Which IT functions can businesses outsource?

Outsourcing IT functions means assigning defined technology responsibilities to an external provider rather than managing every task within the organisation. A business can outsource one specialist function, such as security monitoring, or combine several services into a managed arrangement. The appropriate model depends on the systems involved, the skills available internally, regulatory obligations and the level of control the organisation needs to retain.

Service desk and user support

Many businesses outsource the day-to-day assistance that employees need to use technology effectively. This can include diagnosing software faults, resolving access issues, supporting email and collaboration tools, helping users connect to business systems and handling device-related problems. The provider may record, prioritise and track requests through a ticketing process, while agreed escalation routes determine which issues require internal input.

This function is suitable for organisations that have limited internal IT capacity or want their in-house team to focus on projects, operations or business applications. The scope should define which users, devices and applications are supported, as well as which requests remain the responsibility of an internal team or software supplier.

Workplace and device management

An external provider can manage the technology used by employees, including computers, mobile devices, operating systems, standard applications and security settings. Typical activities include configuring new devices, applying updates, managing user permissions, enforcing configuration policies and removing access when someone leaves the organisation.

Device management is particularly relevant where employees work across multiple locations or use a mixture of office and remote arrangements. A clear division of responsibility is important: the agreement should state who owns the equipment, who approves software installations, how personal devices are treated and what happens when a device is lost, damaged or replaced.

Infrastructure management

Businesses may outsource the administration of servers, networks, storage, identity systems and other core infrastructure. The work can include maintaining configurations, monitoring capacity, applying patches, managing accounts, documenting the environment and planning upgrades. Infrastructure support may cover equipment on the organisation’s premises, hosted systems or a combination of both.

Outsourcing this area does not remove the need for internal ownership. The business should retain appropriate administrative authority, asset records and documentation, while the provider carries out agreed operational tasks. This helps prevent dependence on undocumented knowledge and makes future changes or supplier transitions more manageable.

Cyber security operations

Security functions can be outsourced where an organisation does not have the specialist expertise to assess and respond to threats internally. Services may include security policy development, vulnerability assessment, endpoint protection, identity and access controls, security event monitoring, phishing awareness and incident response planning.

The important distinction is between technology that supports security and the governance decisions that remain with the business. The organisation must still determine its risk tolerance, approve access principles, decide which information is most sensitive and authorise significant changes. An outsourced provider can supply expertise, monitoring and practical controls, but accountability for business decisions remains with the organisation.

Cloud administration

Cloud-related responsibilities can be divided between the cloud platform, the provider and the customer. An outsourced IT partner may manage cloud identities, permissions, virtual resources, configuration, migration activities, cost controls, backup arrangements and connections between cloud and on-premises systems.

Businesses should identify exactly which platform settings and workloads are included. Cloud services are not automatically secure or correctly configured simply because they are hosted by a third party. Access privileges, retention rules, encryption requirements, recovery arrangements and ownership of data should be documented before responsibility is transferred.

Backup, recovery and continuity technology

Backup management is another function that can be delegated. This may involve selecting protected data, configuring backup schedules, checking whether jobs complete, storing copies separately and testing restoration procedures. Providers can also help prepare technical recovery plans for events such as hardware failure, accidental deletion, ransomware or loss of access to a key system.

A backup service should not be judged solely by whether a copy exists. The business needs to understand what can be restored, how restoration is authorised, how long information is retained and whether recovery has been tested. Business owners should also identify which processes are most important so that technical recovery priorities match operational priorities.

Connectivity and communications

An organisation can outsource the management of its internet connectivity, site-to-site links, wireless networks, remote access and related communications infrastructure. A provider may assess requirements, coordinate installations, manage network equipment, review performance and help maintain secure connections between offices, users and cloud systems.

This can be useful for multi-site organisations, where consistent configuration and central oversight are harder to maintain internally. The service description should distinguish between managing the network and supplying the underlying connection, because faults involving a telecommunications carrier may require a separate escalation route.

IT projects and strategic functions

Outsourcing does not have to be limited to routine operations. External specialists can support technology planning, office moves, system migrations, infrastructure upgrades, software implementation, security improvement programmes and technical due diligence. Some businesses also use an outsourced adviser for technology roadmaps, budgeting, supplier evaluation and prioritising investment.

Project-based support is often appropriate when the organisation needs expertise that is not required permanently. The scope should define the intended outcome, dependencies, decision-makers, acceptance criteria and responsibility for ongoing maintenance after the project is completed.

Fully outsourced, co-managed or specialist support

There are three common approaches:

• Fully managed: the provider takes responsibility for a defined set of operational functions, with the business retaining governance and approval authority.
• Co-managed: internal staff and the provider share duties, often with the provider supplying additional capacity or specialist knowledge.
• Specialist outsourcing: the business retains general IT ownership but delegates a focused area, such as security, cloud migration or backup management.

These models can also be combined. For example, internal staff might manage business applications while an external partner manages infrastructure and security controls. The main risk is not choosing the wrong label but leaving responsibilities unclear.

How to decide which functions to outsource

Before selecting functions, assess the organisation’s current capability, the sensitivity of its information, the effect of an outage, the complexity of its technology estate and the level of internal involvement required. Functions that depend on specialist tools or continuous technical oversight may be suitable for external management, while activities closely tied to commercial decisions or unique business processes may need to remain internal.

For each proposed function, document:

• the systems, users and locations covered;
• the tasks the provider will perform and those retained by the business;
• approval requirements for access, changes and expenditure;
• how incidents, security events and major decisions are escalated;
• what information, documentation and administrative access each party receives; and
• how performance, risk, reporting and service changes will be reviewed.
