Best alternatives to Ocean Security in 2026
Old-school email security tools mostly check a sender's reputation or scan for known-bad links, which modern AI-written phishing emails are specifically designed to slip past — a scam email impersonating your CEO asking for a wire transfer often has no attachment or link to flag at all. Ocean investigates every email more deeply, using AI to understand what the email is actually asking for and whether that request makes sense in context, catching impersonation and business-email-compromise attempts that look completely normal on the surface. Ocean Security is an agentic AI email security platform built around purpose-built investigation agents that analyze intent, enrich context, and autonomously triage the security team's queue — including quarantine management, campaign remediation, and real-time in-inbox guidance for employees. It's pitched directly against legacy secure email gateways (SEGs) as catching the social-engineering and BEC attacks that surface-level scanning misses, with a stated goal of reducing false positives. The company (which raised a $28M round led by Lightspeed) sells to enterprise security leaders and CISOs on a demo/sales basis; no self-serve pricing is published.
