There is no straightforward answer to this question as it depends on the size and complexity of your organisation, what systems and processes are already in place and what resources are available.
However, in URM’s experience it typically takes between 6 and 9 months for a small, low complexity organisation to fully implement ISO 27001.
With larger, more complex environments, 9 to 18 months is closer to the norm for fully establishing an ISMS. This naturally assumes that the appropriate resources are made available to achieve the desired outcomes.
