Surf, a New York-based cybersecurity startup, has emerged from stealth with $57 million in funding to build AI-driven security agents capable of autonomously identifying and fixing enterprise vulnerabilities. The round was led by Accel, with participation from Cyberstarts and Boldstart Ventures.
Founded in 2024 by Yair Grindlinger along with a team of cybersecurity veterans, Surf is focused on transforming how enterprises manage security operations. The company’s platform leverages “agentic AI” — autonomous systems that continuously monitor environments, detect risks, and remediate issues without human intervention.
Surf’s approach addresses a growing challenge for enterprises: managing increasingly complex IT environments amid persistent cyber threats. Its AI agents are designed to identify misconfigurations, dormant accounts, and exposed sensitive data — vulnerabilities often exploited by attackers — and resolve them in real time.
By shifting from reactive incident response to proactive, continuous security hygiene, Surf aims to reduce the operational burden on security teams while improving overall resilience. The platform operates around the clock, ensuring that potential threats are mitigated before they escalate into breaches.
The newly raised capital will be used to advance product development, expand the company’s workforce, and support broader enterprise adoption. Surf’s launch comes amid a surge in investor interest in AI-powered cybersecurity solutions, particularly those leveraging automation to enhance efficiency and threat prevention.
With strong backing and a clear focus on autonomous security operations, Surf is positioning itself at the forefront of the next wave of innovation in enterprise cybersecurity.
