Axis Security, a leader in Zero Trust Network Access (ZTNA), announced a $50 million Series C round, bringing its total raised to date to $100 million.

The funding round was led by new investor Spark Capital with participation from existing investors Canaan Partners, Ten Eleven Ventures, and Cyberstarts.

The firm's Axis Application Access Cloud provides a flexible platform for zero trust network access. Application isolation technology keeps users separate from the network, and the application, greatly reducing the threat surface.
