ISO 27001

The standard your customers keep asking about.

No law makes a software company certify to ISO 27001; a customer's renewal, a tender or a bank under DORA does, and the first number to know is what the audit takes for a company of your size.

People doing work under your control, in ISMS scope

Count contractors and freelancers, not just employees. The 2024 edition is explicit about this, and it is the mistake that most often pushes a company into the next band.

For 25 people the certification audit is 7 auditor days under ISO/IEC 27006 Annex B: €8,400 to €12,600 for the initial audit and €14,000 to €21,000 for the three-year cycle, at the day rates accredited bodies in Europe charge, audit fees only.
