Vanta, a compliance automation startup, has secured $150 million in a Series D funding round led by Wellington Management. This latest investment values the company at $4.15 billion, a significant increase from its $2.45 billion valuation following a previous $150 million raise in July 2024. Vanta provides tools to help businesses automate and streamline their compliance processes, making it easier to meet security and regulatory requirements. The funding will likely be used to further develop its platform and expand its market reach.
