Cybersecurity startup Ocean has raised US$28 million in total funding to strengthen its AI-powered email security platform designed to defend organizations against advanced AI-driven cyberattacks.
The funding round was led by Lightspeed Venture Partners with participation from Picture Capital and Cerca Partners.
Several high-profile angel investors also backed the company, including:
- Assaf Rappaport from Wiz
- Yevgeny Dibrov and Nadir Izrael from Armis
- Dor Knafo, former CEO of Axis Security
Ocean Building AI-Native Email Security Platform
Founded in 2024 by Shay Shwartz and Oran Moyal, Ocean describes itself as the world’s first “Agentic Email Security” platform.
The company’s system uses multiple AI agents to:
Analyze emails in real time
Understand behavioral patterns
Verify message authenticity
Detect hidden cyber threats
Investigate suspicious communication automatically
Unlike traditional email security systems that rely mainly on predefined rules or spam filters, Ocean’s AI-driven platform focuses on understanding intent, context, and behavioral signals.
AI-Powered Cyberattacks Creating New Security Challenges
The rapid rise of generative AI has significantly changed the cybersecurity landscape.
Cybercriminals are increasingly using AI to create:
- Highly convincing phishing emails
- Fake business communication
- AI-generated impersonation attacks
- Deepfake-based scams
- Social engineering campaigns
According to Ocean CEO Shay Shwartz, traditional email security tools are struggling to keep pace with modern AI-enabled threats.
He said:
“The challenge is no longer simply detecting malicious emails, it’s understanding the intent within increasingly realistic communication.”
Shwartz added that AI-generated attacks can now mimic legitimate relationships, projects, and business communication patterns, making them harder to detect through traditional security systems.
Email Security Market Undergoing Major Transformation
Email remains one of the most common attack vectors for businesses globally.
Industry experts believe the growth of AI-generated threats is forcing organizations to rethink legacy cybersecurity infrastructure.
Modern AI-driven attacks can:
✔ Produce flawless language
✔ Mimic internal communication styles
✔ Reference real projects and workflows
✔ Blend naturally into business conversations
This has increased demand for AI-native cybersecurity platforms capable of contextual analysis rather than simple keyword or signature-based detection.
Ocean Uses Multiple AI Agents for Threat Detection
Ocean’s platform uses what the company calls “AI agents” to continuously investigate and analyze communication patterns.
The system is designed to:
- Understand user behavior
- Detect unusual activity
- Verify sender authenticity
- Identify malicious intent
- Automate threat investigation workflows
The company says its technology protects hundreds of thousands of email accounts globally.
Investors See AI as the Future of Cybersecurity
Investors backing Ocean highlighted the growing need for AI-powered security infrastructure.
Mike Fey, co-founder and CEO of Island, said AI has fundamentally changed email security dynamics.
He stated:
“AI broke email security, and it handed attackers an unfair advantage overnight.”
Fey added that AI is uniquely suited to solving email security challenges because it can understand:
Language
Intent
Context
Communication patterns
which are increasingly critical in detecting sophisticated cyber threats.
Cybersecurity Industry Accelerating AI Adoption
The cybersecurity industry is rapidly adopting AI technologies to improve:
- Threat detection
- Incident response
- Fraud prevention
- Behavioral analytics
- Security automation
AI-powered cybersecurity tools are becoming increasingly important as businesses face:
Rising attack sophistication
Remote work vulnerabilities
Expanding digital infrastructure
AI-generated cyber threats
Analysts believe AI-native cybersecurity platforms could become one of the fastest-growing segments within enterprise software over the next decade.
Israel Continues to Lead Global Cybersecurity Innovation
Ocean also reflects the continued strength of Israel’s cybersecurity startup ecosystem.
The country has produced several globally recognized cybersecurity companies including:
- Wiz
- Armis
- Check Point Software Technologies
Israel remains one of the world’s leading hubs for:
Cybersecurity innovation
AI-driven security research
Enterprise security platforms
Conclusion
With AI-powered cyberattacks becoming more advanced and difficult to detect, Ocean is positioning itself as a next-generation email security platform focused on contextual intelligence and automated threat analysis.
By combining multiple AI agents with real-time behavioral analysis, the startup aims to provide organizations with stronger protection against modern phishing attacks, impersonation scams, and AI-generated cyber threats.
As businesses increasingly adopt AI technologies, the cybersecurity industry is also evolving rapidly — shifting from rule-based detection systems toward intelligent, AI-native security infrastructure.
