API security company Salt Security announced on Thursday that it raised $140 million in Series D funding, led by CapitalG, Alphabet’s independent growth fund. The latest investment brings the valuation of Salt Security to $1.4 billion. All the investors who have backed Salt Security in previous rounds also participated in this raise, including Sequoia Capital, Y Combinator, Tenaya Capital, S Capital VC, Advent International, Alkeon Capital, and DFJ Growth.
