Been asked about ISO 27001 in a tender or client questionnaire?
You’re not alone. Many businesses first encounter ISO 27001 when clients or prospects ask about their information security credentials during the procurement process.
Why Clients Ask About ISO 27001
When you handle their business data, customer information, or personal details, clients want assurance that you’ll protect it properly. ISO 27001 certification demonstrates you have robust information security controls in place – it’s their way of managing risk when sharing sensitive information with contractors and suppliers.
What is ISO 27001?
ISO 27001 is the international standard for information security management systems. Think of it as a framework that helps you systematically protect all the information in your business – from customer data and financial records to employee details and business plans.

What Does ISO 27001 Actually Involve?
ISO 27001 isn’t just about IT security or installing antivirus software. It’s a comprehensive Information Security Management System frequently shortened to ISMS when talking about ISO 27001. The information security management system covers the areas in the business that affect security and includes:
Risk Assessment – Identifying what information you have, where it’s stored, and what could go wrong and then putting in place mitigation to reduce the impact should the risk become active.
Policies and Procedures – Documented processes for handling information securely across your entire business.
Physical Security – Protecting offices, servers, and paperwork from unauthorised access.
Staff Training – Ensuring everyone understands their role in keeping information secure and how to handle threats to the confidentiality, integrity and availability of information.
Access Controls – Managing who can access what information, both digitally and physically.
Supplier Management – A process for due diligence and contract management with suppliers.
Incident Management – Having plans in place for when things go wrong.
Business Continuity – Having a process in place to manage a major incident or technical failure and keep the business running.
Regular Reviews – Ongoing monitoring and improvement of your security measures.
