Certified SIM3 Auditors

Authoritative List

Certified SIM3 Auditors have been formally trained in the SIM3 model and its applications. They have been trained by Open CSIRT Foundation (OCF) or authorised partners of OCF (currently only NCA in Japan), and certified by OCF. All Auditors in good standing are listed below, and this is the only authoritative list.

Note that only Certified SIM3 Auditors have the right to perform a formal SIM3 Audit based on the OCF standard – anyone claiming to do so who is not listed below, is making a false claim. If you seek more information about a specific auditor, country or region in regard SIM3, you are welcome to contact us via the contact page.
