Managed IT, security and connected observability in Rapid City

We combine MSP operations with the Managed Intelligence Provider (MIP) model across supported infrastructure, identity, applications, networks, security, resilience, physical systems and AI for regulated organizations in Rapid City and Pennington and Meade counties — one accountable team, and a record your auditor can use. The full planned toolset is included upfront in one package, without tool tiers or tool upsells. Activation depends on integration readiness and accepted coverage; service scope, exclusions and service levels are agreed for the engagement. Inclusion does not mean unlimited services or general availability.

SOC 2 Type II · CISA-credentialed leadership · Coverage defined in scope

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.

Four portfolios, operated in Rapid City

How we work

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. On-site response targets are confirmed in the applicable service agreement. 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.

Rapid City’s defense, healthcare, and utility sectors are adopting AI faster than most security programs can govern it. That observability gap spans infrastructure, identity, applications, cyber, physical systems, and AI wherever telemetry or accountable ownership is missing. Fabric — DISCOVER (planned; not generally available), Pulse — CORRELATE, Miralto — PROVE, and SENTRYAI — ENFORCE describe the product roles. Enablement depends on documented readiness and supported integrations. Sentry supports detection and investigation of shadow AI, prompt-injection patterns, and excessive-agency behavior where telemetry is available, with authorized containment only where integrated and validated, 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
