IoT Analytics counts 21.1 billion connected devices in 2025, and the security baseline underneath that growth is grim: Palo Alto Networks measured 98% of IoT device traffic as unencrypted and found 57% of devices vulnerable to medium- or high-severity attack. Unlike laptops, these devices rarely get patched — Unit 42 found 83% running unpatched operating systems — so a vulnerable device usually stays vulnerable for its whole service life.
Parks Associates captures the consumer half of the problem: half of smart home owners worry about device security but take no action. With the market headed toward $5.55 trillion by 2034, the device count will keep outrunning the fixes. The practical move is architectural, not per-gadget — put IoT devices on a separate network segment, change default credentials, and run encryption at the router so unencrypted device traffic never leaves home readable.
Why This Data Matters
The cybersecurity landscape evolves rapidly. Each year brings new attack vectors, regulatory changes, and shifting threat patterns. By tracking these statistics, organizations and individuals can allocate security resources more effectively and anticipate emerging risks before they escalate.
Industry reports from organizations like the National Institute of Standards and Technology (NIST), CISA, and the Electronic Frontier Foundation (EFF) consistently highlight the growing sophistication of cyber threats and the critical importance of proactive defense measures.
How to Protect Yourself
The most effective step you can take today is using a VPN to encrypt your internet connection and hide your online activity from ISPs, advertisers, and potential attackers. Combined with strong passwords, two-factor authentication, and regular software updates, a VPN forms a critical layer of your personal security stack.
Google's Safety Center recommends encrypting your connection on public networks — exactly what GhostShield VPN provides with ChaCha20 encryption and no-logs policy.
