More than 90% of successful cyberattacks start with a phishing email, according to CISA, and AI has changed what those emails look like. Attackers now learn the baselines, relationships, and tone of a business, so attacks look completely normal and slip past tools that were architecturally designed to hunt for patterns and anomalies. Ocean was built for that reality.

Ocean’s agentic platform investigates every email, including those from known and trusted senders. Proprietary AI models screen each message at machine speed, a swarm of purpose-built agents examines anything that warrants a closer look, and Ray, Ocean’s central intelligence engine, delivers the deepest analysis of communication intent, sender relationship history, and sending infrastructure. Every verdict comes with a human-readable report of what was found and why, so security teams get evidence they can trust instead of a score they have to go verify. Ocean deploys through API, read-only, with no MX change, and goes live in hours.

Customers include Kayak, Headspace, and Global Fortune 500 organizations across financial services, healthcare, manufacturing, retail, and more. Ocean processes more than one billion emails every month and protects hundreds of thousands of employee mailboxes globally.

Now in its fourth year, the Cyber 60 honors companies across AI security, identity and access, data protection, cloud security, and security operations, with 20 companies in each of three categories (Early Stage, Early Growth, and Growth). Lightspeed evaluated more than 300 cybersecurity startups on annual recurring revenue, current- and prior-year growth, and business operations, and Fortune reviewed and validated the final list.

Ocean is leading that shift in communications security, protecting some of the largest organizations with an agentic solution that responds to new attacks in seconds. We’re proud to see Ocean on this list.”
