Ocean

Ocean is an agentic email security company headquartered in New York City and Tel Aviv, founded in 2024 by Shay Shwartz and Oran Moyal. Both served in elite Israeli military intelligence units and later led offensive social engineering operations, and they built Ocean to defend email from the attacker's point of view. The company emerged from stealth in May 2026 with twenty eight million dollars in total funding, an eight million dollar seed led by Picture Capital followed by a Series A led by Lightspeed Venture Partners, with Cerca Partners and a roster of security angels including Wiz chief executive Assaf Rappaport and the founders of Armis. Its thesis is that generative AI has made flawless, context rich spear phishing cheap to produce at scale, which breaks detection tools built to flag anomalies.

Rather than scoring messages against static rules or anomaly models, Ocean deploys a network of AI agents that investigate every inbound email the way a human analyst would. The core engine, called Ray, examines sender identity, message content, embedded links, technical infrastructure, and the recipient's business context to judge intent. It cross references claimed identities against multiple data sources and can even reach out to a supposed sender through a separate channel to verify legitimacy. When a message is judged malicious the agents act directly, quarantining it or alerting the user with a plain language explanation. Ocean runs on a purpose built small language model tuned for fast email analysis rather than a general purpose model, and connects to Google Workspace and Microsoft 365 through the API in minutes, adding retrospective analysis of prior mail.

Ocean positions itself as a full replacement for legacy and first generation tools rather than an add on, and reports real scale, more than one billion emails scanned in its first year and a similar volume every month, protecting hundreds of thousands of mailboxes for customers such as Kayak, Kingston Technology, and Headspace. For an enterprise, especially in finance or digital services, that is losing ground to AI generated impersonation and wants autonomous investigation instead of rule tuning, Ocean is a strong fit. A buyer wanting a broad, multi channel security platform, open model choice, or self hosted deployment will find Ocean deliberately narrow, deep on email and light everywhere else.
