The Internet of Things (IoT) has transformed how we interact with technology—from smart thermostats that optimize energy use to industrial sensors streamlining manufacturing. By 2025, experts predict there will be over 75 billion IoT devices globally. But with this explosion of connectivity comes a surge in cybersecurity threats. Hackers are increasingly targeting IoT devices to steal data, hijack networks, or launch large-scale attacks.
At Pantheon Global IT, we specialize in securing IoT ecosystems for businesses and individuals. In this guide, we’ll uncover the most pressing IoT security risks, share actionable solutions, and explore how emerging technologies are reshaping the future of connected device safety.
Why IoT Security Matters More Than Ever
IoT devices are gateways to your network. A single vulnerable smart camera or sensor can expose your entire system to cybercriminals. Consider these sobering stats:
- 57% of IoT devices are vulnerable to medium- or high-severity attacks (Source: Palo Alto Networks).
- 98% of IoT traffic is unencrypted, risking data leaks (Source: Zscaler).
For businesses, a breach can mean financial loss, reputational damage, or regulatory fines. For consumers, it could lead to identity theft or compromised home security. Let’s break down the risks and how to address them.
Top 5 IoT Security Risks in 2025
1. Weak or Default Passwords
Many IoT devices ship with generic passwords like “admin” or “12345.” Users often neglect to change them, creating easy entry points for hackers. For example, in 2023, a botnet attack hijacked 100,000 IoT devices using default credentials to launch DDoS attacks.
Solution:
- Replace default passwords with 12+ character phrases combining letters, numbers, and symbols.
- Use a password manager to store unique credentials for each device.
2. Outdated Software & Firmware
IoT devices often lack automatic update features. Outdated firmware leaves vulnerabilities unpatched—like the Ripple20 exploit, which affected millions of IoT devices due to unpatched TCP/IP software.
Solution:
- Enable automatic updates where possible.
- Schedule quarterly firmware checks for critical devices.
3. Lack of Encryption
Many IoT devices transmit data in plain text. Hackers can intercept unencrypted traffic from smart locks, medical devices, or industrial sensors to steal sensitive information.
Solution:
- Enable SSL/TLS encryption for data transmission.
- Use VPNs for remote IoT device management.
4. Insecure Network Connections
Public Wi-Fi or poorly secured home networks expose IoT devices to man-in-the-middle attacks. For instance, hackers can spoof a smart thermostat’s connection to manipulate settings.
Solution:
- Isolate IoT devices on a dedicated guest network.
- Use WPA3 encryption for Wi-Fi routers.
5. Poor Physical Security
IoT devices in public or remote locations (e.g., security cameras, weather sensors) are vulnerable to physical tampering. Attackers can extract data or install malicious hardware.
Solution:
- Use tamper-proof casings and disable USB ports.
- Implement geofencing to alert unauthorized device access.
Step-by-Step Guide to Securing IoT Devices
For Businesses

✅ Need enterprise-grade IoT security? Schedule a consultation.
For Consumers
- Research Before Buying
Choose devices with Matter-certified or UL Cybersecurity Certified labels. - Secure Your Router
Change default router credentials and disable UPnP (Universal Plug and Play). - Disable Unused Features
Turn off remote access or cloud storage for devices that don’t need it.
Emerging Technologies Shaping IoT Security
1. AI-Powered Threat Detection
AI algorithms analyze device behavior to flag anomalies. For example, Microsoft’s Azure IoT Edge uses AI to detect unusual data patterns in real time.
2. Blockchain for Data Integrity
Blockchain creates immutable logs of device interactions. Startups like Xage Security use blockchain to secure industrial IoT deployments.
3. Secure Hardware Chips
Embedded Secure Element (eSE) chips, like those in Google Nest devices, store encryption keys offline to prevent remote extraction.
