Article summary: Most small business offices now run a mix of smart devices that were installed for convenience and then largely forgotten. Each one is a network endpoint, and many ship with default credentials and receive firmware updates rarely, if at all. A focused smart device security audit takes less time than most businesses expect and closes gaps that traditional cybersecurity tools cannot see.
The Wi-Fi-connected thermostat in your reception area has been running the same firmware since it was installed three years ago. The IP camera above the back door still uses the manufacturer’s default password. The smart display in your boardroom connects to your main business network and has never been reviewed by anyone on your team.
None of those devices feels like a security problem. That’s what makes them worth auditing.
Managed IT services address servers, endpoints, and cloud accounts, but the smart devices scattered through your office rarely appear on anyone’s radar until something goes wrong.
Why Smart Devices Create a Different Kind of Risk
Smart devices, also called IoT (Internet of Things) devices, share your network but operate differently from the computers and phones your IT tools typically monitor.
They rarely run antivirus software. They do not generate the kinds of activity logs that security platforms look for. And they often have long software lifecycles or none at all if the manufacturer stops issuing updates.
The result is a class of devices that sits permanently connected to your network, accessible from outside your building, and effectively invisible to your standard security monitoring. Attackers know this.
In early 2024, attacks targeting IoT endpoints jumped 107% year-over-year, according to research from Growth Acceleration Partners.
A 2024 industry survey by ONEKEY found that more than half of respondents had already experienced a cyberattack originating from an OT or IoT device. The same report found that just as many organisations suspected these devices were being deliberately targeted as entry points.
Step One: Build an Inventory
Start by walking through your office and listing every device that connects to your network and is not a conventional computer, laptop, server, or mobile phone. The list is usually longer than people expect.
Common smart devices found in small business offices include:
- Network printers and multifunction devices
- IP cameras and video doorbells
- Smart thermostats and HVAC controls
- Wireless access points and network switches
- Smart TVs, displays, and video conferencing systems
- Badge readers and door access controls
- Smart speakers or voice-activated assistants
- Connected coffee machines, vending equipment, or other appliances
For each device, record the make, model, firmware version if accessible, where it connects on your network, and who is responsible for managing it.
That last column is often blank, which is itself a useful finding.
Step Two: Check the Basics
Once you have an inventory, work through each device against a short checklist. Most of the highest-impact fixes are straightforward.
Default credentials
Many smart devices ship with a standard username and password. Attackers maintain databases of these defaults and scan for devices that have never been changed.
For every device on your list, confirm the factory credentials have been replaced with a unique, strong password.
Firmware updates
Firmware is the software that runs inside the device itself. Manufacturers release firmware updates to patch vulnerabilities, but unlike computer operating systems, these updates are rarely automatic.
Check the manufacturer’s support page for each device and compare the current version against what is installed. If a device’s firmware is significantly out of date and the manufacturer no longer issues updates, that is a device worth replacing or isolating.
Network placement
Ideally, smart devices should not sit on the same network segment as your computers and business data.
A VLAN or a dedicated guest Wi-Fi network can isolate IoT traffic from your core systems. This is one of the most effective controls available and aligns well with zero trust network principles.
Unnecessary features
Smart devices often arrive with capabilities enabled that your business does not need. Universal Plug and Play (UPnP), remote access, and microphone or camera features are common examples.
If the device does not need a feature to do its job, disable it. Fewer active capabilities means a smaller target.
Step Three: Assign Ownership and a Review Cycle
A one-time audit helps, but the real value comes from treating this as a recurring practice.
Smart devices change over time. Firmware vulnerabilities get discovered, staff bring new devices onto the network, and some devices reach end-of-support status without anyone noticing.
Assign a named owner for each device category. That person is responsible for checking firmware updates on a quarterly basis and flagging any new device before it gets connected to the network.
The standard for new devices should be clear: change default credentials, check for update availability, and confirm where on the network it will sit.
A good benchmark is a review every six months for established devices and an immediate check for any new addition. Pairing this with your existing cybersecurity practices gives smart devices the same basic discipline you apply to computers and cloud accounts.

Getting visibility is the first step. From there, the fixes are usually straightforward.

Article FAQs
What counts as a smart device for the purpose of a security audit?
Any internet-connected device in your office that is not a conventional computer, laptop, server, or mobile phone. This includes printers, IP cameras, thermostats, smart TVs, video conferencing systems, badge readers, and connected appliances. If it has an IP address and connects to your network, it belongs on the list.
How often should we audit our smart devices?
A full review every six months is a reasonable baseline for most small businesses. You should also check any new device before it connects to your network, and review your list whenever an employee who manages these devices leaves the company. In high-risk environments, you may want to run a review quarterly.
Do we need special tools to audit smart devices?
For most small businesses, a manual walkthrough and a short checklist are sufficient to start. Network scanning tools can help identify devices you may have missed, but the core of the audit can be done without specialized software.
What should we do with a device that is no longer receiving firmware updates from the manufacturer?
A device that has reached end-of-support should either be replaced or isolated. Isolation means placing it on a separate network segment with no access to your core business systems. This limits the damage if the device is ever compromised, but does not eliminate the risk entirely. Replacing end-of-life devices is the stronger option where budget allows.
