Managed Detection & Response (MDR) and SOC-as-a-Service for Regulated Mid-Market
Armorstack SENTRY delivers 24/7 SOC monitoring, managed SIEM, proactive threat hunting, and incident response as a single converged program — purpose-built for healthcare, financial services, defense contractors, and manufacturers who need continuous detection without the cost and complexity of building it in-house.
Threats don’t keep business hours. Neither do we.
The Problem: Alert Fatigue, Coverage Gaps, and a Tool Stack Nobody Can Afford to Run
Most mid-market security teams face a contradiction: they operate in highly regulated industries that demand continuous monitoring, but they cannot staff, fund, or sustain the infrastructure that continuous monitoring actually requires. The result is an organization that looks compliant on paper and is invisible to threats in practice.
Alert Fatigue Is Eating Your Team
A modern environment — endpoints, cloud workloads, identity systems, OT networks, and physical access infrastructure — generates hundreds of thousands of log events per day. Security tools designed to help detect threats have instead created a second problem: security analysts spending the majority of their time triaging noise. SANS research consistently places average alert-to-investigation ratios in the hundreds-to-one range. Every alert that goes uninvestigated is a potential incident that goes undetected.
The 24/7 Coverage Gap Is a Liability, Not a Trend
Ransomware operators, supply chain attackers, and nation-state actors do not schedule intrusions during business hours. Industry data from Mandiant, CrowdStrike, and other threat intelligence sources repeatedly shows that intrusions most frequently escalate outside standard working hours — evenings, weekends, and holidays — precisely because that is when detection and response capacity is thinnest. A security team that operates from 8 AM to 5 PM, five days a week, has created a predictable window. Adversaries know it exists.
Building an In-House SOC Is a Strategic Trap for Mid-Market Organizations
A properly staffed, operated, and tooled Security Operations Center requires a minimum of six to eight full-time analysts to maintain genuine 24/7 coverage across three shifts, plus lead analysts, a threat intelligence function, SIEM engineering, playbook development, and leadership. Industry benchmarks place the fully-loaded annual cost of building a credible in-house SOC — including staffing, tooling, infrastructure, and training — well into seven figures before a single alert is triaged. For mid-market organizations, that is not a realistic allocation. It pulls resources away from core business operations, and it still does not solve the talent shortage: cybersecurity unemployment is effectively at zero, and experienced SOC analysts are among the hardest positions to fill and retain.
Tool Sprawl Is the Integration Tax Your P&L Is Already Paying
The standard mid-market security response to coverage gaps has been to add tools: an EDR platform here, a standalone SIEM there, a dark web monitoring subscription, a separate threat intelligence feed, a vulnerability scanner, and a point solution for every new threat category that generates a board conversation. The result is what Armorstack calls the Integration Tax — the compounding cost in licensing, integration labor, staff training, and alert management overhead that organizations pay when they try to assemble a security program from disconnected point products rather than operating a unified program. Six vendors, six consoles, six renewal cycles, six points of failure, and no one vendor who owns the outcome.
SENTRY Managed Detection & Response eliminates the Integration Tax. One program. One team. One SLA. One throat to choke.
What MDR and SOC-as-a-Service Actually Mean — and How They Differ From What You May Already Have
These terms are used imprecisely across the industry. Before evaluating any provider, it is worth understanding what the distinctions actually mean for your organization’s risk posture.
Managed Detection and Response (MDR)
MDR is an outsourced security service that combines technology — typically a SIEM, EDR, and/or XDR platform — with human analysts who actively monitor your environment, investigate alerts, and respond to confirmed threats. The key word is “response.” An MDR provider does not simply hand you a report of what happened. A mature MDR program includes active containment, host isolation, and remediation guidance delivered in real time. SENTRY MDR is built on this model: detection is automated and enriched with threat intelligence; response is human-led and documented to compliance standards.
