ISO/IEC 27001:2022 internal audit

We audit your Information Security Management System with the same rigour the certification body will apply, so nothing surprises you on the real audit day.

Standard: ISO/IEC 27001:2022 · clause 9.2
Duration: 3 to 6 weeks
Model: Internal or supplier audit
Output: Report with nonconformities and plan

The problem

The standard requires internal audits at planned intervals, and it is not paperwork: it is the mechanism that catches deviations before a third party does. It also works as a dress rehearsal if you are not certified yet, and as a control over critical suppliers who claim compliance that nobody has verified.

What it includes

Programa de auditoría

Planificación del ciclo anual: qué procesos se auditan, cuándo, con qué criterios y con qué independencia respecto de quien los opera.

Revisión documental

Contraste del cuerpo documental —política, procedimientos, Declaración de Aplicabilidad y registros— contra lo que la norma exige en cada cláusula.

Auditoría de campo

Entrevistas, observación y muestreo de evidencia real: no basta con que el procedimiento exista, hay que comprobar que se ejecuta como está escrito.

Verificación de controles del Anexo A

Revisión técnica de los controles declarados aplicables, incluidos accesos, criptografía, respaldos, registro, desarrollo seguro y gestión de proveedores.

Hallazgos clasificados

No conformidades mayores, menores y observaciones, cada una con la cláusula incumplida, la evidencia que la respalda y su impacto.

Plan de acciones correctivas

Análisis de causa raíz y acciones con responsable y plazo, redactadas para cerrar el hallazgo y no solo para responderlo.

Seguimiento del cierre

Verificación posterior de que las acciones se implementaron y fueron eficaces, con acta de cierre por hallazgo.

Auditoría a proveedores

La misma metodología aplicada a terceros críticos que tratan tu información y declaran cumplir la norma.

Note

We audit, we do not certify. Certification is issued by an accredited independent body, and that independence is exactly what gives it value. Our role is internal: to find what fails while it can still be fixed without ending up in an official report.
