Rexus Group Tech Stack

IT infrastructure consulting and managed services across vendor-agnostic platforms

IT Services and IT Consulting Wilmington, Delaware 51–200 employees Founded 2016 Privately Held

Rexus Group operates as a vendor-agnostic IT infrastructure consulting and managed services firm, built on a core stack of Windows, Microsoft 365, ServiceNow, Jira, and Cisco networking gear. Active projects cluster heavily around network modernization (ACI fabric migrations, L3Out configs, Cisco MDS upgrades) and enterprise backup/protection (Rubrik deployments), while pain points center on SLA delivery in security-sensitive, compliance-heavy environments. Senior-heavy hiring (6 of 12 active roles) weighted toward engineering suggests the firm is scaling delivery capability for complex infrastructure migrations rather than expanding sales.
