Best Antivirus for IoT Devices: What to Know & What to Use

Why Are IoT Devices So Easy to Hack?

Most IoT devices are designed for ease, not defense. That’s the problem.

Here are a few common reasons they’re vulnerable:

• Weak or default passwords: Many devices ship with generic logins like “admin/admin” or “123456.” If users don’t change them, hackers can walk right in
• Lack of firmware updates: Unlike smartphones or PCs, smart appliances often don’t get regular security patches, leaving old bugs wide open
• No built-in antivirus or firewall: Most IoT devices don’t have the processing power for antivirus software. That leaves them exposed unless your router or external system offers protection
• Always connected, always on: Devices like smart speakers and cameras stay online 24/7, making them easy targets for scanning and exploitation

In short, they’re small, simple, and underprotected, which makes them the perfect backdoor into your home network.

What Kind of Attacks Target IoT Devices?

1. Botnets

Hackers can hijack your smart devices and turn them into part of a “botnet”—a network of infected devices used to launch massive cyberattacks or spam campaigns. You probably won’t notice…until your smart lightbulb starts participating in a DDoS attack.

2. Eavesdropping and spying

That cute little baby monitor or home assistant might double as a bug if it’s compromised. Hackers can listen in or even access video feeds remotely.

3. Credential theft

Some malware targets login credentials or Wi-Fi information. Once they have access, cybercriminals can jump from device to device or into your more sensitive tech.

4. Ransomware

Yes, ransomware for smart devices is real. Imagine having to pay a hacker to get your smart thermostat working again.

Do I Need a Specific Antivirus for IoT?

While traditional antivirus software is great for phones, laptops, and desktops, it’s not designed to run on devices like smart plugs or connected doorbells. Instead, IoT antivirus protection usually works in one of two ways:

Router-level protection: Security software is installed on your Wi-Fi router or gateway to monitor all traffic passing through your network. This lets it protect every connected device, even ones that can’t run antivirus software directly.

Network-level monitoring: Some antivirus tools offer centralized control panels to manage your IoT security remotely, with AI-driven alerts and automated defenses.

The key is protecting the whole ecosystem, not just individual devices.

What to Look for in an IoT Antivirus 

Not all security software is built with smart devices in mind. When choosing antivirus or security tools for IoT environments, focusing on network-level features and non-invasive protection is important. Here’s a deeper dive into the features that actually matter:

• Device discovery and mapping: A good IoT antivirus solution should automatically scan your network and identify all connected devices, including ones that don’t show up on your standard router interface. This feature often comes with a dashboard that labels each device (like “Living Room TV” or “Smart Fridge”) so you know exactly what’s on your network. Some tools even flag unknown or unauthorized devices that try to connect, which is key for detecting intruders
• Real-time threat detection: Since many IoT devices can’t run antivirus directly, the security software needs to monitor traffic between your devices and the internet. Look for solutions that use deep packet inspection and behavioral analysis to catch unusual activity, like a light bulb suddenly trying to communicate with a foreign IP address. Real-time detection helps prevent botnet participation, data leaks, and other threats before they spread
• Firmware vulnerability alerts: Many smart devices don’t auto-update, or worse, stop receiving updates altogether. Top-tier antivirus tools can detect when a device is running outdated firmware and notify you of known vulnerabilities associated with it. This feature is essential for maintaining long-term security without manually checking every product’s update history
• Device behavior monitoring: IoT-specific antivirus solutions often include AI or machine learning capabilities to establish behavioral “norms” for each device. If your smart speaker suddenly spikes in data usage or your thermostat tries to access strange servers, the system will flag it, even if it’s a new or unknown type of threat. This zero-day detection is critical in the IoT space, where signatures alone aren’t enough
• Encrypted traffic inspection: Many modern threats are hidden in encrypted (HTTPS) traffic. Some IoT antivirus tools can safely inspect this encrypted data without compromising your privacy or device performance. This ensures that malicious scripts or remote control attempts can be caught, even if they’re wrapped in secure channels
• Intrusion prevention system (IPS): IPS features go a step further than detection, they actively block malicious traffic or commands in real time. This includes stopping brute-force login attempts on your smart lock, blocking DNS hijacking, or preventing your IoT camera from contacting known malware servers. An IPS is a major defense line that works invisibly in the background
• Mobile app control and alerts: Your security solution should come with a mobile companion app that gives you visibility and control over your home network anytime, anywhere. Ideally, it allows you to pause access for specific devices, receive security alerts in real time, and approve or deny new device connections from your phone
• Support for multiple device types: A modern IoT antivirus tool should support a wide range of devices, not just computers and phones. That includes smart TVs, thermostats, voice assistants (like Alexa or Google Home), smart lights, doorbells, baby monitors, game consoles, and even connected kitchen appliances. The more flexible the platform, the more complete your protection

Extra Tips to Lock Down Your IoT Devices

Even with antivirus software, your habits matter. Here are a few extra ways to stay secure:

• Change default passwords (every time!)
• Disable remote access if you don’t use it
• Update firmware regularly on your devices
• Use two-factor authentication where possible
• Segment your network (create a separate Wi-Fi network just for IoT)

And if your device no longer receives updates? It might be time to replace it.

Conclusion

IoT devices work wonders, but are also dangerous without proper protection. Every device you add is another entry point for hackers, from smart bulbs to connected ovens. While traditional antivirus programs won’t cut it, the right tools—especially those with router-level security—can give you peace of mind.
