View company profile

At Abnormal Security, we are at the forefront of cybersecurity innovation, pioneering a revolutionary approach to protect the modern enterprise from the most sophisticated and damaging email attacks. Through our groundbreaking, AI-native human behavior security platform, we are fundamentally transforming how organizations defend against threats that exploit human vulnerability. Our core technology leverages advanced machine learning and behavioral data science to create a precise, identity-based understanding of every individual within and outside an organization. This allows us to detect subtle anomalies in communication patterns, relationships, and business processes that signal a potential attack, stopping threats that traditional security solutions miss. We are not just building another security product; we are engineering a new paradigm of defense that is autonomous, adaptive, and capable of anticipating and neutralizing never-before-seen attacks in real-time.

Our commitment to innovation extends beyond our core detection engine. We are building a comprehensive security platform that provides complete protection across the entire cloud email environment. This includes inbound email security to block phishing, malware, and social engineering attacks; robust protection against internal and external account takeovers; and full security operations center (SOC) automation to streamline threat response and reduce manual effort. By integrating seamlessly with major cloud platforms like Microsoft 365 and Google Workspace via a simple API, we provide immediate value without disrupting email flow. The team at Abnormal Security is composed of industry veterans and bright minds from leading technology companies like Google, Twitter, and Amazon, all driven by a shared passion for solving the most critical challenges in cybersecurity. We are dedicated to building a future where organizations can operate securely and confidently in an increasingly complex digital world, empowered by the intelligence and autonomy of our AI-driven platform.
