Small businesses are relying on IoT more than ever, but security gaps, bandwidth constraints, and spotty internet can put operations at risk. Explore the top IoT network security risks and see how stronger internet can safeguard your business.
The Growing Role of IoT for Small Businesses
If a device can connect to the internet and communicate without needing a human to trigger every action, it’s considered part of the Internet of Things—and IoT adoption is surging. The number of connected IoT devices was projected to climb to 21.1 billion in 2025, a 14% increase from 2024, according to IoT Analytics.
IoT devices range from simple sensors to advanced smart systems. They’re designed to make everyday tasks more efficient, automated, and data-driven. Think video doorbells, smart thermostats, and fitness trackers. Unfortunately, these devices are not secure out of the box.
Small businesses are turning to IoT to handle security, customer checkout, manage energy controls, streamline inventory, and more. Here are just a few ways IoT helps small businesses:
- Improves efficiency: Automating tasks and reducing manual labor.
- Boosts bottom line: Reducing downtime, cutting energy costs, and improving monitoring.
- Enhances security: Detecting issues early to prevent data breaches and malfunctions.
- Elevates the customer experience: Providing faster service and real-time audience insights.
Four IoT Network Security Concerns
Small businesses depend on both device and network performance. To get the most out of IoT, you need fast, dependable business internet. Strong fiber connectivity improves performance and keeps devices running smoothly. With the right internet partner, you can reduce exposure to these common IoT security risks:
1. Poor Network Segmentation
If all your devices share the same network, you’re opening the door to potential problems. Many IoT devices have fewer built-in protections, so if one gets hacked, attackers may be able to reach more important areas of your business—such as your point-of-sale system or customer data—via the network.
Segmenting IoT devices onto their own network helps block attackers from moving around freely. Even if a single device is compromised, your most important systems stay protected.
2. Internet Reliability
IoT devices need a stable, high-speed connection to work properly. When your internet slows down or goes out, your devices can’t do their jobs. Internet reliability directly impacts IoT uptime, especially for security and monitoring devices. If your smart security cameras lose connection, they can’t record or upload footage, leaving your property vulnerable until your internet is restored.
3. Underestimating Bandwidth Requirements
IoT devices are always on and use a lot of data, draining internet bandwidth. A single IoT device may not be an issue, but dozens working at once, like cameras, sensors, scanners, thermostats, and smart lighting, can easily strain your business’s network. Fiber internet supports seamless scalability as your IoT demands grow.
Insufficient bandwidth can cause latency, delays, and interruptions. There’s also a risk of missing critical security updates, which can compromise security and make it easier for hackers to access your systems.
4. Weak or Outdated Device Security
Many IoT devices use default passwords and aren’t updated regularly. Hackers often target these weaker points to access your network. A reliable network paired with secure device setup helps reduce these risks.
IoT Security Solutions for Small Businesses
Ensuring your small business is protected from IoT security risks isn’t as tricky as it may seem. Making a few simple changes can make a big difference.
- Create an inventory of your smart devices to identify outdated devices and verify if they’re properly secured.
- Establish secure, unique passwords for your devices as an extra layer of defense against hackers.
- Stay on top of technology updates, so you can quickly apply fixes for security vulnerabilities.
- Enable encryption on your router to protect your data.
- Turn to business fiber internet for fast connections and high bandwidth.
