IT Monitoring: in-house or outsource to an MSP?

Managing an IT estate in 2026 requires skills, tools and availability. Should you build an in-house team or hand it over to an MSP? The answer depends on your size, criticality and growth stage.

In-house option

Pros

• Deep institutional knowledge of the business
• Fast reactivity, no "external provider" chasing
• Can take on side projects (business apps, internal dev)
• Long-term costs potentially lower above a certain size

Cons

• Fixed salary + benefits, even on low-activity months
• Hard to find and keep senior sysadmins
• Vacation / sick leave / resignation = critical gaps
• Below ~50 people, the role is often part-time only

MSP option

Pros

• Fixed monthly fee, often cheaper under 50 people
• 24/7 availability (or 5x8 per the contract)
• Access to a wide team with varied expertise
• No HR management (vacations, raises, training)
• Up-to-date tools (RMM, PSA, EDR)

Cons

• Dependent on vendor availability
• Risk of lower-tier support unless specified in the contract
• Less deep business knowledge
• Switching costs if the relationship goes bad

Which to pick based on your size?

Under 20 people

MSP recommended. An in-house sysadmin would be seriously underused.

20-80 people

Hybrid. A junior IT internal person for daily user support, backed by an MSP for monitoring, patch management and incidents.

80-200 people

In-house with escalation. A full in-house team of 2-3 people, backed by an MSP for third-level support and specialized projects.

200+ people

Full in-house, structured by expertise domain (network, systems, security, workstations), with specialized vendors for niche needs.

The right tooling in both cases

Whether in-house or outsourced, the fleet must be monitored by an RMM. For an MSP: a multi-tenant tool with ticketing and reports (like WezOps). For an in-house team: a single-tenant tool with per-site segmentation.
