Get expert help →Practical note
The 2022 revision reorganised Annex A into 93 controls; organisations certified to the 2013 version needed to transition within the set window.
Choosing a certification body
Choose a body accredited by an IAF member such as NABCB, since unaccredited certificates are often rejected in tenders.
Frequently asked questions
Does ISO 27001 help with DPDP Act compliance?
It supports security safeguards expected under India's Digital Personal Data Protection Act, but privacy obligations need separate measures.
Is SOC 2 the same as ISO 27001?
No. SOC 2 is an attestation report common in the US; ISO 27001 is an international certification.
How long does ISO 27001 certification take?
Smaller organisations often complete it in one to three months; complex or multi-site organisations take longer.
Can it be combined with other ISO standards?
Yes. Integrated management systems combining ISO 9001, 14001, 45001 and others share common structure and audits.
