Tanium has reached a valuation of $5bn (£3.7bn) after securing $175m from existing investor TPG, according to reports.
Reuters claims that TPG has made its third investment in the end-point security vendor, buying the stock of early Tanium employees.
Neither Tanium nor TPG have confirmed the investment. Sources also told Reuters that the vendor is considering an IPO.
Tanium offers a platform that is designed to connect all of the end-points within an organisation, and improve network visibility and management.
Last year EMEA channel boss John Taylor told CRN that the firm had restructured its management team to make itself more channel friendly.
The vendor also said that it would use a previous funding round, announced in June, to bolster its UK channel.
This latest round of investment (which is still unconfirmed) would take Tanium's total funding to $580.7m, according to Crunchbase.
If Tanium was to go public with its mooted $5bn valuation it would be the largest of recent cybersecurity IPOs.
Carbon Black currently has a valuation of $1.56bn after listing on the NASDAQ market last month, while Avast recently listed on the London Stock Exchange with a market cap of $3.23bn.
Automation firms UiPath and Automation Anywhere close out their funding rounds with $265m and $300m respectively
