How to Choose an IT Outsourcing Provider: 10 Criteria That Actually Matter

For regulated industries, the provider must hold FSTEC TZKI license. ISO 27001 certification is a strong positive signal for security practices.

Critical incidents (P1): 15–30 min response, 4h resolution. Anything weaker is unacceptable for production systems. Verify SLA with references — ask about actual recent P1 incidents.

Can an engineer be physically present at your office within 2 hours? Remote-only support is insufficient for hardware failures, network outages, or physical security incidents.

Do engineers handle customer data? Background checks, NDA, and access control policies should be standard. Ask for their security onboarding procedures.

Who do you call when the helpdesk fails you? There should be a named account manager and a clear escalation path to technical leadership.

Fixed monthly fee with defined scope is preferable to time-and-materials for predictable budgeting. Watch for ambiguous scope definitions that allow scope expansion billing.

References from companies of your size and industry are more valuable than enterprise logos. Request contacts and actually call them.

Does the provider have certified specialists for your specific infrastructure (Cisco/HP/Dell, Windows/Linux, specific applications)? Generic IT providers often lack depth.

How do you transition away from this provider? All documentation, credentials, and configurations must be yours — not held by the provider.

A provider that goes bankrupt takes your infrastructure knowledge with it. Check company age, client base size, and ask about key person dependency.
