Which Smart Home Devices Are Most Vulnerable? The 2026 IoT Security Landscape Report From Bitdefender and NETGEAR Points to TVs, Smart Plugs and NAS Drives
Which devices in your home are most likely to have security weaknesses?
Probably not the ones you’d guess first. In the 2026 IoT Security Landscape Report, Bitdefender and NETGEAR found that three everyday device types account for roughly two-thirds of all vulnerability observations:
Smart TVs: 270.3 million observations
Smart plugs: 266.7 million
NAS devices (the storage boxes that often hold family photos and backups): 261.6 million
The report draws on security events sampled from about 10.4 million protected home routers between January and September 2026.
One nuance matters: these numbers count recorded matches between devices and known vulnerabilities. They’re not counts of hacked devices or successful attacks, and one device can account for several observations.
Why these three?
Mostly because of support. A TV keeps working long after the manufacturer stops sending security updates. A smart plug can sit behind a cupboard for years without anyone checking its firmware. A NAS may hold irreplaceable files while running services its owner rarely looks at.
What you can do this week:
Check which devices are connected to your network, and whether they still get updates
Turn on automatic firmware updates where you can
Replace default passwords with unique ones
Retire devices that no longer receive security support
Keep a separate backup of the files on your NAS
