Ocean, a startup developing artificial intelligence-powered email security solutions, has raised $28 million in funding led by Lightspeed Venture Partners. The company describes its platform as an "agentic email security" system designed to combat AI-powered phishing attacks.

The funding comes as cybersecurity threats increasingly leverage artificial intelligence capabilities, creating new challenges for traditional email security systems. Ocean's technology aims to address these evolving threats through AI-powered detection and response mechanisms.

The company's founder previously worked as a researcher on Israel's Iron Dome defense system and has a background in cybersecurity research. This technical expertise has informed the development of Ocean's email security platform.

Lightspeed Venture Partners led the funding round, though additional investor details were not disclosed. The investment reflects continued venture capital interest in cybersecurity solutions, particularly those addressing AI-related security challenges.

The funding will support Ocean's continued development of its email security platform and expansion of its operations. The company joins a growing number of startups focused on AI-powered cybersecurity solutions as organizations seek to defend against increasingly sophisticated digital threats.
