Ocean Emerges From Stealth With $28M to Fight AI-Powered Email Attacks
Ocean, a New York- and Tel Aviv-based cybersecurity startup, has emerged from stealth mode with $28 million in total funding to build an AI-native email security platform. The round was led by Lightspeed Venture Partners, with backing from prominent cybersecurity founders who see agentic security as the next evolutionary step in enterprise protection.
The company was founded by Shay Shwartz, a former teen hacker who later served as a researcher for Israel's Iron Dome defense system. Ocean's platform takes an agentic approach to email security, using AI to thoroughly analyze the context of every incoming email to detect fraud and impersonation attempts that traditional rule-based systems miss.
The timing is critical. As generative AI tools become more accessible, attackers are using them to craft highly convincing phishing emails, deepfake voice messages, and impersonation campaigns at scale. Legacy email security tools built on static rules and signature databases are struggling to keep up with these AI-powered threats.
Ocean is already replacing legacy email security tools in enterprise environments, according to the company. The startup's approach — using autonomous AI agents that can reason about email context in real-time — represents a broader shift in the security industry toward agentic architectures that can adapt to novel attack patterns without human intervention.
Ocean's launch signals the rise of 'agentic security' — AI agents that autonomously detect and respond to threats. With AI-powered phishing outpacing traditional defenses, the market for context-aware email security is entering a generational shift.
What makes Ocean different from traditional email security?
Ocean uses AI agents that analyze the full context of incoming emails — not just signatures or rules — to detect AI-generated phishing, deep impersonation, and fraud that legacy systems miss.
