Abnormal Security is a pioneering cybersecurity company that leverages artificial intelligence (AI) and behavioral data science to protect organizations from the most sophisticated email-borne attacks. Their platform focuses on stopping socially-engineered and targeted threats like business email compromise (BEC), vendor email compromise (VEC), account takeovers, and credential phishing. By analyzing identity, behavior, and content, Abnormal Security provides a cloud-native solution that integrates seamlessly with platforms like Microsoft 365 and Google Workspace to detect anomalies and prevent attacks that traditional security solutions often miss.
The San Francisco headquarters serves as the primary hub for executive leadership, research and development, core engineering, product management, marketing, sales operations, and corporate functions.
Located in a prominent downtown San Francisco building, the office likely features modern design elements, collaborative workspaces, and amenities conducive to a high-tech work environment. Specific architectural details are proprietary.
The work culture at Abnormal Security's HQ is characterized by innovation, collaboration, and a fast-paced environment typical of a high-growth technology startup. There's a strong emphasis on solving complex cybersecurity challenges and a customer-first approach.
Its location in San Francisco provides strategic advantages, including access to a rich talent pool from leading universities and tech companies, proximity to venture capital, and a vibrant ecosystem for partnerships and industry events.
Abnormal Security supports a global customer base with dedicated teams and operations across North America, Europe, the Middle East, Africa (EMEA), and the Asia-Pacific (APAC) region. While key physical offices are established in strategic locations like San Francisco, London, Singapore, and Plano, their cloud-native platform architecture allows them to deliver their AI-powered security solutions to organizations worldwide. They also leverage a distributed workforce model to ensure comprehensive global coverage for sales, customer support, and threat intelligence.
