Kiteworks captures $456M at a $1B+ valuation to help secure sensitive data

**Kiteworks** (formerly Accellion) raised $456M from Insight Partners and Sixth Street Growth at a valuation over $1B to accelerate acquisitions, hiring, R&D, and business development; the company reports profitability, 100M end users, and 3,650+ enterprise/government customers. Positioned at the “data layer,” it focuses on securing sensitive data across file sharing, transfer, and email via its Private Content Network (PCN) and claims FedRAMP authorization, aligning with rising third‑party risk and regulatory demands; the piece notes a historic 2021 breach tied to legacy services for context.
