It is good to implement ISO 27001 as ISO refers to the International Organization for Standardization. It is an international standard on how to manage information security.

ISO 27001 was developed to help organizations, of any size or any industry, to protect their information in a systematic and cost-effective way, through the adoption of an Information Security Management System (ISMS).

ISO 27001 is the accepted global benchmark for the effective management of information assets. It enables organisations to avoid the costly penalties associated with non-compliance with data protection requirements and the financial losses resulting from data breaches.

ISO 27001 la certification can be done when you have at least four years of experience in process management and Quality management , of which at least two years on a job related to information security.

I want to add some more benefit points which are as follow :

You will Learn Leadership responsibilities.
You will be able to Learn how to perform Internal ISMS audits.
Become Master in ISMS improvement techniques.
You will Control objectives and controls in the organisation.
Perform Audit Planning.
Handle Audit Interviews.

Due to this pandemic there is need an hour to have ISO 27001 certification.
Some organisations don’t even select their IT partners who do not have ISO 27001 implementation in their organizations. When it comes to government’s data related contracts, this becomes a requirement.
The value for ISO 27001 la certification is high in the corporate world.
I have one reference from my colleagues where you can do ISO 27001 lead auditor certification course with training. This course is from GSDC. The ISO 27001 lead auditor certification course is affordable. This certification is valid for lifetime and accepted globally. You can check the given link below :
