ISO 27001
ISO/IEC 27001
ISO/IEC 27001 is an international standard for information security management systems (ISMS), setting requirements for data protection and for monitoring it.
What is ISO 27001 (ISO/IEC 27001)?
ISO/IEC 27001 is an international standard that describes requirements for an information security management system (ISMS). It does not prescribe specific technical settings. Instead, it defines the processes a company must build: how risks to data are identified, who is responsible for what, how incidents are recorded, and how it is verified that protection works.
## How it works
An organization defines the scope of its ISMS, assesses information security risks, selects controls from the standard's annex, and prepares a Statement of Applicability that justifies which controls are implemented and which are not. Internal audits, management review, and continual improvement follow. Certification is issued by an independent accredited body. The certificate is valid for a limited period and is subject to annual surveillance audits.
## Where it is used
In fintech and payment services, partners often request the standard: acquiring banks, processing companies, and large payment providers. Crypto exchanges and custodial wallets use it as evidence of mature processes for key storage and access control. In gambling and betting, the certificate matters when dealing with regulators and large B2B partners where player data protection is important. In dating and nutra, the standard is less common, but having it strengthens trust in the handling of personal data and medical or behavioral information.
## What it affects
Certification affects partnership terms, passing due diligence, and readiness for regulatory inspections. It does not replace GDPR, PCI DSS, or local laws. It complements them. Holding a certificate does not guarantee the absence of data breaches, so it should be seen as proof of processes, not as absolute protection.
## Common mistakes
A common mistake is assuming the certificate automatically covers the entire company. In practice, it applies only to the declared ISMS scope. A second mistake is filling in the Statement of Applicability formally, without a real risk assessment. A third is preparing for the audit once without maintaining the processes. The certification audit gets passed, but a year later the system degrades, and this shows up during a surveillance audit.
FAQ
How does ISO 27001 differ from PCI DSS?
ISO 27001 describes an information security management system as a whole, while PCI DSS is a set of technical requirements for handling payment card data. A company working with cards usually needs both approaches, but they do not replace each other.
How long is an ISO/IEC 27001 certificate valid?
A certificate is usually issued for three years, with annual surveillance audits in between. Specific timelines depend on the certification body and the terms of the contract.
Is ISO 27001 certification required for a license?
It depends directly on the jurisdiction and the type of license. In many cases, the regulator requires compliance with specific data protection rules, and an ISO certificate only helps demonstrate that compliance.
