Ocean Security is an email security company founded by Shay Shwartz and Oran Moyal, former Palo Alto Networks Unit 42 researchers who previously served in elite IDF Intelligence Corps and joint IDF/Shin Bet units. Headquartered in New York and Tel Aviv, Ocean builds Email Security Agents, AI agents that investigate the intent of every message in real time rather than relying on static signatures or reputation lists, to catch AI-driven phishing and social-engineering attacks that bypass traditional gateways. It protects organizations ranging from Fortune 500 enterprises to companies like Kayak, Kingston, and Headspace. Ocean raised an $8M seed in 2024 and emerged from stealth in May 2026 with a $20M Series A led by Lightspeed Venture Partners (with Picture Capital, Cerca Partners, and angels including Wiz CEO Assaf Rappaport), bringing total funding to $28M.
