15 Cool IoT Security Startups That Are Keeping Connected Devices Safe

Startups For IoT Security

Security is the big buzzword for the Internet of Things as more devices become connected to networks – and subsequently IoT users grapple with more security vulnerabilities.

While a significant concern for customers, IoT security also presents a huge opportunity for the technology industry. According to market research firm IDC, worldwide IoT security spending will skyrocket to $547.2 million in 2018, up from $348.3 million in 2016.

Dozens of startups are popping up with new security solutions for IoT applications – both on the consumer and enterprise side, but also for new vertical markets such as manufacturing and health care. Following are 15 of the coolest IoT security startups.
