STACK Cybersecurity

Overview

About

STACK Cybersecurity is a Livonia, Michigan-based managed security and managed IT services provider serving defense contractors, healthcare, legal, accounting, and manufacturing clients throughout Metro Detroit and across the nation. Founded in 2006 as AM Data Service and rebranded to reflect its security-first mission, the company is led by CEO Rich Miller and staffed by a team of 10 to 49 cybersecurity engineers and IT professionals operating from Schoolcraft Road in Livonia. STACK holds the rare distinction of being a CMMC Registered Practitioner Organization, a designation uncommon among managed service providers that authorizes the firm to provide expert consultation on Cybersecurity Maturity Model Certification requirements — including comprehensive gap assessments, remediation planning and implementation, and pre-assessment preparation for defense contractors navigating DFARS requirements. The company is SOC 2 Type II certified, demonstrating audited controls over the security, availability, and confidentiality of the systems it manages for clients. As both an MSP and MSSP, STACK delivers managed IT services — help desk, monitoring, infrastructure management — alongside managed security services such as continuous threat monitoring, vulnerability management, and incident response, giving clients a single accountable partner for technology operations and cyber defense. Workforce development is part of the firm's identity: STACK operates a Department of Labor-registered Cyber Defense Incident Responder apprenticeship program, building the next generation of security talent through hands-on training. The company is a certified veteran-friendly employer and was named a 2026 Michigan 50 Companies to Watch recipient, reflecting both its growth and its community standing. For Metro Detroit organizations in regulated or targeted industries — particularly small manufacturers in the defense supply chain that lack internal resources to navigate CMMC on their own — STACK Cybersecurity offers specialized, practical security expertise without overwhelming budgets, backed by the certifications and credentials that auditors and contracting officers require. The CMMC Registered Practitioner Organization designation is the credential that sets STACK apart: RPO status remains uncommon among managed service and security providers because it demands proven federal contracting expertise, rigorous staff training, and strict ethical standards. Under specialized practice leadership, the firm guides defense contractors — especially smaller manufacturers without internal compliance resources — through gap assessments, remediation planning and implementation, and pre-assessment preparation, translating dense DFARS requirements into practical, budget-conscious action plans. SOC 2 Type II certification provides independent assurance over the security, availability, and confidentiality controls governing the systems STACK manages. Day-to-day, the company operates as both MSP and MSSP: managed IT services keep infrastructure, help desk, and end-user computing running, while managed security services deliver continuous monitoring, vulnerability management, and incident response. Workforce development is institutionalized through the Department of Labor-registered Cyber Defense Incident Responder apprenticeship, a two-year program building hands-on security talent for an industry facing chronic shortages. Recognition has followed: the firm earned a global industry award for advancing diversity in technology leadership, holds certified veteran-friendly employer status, and was named a 2026 Michigan 50 Companies to Watch recipient. For Metro Detroit organizations in defense, healthcare, legal, accounting, and manufacturing — particularly subcontractors navigating CMMC — STACK Cybersecurity combines rare credentials, practical delivery, and a talent pipeline that keeps its security practice sharp.
