Mammoth Cyber is a cybersecurity company that develops and provides an Enterprise Browser platform designed to secure user interactions with applications, data, and generative AI tools across distributed work environments. The company's core product, the Mammoth Enterprise Browser, is a managed browser environment that gives organizations control over how users access SaaS applications, web apps, and enterprise resources, regardless of the device or location used. The platform is built around zero-trust principles, incorporating features such as granular data access controls, centralized identity management, least-privilege access enforcement, and malware prevention. A notable capability called "Trust Circle" is used to prevent sensitive data leakage, as demonstrated in deployments within the global financial sector. Mammoth Cyber also offers a Mobile Enterprise Browser, extending secure browsing capabilities to mobile devices. Key use cases addressed by the platform include securing BYOD (Bring Your Own Device) workforces, managing third-party contractor access, enabling GenAI security, reducing reliance on Virtual Desktop Infrastructure (VDI), and supporting safe browsing policies. The company serves verticals including healthcare, government, and banking. The company was founded by Michael Shieh and Yonghui Cheng. Shieh previously co-founded vArmour and held roles at Juniper Networks, NetScreen, and Lucent Technologies. Cheng was a fellow at Palo Alto Networks and led product development at Juniper and NetScreen. Mammoth Cyber operates with a partner ecosystem that includes technology vendors, infrastructure providers, and solution delivery partners.
