Cantina has raised $16.5 million in total funding and launched Clarion, a platform designed to streamline vulnerability remediation workflows for cybersecurity teams. The round marks the company’s official market debut after operating in stealth mode.

The company pivoted its original mission from identifying security flaws to closing the gap between vulnerability detection and resolution. Cantina noted that security teams already possess the tools to identify breaches but lack the bandwidth to triage and fix them. The company currently works with hundreds of customers across healthcare, financial technology, and the artificial intelligence sector.
