THIS IS ABNORMAL
An AI-Native Company Dedicated to Cybersecurity.
Built by AI insiders with an outsider’s perspective: Behavior is the future of cyber defense.
Where We Came From
Founded by AI Insiders and Cyber Outsiders
Beginning in 2010, our founders spent years in adtech — building AI that analyzed massive datasets, learned human behavior, and made anomaly-based decisions in milliseconds.
When they turned to cybersecurity, they saw what its insiders had missed: the AI that models behavior can stop the attacks that exploit it. In 2018, they founded Abnormal to stop crime with AI.
Our Impact
We Protect Millions of People and More Than 25% of the Fortune 500.
Millions of attacks stopped. Thousands of analyst hours saved. Billions in financial losses prevented.
What We Are
AI-Native in Practice, Not Just in Name
We don't just build AI products — we're an AI-native company. Every team at Abnormal, from Product to CS to Finance, runs with AI agents. That operational advantage compounds into faster innovation and better outcomes for our customers.
Who We Are
A Pioneering Team of Humans and AI Agents
Evan Reiser founded Abnormal on a simple belief: AI that understands normal human behavior is a powerful defense against the attacks that exploit it. Today, that belief runs through everything we do — a team of AI and cybersecurity experts, working alongside AI agents, united by a single mission: stopping the attacks that target people. It's a new kind of team, built for a new kind of threat.
What We Believe
The Behavioral AI Enterprises Trust
We move fast because the threat doesn't wait. We own outcomes — for our customers and for each other. We say what's true, even when it's uncomfortable. We measure ourselves by customer results, not internal metrics. And we hold ourselves to a standard the rest of the industry hasn't caught up to yet. That's not a philosophy. That's how we operate every day.
Who We Protect
The Standard for the World's Most Trusted Organizations
More than 25% of the Fortune 500 trust Abnormal with their highly sensitive data and the authority to act on it. That's not a passive relationship. These organizations don't just use Abnormal to flag threats — they give it the access and configure it with the autonomy to make business-critical security decisions on its own. When the world's leading enterprises need security they can trust, they choose Abnormal.
Where We Are Going
The Future of Cybersecurity Looks Nothing Like Today
We're building toward a world that the industry isn't ready for yet. Here's what we know to be true:
The cybercrime AI is about to unleash will dwarf anything the world has seen. Security investment is wildly misaligned with security risk. The industry has normalized failure. We haven't. Customers hold security vendors to unacceptably low standards — and vendors have gotten comfortable with that. AI should do a significant amount, freeing humans for strategy and judgment.
The world needs a new approach to cybersecurity in the AI era. The world needs Abnormal.
