This website reflects current ISO27k standards, and therefore the information is somewhat vague in regards to draft standards and those that will change rapidly in the future. It is not uncommon for the content, scope, and title of standards to change during the long drafting and approval process. After they are published, however, standards tend to remain static for several years, allowing us time to adjust!

Study Periods and New Work Item Proposals for additional standards that have not yet been fully scoped, approved or numbered appear on the other ISO27k standards page.

This website contains a lot of information collected from ISO/IEC and similar official sources. Several comments by the owner of the website are included – totally informal, often biased and cynical, bordering on jaundiced. Please note that this website is not an ISO/IEC official body. We have no formal relationship with ISO/IEC. Our best efforts are made to present the picture here; however, all information (in terms of completeness or accuracy) cannot be guaranteed to be fully accurate. For “official” information, contact ISO, IEC or your own national standards body (e.g. ANSI, BSI, SNZ), preferably a member of ISO/IEC JTC 1/SC 27 “Information security, cybersecurity and privacy protection”.

Please monitor the official ISO 27k standards list for the most current, official status of the site as we sometimes fall behind with updates.