SOC-as-a-Service
SOC-as-a-Service delivers the function of a full Security Operations Center — continuous monitoring, triage, investigation, escalation, and reporting — as a managed program rather than an internal department. Where MDR tends to be technology-led (the platform is the anchor), SOC-as-a-Service is program-led: you are buying the analyst team, the operational processes, the compliance documentation, and the continuous improvement cycle, with the technology underneath it. Armorstack SENTRY provides both under a single engagement — the technology is managed and the human program is included.
How MDR Differs From a Standard MSSP
A traditional managed security services provider (MSSP) typically monitors and alerts. The distinction matters operationally: an MSSP delivers alerts to your team, and your team is expected to investigate and respond. MDR providers — and Armorstack, as a Managed Intelligence Provider — investigate and respond. The operational burden shifts from your internal team to SENTRY. This distinction is critical for regulated industries where the gap between detection and containment directly determines regulatory exposure and breach notification obligations.
MDR vs. DIY SIEM
Running your own SIEM — whether Splunk, Microsoft Sentinel, IBM QRadar, or another platform — is not a substitute for MDR. A SIEM is a tool; MDR is a program that includes a SIEM as one component. DIY SIEM deployments in mid-market organizations frequently suffer from undertuning (too many alerts, too many false positives), understaffing (no one reviewing the console at 2 AM), and underdocumentation (event logs exist but compliance evidence packages do not). Managed SIEM, delivered as part of SENTRY, solves all three: the platform is tuned by security engineers who operate it full time, it is staffed 24/7, and compliance evidence generation is built into the workflow.
Deep-dive comparisons live in the SENTRY spoke pages below. This hub frames the program; the spokes go further on pricing architecture, platform comparisons, and vertical-specific configurations.
The Armorstack SENTRY Approach: Converged, Deterministic, Always-On
Armorstack is not an MSSP. Armorstack is a Managed Intelligence Provider — a distinction that reflects a fundamentally different operating model. Where MSSPs monitor and notify, SENTRY detects, investigates, responds, and continuously improves. Where point-product vendors sell you tools, SENTRY delivers outcomes: confirmed threat containment, compliance evidence, and a measurable reduction in your organization’s exposure window.
SENTRY MDR is delivered from a 24/7 Security Operations Center staffed by 100+ security professionals with domain expertise across your regulated vertical. The program spans five integrated capabilities that most organizations currently operate as separate, disconnected functions.
24/7 SOC Monitoring
Continuous monitoring of your environment — cloud, on-premises, hybrid, and OT/IT — with analyst coverage across all three shifts, 365 days a year. No coverage gaps. No “we’ll look at it Monday morning.” The SENTRY SOC maintains eyes on your environment during the precise hours when threat actors are most active.
Managed SIEM
Security Information and Event Management, fully managed. Armorstack engineers handle deployment, tuning, log source onboarding, rule development, and ongoing optimization. Your team receives the value of a mature SIEM without the operational burden of running one. Log retention and event correlation are configured to your compliance framework’s specific requirements — HIPAA audit log mandates, CMMC AU control families, PCI-DSS log retention — from day one.
Managed Detection and Response
When the SIEM surfaces an alert, SENTRY analysts investigate it. Real investigation, not auto-escalation. Analysts apply threat intelligence context, behavioral baselines, and knowledge of your specific environment to determine whether an alert represents a genuine threat. When it does, SENTRY executes a documented response: host isolation, credential invalidation, blocking rules, and coordinated remediation — with your team in the loop at every step.
Proactive Threat Hunting
Reactive detection finds threats that trigger rules. Proactive threat hunting finds threats that have not triggered rules yet — adversaries who have established persistence and are moving laterally without generating obvious alerts. SENTRY threat hunters operate on a hypothesis-driven model, actively searching your environment for indicators of compromise that automated detection has not flagged. This is the capability that separates a mature security program from a tool-monitoring operation.
