Walk through any modern office and you will find more connected devices than most people realize. Printers that sync with the cloud, VoIP phone systems, smart security cameras, and thermostats that adjust automatically – devices that have become part of the furniture.
But while most companies invest in protecting their laptops, servers, and email systems, the growing network of smart devices operating in the background rarely receives the same attention. Each one connects to your business network, communicates data, and in many cases ships with minimal built-in security. According to Forescout’s 2025 Riskiest Connected Devices report, average device risk has risen 15% year over year, with common network devices like routers now accounting for more than half of all devices carrying critical vulnerabilities.
For cybercriminals, these overlooked devices represent low-hanging fruit: entry points that bypass the defenses you have already put in place. As IoT (Internet of Things) adoption accelerates, IoT security has become one of the most pressing and least addressed gaps in SMB cybersecurity.
What Counts as an IoT Device (and Why Businesses Love Them)
IoT (the Internet of Things) is a broad term, but in practice it refers to any device in your office that connects to the network and exchanges data. That includes networked printers and copiers, VoIP phone systems, smart security cameras, environmental sensors, building access controls, and smart thermostats. Some businesses also run connected conference room displays, smart lighting, and wireless point-of-sale systems.
These devices are popular for good reason. They streamline operations, reduce manual tasks, and give business owners greater visibility into how their facilities run. The problem is not the technology itself, but the fact that most of these devices are adopted without any consideration for smart device security. They are plugged in, connected to the same network as everything else, and mostly forgotten. That gap between adoption and security is exactly where the risk begins, and it’s one of the most commonly overlooked areas of network security for business.
How Insecure IoT Devices Become Entry Points for Hackers
The reason IoT devices are such attractive targets comes down to how they are built and how they are managed – or more accurately, how they are not managed.
The Security Gaps Hiding in Plain Sight
Most smart devices ship with default usernames and passwords that are never changed after installation. Firmware updates, when they are available at all, are rarely applied. Unlike laptops and servers, most IoT devices lack built-in security features like encryption or endpoint protection. And because they are seldom included in routine security audits, they sit on business networks for years without anyone assessing whether they pose a risk.
How Attackers Exploit the Blind Spot
That is all an attacker needs. A single compromised device – be it a smart camera, a networked printer, or even a connected thermostat – can serve as a foothold to move laterally across your network, reaching email systems, financial records, or sensitive client data. One of the most notorious examples involved a casino that was breached through an internet-connected fish tank thermometer, giving attackers a pathway into the broader network.
IoT security gaps are actively exploited because attackers know that most small and medium-sized businesses focus their defenses on traditional endpoints and overlook everything else. When there is no network segmentation, no device inventory, and no monitoring in place, a single unsecured gadget can undermine an entire SMB cybersecurity strategy.
The devices are not the problem; the lack of visibility and oversight is.
Practical Steps to Secure Your IoT Devices
A few foundational measures can significantly reduce your exposure.
- Segment your network: Place IoT devices on a separate network from your core business systems. That way, if a smart camera or printer is compromised, the attacker cannot move directly to your financial data, email servers, or client records. Network segmentation is a straightforward practice that dramatically limits how far a breach can spread – and it’s a cornerstone of smart device security.
- Stay on top of firmware updates: Most IoT manufacturers release firmware updates to patch known vulnerabilities, but these updates are rarely applied automatically. Establish a regular schedule for checking and applying updates across all connected devices, not just your computers and laptops. A device running outdated firmware is an open invitation.
- Change default credentials immediately: Default usernames and passwords are publicly documented for most devices, which means attackers do not need to guess. They just look them up. Every IoT device should be configured with a strong, unique password the moment it’s deployed.
- Know what is on your network: You cannot secure what you cannot see. Conduct a full audit of every connected device in your environment, including those that may have been added informally by staff. Maintaining an up-to-date device inventory gives you the visibility you need to manage IoT security effectively and strengthen network security for business operations across the board.
How Cyber Express Helps Protect Your Entire Network
The steps above are a strong starting point, but most small and medium-sized businesses do not have the time, tools, or in-house expertise to manage IoT security on an ongoing basis. That is where a dedicated IT support partner makes the difference.
Cyber Express provides managed security services designed to protect your entire network, not just the traditional endpoints. That includes device discovery to identify every connected asset, vulnerability assessments to pinpoint where your exposure sits, and continuous monitoring that detects suspicious activity across all devices, including the ones most businesses overlook. We also support proper network segmentation to isolate IoT traffic from critical systems and provide guidance to ensure new devices are onboarded securely from day one.
True SMB cybersecurity is not about protecting laptops and servers alone. It’s about securing the entire ecosystem your business depends on: every printer, every camera, every sensor, and every connection point in between.
