Cantina, an AI-driven cybersecurity company specializing in offensive security and vulnerability management, announced new funding led by Framework Ventures, bringing total funding to $16.5 million. The company also introduced Clarion, an agentic security platform designed to automate security workflows from threat discovery to verified remediation, alongside a new brand identity.
From Detection to Resolution
Built on Cantina’s existing AI security engine, Apex, Clarion extends security operations beyond vulnerability detection. The platform uses AI agents to investigate alerts, prioritize risks, coordinate remediation, validate fixes, and automate repetitive security tasks across applications, infrastructure, and operations. The goal is to reduce the growing backlog of security work while allowing teams to focus on critical decisions.
Expanding AI Security Operations
Cantina developed Clarion after observing that many organizations struggled to remediate known vulnerabilities despite identifying them early. The platform enables organizations to deploy AI agents that understand security environments, automate investigations, reduce false positives, create pull requests, verify fixes, and escalate issues requiring human approval.
Supporting Future Growth
The new funding will accelerate development of Clarion, expand the Apex platform and bug bounty services, and grow Cantina’s engineering and research teams. The company believes autonomous AI agents will become a core part of enterprise security operations, helping organizations respond faster to evolving cyber threats while improving operational efficiency.