Dark Web Monitoring
Your organization’s credentials, sensitive data, and intellectual property may already be circulating in criminal markets. SENTRY dark web monitoring continuously scans threat actor forums, paste sites, criminal marketplaces, and closed communities for evidence of your organization’s data — employee credentials, customer records, domain references — and delivers actionable intelligence before that data is weaponized in an attack against you.
Incident Response
When a confirmed incident requires escalation beyond active containment, SENTRY’s incident response capability provides structured, documented response from seasoned practitioners. Forensic analysis, root cause determination, regulatory notification support, and post-incident review are delivered under your existing SENTRY engagement — not as an unexpected billable event from an unfamiliar team that has never seen your environment before.
The Observability Gap: Why AI Changes the Threat Landscape for Regulated Industries
Every organization in your industry is adopting AI tooling. The problem is that enterprise AI deployment is dramatically outpacing security teams’ ability to monitor AI behavior — what Armorstack calls the Observability Gap. AI models operating in clinical, financial, and operational contexts introduce novel attack surfaces: prompt injection, model inversion, shadow AI usage, and LLM supply chain compromise. SENTRY incorporates AI security observability — monitoring AI system behavior, detecting anomalous model outputs, and flagging shadow AI adoption — as part of the detection program, not as an add-on purchased later. As your organization’s AI footprint grows, SENTRY grows with it.
Cyber-Physical Convergence: SENTRY + CITADEL
Most MDR providers monitor your network. Armorstack monitors your building, too. Through the converged SENTRY + CITADEL program, physical security telemetry — access control events, video analytics anomalies, fire alarm system status, and mass notification triggers from CITADEL — feeds directly into the SENTRY SOC. A suspicious after-hours access event correlated with anomalous network behavior is a threat indicator that no network-only MDR provider can see. Cyber-physical correlation is the detection capability that genuinely converged security enables. No single-portfolio provider offers it.
This is deterministic observability: a documented, auditable monitoring program that covers your entire attack surface — logical and physical — rather than the subset of it that happens to generate network logs.

SENTRY MDR for Regulated Verticals
Mid-market organizations in regulated industries face a specific combination of threat exposure and compliance obligation that general-purpose MDR providers are not built for. SENTRY is purpose-built for these environments.
Healthcare
The compliance driver: HIPAA requires covered entities and business associates to implement audit controls, monitor access to electronic protected health information (ePHI), and detect and respond to security incidents. The HIPAA Security Rule’s Technical Safeguard requirements — specifically the Audit Controls standard (§ 164.312(b)) and the Transmission Security standard — require documented, continuous monitoring capability that most healthcare organizations currently address only partially.
The threat driver: Healthcare is the most-targeted sector for ransomware globally. EHR systems, medical devices, and clinical networks present attack surfaces that traditional IT security tools are not designed to monitor. Patient safety is directly affected when clinical systems are disrupted. The financial and regulatory cost of a healthcare breach — OCR investigation, breach notification, potential civil monetary penalties, and reputational damage — significantly exceeds the cost of a mature detection program.
SENTRY delivers: HIPAA-aligned audit log management, continuous monitoring of ePHI access patterns, anomaly detection for unusual data access that may indicate insider threat or credential compromise, and incident response documentation structured for OCR review. CITADEL Care integration adds resident-safety and nurse-call event correlation for senior living and long-term care environments.
MDR for Healthcare — full page
Financial Services
The compliance driver: Financial institutions operating under PCI-DSS, GLBA, and state-level privacy regulations face specific continuous monitoring requirements. PCI-DSS Requirement 10 mandates log monitoring and review; Requirement 11 requires regular testing of security controls. GLBA’s Safeguards Rule requires a written information security program with ongoing risk assessment and monitoring components. Federal banking examiners increasingly treat the absence of a documented detection and response capability as a finding.
