Investment firms Fidelity Management & Research Company, Baillie Gifford and T. Rowe Price led a $150m funding round in Tanium, a privately held endpoint security and systems management company. "Tanium has pioneered a fundamentally different approach to the management and protection of endpoints by unifying operational visibility, security controls, and risk management. This transformative approach is driven by a fantastic leadership team that we have grown to deeply admire, with a proven track record of category creation and execution at scale. We are pleased to extend our investment in Tanium," James Anderson, Baillie Gifford Partner.
