Augmentation, Not a Takeover
Most mid-market organizations don’t need to outsource IT entirely — they need to close specific gaps: after-hours and weekend coverage, a 24/7 NOC watching the network while your team sleeps, specialized security or compliance skills your generalist admins don’t have time to build, or simple surge capacity during a migration or audit.
Co-managed IT is Armorstack’s answer to that: we plug CORE Baseline’s unified monitoring, ticketing overflow, and NOC escalation into your environment as a reinforcement layer. Your internal IT team keeps its seat at the table, its institutional knowledge, and control over strategic decisions — we own the tiers, hours, and specialist coverage they hand off to us.
Not the Same as Fully Managed IT
If you want a single outsourced partner running 100% of your IT operations, see our fully managed IT services instead. Co-managed is built specifically for organizations that already have an internal team and want to keep it.
Common Co-Managed Coverage Models
Every co-managed engagement is scoped to the gap you actually have — not a one-size-fits-all handoff.
After-Hours & Weekend NOC
Your team owns business hours; Armorstack’s NOC and CORE Baseline severity clock take over nights, weekends, and holidays so nothing waits until Monday.
Tier 2/3 Escalation Bench
Your help desk handles Tier 1. Escalations that need deeper network, security, or systems expertise route to Armorstack engineers instead of stalling.
Security & Compliance Specialists
HIPAA, CMMC, PCI-DSS — frameworks your generalist admins don’t live in every day. We supply the specialist coverage without you hiring a dedicated headcount.
Project & Migration Surge Capacity
Cloud migrations, M&A integrations, office moves — short bursts of extra engineering hands without a permanent headcount add.
Unified Monitoring Layer
CORE Baseline’s telemetry plane sits alongside your existing tools (or replaces the ones that aren’t earning their license fee) so nothing falls in a gap between vendors.
Vendor & Escalation Management
When an ISP, SaaS vendor, or hardware OEM needs to be chased for a fix, we carry that call so your internal team isn’t on hold with a vendor support line.