The threat driver: Financial institutions are targets for account takeover, business email compromise, wire fraud, and increasingly for ransomware campaigns timed to coincide with quarter-end or regulatory filing periods when disruption causes maximum pressure. Insider threats — both malicious and accidental — represent a disproportionate risk in financial services environments where privileged access is broad and monitoring of that access is inconsistent.
SENTRY delivers: PCI-DSS Requirement 10-aligned log monitoring and review, anomalous privileged access detection, dark web monitoring for customer account credential exposure, and exam-ready documentation that demonstrates a continuous monitoring program to federal examiners.
Defense Contractors
The compliance driver: CMMC 2.0 Level 2 requires compliance with NIST SP 800-171, which includes the Audit and Accountability (AU) and Incident Response (IR) control families. AU.3.045 requires alerting on audit log failures. AU.3.046 requires reviewing audit logs for indicators of inappropriate activity. IR.2.092 requires tracking, documenting, and reporting incidents. IR.2.093 requires testing the incident response capability. These are not aspirational controls — they are required for contract award and renewal under CMMC, and third-party assessment organizations (C3PAOs) will test them.
The threat driver: Defense Industrial Base (DIB) contractors are among the most actively targeted sectors by nation-state threat actors, specifically because they hold Controlled Unclassified Information (CUI) that represents strategic intelligence value. Advanced persistent threat (APT) groups targeting the DIB are well-resourced, patient, and skilled at establishing persistence without triggering commodity detection tools. Threat hunting — not just reactive alerting — is the only detection approach that reliably surfaces these actors.
SENTRY delivers: CMMC-aligned continuous monitoring covering AU and IR control families, CUI access monitoring and anomaly detection, nation-state threat intelligence integration, and C3PAO assessment documentation. Threat hunting frequency and documentation are structured to satisfy CMMC IR.3.098 (test incident response).
SOC for Defense Contractors — full page
Manufacturing
The compliance driver: Manufacturers who are DIB contractors face CMMC obligations. Manufacturers in sectors such as food and beverage, pharmaceuticals, and chemicals face FDA cybersecurity guidance for OT environments. All manufacturers operating SCADA or ICS infrastructure face NIST SP 800-82 guidance for industrial control system security, increasingly cited by cyber insurance underwriters as a baseline expectation.
The threat driver: Manufacturing is one of the most-targeted sectors for ransomware globally, and the consequences of an OT environment disruption are severe: production shutdown, safety incidents, supply chain disruption, and in some cases physical damage to equipment. The OT/IT convergence that has driven manufacturing efficiency has also expanded the attack surface dramatically — and OT environments generate telemetry that traditional IT-focused SIEM platforms were not built to ingest or correlate.
SENTRY delivers: OT/IT converged monitoring, ICS/SCADA event ingestion and anomaly detection, network segmentation monitoring, and threat hunting calibrated for the lateral movement patterns characteristic of manufacturing-targeted ransomware groups. CITADEL Gate integration adds physical access control event correlation for OT facility environments.
How SENTRY MDR Maps to Continuous Monitoring Requirements
The table below identifies the specific monitoring and detection controls that SENTRY addresses within each major compliance framework. This is not a complete compliance map — SENTRY addresses detection and response requirements, not the full framework. Your VERITY vCISO engagement covers the complete compliance posture. This table is intended to help security and compliance teams quickly identify where SENTRY’s detection program produces evidence that supports audit and examination requirements.

Why Armorstack SENTRY
Managed Intelligence Provider — Not a Tool Vendor, Not a Monitoring Reseller
Armorstack is a Managed Intelligence Provider. This is not a rebrand of managed security services — it reflects a different operating model. SENTRY does not hand you alerts. SENTRY delivers outcomes: confirmed threat containment, compliance evidence, and a documented security program that matures over time. The distinction matters because when a threat actor is in your environment at 3 AM on a Saturday, the question is not whether an alert fired. The question is whether someone investigated it, confirmed it, and acted on it before business opened Monday morning.
