Tanium, the security company that claims to quickly and constantly scan every device on a network, reportedly has captured another $175 million in investment from private firm TPG Growth. The new funding marks TPG Growth's third round of investment in Tanium and raises Tanium's current valuation to roughly $5 billion.

The security firm, founded in 2007, has been on investors' radar screens since its early days. Due to the deep visibility nature of its technology, Tanium counts many large US banks, retail companies, and government agencies among its customers.

In previous statements regarding its finances, Tanium has said that it is profitable, is seeing 100% annual growth, and has substantial cash and liquid reserves. This latest round of investment is rumored to be in anticipation of a long-considered IPO, though the company has not commented on any plans for such an offering.
