ISO / IEC 27001 audit

Expert opinion with added value.

Tailor-made IT security management

ISO / IEC 27001 is the international de facto standard for information security in public authorities and companies. Certification is already mandatory for federal authorities, voluntary for companies and other institutions. In view of the intense competition in the IT sector, ISO 27001 is also rapidly gaining importance in the private sector. We accompany you in all phases on the way to certification, either in an advisory capacity or in the course of an audit. Of course, we also carry out ISO 27001 audits for energy suppliers or operators of critical infrastructures according to the Energy Industry Act (EnWG).

Systematic and goal-oriented

IT security management is a field of work with many interlocking aspects. Through numerous projects in the industrial and administrative sectors, we can draw on extensive practical experience.
Our clients not only increase the IT security level of their organisation, but also improve operational data protection in the ongoing optimisation process. Certification according to ISO / IEC 27001 is therefore straightforward and economical. We work closely with DAkkS-accredited certification bodies and the German Federal Office for Information Security (BSI).


More than information technology

The basis for certification according to ISO / IEC 27001 is a detailed assessment of the existing information security management system (ISMS). In addition to concrete implementation measures, the assessment focuses in particular on hazard identification as well as measurability and controllability. The aim is to continuously improve the ISMS and update it on the basis of current risk analyses. Special offers are available for energy suppliers and network operators in the run-up to the IT security catalogue pursuant to Section 11 (1a) EnWG.
