What is ISO 27001?

ISO 27001 is the world's leading international standard for Information Security Management Systems (ISMS). Published by the International Organization for Standardization (ISO), it provides a systematic approach to managing sensitive company information and ensuring its security.

Why Does ISO 27001 Matter?

In today's digital landscape, organizations face unprecedented security challenges:

• Data breaches cost companies an average of $4.45 million per incident
• Regulatory requirements demand proof of security practices
• Customer trust depends on demonstrable security measures
• Supply chain security requires third-party validation

ISO 27001 certification demonstrates to stakeholders that your organization takes information security seriously and has implemented internationally recognized best practices.

The Core Concept: ISMS

An Information Security Management System (ISMS) is not just a set of policies—it's a holistic framework that encompasses:

1. People - Training, awareness, and defined responsibilities
2. Processes - Documented procedures for handling information
3. Technology - Technical controls and security tools
4. Continuous Improvement - Regular reviews and updates
