Powering the Future of Cybersecurity with AI


We’re excited to announce that Jericho Security has raised $15 million in Series A funding, a major milestone that accelerates our mission to transform cybersecurity through AI. This round was led by Jasper Lau at Era Fund, a visionary investor who recognizes the urgent need for agentic AI—dynamic, adaptive, and collaborative—at the core of modern cyber defense. We’re also proud to welcome Lux Capital and other strategic investors who share our conviction that cybersecurity must evolve as fast as the threats it combats.

Conversational Phishing. The Fastest-Growing Threat to Businesses - And It’s Getting More Sophisticated.


Cyber threats have evolved. Conversational phishing, deepfakes, and AI-powered social engineering attacks have rendered traditional security measures obsolete. Organizations now require a new kind of defense - one that is intelligent, proactive, and designed for the threats of tomorrow.


At Jericho Security, we recognized early on that generative AI is reshaping the threat landscape, exposing critical gaps in conventional cybersecurity tools.


Phishing is no longer a static, template-based attack. It’s dynamic. It adapts. It targets with precision. And it won’t be stopped by outdated rule sets or legacy security infrastructure. The only viable defense is intelligent, autonomous AI agents that can learn, evolve, and outmaneuver attackers in real time.


That’s why we built Jericho Security - the first agentic AI Conversational Phishing Platform for multi-channel phishing simulation, security education, and real-time defense. Our technology mimics real-world attacks, autonomously responds, and continuously adapts to stay ahead of evolving cyber threats.

Hyper-Personalized AI-Generated Phishing Simulations - No Code Required


At Jericho, we use AI-generated personas to simulate real-world attacks across voice, SMS, and email. These aren’t just scripted messages—they’re dynamic, adaptive, and strikingly lifelike, evolving to mirror the latest threats.
