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.

We have been using the services provided by URM for a couple of years now. They have been excellent in providing their expertise on ISO 27001 and SOC 2, which was instrumental in guiding us on our compliance and certification journey. Thanks to their professionalism and knowledge, we continue to obtain certifications smoothly and with confidence.
