About the Fortune Cyber 60

Ask any CEO about the biggest risks to their business, and cybersecurity is sure to be near the top of the list.

The chilling worst-case scenarios are in the headlines on any given day: ransomware attacks that shut down hospitals and schools; private customer information stolen by cybercriminals and sold on the dark web; internal company emails grabbed in a data breach and published online.

It’s no wonder that demand for cybersecurity services is booming. Industry research firm IDC estimates that spending on security products and services will total $212 billion this year, and reach $330 billion in 2027. Established tech vendors like Cisco are racing to add security tools to their offerings. In September it announced plans to acquire Splunk for $28 billion, the largest acquisition in its nearly 40-year history.

Fortune teamed up with Lightspeed Venture Partners to identify the fastest-growing startups in this critical field.

The companies in the Fortune Cyber 60 offer a broad range of tools and services, from threat detection and identification management to disaster recovery and compliance with regulations. Some have been around for nearly a decade, while others only recently celebrated their first birthdays, but their products have earned the trust of major customers and investors.
