Managed IT and cybersecurity services for mid-market healthcare and life sciences
Harbor IT operates a full-stack managed services business anchored in cybersecurity — their proprietary SIEM code and adoption of SentinelOne + ThreatLocker signal a security-first stack rather than a commodity MSP. Current hiring is sales-heavy (3 roles) with parallel pushes into life sciences and energy verticals, suggesting deliberate market expansion beyond their healthcare core. Client churn and contract renewal challenges appear in their project list alongside aggressive go-to-market builds for new verticals — indicating they're scaling beyond their traditional install base.
