Ocean Security

Ocean Security is a cybersecurity firm that has developed an agentic email security platform to defend against sophisticated, AI-powered email threats. The company was established in 2024 by co-founders Shay Shwartz (CEO) and Oran Moyal (CTO). Headquartered in New York and Tel Aviv, the startup emerged from stealth in May 2026, having secured a total of $28 million in funding from two rounds. This includes an $8 million seed round in 2024 and a $20 million Series A round in 2026, led by Lightspeed Venture Partners with participation from Picture Capital, Cerca Partners, and several prominent angel investors from the cybersecurity industry. Ocean's platform is designed to address the limitations of legacy email security tools, which primarily rely on pattern-based detection and struggle to identify AI-generated attacks that mimic legitimate communication. Instead of surface-level filtering, Ocean employs a network of specialized AI agents that investigate every incoming email in real-time. These agents analyze sender intent, conversation context, and other signals to uncover threats like Business Email Compromise (BEC), vendor email compromise, and advanced phishing that are engineered to evade conventional defenses. The platform also automates security operations by triaging phishing reports, managing quarantine releases, and providing real-time guidance to employees. The company serves a range of enterprise clients, including Fortune 500 organizations and companies such as Kayak, Kingston, and Headspace, and reports processing over a billion emails per month.
