What do IT services cover?
IT services span everything a business needs to run technology: help desk and end-user support, monitoring and maintenance, cybersecurity, backup and recovery, cloud, networking, and strategy. They can be delivered by an internal team, an outside provider, or a mix. The shift toward outside delivery is decisive: Softura reports the global IT outsourcing market reached $638.65 billion in 2026, with 92% of the largest 2,000 companies outsourcing IT services.
How are IT services delivered?
| Model | What it is |
|---|---|
| In-house | Your own IT team |
| Managed services | A provider runs IT ongoing for a monthly fee |
| Project-based | A firm delivers a specific engagement |
| Co-managed | Internal team plus a provider filling gaps |
Most businesses blend models, keeping strategy in-house while outsourcing coverage and specialized skills.
Why are businesses outsourcing IT services?
The reason has changed. Cost reduction as the primary driver fell from 70% in 2020 to just 34% in 2026, replaced by access to talent and speed to market. 87% of IT leaders now use outsourcing to accelerate AI adoption. Cybersecurity, once one of the least-outsourced functions, is now the most-outsourced, tied with infrastructure at 72%, because the skills are hard to hire and the stakes keep rising (Procurement Tactics tracks the shift).
How do you choose an IT services provider?
Match the model to the need: a managed provider for ongoing operations, a consultant for a project or decision, or co-managed if you have a team that needs backup. Weigh response commitments, security depth, and industry references over headline price. With four in five companies outsourcing or planning to, the question is which partner fits, not whether to use one.
