Thales helps organisations assess, strengthen and maintain ISO 27001-aligned Information Security Management Systems (ISMS) through gap analysis, remediation and expert advisory services.

Why does ISO27001 certification matter to your organisation?

Information security is a high-priority issue for all organisations.

Perform an ISMS internal audit

An ISMS audit reviews objectives, assets, stakeholders, risks and controls, including implementation plans, and checks measurement mechanisms for improvement. ISO 27001 requires defined documents but does not prescribe how the ISMS must be built.
Protect information assets

ISO 27001 certification demonstrates that your organisation has implemented an Information Security Management System (ISMS) to protect information assets and sensitive data, reduce the risk of unauthorised access and strengthen resilience against cyber threats. It enhances trust with customers, suppliers and regulators by providing independent assurance that appropriate security controls are in place. As data protection regulations continue to evolve across countries such as Australia and New Zealand, aligning with or achieving ISO 27001 certification helps organisations improve compliance and reduce the risk of security breaches.
Provide structure to your cybersecurity strategy

ISO 27001 helps bring structure to your cybersecurity strategy by focusing on the risks that matter to your organisation. Instead of reacting to individual threats, it offers a framework for addressing a broad range of risks holistically, ensuring your security approach is consistent, scalable and aligned to business needs.

What is ISO 27001?

ISO 27001 is an internationally recognised and accredited standard for the establishment, operation, maintenance and governance of an Information Security Management System (ISMS). The standard details what an organisation needs to do to select and implement a set of controls that protect information assets. While many organisations will have various controls in place, ISO 27001 provides industry-recognised guidance and structure to assist organisations, mitigate risk and achieve certification as appropriate.

Information security is a high-priority issue for all organisations. Customers, suppliers and other stakeholders are all part of a highly connected ecosystem, making the protection of data a key priority for everyone.

ISO 27001 certification is a strategic lever to enhance credibility, ensure compliance and support long-term business resilience. It provides assurance that you can be trusted to protect information and that you have considered the risks your organisation, and its supply chain faces, and have put into place appropriate mitigation strategies.

Conformity with ISO 27001 international standards

While ISO 27001 specifies that compliant organisations should have an Information Security Management System (ISMS), the standard does not mandate the specific content it should contain. An ISO 27001 ISMS is a set of policies, procedures and controls that address the people, process and technology risks an organisation faces. An ISMS does not specifically focus on tools and technologies but on risks and controls that keep information assets secure. It gives organisations a systematic approach for protecting all information whether it’s stored electronically or on physical media.

A key element of ISO 27001 is that it goes further than simply providing a set of controls that can be assessed for their effectiveness at a point in time. A significant element of the standard is focused on the Management System and the underlying governance and control mechanisms required to operate and manage information and information systems. Achievement of certification requires ongoing and continuous improvement and is a journey rather than a specific destination.

An ISMS audit includes looking at several key elements. These are:

Your information security objectives
A list of all information assets
A list of all stakeholders and their expectations
The risks for each information asset
The controls and mitigation strategies, including implementation plans, for each of the risks
A measurement system so the performance of those controls and strategies can be monitored, maintained and continuously improved

ISO27001 does not specify precisely how the ISMS is to be constructed. It does, however, document what documents are required in order for the ISMS to be ISO27001 compliant.

The standard does not mandate specific actions or controls that organisations must use in order to attain and maintain compliance. It takes a risk-based approach through the identification of organisation and information risks to ensure organisations are addressing those risks that are relevant to their size, operation and management requirements for information security. This allows for flexibility rather than taking a ‘one size fits all’ approach.

Many organisations use ISO 27001 as a guideline to ensure they are following information security best practices. But many others choose to undertake official ISO 27001 certification through independent auditors to give customers, suppliers and other stakeholders assurance that they are following an established and trusted standard.
