International Vision Regional Focus

About us

We were established in the UK in 2006 and CREST International was formed in 2015 to act as an umbrella organisation for our regions globally. We currently have chapters in the Americas, Asia, Australasia, Europe and the United Kingdom.

Our strategy is aligned to that of nurturing global capability, capacity, consistency and community in cyber security. It is not tied to any country specific agenda, but we support regions and countries to build their own chapters to service the needs of the local market.

Each region has a council of elected member company representatives who oversee the strategy and activities within the region. The chairs of each of these Regional Councils represent their region on the International Council.

The International Council comprises CREST President Rowland Johnson, the chairs of the five Regional Councils, five cyber security discipline representatives plus members of CREST Operating Executive.

CREST International offers central services in support of members, professionals, governments, regulators and other stakeholders as well as our International and Regional Councils. These services include accreditation, certification and examinations, governance, supporting business between members and the buying community, liaison with governments and regulators, marketing and communication support and much else.
