Who we serve in Rapid City
Rapid City is South Dakota’s second-largest city, home to Ellsworth Air Force Base — selected as the operational base for the B-21 Raider — and Monument Health, one of the largest geographic health-system service areas in the country. That mix produces a regulated IT, AI, and physical-security profile: CMMC 2.0 / NIST 800-171-governed Ellsworth AFB defense supply chain, HIPAA-regulated regional healthcare, and NERC CIP-scoped utility operations. Armorstack runs one operating record across Verity, Core, Sentry, and Citadel — not four vendor relationships.
Defense / DIB
Defense suppliers around Ellsworth Air Force Base need CMMC 2.0 Level 1 / Level 2 implementation and assessor coordination, not a binder. Verity owns the SSP/POA&M path; Sentry and Core keep the boundary operable.
Healthcare
Hospitals, clinics, and care networks serving Rapid City carry HIPAA technical-safeguard and physical-security requirements — plus AI-assisted clinical tools that need governance, not a policy PDF. Core and Citadel converge IT and facility security; Verity holds the audit record.
Critical infrastructure
Utility and mining operators headquartered in Pennington and Meade counties need OT/ICS monitoring on the same record as physical access.

How we cover Rapid City
24/7 SOC monitoring
Sentry’s Security Operations Center monitors Rapid City client environments around the clock with shift coverage that spans Central Time business hours, evening overlap, and overnight handoff. For Defense Industrial Base clients, we maintain DoD-compliant escalation paths to the Defense Counterintelligence and Security Agency (DCSA) and the DoD Cyber Crime Center (DC3) when an incident reaches federal thresholds.
On-site engineer dispatch
Engineers are dispatched across Pennington and Meade counties for planned work and emergency response. Target on-site response is 4 hours during business hours and 8 hours overnight for clients on a service retainer. Routine on-site work is scheduled within one to two business days. Armorstack is a service-area provider in Rapid City — we do not claim a storefront we do not operate. When an incident reaches federal thresholds, our SOC coordinates with the FBI Minneapolis Field Office, which covers South Dakota.
vCIO and vCISO cadence
Quarterly executive reviews can be delivered on-site in Rapid City. Monthly cadence is available remote. Board-ready reporting is mapped to the frameworks that actually apply — typically CMMC 2.0, NIST 800-171, NIST CSF 2.0, NIST AI RMF, HIPAA, and NERC CIP for utility-adjacent scope.
AI security and the Rapid City observability gap
Rapid City’s defense, healthcare, and utility sectors are adopting AI faster than most security programs can govern it. That is the observability gap — enterprise AI adoption outpacing the visibility, governance, and monitoring required to make it safe. Sentry addresses it with shadow-AI detection, prompt-injection monitoring, excessive-agency detection, and agent kill-switch enforcement, paired with Verity’s AI risk reporting under NIST AI RMF. For Defense Industrial Base clients, undocumented AI usage in CUI environments is a CMMC finding waiting to happen. → Observability gap · AI security
