Livingston County businesses need technology that’s dependable every day—and security that stays alert when attackers are most active. Dominant Systems provides managed IT services and managed security for small and mid-sized organizations throughout Livingston County, including Brighton, Howell, Pinckney, Hartland, Fowlerville, and the surrounding area. We help you reduce downtime, tighten security, and gain clear accountability with a predictable plan and a team you can reach.

Our managed IT services are designed to prevent recurring issues before they interrupt your work. We provide responsive help desk support, proactive monitoring, patch management, and onsite service when needed. We also handle the operational details that keep your environment organized and scalable: Microsoft 365 administration, user onboarding and offboarding, device setup, network and Wi-Fi management, secure remote access, and documentation that makes troubleshooting faster and less disruptive. When it’s time to upgrade, we can assist with PC refreshes, server and storage modernization, Wi-Fi improvements, and network projects—planned and executed to minimize downtime.

Many Livingston County organizations run a blend of on-premises and cloud systems, and we support both. Whether you rely on Windows Server, Hyper-V, Proxmox, UNIX/Linux, or VMware, we help you choose the right approach based on performance, cost, and compliance requirements—not a one-size-fits-all template. Business continuity is part of stability, so we also implement backup and disaster recovery strategies and validate them with routine restore testing. That means you’re prepared for outages, accidental deletions, hardware failures, and ransomware events.

Security is built in through layered protection that covers the most common attack paths. We deploy and manage next-generation firewalls and harden your network to reduce exposure. We protect laptops, desktops, and servers with modern endpoint security to help stop phishing-driven malware and ransomware. On top of those foundations, we offer 24×7×365 MDR (Managed Detect & Respond), which uses endpoint telemetry, threat hunting, and human investigation to identify suspicious behavior, confirm real incidents, and guide rapid response—often including containment steps like isolating devices and recommending credential resets and system hardening.

Because identity is now a primary target, we also provide ITDR/IDTR (Identity Threat Detection & Response) for Microsoft 365 and Entra ID. ITDR monitors sign-ins, session behavior, mailbox and OAuth abuse, and risky configuration changes to detect account takeover attempts, malicious inbox rules, MFA fatigue attacks, and token/session misuse. When an incident is confirmed, response actions can include revoking sessions, disabling compromised accounts, removing rogue apps, and reversing abusive email settings to stop attackers quickly.

If you want reliable IT support and always-on security without building a large internal team, contact us today. We’ll review your environment, identify quick wins, and outline a right-sized plan for stronger IT and security across Livingston County.
