The IT To-Do List Every Business Should Complete Before Christmas

For many businesses, the Christmas period means quieter offices, reduced staffing and systems left running with minimal oversight.

Unfortunately, it’s also one of the most common times for IT issues and cyber incidents to occur, often because no one is around to spot problems early or respond quickly.

A small amount of preparation before you log off for the festive break can prevent unnecessary stress, disruption and costly downtime in the new year.

Here are four essential IT checks every business should complete before Christmas.

1. Make sure everything is properly backed up

Backups are only useful if they’re working and if they can actually be restored.

Too often, businesses assume backups are running as expected, only to discover after an incident that data is missing, corrupted or inaccessible.

Before the break, it’s worth:

• Confirming backups are running on schedule
• Checking that critical systems and data are included
• Testing a restore to ensure files can be recovered if needed

A verified backup can be the difference between a minor inconvenience and a major business interruption.

2. Update and patch systems before shutdown

Outdated software remains one of the easiest ways for cybercriminals to exploit business systems.

When offices are closed for extended periods, unpatched vulnerabilities can sit exposed for days or weeks without being noticed.

To reduce risk:

• Apply pending operating system and software updates
• Ensure security patches are installed across all devices
• Replace or isolate any unsupported systems

Updating before the festive shutdown helps close known security gaps and reduces the likelihood of attacks during quieter periods.

3. Review access and out-of-office security

Christmas often brings temporary changes to staff access, whether through leavers, contractors or shared inboxes used for holiday cover.

These changes can unintentionally create security risks if access isn’t reviewed.

Before logging off:

• Remove access for leavers or temporary staff
• Review shared accounts and inbox permissions
• Enable multi-factor authentication (MFA) wherever possible

Even simple access checks can significantly reduce the risk of unauthorised access while teams are away.

4. Know who to call if something goes wrong

If an IT issue occurs during the festive break, knowing who to contact can save valuable time and prevent small problems from escalating.

Every business should have:

• A clear IT contact or support provider
• Up-to-date emergency contact details
• An agreed response plan for out-of-hours issues

Without a plan in place, even minor issues can quickly turn into major disruptions.

A calm Christmas starts with prepared systems

The festive break should be a time to switch off, not worry about what might be happening to your systems.

By taking these simple steps now, businesses can reduce risk, protect their data and return in the new year with confidence.

A little preparation before Christmas goes a long way toward ensuring a calmer, more secure start to January.
