What does an ISO 27001 consultant do for IT Companies?

The role of an ISO 27001 consultant is to help IT companies establish, implement, maintain, and continually improve an Information Security Management System (ISMS) based on the requirements of ISO/IEC 27001. Consultants also help organizations prepare for certification audits in a structured and practical manner.

With the growing use of the internet, we can all agree that nowadays, everything is in the cloud; most of the work is done with one click almost everything is now connected digitally. Much of our work, communication, transactions, and data storage happens online or in the cloud, often with just a few clicks.

With the given searches and the increasing use of digital services, users and organizations generate enormous amounts of data that IT companies are responsible for handling and protecting. As a result, organizations need a resilient information security framework to protect sensitive information from cyberattacks, unauthorized access, data loss, and other security incidents.

ISO/IEC 27001 provides a systematic, risk-based framework for managing information security & can be implemented by organizations of different sizes and industries, including software companies, SaaS providers, IT service providers, cloud service providers, technology startups, and businesses that handle sensitive information.

Despite full knowledge in the IT sector, most IT companies fail ISO 27001; it’s not because they are not well versed with the technology - they fail because most of them don’t know how to perform day-to-day operations against the standard’s control, says Principal Consultant Mr P.K. Dvivedi. 

This is where an experienced ISO 27001 consultant can help. 

What is Data Protection under ISO 27001?

Data protection is a set of measures an organization uses to safeguard sensitive information against loss, unauthorized access, tampering, disclosure, destruction or corruption. 

In the context of ISO/IEC 27001, data protection is not limited to technical measures such as coding or encryption, or system configuration. Instead, it forms part of a broader Information Security Management System (ISMS) that helps an organization systematically identify information security risks and implement appropriate controls.

By implementing an ISO/IEC 27001-compliant ISMS, IT companies ensure users that their data is completely protected & accessible to permitted users, in compliance with all applicable legal or regulatory requirements. ISO consultants help IT companies to implement such standards in a structured way. 

What are the Three Pillars of Information Security?

Information security is commonly explained through three fundamental principles known as the CIA triad: Confidentiality, Integrity, and Availability. 

Confidentiality: It restricts data access to authorized individuals, systems, or processes.

For an IT company, how this helps: 

• Save employee records

• Customer database

• All Financial information

• Passwords & Credentials

• Integrity: It aims to preserve data accuracy; information remains accurate & prevent unauthorized modifications.

• Availability: It ensures data is accessible whenever required and must be accessible by authorized users only. 

An ISO 27001 consultant helps organizations address these principles by establishing an appropriate ISMS, identifying information security risks, and implementing controls suited to the organization's needs.

Why do IT Organizations need an Information Security Management System (ISMS)?

An Information Security Management System (ISMS) is a structured framework of policies, processes, procedures, responsibilities, and controls designed to help an organization manage information security risks.

In professional technical terms, if one can opt for ISO 27001 certification, consultancy services can help organizations reduce breach costs by 30%, resulting in more business opportunities worldwide.

As we all know, with fast-growing technology, everyone is well versed with the use of the internet, and they rely on IT companies for services. As they are working as middlemen between users and service providers. IT companies need an ISMS; they are the centre of client data flows, data repositories, cloud data, and personal information. At this stage, they can’t afford data breaches for the clients they are serving. 

That’s why it becomes mandatory to take the help of an ISO 27001 consultant to decode the instructions and implement them in a more suitable way 

Organizations can implement the following Information Security Controls, also known as Annex A Controls, to effectively manage, store, and protect users’ sensitive data. ISO/IEC 27001:2022 includes 93 information security controls in Annex A, organized into four control themes. These are as follows:

Control Category What It Covers

Organizational Controls Policies, roles, supplier and third-party risk, incident management

Technological Controls Access control, encryption, network security, secure development

People Controls Screening, training, awareness, disciplinary process

Physical Controls Facility access, equipment security, secure disposal

The specific controls an organization applies depend on its information security risks, scope, and Statement of Applicability (SoA).

Why ISO/IEC 27001 Consulting Services Matter?

First of all, we need to understand that an ISO 27001 consultant and a certification body have different roles.

An ISO 27001 consultant helps an organization establish and improve its ISMS and prepare for the certification audit. A certification body independently audits the organization's ISMS and makes the certification decision when the applicable requirements are met.
