What is ISO 27001?
ISO/IEC 27001:2022 is the leading international standard for Information Security Management Systems (ISMS). It defines the requirements for establishing, implementing, maintaining, and continually improving an ISMS using the PDCA (Plan-Do-Check-Act) cycle.
Certification is granted by independent accredited bodies and provides assurance to clients, investors, and regulators that the organization manages information security systematically and effectively.

FAQ
Preguntas Frecuentes
An Information Security Management System (ISMS) is a framework of policies, procedures, and controls for managing information security risks systematically. It is important because it provides a structured approach to protecting the confidentiality, integrity, and availability of information.
Typically between 6 and 12 months, depending on the organization's size, system complexity, and current maturity level. Smaller organizations with a good starting point can achieve it in 6 months; larger organizations or those with lower maturity may need 12+ months.
ISO 27001:2022 updates Annex A by reducing controls from 114 to 93, reorganized into 4 themes (organizational, people, physical, technological). It adds 11 new controls including threat intelligence, cloud security, web filtering, and secure coding. Certified organizations had until October 2025 to transition.
It is not legally mandatory in most sectors, but it has become a de facto requirement for: working with large corporations, participating in tenders, meeting sector-specific regulations (DORA, NIS2), attracting investment, and demonstrating security commitment to international clients.
The Statement of Applicability is a key document that lists all 93 Annex A controls, indicating which are applied and which are excluded, with justification. It is one of the most scrutinized documents during the certification audit and must reflect the results of the risk assessment.
We use recognized methodologies such as ISO 27005, NIST SP 800-30, or OCTAVE. The process includes: identification of assets, threats, and vulnerabilities; evaluation of likelihood and impact; determination of risk level; and definition of the treatment plan (mitigate, transfer, accept, or avoid).
The certificate is valid for 3 years. During that period, there are annual surveillance audits (years 1 and 2) and a recertification audit in year 3. Additionally, annual internal audits and periodic management reviews are required.
Yes, it is a recommended strategy. ISO 27701 extends the ISO 27001 ISMS with specific privacy requirements (PIMS). Implementing them together is more efficient since they share much of the documentation framework and controls.
