IT Audit for SMEs: What to Check Before Hiring IT Support

Before hiring external IT support, switching provider or investing in new infrastructure, there is a question few companies ask: do we actually know what state our technology is in today? An IT audit is not a luxury or something reserved for large corporations. It is the starting point that prevents poor investment, detects risks before they become emergencies, and enables decisions to be made on real information rather than assumptions.

This article explains which areas to review, what questions to ask in each, and how to interpret the results to know whether you need external support and what kind.

Why most SMEs don't know what state their IT is in

It is not negligence. Technology in a small company tends to grow by accumulation: a server purchased six years ago because "we needed it urgently", an antivirus nobody remembers renewing, a backup that "we think works" but has not been tested in months. Each decision made sense at the time. The problem is that nobody has reviewed the whole picture from a neutral technical perspective.

The typical result: when something fails, it is not an isolated problem — it is a chain of unreviewed decisions that all collapse together. An IT audit prevents exactly that.

The 6 areas covered by a complete IT audit

1. Servers and operating systems

The starting point is knowing what you have and what state it is in. Many SMEs have servers running obsolete versions of Windows Server (2008, 2012) that no longer receive security patches from Microsoft. Running an unsupported system is not just a technical problem — it is a legal risk in environments handling customer or employee data.

What is reviewed: operating system version, patch status, CPU and RAM load, disk space, event logs, active services that should not be running.

2. Backups

This is the area where the most unpleasant surprises appear. 60% of SMEs that believe they have a backup have never verified that backup can actually be restored. Having a backup that does not work is exactly the same as not having one — you only find out when it is too late.

What is reviewed: backup frequency, which data is included, where it is stored (on-site only = fire or theft risk), when the last restore was verified, estimated recovery time after total loss.

3. Network and connectivity

A poorly segmented network is the main entry point for ransomware in SMEs. If all company devices share the same network — computers, printers, cameras, visitor mobiles — a single compromised device can affect the entire infrastructure.

What is reviewed: network segmentation (VLANs), firewall configuration, guest WiFi policy, remote access (VPN or RDP directly exposed), unidentified connected devices.

4. Security and access controls

You do not need a sophisticated attack to compromise a company. In most incidents we handle, the entry vector was a weak password, an ex-employee account still active, or an RDP exposed to the internet without two-factor authentication.

What is reviewed: password policy, use of two-factor authentication on critical accounts, active user accounts vs. current employees, file and shared folder access permissions, history of failed login attempts.

5. Licences and software

Using unlicensed software is not just an ethical problem — it is an audit risk and in many cases a security risk, because pirated software is often distributed with malware included. And on the other side, many companies pay for software licences nobody uses.

What is reviewed: installed software inventory, active licence verification, software without manufacturer support, active subscriptions vs. actual usage.

6. Email and communications

Email remains the main attack vector for SMEs. A domain without correctly configured SPF, DKIM and DMARC records is a domain that anyone can spoof to send fraudulent emails in your company's name.

What is reviewed: email DNS record configuration, anti-spam filters, email retention policy, use of personal accounts for company communications.

How to interpret the results

An audit does not seek perfection — it seeks to identify real risks in order of urgency. Not all problems found require immediate action. The key is to distinguish three categories:

• Critical risk: active exposure that could cause data loss or business downtime. Examples: open RDP without MFA, backup unverified for more than 6 months, operating system without support. Immediate action required.
• Important risk: not urgent today but becomes critical if not planned for. Examples: server more than 5 years old with no replacement plan, expired licences, unsegmented network. Plan within the next 3 months.
• Recommended improvement: optimisations that reduce risk or cost but are not urgent. Examples: consolidating duplicate subscriptions, improving network documentation.

When does it make sense to hire external IT support?

The audit is useful whether you already have an IT provider or not. If you already have support, the results tell you whether that support is being effective. If you do not, the results help you size what level of service you actually need.

In general, it makes sense to outsource IT support when the company has between 5 and 100 employees and the cost of an incident (production stoppage, data loss, ransomware ransom) clearly exceeds the cost of preventive maintenance. For most SMEs, that threshold is reached much sooner than they think.

If you want to know the real state of your company's IT, we can do the diagnosis at no cost and with no commitment. You will have the report and improvement proposal within 72 hours of the first meeting.
