ISO 27001 is an international standard that defines an Information Security Management System which, being auditable, is a test of an organisation’s controls. Information Security Management Systems (especially those based on recognised standards such as ISO 27001, COBIT, ITIL, etc.) are the foundation for sustainable security. The flexibility and proactive capability built into an ISO 27001 compliant ISMS allow an organisation to react to new challenges in an effective, formal manner. A full reassessment is required every 3 years, and surveillance audits which review a section of the ISMS are performed every 6 months. Customers may contact our auditors (Certification Europe) to verify the validity of the LON3 and LON1 data centre certification, which can also be viewed on the Certification Europe website by following the link below.
