We identified early cybersecurity companies with momentum. All the startups on this list obtained funding in 2016.

Proactive defense and predicting future threats are the new areas being emphasized in the cybersecurity industry. Companies in the space are increasingly using machine learning to thwart attacks early or before they emerge, and mitigate damage when it occurs.

Startups are also offering solutions that range from digital defense training for employees, containerization of cloud network elements for continuous monitoring and quarantining during an attack, real-time analytics on the performance of industrial internet networks, and more.

Despite increased attention on cybersecurity — in light of high-profile recent attacks, including the compromise of millions of Yahoo accounts and government email breaches — a leveling-off of investors’ appetite for cybersecurity this year signals that funding for these companies could be more selective than in recent years past.

With this in mind, we identified 21 early-stage cybersecurity startups to watch. To select them we used our Mosaic algorithm, which tracks the health of private companies. Mosaic has three components, which gauge a company’s health in terms of financing, industry category, as well as overall momentum (the latter component includes jobs data, social and media mentions, web traffic, and more).

We noted several themes among the companies we selected, including:

  • Predictive threat intelligence
  • Real-time network monitoring
  • Modern-day virtual containers and/or cloud data security
  • Employee-targeted cyber defense measures

The companies on our list all leverage one or more of these themes. They are all early-stage startups (Seed/Angel or Series A) and have raised funding this year. Scroll down to see the full list.
