Securing Identity in the Agentic Era
Cyber is the biggest threat to business in an AI-first world. We're building autonomous systems that protect companies as they grow more complex every day, and we're starting with access.
If attackers move at AI speed, defense has to move faster.
Cybercrime is one of the biggest threats to today's economy. It already does more than $500 billion in damage every year, and it hits real places: banks, hospitals, schools, and your personal data.
AI will make this worse. Attackers will probe, adapt and strike faster than human teams can respond. So defense needs to become autonomous too.
That is why Lumos exists. We are building systems that defend at the same speed they get attacked. Our mission is to prevent breaches and let humans embrace AI and thrive.
Lumos means light.
Lumos began at Stanford, in the Computer Science department, at the dawn of the AI era.
Andrej Safundzic, Alan Flores-López, and Leo Mehr were grad students, working on systems shaped by that shift. At Stanford, they met Peter Levine at Andreessen Horowitz, who recognized identity had become one of the most important layers in enterprise software.
The security problem felt personal. Andrej was co-founder of DigitalService4Germany, the first startup acquired by the German Federal Government, which became the government's Digital Task Force. The work focused on digital infrastructure for 80 million people, with security at the center.
As AI proliferated, the problem became clear. Threats were accelerating and the damage was increasing. Humans and AI agents needed to be protected. Access had become the front door to everything, but teams were drowning in complexity.
That is why we founded Lumos. Lumos means bringing light to the dark. We do the same for access, so you can embrace AI with confidence.
Teams everywhere run on Lumos.
From fast-scaling brands to global enterprises with 100,000+ employees, security and IT teams trust Lumos to govern who can access what.

Identity is the top cyberattack entry point
Our 2026 report found 96% of organizations faced identity-related incidents, with stolen credentials and MFA fatigue as the leading way in, and makes the case for agentic AI inidentity security.
