An Abnormal security company that enterprises trust

“As part of our strategy to move our organization to the cloud, we prioritized investing in a comprehensive approach to security. We identified socially-engineered email attacks as our number one security risk, which requires a solution that understands individual employees’ identity, relationships and content, in context. We selected Abnormal Security based on the innovative way it uses data science married with behavioral and predictive analytics to prevent attacks before they happen.”
Dr. Alissa Abdullah aka “Dr. Jay” Former Chief Information Security Officer at Xerox
