Our Vision

Mammoth Cyber’s vision is to help secure every interaction between users, application or infrastructure and ensure that they adhere to principles of zero-trust.

Solving the problem includes securing remote access, granular control over data access, centralizing identity, ensuring least privileged access, and preventing the spread of malware. And doing this in a manner that is agnostic to the applications, platforms, infrastructure, or devices.

Mammoth Cyber was founded by Michael Shieh and Yonghui Cheng. Michael

was co-founder of vArmour and helped blaze the path for various technologies at Juniper, NetScreen and Lucent Technologies. Yonghui was a fellow at Palo Alto Networks and led the development of several new products at Juniper and NetScreen. They have hired a team with decades of experience in security, a broad range of experience in developing innovative product and scaling companies.
