Wayne County organizations need information technology that keeps teams productive and security that stays vigilant long after business hours. Dominant Systems provides managed IT services and managed security for small and mid-sized businesses across Wayne County, including Detroit, Dearborn, Livonia, Canton, Plymouth, Romulus, Westland, Southgate, and surrounding communities. Our focus is straightforward: reduce downtime, control risk, and give you clear accountability with a predictable support model.

On the IT side, our managed services program delivers ongoing maintenance and support for your computers and network for a fixed monthly fee. We handle proactive monitoring, patch management, help desk support, and onsite service when needed—so issues get resolved quickly and recurring problems are addressed at the root cause. We also assist with projects like PC refreshes, server deployments, network upgrades, Wi-Fi improvements, and secure remote access, helping you modernize without disruption.

We support both on-premises and cloud environments, and we’re comfortable working across a range of platforms—including Windows Server, Hyper-V, Proxmox, UNIX/Linux, and VMware—so your infrastructure can evolve based on what fits your business, budget, and compliance needs. Reliable backup and disaster recovery is also a core part of business continuity, and we help organizations design, maintain, and test recovery plans so you’re not guessing during an outage, accidental deletion, or ransomware event.

For cybersecurity, we use layered protection to cover the most common attack paths. Next-generation firewalls and network security hardening help stop threats before they enter your environment. Endpoint protection helps defend laptops, desktops, and servers—especially against phishing-driven malware and ransomware. On top of those foundational layers, we add 24×7×365 SOC-level coverage with MDR (Managed Detect & Respond). MDR combines endpoint telemetry, threat hunting, and human investigation to identify suspicious behaviors, validate true incidents, and guide response actions—often including containment steps such as isolating affected devices and recommending credential resets and hardening.

Identity is now a primary target, so we also offer ITDR/IDTR (Identity Threat Detection & Response) to help protect 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 activity is confirmed, response actions can include disabling compromised accounts, revoking sessions, removing rogue apps, and reversing abusive email settings—reducing the chance that a single stolen credential becomes a major incident.
