The thermostat on the wall. The reception camera. The boardroom TV that joins meetings. The printer that scans straight to email.
Each one is effectively a small computer, with its own IP address, firmware, and a path onto your network. In many cases, a vendor installed them years ago and haven’t been updated since.
For Canadian businesses thinking about their network and connected devices, this is often where attention drifts. Laptops and servers are patched regularly; smart fridges, conference room cameras, and office printers are not.
Why Office Smart Devices Slip Through the Cracks
Internet of Things (IoT) devices are any piece of equipment, beyond traditional computers, which connect to a network and exchange data.
The Canadian Centre for Cyber Security highlights common examples in business environments, including smart meters, printers, connected appliances, and building systems such as HVAC, electrical, and water controls.
Most devices ship with default passwords, run firmware that rarely gets updated, and sit on the same network as the rest of the business.
Attackers know this.
Verizon’s 2025 Data Breach Investigations Report highlights that while most breaches stem from stolen credentials or phishing, poorly secured connected devices can still provide an entry point in certain environments.
According to JumpCloud’s 2025 IoT trends review, unpatched firmware is responsible for roughly 60% of IoT security breaches, while more than half of IoT devices contain critical vulnerabilities that attackers can exploit.
Small Canadian businesses are attractive targets for attackers. A device no one is monitoring can offer a discreet path into a network containing client records, financial information, and email.
What Belongs in Your Office IoT Audit Checklist
The point of an audit is not perfection, it is visibility. Once you understand what’s on your network and how it is configured, the right fixes become obvious.
Build an inventory of every connected device
Walk through the office and list everything that connects to your network or to Wi-Fi. Include the obvious items and the easy-to-miss ones.
- Printers, scanners, and multifunction devices
- IP cameras and door access systems
- Smart TVs, video bars, and meeting room hardware
- HVAC controllers, thermostats, and building sensors
- Voice assistants, smart speakers, and smart plugs
- Network attached storage and backup appliances
- Any vendor-supplied “smart” appliance in a kitchen, lobby, or workshop
Record the model, location, owner, and IP address for each device. A simple spreadsheet is enough to start.
Change every default credential
Default usernames and passwords are public. Attackers run automated scans to find devices still using them.
The risk is not theoretical.
In Cybernews’ large-scale printer security experiment, researchers were able to send unsolicited print jobs to 56% of 50,000 internet-facing printers, largely because the devices were publicly exposed or poorly secured.
As Cybernews documented, a single weak point, such as an exposed service or default configuration, can allow unauthorised access to thousands of devices. Replace default logins, store passphrases in your business password manager, and enable multi-factor authentication where supported.
Update firmware and disable unused features
Many devices ship with services switched on that you will never use. Telnet, FTP, plug-and-play discovery, and remote management ports are common examples.
Each one expands the attack surface.
Turn off any features or services you do not actively use and keep each device on a regular firmware update schedule. Most modern equipment supports automatic updates, which the Canadian Centre for Cyber Security recommends enabling wherever possible for IoT devices.
Segment IoT devices from your core network
This is the single most useful control on the list.
Put smart devices on a separate network from the one that carries your business applications, email, and file shares. Most business-grade routers support a guest network or VLAN (virtual local area network), and no new hardware is needed.
If a smart camera or printer is compromised, segmentation keeps the attacker from reaching the systems that matter most.
Build a Repeatable Review Cadence
An audit is only effective if you repeat it regularly.
Set a calendar reminder every quarter. Re-check your inventory for new devices, confirm firmware is current, and review who has admin access.
The Get Cyber Safe toolkit for small and medium businesses suggests treating IoT security as a shared responsibility between leadership, IT, and the staff who interact with the devices.
A short one-page policy works better than a long document nobody reads. Note who owns each device class, how often it is reviewed, and what happens when something new is added. The same visibility principle pays off in a passwordless rollout for your team or a cleanup of unsanctioned browser extensions.
Ready to Tighten Up Your Connected Devices?
An office IoT audit can be completed in a few hours and provides a clear view of what’s on your network, what’s configured properly, and what needs attention. The fixes are typically small, but the reduction in risk is significant.
If you are not sure where to start, or your inventory has grown faster than your team can track, Data First Solutions can help. We work with Toronto and GTA businesses to review connected device security, set up segmentation, and build a quarterly cadence.

Article FAQs
What counts as a smart device in an office?
Any equipment beyond traditional computers that connects to your network or to Wi-Fi. That includes printers, IP cameras, smart TVs, thermostats, building controllers, voice assistants, and connected appliances.
How often should we run an office IoT audit checklist?
Quarterly works for most small businesses. Run a fuller review once a year and add any new device to the inventory the day it is installed.
Do we really need a separate network for smart devices?
Yes, where possible. Network segmentation limits how far an attacker can move if one device is compromised. Most business-grade routers support it without new hardware.
Is the risk overstated for a small Canadian business?
No. The Canadian Centre for Cyber Security documents IoT compromises in organisations of every size, and small businesses are often targeted because their devices are easier to reach.
What is the first thing to fix if I only have an hour?
Change every default password on every connected device. That one step closes the most common attack path used against office IoT equipment.
