ISO/IEC 27001 - Information security management

The ISO 27000 family of standards helps organizations keep information assets secure.

Using this family of standards will help your organization manage the security of assets such as financial information, intellectual property, employee details or information entrusted to you by third parties.

ISO/IEC 27001 is the best-known standard in the family providing requirements for an information security management system (ISMS).

What is an ISMS?

An ISMS is a systematic approach to managing sensitive company information so that it remains secure. It includes people, processes and IT systems by applying a risk management process.

It can help small, medium and large businesses in any sector keep information assets secure.

Like other ISO management system standards, certification to ISO/IEC 27001 is possible but not obligatory. Some organizations choose to implement the standard in order to benefit from the best practice it contains while others decide they also want to get certified to reassure customers and clients that its recommendations have been followed. ISO does not perform certification.
