ISMS qualification

In March 2005 we acquired "ISMS Ver2.0" which is the predecessor of "ISO / IEC27001", the international standard for information security management system and ahead of the competition. At that time interest in this industry was thin. (Migrated to ISO/IEC27001:2005 in September 2006 and to ISO/IEC27001:2013 in August 2015) Nine years passed since the acquisition and our management system is progressing maturation.
