Tanium Inc., a startup that provides cybersecurity software to over half the Fortune 100, today announced that it has raised $200 million in fresh funding at a hefty $6.5 billion valuation.

The round was led by Wellington Management Co., a major investment firm that manages over $1 trillion in assets. It was joined by fellow Wall Street heavyweights Baillie Gifford & Co. and Adage Capital Management LP. Their investment comes only months after Tanium landed a $175 million round that valued it at $5 billion.

The Emeryville, California-based company sells a platform that acts as a centralized hub for managing network protection operations. The software aggregates data from across an organization’s infrastructure, including both backend systems and employee devices, to create a continuously updated picture of its security posture. An extensive collection of modules enables administrators to put this information to use in various ways.

Tanium’s feature set covers just about every major task involved in defending a corporate network. Administrators can use the platform to find vulnerable systems, set up security rules to reduce the attack surface, track down malware infections and take action to close any breach they happen to come across. The platform’s capabilities also extend to certain other areas such as software license management.

This one-stop-shop value proposition is a big part of the reason Tanium has gained so much traction among large organizations. Target Corp., Barclays PLC and the U.S. Air Force are among the hundreds of customers that the startup said use its platform.

The company claims to have seen annual recurring revenue rise by 80 percent in 2017 to $230 million while total billings reached $270 million. And unlike most startups that are expanding so aggressively, it has positive cash flow. The company’s ability to balance growth with the bottom line is no doubt one of the factors that led investors to give it such a steep valuation.

Tanium has raised more than $780 million to date, making it one of the most well-funded startups in the entire cybersecurity industry.
