How Long Does It Take To Implement ISO 27001 For Organisations
By Vijay Kumar
The timeline for implementing ISO 27001 for the organisations can vary depending on several factors, such as the size of the organization, the scope of the project, and the availability of resources. However, with proper planning and execution, organisations can typically implement ISO 27001 between 6-8 months. Here’s a breakdown of the timeline and steps involved:
Implementation Process And Plan:
Step 1 – Scope Of Your ISMS (~1 Week)
Define the organizational and system boundaries for the assessment.
Step 2 – Complete An ISO 27001 Gap Assessment(~1-2 Months)
Gap Assessment compare the organization’s existing controls against ISO 27001 control. This helps to identify any control deficiencies or gaps that need to be addressed for compliance. This phase can vary widely in duration, from a few weeks.
Step 3 – Risk Assessment(~1month)
Identifying, assessing, and managing information security risks is central to ISO 27001. This phase involves setting up a risk management framework, which can take several weeks to months, depending on the organization’s complexity.
Step 4 – Implement Information Security Controls(~1-2 Months)
With the ISMS in place, the organization implements and tests security controls, conducts employee training, and integrates security practices into daily operations.
Step 5 – Internal Audit (2 Months)
An internal audit reviews the ISMS to ensure it meets ISO 27001 standards and helps identify any gaps before the external audit.
Step 6 – External Audit(~1 Month)
Conducted by an accredited certification body, the external audit involves a thorough review of the ISMS.
Step 7 – Corrective Actions And Certification(~1 Month)
After the external audit, any non-conformities are
addressed. Once rectified, the organizat,ion receives ISO
27001 certification. This final phase can take few
weeks.
Implementation Cost: depends on Company Size and
Complexity- Larger organizations may incur higher costs
due to the complexity and scope of their operations.
Scope – A broader scope of the ISMS, the more
resources will be required. This includes the number of
departments, processes, and systems covered by the
ISMS.
Resource Availability- Availability of internal
resources versus the need to hire external consultants can
significantly impact costs.
Existing Security Posture- Organizations that
already have robust information security controls in place
may incur lower costs compared to those starting from
scratch
