About Zygma

Viewing a website can only convey so much about how we can help you and your business. We encourage you to contact us so we can show you the Zygma Difference.


Zygma was founded in 1993 in the UK by its CEO, Richard G. WILSHER.

In 2003 Zygma began operations in the United States and was formally registered in the State of California in 2005, as the Zygma partnership LLC and incorporated in 2018.

Zygma quickly became established as a business specialising in the develoment of Trust (Assurance) Frameworks, Certification and Accreditation schema and identity management processes and standards, in addition to delivering its information security management consultancy services.

The name ‘Zygma’ and our logo are a play on the name of the Greek character ‘Σ’ (Sigma), which is used as a mathematical symbol to indicate ‘the sum of’.  Zygma operates under an ethos of working alongside you, its clients, more with you than simply for you, thereby delivering to you information security which is greater than the sum of our parts.  Hence the deeper meaning of the name.

Zygma’s primary purpose is to deliver a range of information security and identity management audit and consultancy services specifically responsive to its clients’ needs. While easily said, that goal is backed-up by the testimonies of our clients and partners.

Zygma’s tailored consultancy services include ISO/IEC 27001, assurance frameworks (e.g. Kantara’s Identity Assurance Framework, tScheme), PKI deployment and other information security domains.
