For many businesses, an IT audit only becomes a priority when something has already gone wrong.
A cyber insurance renewal lands with difficult questions. A client asks for proof of security controls. A compliance requirement appears during a tender. Or worse, a security incident exposes gaps that should have been found earlier.
The reality is simple: every business relies on technology, and every business should be able to prove that its IT is secure, controlled, documented and fit for purpose.
So, if someone asked to audit your IT today, would your company be ready?
What Is an IT Audit?
An IT audit is a structured review of your technology, security, systems, processes and documentation. It looks at whether your IT environment is properly managed, secure, resilient and aligned with the needs of your business.
A good IT audit does not just look at the hardware and software you use. It should also review how those systems are configured, who has access to them, how data is protected, how risks are managed, and whether the business can recover quickly if something goes wrong.
For small and medium-sized businesses, an IT audit can be one of the most valuable ways to uncover hidden risks before they become serious problems.
Why IT Audits Matter More Than Ever
Technology is no longer just a support function. It sits at the heart of most businesses.
Email, cloud storage, accounting systems, customer records, remote working, phones, Wi-Fi, security cameras, payment systems and business applications all depend on reliable IT.
At the same time, businesses are facing more pressure from cyber insurance providers, clients, suppliers, GDPR and data protection requirements, Cyber Essentials, industry-specific compliance, remote working risks, increasing cyber threats, cloud security misconfigurations, ageing hardware and unsupported software.
An IT audit helps you understand where you are now, what needs attention, and what should be improved over time.
What Would an IT Audit Look At?
A proper IT audit should cover the key areas that affect security, reliability and business continuity.
User Accounts and Access Control
One of the first areas to review is who has access to your systems.
This includes checking whether leavers have been removed, whether admin accounts are used correctly, whether users have more access than they need, and whether shared accounts are still in use.
Common issues include old user accounts still active, weak or reused passwords, too many users with administrator rights, no formal joiner, mover and leaver process, no regular access reviews and lack of multi-factor authentication.
Access control is one of the most important areas of IT security. If user accounts are not managed properly, the risk of data loss, unauthorised access and cyber attack increases significantly.
Multi-Factor Authentication
Multi-factor authentication, often known as MFA, is now a basic security requirement.
If your business uses Microsoft 365, cloud applications, remote access systems or online finance platforms, MFA should be enabled wherever possible.
An IT audit should check whether MFA is enabled for all users, whether admin accounts are protected separately, whether any accounts are excluded from MFA, whether legacy authentication methods are disabled and whether conditional access policies are in place.
MFA is one of the simplest and most effective ways to reduce the risk of account compromise.
Devices and Patch Management
Every laptop, desktop, server, phone and tablet connected to your business represents a potential security risk.
An audit should review whether devices are supported, updated and managed correctly.
Key questions include whether all devices are running supported operating systems, whether Windows updates are being installed promptly, whether third-party applications are being updated, whether devices are encrypted, whether lost or stolen devices are protected, whether personal devices are accessing company data and whether devices are centrally managed through tools such as Microsoft Intune.
Unsupported operating systems and unpatched software are common routes into a business network. They are also areas often reviewed during Cyber Essentials assessments and cyber insurance checks.
Microsoft 365 and Cloud Security
Many businesses now rely heavily on Microsoft 365, SharePoint, OneDrive, Teams and Exchange Online.
These platforms are powerful, but they need to be configured properly.
An IT audit should review Microsoft 365 security settings, email security and anti-phishing controls, SharePoint and OneDrive permissions, external sharing settings, conditional access policies, admin roles, mail forwarding rules, data retention, backup arrangements and Secure Score improvements.
Cloud services are not automatically secure just because they are hosted by a major provider. Your business is still responsible for configuration, access control and data protection.
Backups and Disaster Recovery
Backups are often assumed to be working until the day they are needed.
An audit should not simply ask whether backups exist. It should check whether they are complete, secure, tested and suitable for the business.
Important questions include what systems are backed up, how often backups are taken, where backups are stored, whether backups are protected from ransomware, whether Microsoft 365 emails and files are backed up separately, when the last successful restore test took place and how quickly the business could recover.
A backup is only useful if it can be restored when required. Regular testing is essential.
Cyber Security Protection
Cyber security should be reviewed across users, devices, email, cloud platforms and the network.
An IT audit should look at endpoint protection, email filtering, phishing protection, web filtering, security monitoring, dark web monitoring, user awareness training, incident response plans, firewall configuration and remote access security.
It should also review whether the business has a clear process for dealing with suspicious emails, compromised accounts, malware alerts or data breaches.
Good cyber security is not just about tools. It is about people, process and technology working together.
Network and Wi-Fi Security
Your network connects everything together, so it should not be overlooked.
An audit should review firewall security, Wi-Fi configuration, guest Wi-Fi separation, network segmentation, switch management, VPN access, open ports, remote access controls and network documentation.
Many businesses still operate flat networks where everything sits on the same subnet. This can increase risk because one compromised device may be able to reach other systems too easily.
Separating business devices, guest Wi-Fi, servers, printers, CCTV and management systems can significantly improve security and reliability.
IT Documentation
Good documentation is often the difference between controlled IT and reactive IT.
An audit should check whether the business has accurate records for hardware assets, software licences, cloud subscriptions, user accounts, network diagrams, firewall rules, backup schedules, vendor contracts, support agreements, password and credential management, and key business systems.
Without documentation, businesses become too dependent on individual knowledge. That creates risk when staff leave, suppliers change or urgent issues occur.
Policies and Procedures
IT audits should also review whether your business has suitable policies in place.
These may include an IT acceptable use policy, password policy, remote working policy, Bring Your Own Device policy, cyber security policy, data protection policy, backup policy, incident response plan, business continuity plan and joiner, mover and leaver process.
Policies do not need to be overcomplicated, but they do need to be clear, practical and followed.
Common IT Audit Failures
Many businesses are surprised by what an audit uncovers.
Some of the most common issues include former employees still having active accounts, MFA not enabled for all users, admin accounts used for daily work, old laptops running unsupported software, no central device management, Microsoft 365 sharing settings being too open, no tested backup restore process, poor password practices, no cyber security training, guest Wi-Fi connected to the main business network, firewall rules that have not been reviewed for years, no clear IT asset register and no documented recovery plan.
Most of these issues are fixable. The key is finding them before they become a business risk.
The Benefits of Being Audit Ready
Being ready for an IT audit is not just about passing a checklist. It gives your business better control, stronger security and greater confidence.
An audit-ready business is more likely to reduce cyber risk, improve cyber insurance readiness, meet client and supplier requirements, support Cyber Essentials certification, improve business continuity, reduce downtime, protect sensitive data, control user access more effectively, make better IT investment decisions and plan future improvements with confidence.
It also helps senior management understand where the business stands and what needs to be prioritised.

Would You Be Ready?
An IT audit should not be something to fear. It should be seen as an opportunity to improve, strengthen and protect your business.
If your company was audited today, could you confidently answer these questions?
Do we know who has access to our systems?
Are all our devices secure and up to date?
Is MFA enabled everywhere it should be?
Are our backups tested?
Could we recover quickly after a cyber attack or system failure?
Is our Microsoft 365 environment properly secured?
Do we have accurate IT documentation?
Are our policies up to date?
Are we ready for cyber insurance or Cyber Essentials?
If the answer to any of these is “not sure”, now is the right time to review your IT.
