Currently led by CEO Barry Mainz, Forescout was acquired by private equity firms Advent International and Crosspoint Capital Partners in an all-cash transaction valued at $1.9 billion, closing in July 2020, which transitioned the company from publicly traded (NASDAQ: FSCT) to privately held. Recent activities include expanding its leadership team in April 2024, launching a significant global partner tour in April 2026, and achieving FedRAMP High Authorization in March 2026. The company also continues to publish research on cybersecurity risks, such as a May 2026 report on exposed RDP and VNC servers, and there are reports from early 2026 indicating plans to potentially return to public markets.
