ISO 27001 Certification: Benefits and Standards

  • October 6, 2021

Every company faces a variety of unique information security challenges. To answer these challenges, ISO 27001, one of the world’s most popular information security standards, was created. Formally known as ISO/IEC 27001:2005, it is an information security management system or ISMS. It provides a framework of procedures and policies which include the legal, physical, and technical controls for an organization’s information risk management processes. The goal of ISO 27001 is to provide a model for implementing, operating, monitoring, maintaining, and updating an ISMS.


Benefits of Certification

Completing ISO 27001 certification will have numerous benefits for your company. It will demonstrate a robust business model, a future-proofed organization, and superior ISMS.

Retaining Clients

A growing number of customers and other stakeholders care about how their sensitive and important information is handled. The risks of a data breach are high. Your customers cannot ‘take your word for it.’ They need assurance that their data will be handled with the utmost care and security. ISO 27001 certification provides that assurance. It will help you retain your customers and give you a competitive advantage when pursuing new business.

Avoiding Fines

If you are a global company, chances are you are doing business in regions like Europe that impose steep fines for data breaches. For example, under GDPR, you could face up to a 4% fine over the annual turnover for security lapses. While a hefty fine can be ruinous, even a small fine or a warning can cause harm to the reputation of your company.

Improved Process

Going through the process of ISO 27001 will help improve your security-related documentation and ensure your staff has clear procedures to follow to keep data safe. It requires you to put the framework in place procedures for change management, development, testing, and operations environments, malware controls, and data backup. ISO 27001 demonstrates you have planned for any possible attacks and have a business continuity plan in place.

Legal and Commercial Responsibilities

Your organization will have regulatory and contractual obligations to the data it stores on customers’ behalf. ISO 27001 requires you to document how your organization approaches these obligations. Thus, letting stakeholders know the business is future-proofed.


Certification Process

The process for ISO 27001 certification can take up to several years and involve multiple stakeholders both within your organization and externally. You will need a formal approach, and before beginning the process, your ISMS must be fully mature and cover all areas of risk. You must build trust before and throughout the certification process. The process itself is divided into three phases:

  1. A certification body is hired to conduct a review of the ISMS. This organization will look for the primary documentation of the system. 
  2. A more in-depth audit is performed by the certification body. During this phase, individual parts of ISO 27001 are checked against the ISMS. There must be evidence that all policies and procedures are being followed. A lead auditor will determine if the organization has earned its certification. 
  3. Compliance must be maintained. The certification body will schedule follow-up audits to make sure your organization is still in compliance.


Requirements for ISO27001

ISO 27001 is broken down into 12 separate sections, including scope, leadership, planning, performance evaluations, improvement, and more. Fourteen different controls are then audited for certification.

1.Information Security Policies

This covers and reviews how policies should be written in the ISMS.

2.Organization of Information Security

The parts of your organization that are responsible for what tasks and actions must be demonstrated.

3.Human Resource Security

This covers how to inform employees about cybersecurity when starting, leaving, or changing positions.

4.Asset Management

You must describe your processes for managing data assets and how they are protected and secured.

5.Access Control

This provides guidance on employee access to different types of data.


Best practices for encryption must be put into place and will be reviewed.

7.Physical and Environmental Security

Show how your organization secures buildings and internal equipment.

8.Operations Security

You must show that your data is collected and stored securely.

9.Communications Security

This covers the security of all the transmissions, email, chat, or videoconferencing, in your network.

10.System Acquisition, Development, and Maintenance

13.Information Security Aspects of Business Continuity Management
