Whether you’re starting your journey or advancing your career, our ISO/IEC 27001 training courses and certifications equip you with practical, in-demand skills to protect data, manage information risks, and enhance digital trust.

Why is ISO/IEC 27001 Important?

ISO/IEC 27001 helps organizations implement an Information Security Management System (ISMS) that protects the confidentiality, integrity, and availability of information through a structured risk management process. By complying with ISO/IEC 27001, organizations can identify, assess, and treat information security risks effectively.

Certified ISO/IEC 27001 professionals demonstrate the expertise required to support organizations in implementing information security policies and procedures tailored to their business needs while promoting continual improvement of the management system and organizational operations.

Certification also proves your ability to integrate an ISMS into organizational processes and ensure the intended security outcomes are consistently achieved.

ISO/IEC 27001 Annex A Controls

ISO/IEC 27001 was updated in 2022 to address modern cybersecurity challenges. The revision focused on Annex A, reducing the number of controls from 114 to 93 and organizing them into four key themes.

The Four Themes of ISO/IEC 27001:2022 Controls

Organizational Controls

• Develop and implement comprehensive information security policies.
• Establish incident management processes for reporting and responding to security incidents.

People Controls

• Provide security awareness training for employees.
• Conduct background screening during recruitment where appropriate.

Physical Controls

• Protect physical access to information processing facilities.
• Safeguard equipment from theft, loss, or damage.

Technological Controls

• Restrict access to systems based on user roles.
• Use cryptography to protect sensitive information.

The Main Changes Between ISO/IEC 27001:2013 and ISO/IEC 27001:2022

The 2022 edition introduces significant updates to reflect today’s cybersecurity and privacy landscape. The standard now places greater emphasis on information security, cybersecurity, and privacy protection.

Annex A has been simplified from 114 controls across 14 categories to 93 controls grouped into four categories: Organizational, People, Physical, and Technological Controls. These changes make the standard more practical, streamlined, and aligned with current security practices.
