What are connected devices and how to effectively manage them  

Smart speakers that dim your lights on command. Fitness wearables that track your vitals in real time. These are just a few everyday examples of connected devices. These are physical objects that link to a network to exchange data, often automatically. 

Don’t you think that, as enterprises and consumers alike adopt more of these devices, we must learn in-depth about them? Understand how they work, know the benefits and challenges of adopting them, and how to manage them to use them to their full potential.  

So let’s start with the basics and understand what connected devices mean, 

What are connected devices: Definition 

Connected devices are physical objects that can connect to a network, usually the internet, and exchange data with other systems or devices. In simple terms, they’re everyday tools and machines that have gained the ability to “talk” digitally, thanks to built-in connectivity technologies like Wi-Fi, Bluetooth, or cellular networks.

The term “connected devices” is a catchall for a wide range of hardware, beyond traditional servers and desktop PCs, that are increasingly being added to business and home networks. These include everything from smartphones and smartwatches to industrial sensors and smart thermostats.

Understanding more about connected devices

Many of these internet-connected devices are part of the Internet of Things. IoT is a broader concept where once-static physical objects gain the power to communicate, collect data, and sometimes act on that data in real time.

In tech terms, devices that can’t connect or communicate digitally are often called “dumb” devices. For instance, a regular light bulb is a dumb device. But connect it to Wi-Fi and let it be controlled via a mobile app, and it becomes a smart bulb. This transformation from disconnected to connected is what the IoT ecosystem is all about.

So, what makes these devices “smart”? They can perform multiple functions beyond their original purpose, like gathering insights, responding to user commands, or integrating with other systems. While all smart devices are connected devices, not all connected devices are smart. Some may simply transmit or receive basic data without any advanced processing or intelligence.

Ultimately, connected devices are the foundation of modern digital infrastructure. These devices bring automation, real-time communication, and new efficiencies across industries. They are now a core part of modern life and help businesses enable new services and make everyday tasks more convenient.

Is there a difference between smart and connected devices?

Smart vs. Connected devices: Quick comparison

Yes, there is a difference. Although the two terms are often used interchangeably, they describe different levels of functionality.

A smart device is any device with the built-in capability to connect to other devices or networks and perform tasks autonomously. This connection can happen via Bluetooth, Wi-Fi, NFC, or other network protocols. Smart devices usually come with an operating system, computing power, and the ability to run applications. Examples include smartphones, smartwatches, tablets, or smart locks.

Connected devices, on the other hand, may not have advanced computing capabilities. Their core function is to connect to a network and send or receive data, often performing simple, predefined actions. Think of sensors, RFID tags, or GPS trackers.

In simpler terms: All smart devices are connected devices, but not all connected devices are smart devices.

But why does this distinction matter? It matters because understanding the difference is essential for IT teams when implementing policies, setting access controls, and defining management strategies based on device complexity and functionality.

How connected devices work: Components and principles

Whether it’s a smart thermostat at home or a sensor in a factory, connected devices operate based on a few core principles. Despite the variety in form and function, most internet of things connected devices follow a similar architecture:

1. Physical interaction with the real world

At the heart of any connected device is a physical component. This component detects, measures, or influences the physical environment. This could be a temperature sensor, motion detector, camera, or actuator.

2. Built-in processing and connectivity

Connected devices typically have a small CPU or microcontroller onboard. These chips handle basic computing tasks and are often built on open-source platforms like Arduino or Raspberry Pi. A network adapter (Wi-Fi, Bluetooth, Zigbee, or cellular) allows the device to transmit and receive data.

3. Reliable network access

For these devices to stay connected and functional, they must access a network, which is usually a private or enterprise Wi-Fi network, but sometimes cellular or mesh networks, depending on the use case. Without network access, their “connected” status becomes meaningless.

4. Software or cloud interface

A companion application, cloud platform, or centralized management system is often needed to monitor, control, or configure the device. This software layer is where users define rules, get alerts, view data, or initiate remote actions.

5. Secure communication and data transfer

Although not always visible, encryption, authentication protocols, and compliance mechanisms are critical components to ensure data is securely transmitted and that the device isn’t vulnerable to unauthorized access.

Together, these components form the backbone of how connected devices work. They bridge the physical and digital worlds to automate actions, enhance visibility, and support smarter operations.

Components of connected device communication

• IoT device: The physical hardware (like a sensor or smart appliance) that collects data or performs actions based on commands.
• Local communications: Short-range communication protocols such as Bluetooth, Zigbee, or Wi-Fi that enable the device to talk to nearby systems.
• Gateways: Intermediary devices that translate local communication protocols into internet-friendly formats and securely forward data to the cloud.
• Network or cloud servers: Centralized platforms that receive, process, and store data from connected devices, often powering analytics, automation, and remote control.
• User interface: Applications or dashboards (mobile, desktop, or web) that let users monitor, control, or configure connected devices remotely.

How to mitigate the challenges of using connected devices

Using connected devices effectively means having the right strategies to tackle their challenges. Here are proven ways IT teams can stay ahead:

1. Using a Unified Endpoint Management (UEM)

UEM solutions give IT teams centralized control over all endpoints, including IoT and connected devices. This unified approach simplifies device monitoring, security enforcement, and updates, thus reducing management complexity and improving overall security posture.

2. Network segmentation and zero-trust access

By segmenting networks and applying zero-trust principles, organizations limit device access strictly by type or function. This reduces the risk of unauthorized access and helps contain potential breaches within isolated network zones.

3. IoT device lifecycle management

Properly managing devices from onboarding to deprovisioning ensures that every connected device is authenticated, configured securely, and removed when no longer in use. This practice prevents “forgotten” devices from becoming security gaps.

4. Security policies and patch automation

Automating security policy enforcement and timely patching of device firmware and software closes vulnerabilities before they can be exploited. This proactive approach keeps devices secure without manual overhead.

5. Data encryption and secure connectivity protocols

Encrypting data both at rest and in transit ensures that information collected or shared by connected devices remains confidential and tamper-proof. Using secure protocols protects communications from interception and attacks.
