ISO 27001
Information Security Management System
What is ISO 27001?
ISO 27001 is an international standard that defines the requirements for an Information Security Management System (ISMS). It is the most widely recognized standard for protecting both digital and physical data.
The standard focuses on identifying risks, securing information assets, and implementing effective safeguards to prevent breaches of confidentiality, integrity, and availability of data.
What Are the Benefits of Implementing ISO 27001?
In an era of growing cyber threats and strict data protection regulations (such as GDPR), ISO 27001 certification is not only a competitive advantage – it is the foundation of responsible information management.
Benefits include:
- protection against cyberattacks, data leaks, and sabotage
- streamlined processes for data access and storage
- increased trust from clients and partners
- fulfillment of contractual and tender requirements
better preparation for audits and inspections (e.g. GDPR, financial regulators, ISO 9001)
Who Should Consider ISO 27001?
ISO 27001 applies to any organization that processes data, regardless of size. It is especially recommended for:
- IT and software development companies
- fintech, banking, and insurance institutions
- e-commerce and retail businesses
- public administration and healthcare sectors
- accounting firms and law offices
- companies handling customer data (e.g. CRM systems, SaaS providers)
What Does ISO 27001 Implementation Involve?

Frequently Asked Questions
Is ISO 27001 mandatory?
No, ISO 27001 is not legally required. However, it is increasingly demanded in tenders, contracts with large enterprises, financial institutions, and EU-funded projects. It is also a strong asset when acquiring international clients.
How long does ISO 27001 implementation take?
It depends on the organization’s size, number of processes, and IT complexity. Typically, it takes 4 to 12 weeks, but for larger organizations the process may take several months.
Do I need an internal security department?
No. Many companies choose to outsource implementation and oversight of the system. You can work with external experts for consulting, training, and internal auditing.
Is ISO 27001 enough to comply with GDPR?
Not entirely, but it helps significantly. ISO 27001 covers the most technical and organizational requirements of the GDPR. Full compliance also depends on legal processes and data protection documentation.
Can ISO 27001 be combined with other standards?
Yes. Integrated systems are common, for example ISO 27001 + ISO 9001 (quality) or ISO 27001 + ISO 22301 (business continuity). This creates a unified and scalable management system.
