Aegis AI, the pioneer in autonomous agentic email security, today announced that it has been selected by LangChain— the world’s leading platform trusted by millions for building the future of AI agents— as its official email security partner.

This partnership represents something we believe is a glimpse into the future: two AI-native companies, built from the ground up on agentic architectures, working together. LangChain enables developers to build intelligent agents that reason, plan, and act. Aegis AI deploys autonomous agents that detect, analyze, and neutralize threats before they reach employees.

This partnership marks a milestone in the "AI-Native" era: LangChain, the framework trusted by millions to build reasoning agents, is now secured by Aegis AI’s network of autonomous security agents.

Why This Matters

Email remains the most exploited attack vector in cybersecurity, with over 90% of successful breaches starting with a phishing email. As AI lowers the barrier for sophisticated, personalized phishing attacks, traditional "rule-based" security has become obsolete.

LangChain recognized that defending against AI-powered threats requires an AI-powered defense. Legacy email security tools rely on signatures and rules written after attacks happen. Aegis AI's network of autonomous agents reason in real time, adapting to threats as they evolve.

"LangChain is at the forefront of the agent revolution. Their choice to partner with us reflects a shared conviction: the future of enterprise security isn't just automated—it’s agentic."

— Cy Khormaee, CEO, AegisAI

What LangChain Gains

• Zero-Day Reasoning: Catching novel attacks by analyzing intent and context rather than just "known bad" links.
• Operational Autonomy: Eliminating rule-tuning and alert fatigue, allowing LangChain’s security team to focus on innovation.
• Real-Time Adaptation: Security that evolves as fast as the LLMs powering the threats.

In Their Words

"Email security has been a cat-and-mouse game for decades, and the old playbook doesn't work against AI-generated attacks. With the rise of AI, we've seen a dramatic increase in the volume, sophistication, and precision of email-based attacks, enabling adversaries to tailor messages at scale and evade traditional detection techniques. What impressed us about Aegis AI is that their agents actually adapt in real time—no rule-writing, no tuning, no chasing false positives. We deployed in minutes and saw threats we'd been missing effortlessly with the agent's reasoning for each email, no black box. It's security that finally keeps pace with the attackers."

Two AI-Native Companies, One Shared Vision

Aegis AI is an AI-native security company founded by former Google engineers. By deploying autonomous agents that detect, analyze, and neutralize threats, Aegis AI protects organizations from the next generation of sophisticated, AI-driven cyber attacks.

LangChain is the premier framework for developing applications powered by language models. Its suite of tools enables developers to create agents that can reason, use tools, and accomplish complex tasks, powering the global shift toward agentic AI.

We couldn't be more excited to protect the team that's empowering the next generation of AI.
