When Smart Devices Become a Risk: The Hidden Cyber Threat Inside Your Office

Smart technology has quietly made its way into the workplace. From smart TVs in conference rooms to voice assistants, wireless printers, security cameras, and even personal smart devices brought in by employees, these tools are designed for convenience.

But there’s a growing issue many businesses don’t realize: not all smart devices are built with business-grade security in mind. When these devices connect to your office Wi-Fi, they can introduce cybersecurity risks that extend far beyond the device itself.

What Are “Smart Devices” in the Workplace?

Smart or “Internet of Things” (IoT) devices are everyday tools that connect to the internet or your internal network. In office environments, these commonly include:

• Smart TVs and conference room displays

• Wireless printers and scanners

• Smart thermostats and lighting systems

• Security cameras and door access systems

• Voice assistants (Alexa, Google Home, etc.)

• Personal smart devices employees bring from home

Many of these devices were designed for home use, not for environments that store client data, financial records, or other sensitive business information.

Why Smart Devices Are a Cybersecurity Risk

Unlike laptops or servers, smart devices often lack basic security protections. This makes them attractive entry points for attackers.

Common vulnerabilities include:

• Weak or default passwords that are never changed

• Rare or nonexistent security updates from manufacturers

• Limited monitoring or visibility once connected to the network

• Insecure communication protocols

• No endpoint protection or activity logging

Once compromised, a single device can allow an attacker to move laterally through the network, access shared systems, or monitor internal activity without being detected.

How Hackers Use Smart Devices as a Back Door

Cybercriminals don’t always target core systems first. Instead, they look for the easiest way in. A compromised smart device can be used to:

• Spy on internal network traffic

• Capture login credentials

• Launch ransomware or malware attacks

• Create persistent access that goes unnoticed

• Use your network to attack other organizations

Because these devices often operate quietly in the background, breaches can remain undetected for long periods of time.

The Risk Is Higher in Regulated Industries

For law firms, CPA firms, healthcare providers, and financial organizations, the risks are even greater.

A compromised smart device can contribute to:

• Data breaches involving client or customer information

• Compliance violations related to cybersecurity regulations

• Cyber insurance claim denials due to weak controls

• Long-term reputational damage

In many cases, businesses don’t even realize a device is connected to their network until after an incident occurs.

How Businesses Can Reduce Smart Device Risk

The good news is that these risks can be managed with the right approach.

Best practices include:

• Segregating smart devices onto a separate network

• Limiting which devices are allowed to connect to business Wi-Fi

• Disabling unused features such as microphones or remote access

• Keeping firmware updated whenever possible

• Monitoring network traffic for unusual behavior

• Conducting regular cybersecurity and vulnerability assessments

Most importantly, businesses should clearly understand what devices are on their network and why.

Why Visibility Matters More Than Ever

You can’t protect what you can’t see. Many organizations are surprised by the number of devices connected to their network once a proper assessment is performed. Smart devices often go unnoticed because they don’t behave like traditional computers — until something goes wrong. A proactive cybersecurity strategy helps uncover these hidden risks before they turn into costly incidents.

Taking a Proactive Approach

Smart technology isn’t going away, and convenience will always be a priority in modern workplaces. The key is ensuring that innovation doesn’t come at the expense of security.

Understanding how smart devices interact with your network — and addressing the risks they introduce — is an essential part of protecting your business, your clients, and your reputation.

If you’re unsure what devices are connected to your network, how they’re segmented, or whether they introduce unnecessary risk, a Cyber Readiness Assessment can help bring clarity.
