Shift5, the OT cybersecurity company that defends military platforms and critical transportation systems from cyberattacks, announced today that it has raised $50 million in a Series B round to protect against increasing cyber-physical threats against planes, trains, and weapon systems. The round was led by New York-based global private equity and venture capital firm Insight Partners. The fundraise highlights Shift5’s exponential growth and momentum, including eight-figure ARR in the first year of product sales, multiple seven-figure deals in 2021, and a 200% increase in employee headcount. Armed with new capital, Shift5 will make significant investments in product development and new talent across all teams to keep pace with demand across transportation and national defense industries.
