Agentic email security that investigates every message before threats land.

Ocean is an agentic email security platform built to stop the targeted attacks that conventional email defenses miss. As attackers use AI to craft business email compromise, spear phishing, and social-engineering campaigns engineered to evade anomaly and pattern detection, surface-level tools that scan for known signatures fall short. Ocean addresses this by investigating each email in depth rather than scanning it on the surface, applying the kind of reasoning a skilled analyst would to determine whether a message is a genuine threat.

The platform runs AI agents purpose-built for email security that understand intent, enrich each message with environmental context, and follow the evidence to reach a verdict at machine speed. Beyond detection, Ocean autonomously works the SOC queue, triaging user phishing reports, handling quarantine release requests, and remediating campaigns without human intervention. It also assists employees in real time, acting as an inbox analyst that delivers guidance at the moment of concern and replies to reported emails with the reasoning behind each verdict.

Ocean's distinguishing focus is depth of investigation aimed squarely at agentic business email compromise and the targeted social-engineering attacks, including abuse of trusted domains and legitimate infrastructure, that evade signature-based and SEG tooling. It is built for enterprise security teams and SOCs that need accurate detection without false-positive overload, automated email response that offloads manual triage, and real-time protection for employees who are not security experts. The company recently emerged from stealth with $28M in funding.
