Is there a legal requirement to comply with or be certified to ISO 27001?

There is, generally, no direct legal requirement as such.  Organisations choose whether or not to implement the requirements of ISO 27001 based upon the benefits that would be gained by doing so.  

However, you should pay close attention to any contractual obligations you may have for protecting the information of clients and other stakeholders.  

There is an increasing trend where customers require third party suppliers to implement or certify to ISO 27001, thus making it a legal requirement, by way of a contract.

Our partnership with URM has been outstanding. From supporting us with our own Cyber Essentials certification to assisting our customers with Cyber Essentials, ISO 27001, and virtual CISO services, URM consistently delivers exceptional service. Their expertise, open communication, and ability to allocate the right expert resources for specific requirements makes every project seamless. We highly value their support and look forward to continuing our collaboration.
