Do VPNs really help secure IoT devices?

[pratiksha05]

The Internet of Things (IoT) has transformed our homes into smart ecosystems where devices like smart TVs, cameras, thermostats, voice assistants, and even refrigerators are interconnected. While these technologies bring convenience, they also open doors to new cybersecurity risks. Every smart device is essentially a small computer connected to your network—and if not properly secured, it can be exploited by cybercriminals.
Securing IoT devices at home is not just about protecting gadgets; it's about safeguarding your privacy, financial data, and family's safety. Below are the best cybersecurity practices for IoT devices that every homeowner should follow in 2025 and beyond.

1. Change Default Passwords Immediately
Most IoT devices come with factory-set usernames and passwords that are publicly available online. Hackers often exploit these defaults to gain quick access. The very first step after installing any IoT device is to set a unique, strong password. Use a combination of uppercase letters, lowercase letters, numbers, and symbols.
💡 Tip: Avoid using easily guessable details like birthdays, phone numbers, or "123456."

2. Enable Two-Factor Authentication (2FA)
If your IoT device or related mobile app supports two-factor authentication, enable it immediately. This adds a second layer of security by requiring a code sent to your phone or email, reducing the chances of unauthorized access even if your password gets compromised.

3. Keep Firmware and Software Updated
Cybercriminals constantly look for vulnerabilities in outdated firmware. Manufacturers often release security patches to fix these weaknesses. Always enable automatic updates when possible, or set a reminder to manually check for updates regularly. An unpatched IoT device is like an open door for hackers.

4. Use a Separate Wi-Fi Network for IoT Devices
One of the smartest practices is to segregate IoT devices on a guest or secondary network. This way, even if an IoT device is compromised, hackers won't have direct access to your primary devices like laptops, smartphones, or work computers.
💡 For example, create a "SmartHome" Wi-Fi network exclusively for IoT devices and keep your main network for personal gadgets.

5. Disable Unnecessary Features
Many IoT devices come with features like remote access, voice controls, or UPnP (Universal Plug and Play) enabled by default. If you don't use them, turn them off. Reducing unnecessary functionalities limits potential entry points for attackers.

6. Install a Strong Firewall and Router Security
Your router is the gateway to all connected devices. Protect it with:
A unique admin password (never keep the default one).


WPA3 encryption (or WPA2 if WPA3 is not available).


Disabling remote access to the router interface.


Some advanced routers even come with built-in IoT security monitoring tools that can detect suspicious activity.

7. Monitor Device Activity Regularly
Keep an eye on your devices using your router dashboard or IoT monitoring apps. Look for unusual behavior like devices connecting at odd hours or to unknown IP addresses. This may indicate a device has been hijacked.

8. Use a VPN for Enhanced Privacy
A Virtual Private Network (VPN) on your router can encrypt all traffic between IoT devices and the internet. This makes it harder for hackers or malicious third parties to intercept and misuse data.

9. Educate Everyone at Home
Cybersecurity is not a one-person job. Family members, especially kids, should understand the risks of IoT devices. Teach them not to click suspicious links, download unverified apps, or share device passwords.

10. Invest in Trusted Brands Only
Not all IoT devices are created equal. Cheap, unknown brands may cut corners on security. Always buy IoT gadgets from reputable manufacturers that provide regular updates and have transparent security policies.

11. Disable Data Collection When Possible
Many smart devices collect and share personal data. Always review privacy settings and disable unnecessary data sharing. Minimizing data exposure reduces risks if the device gets hacked.

12. Perform Regular Security Audits at Home
Set a schedule to check your IoT devices every few months. Look for:
Outdated firmware


Weak passwords


Unused devices still connected
 This proactive approach helps prevent vulnerabilities from going unnoticed.



Why These Practices Matter
Cyberattacks on IoT devices are rising rapidly. From botnet attacks (like Mirai) that turn devices into hacking tools to spyware attacks that misuse cameras and microphones, unsecured IoT ecosystems can lead to serious consequences. By implementing these best practices, you not only protect your gadgets but also strengthen your overall home cybersecurity posture.

Conclusion
IoT devices bring convenience and efficiency, but with great connectivity comes great responsibility. Treat every smart device as a potential risk point and secure it accordingly. By following the practices above—strong passwords, network segmentation, regular updates, and continuous monitoring—you can enjoy the benefits of smart living without compromising your safety.
