Yes i agree with point there is need of ISO certification .
ISO 27001 is an international standard on how to manage information security. ISO refers to the International Organization for Standardization.
ISO 270001 Certification is needed in this modern era. Training and certification will give an itemized comprehension of review philosophy including meeting methods, inspecting hazard appraisals, guaranteeing fitting restorative activity, and rehearsing new aptitudes.
The value for this certificate is more in the corporate world
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).

Achieving accredited certification to ISO 27001 demonstrates that your company is following information security best practice, backed by an independent, expert assessment of whether your data is adequately protected. ISO 27001 is supported by its code of practice for information security management, ISO/IEC 27002:2013.