100+ Security Professionals Across 9 Service Lines
Armorstack’s team of 100+ technical experts and security professionals brings domain depth that a typical managed security provider cannot replicate. SENTRY analysts are not generalists monitoring an undifferentiated alert queue. They operate alongside a VERITY advisory team (vCISO, vCIO, compliance), a CORE infrastructure team (cloud, identity, network), and a CITADEL physical security team — the same organization that monitors your cameras, access control, and building systems is also monitoring your network and endpoints. That operational context changes what analysts can see and how quickly they can act.
Converged Cyber-Physical Security
Armorstack is, to our knowledge, the only Managed Intelligence Provider in the Wisconsin and upper-midwest market that delivers genuine cyber-physical convergence as a standard program capability — not as a theoretical integration. SENTRY and CITADEL are built by the same organization and operated by the same team. Physical access events, video analytics anomalies, and building system telemetry feed the same SOC that monitors your network. The Observability Gap closes when the program covers the complete attack surface, not just the logical one.
The 90-Day Proof — No Long-Term Contract Required to Start
Armorstack offers a structured 90-day program designed for organizations that want to validate MDR outcomes before committing to a multi-year engagement. Over 90 days, SENTRY deploys, tunes, and operates the full detection and response program in your environment. You will receive threat hunting results, incident documentation, compliance evidence, and a complete program review at the end of the period. If SENTRY delivers, you continue. There is no pressure and no obligation to sign before you have seen the results.
This reflects a straightforward conviction: a mature MDR program produces measurable outcomes within 90 days. If it does not, you should not pay for it long-term.

Frequently Asked Questions About MDR and SOC-as-a-Service
What is managed detection and response (MDR), exactly?
Managed detection and response (MDR) is an outsourced security service that combines continuous monitoring technology — typically a SIEM, EDR platform, and threat intelligence feeds — with a team of human security analysts who investigate alerts and actively respond to confirmed threats. The “response” component is what separates MDR from a tool subscription or a basic monitoring alert service. When SENTRY detects a confirmed threat in your environment, analysts execute containment actions — isolating affected hosts, invalidating compromised credentials, applying blocking rules — rather than sending an email and waiting for your team to respond. MDR is appropriate for any organization that needs security operations coverage it cannot staff internally, particularly those in regulated industries with continuous monitoring requirements.
What is the difference between MDR and an MSSP?
The distinction is operationally significant. A managed security services provider (MSSP) typically provides monitoring and alerting — they watch your environment and notify you when something looks suspicious. The investigation and response responsibility remains with your team. An MDR provider investigates and responds on your behalf. When SENTRY identifies a potential threat, analysts investigate it, determine whether it is a confirmed incident, and execute a documented response — containment, remediation guidance, and post-incident review — without requiring your team to act first. For organizations with limited internal security staff, or for regulated industries where the gap between detection and containment directly affects compliance exposure, the MDR model is materially different from the MSSP model. Armorstack does not operate as an MSSP. Armorstack is a Managed Intelligence Provider — a program-led, outcome-oriented security partner.
How much does SOC-as-a-Service cost?
SOC-as-a-Service cost is driven by several factors: the size and complexity of the environment being monitored (number of endpoints, log sources, cloud workloads, OT assets), the compliance frameworks requiring evidence generation, the desired threat hunting frequency, and the level of incident response capability included. Mid-market SOC-as-a-Service programs vary meaningfully based on these variables — which is why published price lists for this type of engagement are almost always misleading. A price built around a generic environment will be either too high or too low for your specific configuration. Armorstack scopes every SENTRY engagement individually. The best starting point is a scoped assessment, which maps your environment to the SENTRY program and produces a specific proposal. You can also start with the 90-Day Proof to validate the program before committing to a longer-term engagement. Request a scoped assessment.
Does my organization actually need 24/7 SOC monitoring?
