I am looking for a data security standard for our company to improve customer satisfaction. please help me to clear differences between ITIL V4 and ISO 27001 Standard.which one is the best for Information Security in my company.
If you are looking for Information Security implementation only, than ISO 27001 would be better fit. But, if you plan to implement/improve other aspects (organization, functions, processes, management of the services) than ITIL is better. ITIL will give you opportunity to manage various standards and best practices, like ISO 27001, Agile, DevOps, etc.
