Security continues to remain top of mind for organizations and consumers, as each day seems to bring another high-profile network breach. One of the faster-growing startups in the space is capitalising on that by raising some significant funding to fuel its growth. Tanium today said that it has raised another $200 million in funding with a post-money valuation of $6.5 billion. The funding was led by Wellington Management, with Baillie Gifford & Company and Adage Capital Management LP also participating.
