Industrial cybersecurity startup Nozomi Networks secures $100M in pre-IPO funding

Nozomi Networks, an industry cybersecurity startup that aims to shield critical infrastructure from cyberattacks, has raised $100 million in pre-IPO funding.

The Series D funding round includes investments from a number of equipment, security, service provider and go-to-market companies including Honeywell Ventures, Keysight Technologies and Porsche Digital.

This funding comes at a critical time for the company. Cyberattacks on industrial control systems (ICS) — the devices necessary for the continued running of power plants, water supplies, and other critical infrastructure — increased both in frequency and severity during the pandemic. Look no further than May and June, which saw ransomware attacks target the IT networks of Colonial Pipeline and meat manufacturing giant JBS, forcing the companies to shut down their industrial operations.

Nozomi Networks, which competes with Dragos and Claroty, claims its industrial cybersecurity solution, which works to secure ICS devices by detecting threats before they hit, aims to prevent such attacks from happening. It provides real-time visibility to help organizations manage cyber risk and improve resilience for industrial operations.

The technology currently supports more than a quarter of a million devices in sectors such as critical infrastructure, energy, manufacturing, mining, transportation, and utilities, with Nozomi Networks doubling its customer base in 2020 and seeing a 5,000% increase in the number of devices its solutions monitor.

The company will use its latest investment, which comes less than two years after it secured $30 million in Series C funding, to scale product development efforts as well as its go-to-market approach globally.

Specifically, Nozomi Networks said it plans to grow its sales, marketing, and partner enablement efforts, and upgrade its products to address new challenges in both the OT and IoT visibility and security markets.
