Tim Mather is a partner in the Silicon Valley practice of Fortium Partners. He brings more than 20 years of technology leadership experience as a chief information security officer, a position often hailed as one of the most powerful positions within modern organizations due to its responsibility for information security. Mather has built the information security function from scratch for global brands, often navigating the political and technical environments of an organization to achieve no serious security breaches and protection of intellectual property, despite very large volumes of malicious traffic and sophisticated attacks.

Mather has co-authored two successful books, Cloud Security and Privacy and The Executive Guide to Information Security, both of which are available on Amazon. He holds three master’s degrees: the first in international policy studies from Middlebury Institute, the second in national security studies from Georgetown University and the third in information security from Brandeis University.
