.

Interim CISO Stabilizes Healthcare Security Program During Leadership Transition
Regional Health System · HIPAA / HITECH · Risk Management Program
A regional health system faced an unexpected CISO departure six weeks before a scheduled HIPAA compliance audit. With no internal successor ready and a board demanding continuity, the organization needed immediate executive-level security leadership — without the 4–6 month timeline of a full-time hire. The existing security program lacked documented risk management processes and had open audit findings from the prior year.
Trustmarq placed an interim CISO with deep healthcare and HIPAA expertise within one week of engagement. The interim CISO stabilized board communication, led a rapid risk assessment, closed priority audit findings, and built a 90-day remediation roadmap. Simultaneously, Trustmarq supported the search for a permanent CISO by defining the role requirements, building out the security team structure, and onboarding the incoming executive upon hire.
Compliance audit completed successfully with no material findings. Board confidence maintained through continuous reporting during the transition. Permanent CISO onboarded into a stable, documented program — reducing the typical new-leader ramp time from months to weeks. Ongoing HIPAA risk management program established for long-term compliance sustainability.

GRC Automation and Supply Chain Risk Management for NERC-Regulated Utility
Major Electric Utility · RSA Archer · NERC CIP / Supply Chain Risk
A large regulated electric utility needed to modernize its risk management program to satisfy increasing NERC CIP requirements and manage growing third-party supply chain risk. Manual processes for tracking vendor risk, managing compliance evidence, and reporting to regulators created significant operational burden and audit exposure — particularly following NERC's supply chain standards expansion.
Trustmarq implemented an integrated GRC and TPRM solution on the RSA Archer platform — automating the business criticality matrix for vendor classification, streamlining supply chain risk assessments, and building executive reporting dashboards mapped to NERC CIP control requirements. The implementation included automated risk scoring, workflow-driven remediation tracking, and integration with the utility's existing operational systems.
Manual compliance processes replaced with automated workflows, reducing program management overhead by an estimated 60%. Supply chain vendor risk assessments standardized and accelerated. NERC CIP compliance reporting automated with real-time dashboards for executive and regulator audiences. Risk posture visibility improved across the full third-party ecosystem.

Privileged Access Automation and Identity Governance for Federal Financial Regulator
Federal Financial Regulatory Agency · CyberArk · SailPoint · SCIM
A federal financial regulatory agency required modernization of its privileged user management program to align with updated federal identity standards and reduce manual provisioning burden. Privileged user attribute management was largely manual, audit evidence was difficult to compile, and the existing toolset lacked integration between the privileged access management platform and the agency's identity governance solution.
Trustmarq implemented a SCIM-based integration between the agency's SailPoint IGA platform and CyberArk PAM environment — automating privileged user attribute management, synchronizing identity data in real time, and enabling automated access certification campaigns for privileged accounts. The solution included custom development for agency-specific workflows and full audit trail capabilities for federal reporting requirements.
Privileged user provisioning and deprovisioning automated end-to-end, eliminating manual intervention for routine lifecycle events. Identity governance and PAM platforms fully synchronized, providing a single source of truth for privileged access. Audit evidence generation automated, reducing compliance reporting preparation from weeks to hours.

IAMManufacturing / IndustrialZero Trust
Zero Trust Identity and Network Segmentation for Industrial OT Environment
Industrial Manufacturer · Microsoft Entra ID · OT / ICS Security
A multinational industrial manufacturer was running unprotected operational technology systems accessible via legacy VNC tools — with no identity-based access controls separating IT from OT networks. The environment included ICS/SCADA systems controlling manufacturing processes, creating both cybersecurity and human safety risk. Regulatory requirements and cyber insurance requirements demanded urgent remediation.
Trustmarq micro-segmented the IT and OT network environments and integrated the access control layer with Microsoft Entra ID — enabling identity-based authentication for OT system access without disrupting manufacturing operations. The solution included network segmentation design, identity federation between corporate and OT domains, multi-factor authentication for all privileged OT access, and ongoing monitoring integration with the client's SOC.
Legacy VNC exposure eliminated. Identity-based access controls enforced across IT and OT environments with full audit trail. Manufacturing operations continued without interruption during implementation. Cyber insurance requirements satisfied, unlocking policy renewal. Zero Trust architecture established as foundation for ongoing OT security program.