The honest answer depends on your threat profile and your compliance obligations — but the threshold for “yes” is lower than most mid-market organizations assume. If your organization operates in healthcare, financial services, manufacturing, or the defense industrial base, continuous monitoring is either required (by regulation) or assumed (by your cyber insurance carrier and your enterprise customers). Beyond compliance, the operational reality is that threat actors actively target off-hours. Mandiant and CrowdStrike incident data consistently show that intrusions escalate most aggressively when detection and response capacity is thinnest. If your security team goes home at 5 PM, adversaries know that. Organizations that have experienced a significant incident consistently report that the dwell time — the gap between initial access and detection — occurred almost entirely during hours when no one was actively monitoring. 24/7 SOC monitoring closes that window.
Does MDR satisfy HIPAA continuous monitoring requirements?
SENTRY MDR is designed specifically to address the HIPAA Security Rule’s technical safeguard requirements for audit controls (§ 164.312(b)) and security incident procedures (§ 164.308(a)(6)). The program provides continuous monitoring of ePHI access, anomaly detection on access patterns, audit log management and retention, and documented incident response capability. However, HIPAA compliance is a program, not a single tool or service — it encompasses physical safeguards, administrative safeguards, and organizational requirements that SENTRY does not cover in isolation. Armorstack’s VERITY advisory team provides vCISO services that map the complete HIPAA compliance posture and document how SENTRY’s detection outputs satisfy the audit control requirements. SENTRY is a critical component of HIPAA compliance; it is not a complete HIPAA program. See the SENTRY MDR for Healthcare page for a detailed mapping.
Does MDR satisfy CMMC 2.0 continuous monitoring requirements?
SENTRY MDR addresses the CMMC 2.0 Level 2 Audit and Accountability (AU) and Incident Response (IR) control families, which are among the most frequently cited gaps in CMMC readiness assessments. Specifically, the program addresses AU.3.045 (audit log failure alerting), AU.3.046 (audit log review for inappropriate activity), IR.2.092 (incident tracking and documentation), and IR.2.093 (incident response capability testing). CMMC compliance is a 110-practice program — SENTRY addresses the detection and response subset. Organizations pursuing CMMC Level 2 should engage Armorstack’s VERITY advisory team for a complete System Security Plan (SSP) and Plan of Action and Milestones (POA&M) that maps all practices, with SENTRY evidence integrated into the audit package. See the SENTRY SOC for Defense Contractors page. See the full CMMC readiness program.
Should we build an in-house SOC or use MDR?
For most mid-market organizations — those with under 5,000 employees, without a dedicated security team of ten or more, and without the budget to recruit and retain multiple experienced SOC analysts — the in-house SOC path produces worse security outcomes at significantly higher cost. The fully-loaded cost of a properly staffed, 24/7, in-house SOC — covering three shifts, tool licensing, SIEM engineering, threat intelligence, and leadership — exceeds the cost of a mature MDR program for most mid-market configurations, and still leaves the organization exposed to the talent retention risk that makes in-house SOC programs degrade over time. MDR provides immediate access to a team that is already trained, already operating a tuned SIEM, and already ingesting your vertical’s specific threat intelligence. The 90-Day Proof is designed specifically for organizations evaluating this decision: you will have concrete program outcomes in hand before committing to either path. Learn about the 90-Day Proof.
What is the 90-Day Proof and how does it work?
The 90-Day Proof is Armorstack’s structured program for organizations that want to validate MDR outcomes before committing to a long-term engagement. Over 90 days, SENTRY deploys and operates the full detection and response program in your environment. At the end of the period, you receive a complete program review: threat hunting results, incident documentation (if applicable), compliance evidence generated, detection coverage assessment, and a program roadmap. There is no obligation to continue after the 90-day period. The program exists because Armorstack’s position is straightforward: a mature MDR program produces measurable outcomes within 90 days, and you should be able to evaluate those outcomes before you commit. See how the 90-Day Proof works →
