10 Innovative IoT Security Startups That You Should Know

By Maya Heins Published on Sep. 24, 2019

The Internet of Things has grown rapidly since its inception. By 2020, around 30 billion devices are expected to take part in the Internet of Things, with 46% of all internet connections lacking human operators, or functioning through machine-to-machine interactions. In fact, future cities rely almost entirely on the Internet of Things (find out more about IoT and Smart Cities.)

While this industry has tons of potential (some estimate that by 2025 the economic impact of the IoT could be between $3.9-$11.1 trillion worldwide),  concerns about IoT security risks pose an enormous challenge for the industry (we already talked about cybersecurity trends to keep attackers at bay, but that's a different thing). 

When IoT devices lack adequate security systems, they can give malicious hackers access to organizations, resulting in devastating data breaches and/or attacks against companies. “One of the major challenges for IoT security is the fact that security has not traditionally been considered in product design and manufacturing for connected appliances and objects.” By incorporating security-by-design principles, as well as integrating a variety of innovative solutions offered by startups, the IoT industry is trying to address the security concerns of its customers in order to reach its full potential. 

Below is our list of top 10 IoT security startups to keep an eye on!
