Key points
- Cymphony raised $30 million, including a $25 million Series A.
- Sequoia Capital co-led the Series A and made a prior seed investment.
- The funding values Cymphony at over $100 million.
- Cymphony's platform monitors AI agent access to corporate data and systems.
Cymphony Secures Significant Funding
Cymphony, a startup based in New York and Tel Aviv, announced it has secured $30 million in funding. This includes a $25 million Series A round co-led by venture capital firm Sequoia Capital and SMBC Fin Atlas Beyond Fund. This investment values the company at more than $100 million after the funding round. The Series A follows an earlier, undisclosed seed investment from Sequoia.
Addressing New AI Agent Security Risks
The funding will support Cymphony's efforts to address emerging security risks associated with AI agents in enterprise settings. As AI agents gain access to sensitive corporate data and systems, they operate at machine speed, creating new vulnerabilities that traditional enterprise security systems, designed for human employees, do not adequately cover. AI agents often bypass standard access and identity controls, making it difficult for companies to track their data access.
Cymphony's Workforce Graph Platform
Cymphony's platform aims to bridge this security gap by providing security teams with a single view of employees, AI agents, and other non-human identities, along with their access to systems and sensitive data. The core of its platform is a "workforce graph" that integrates identity, data, and activity signals. This allows for comprehensive monitoring and management of access permissions across the enterprise.
Real-World Risk Identification and Remediation
Cymphony has identified security risks in large companies, such as 85,000 files becoming accessible to AI tools at one U.S. public company, which Cymphony helped to secure. In another instance, an unsanctioned AI tool used an external collaborator's access to scan thousands of sensitive files. Beyond identification, Cymphony uses AI agents to investigate incidents, prioritize security tasks, and automate remediation, including correcting access permissions. The platform can operate automatically, with an option for a managed service for complex cases.

Reporting from
Cymphony, a New York- and Tel Aviv-based startup, raised $30 million in funding, including a $25 million Series A co-led by Sequoia and SMBC Fin Atlas Beyond Fund, to develop security solutions for AI agents in enterprise environments. The funding values the company at over $100 million and will be used to expand its platform, which provides a unified view of human and AI agent access to sensitive data and systems. This development matters because the increasing use of AI agents in enterprises creates new security vulnerabilities, as these agents often access corporate data without the same controls as human employees.
