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.

Our consultant was very thorough and knowledgeable when delivering the ISO 27001 pre-stage-2 internal audit.

I found the course very informative, and the trainer was communicative, supportive and engaging. He is very skilled at adapting to the different types of people and transferring knowledge in a way that sticks with attendees; he delivered the same training over 2 years ago and I still remember the things he taught us. We will definitely be recommending him to other businesses that want to learn about ISO standards. Definitely a great asset to the company.
