On average, you are ready for certification in 4 to 5 months, with a commitment of 3 to 6 hours per week from your team. The exact schedule depends on the size of your organization and the measures that have already been implemented.
Only an internal audit needed?
Our certified lead auditors assess your ISMS and management measures, identify any bottlenecks, and tell you exactly what needs to be done next. This way, you pass the external audit without any surprises. The certificate itself always comes from an independent certification body.

Success story: Effectory
Feedback analytics developers with a team of over 250 people
Months before a project with ISO 27001 and ISO 27701
New security measures implemented
Success during the external audit
The challenge
Effectory processes sensitive employee data for over 1,200 organizations. The challenge was to continuously strengthen the information security system and have it grow with the high demands of customers, without disrupting daily services.
The approach
In close collaboration, we have refined the management system for both ISO 27001 and ISO 27701. With a dedicated point of contact, responsibilities have been clearly defined, processes secured, and the organization prepared for the external audit to achieve certification.
The outcome
Within 6 months, Effectory achieved ISO 27001 certification without any bottlenecks. Security is now demonstrably in order for customers, security questionnaires are answered more quickly, and a solid, future-proof foundation is in place.
Nestor Security conducted the internal audits for both ISO 27001 and ISO 27701 for us. They really strike the right chord for us with a great combination of quality and feasibility. They are pragmatic, think along well with our needs, and the audits are well-organized.

Your questions answered
FAQs
What does an ISO 27001 journey cost?
The costs depend on the size of your organization, the scope of the ISMS and the measures that are already in place. After a free consultation, you will receive a clear, customized price quote.
Realistic bandwidths per organizational size and all cost items are listed in the ISO 27001 Implementation Guide.
How long does an internal audit take?
That depends on the size of your organization, the scope of the ISMS, and the number of locations. For an SME organization, the audit itself is often completed in one to several days, followed by the reporting. During the scoping phase, we will provide you with a concrete schedule in advance, so you know how much time you need to free up for your employees.
How long does the ISO 27001 certification process take?
On average 4 to 5 months. The exact duration depends on the size of your organization and what has already been arranged, and the external audit’s planning also depends on the certifying institution.
In the initial conversation, we discuss what planning is realistic for your organization.
What does the process of our own team require?
On average 3 to 6 hours per week, divided between the colleagues involved. We work not only for you, but also with you. Your team provides the knowledge of your own processes and systems, and is involved in, among other things, the risk analysis workshop.
In the internal audit, we speak with the owner of the ISMS, someone from the management, and the process owners of the components we audit, such as HR, IT, facilities, and purchasing. We agree in advance on who we need when necessary, so that the interviews remain short and focused.
What is the difference between an internal and an external ISO audit?
You organize the internal audit yourself, or have it performed by an independent party such as Nestor Security. The goal is to discover where the ISMS does not yet comply and to improve that before anyone else sees it. The external audit is conducted by a certification body and determines whether you obtain or retain the certificate.
As an external party, we are allowed to conduct your internal audit, but not your certification audit. Those two roles always remain separate, and that is precisely what makes the internal audit so valuable: you get the perspective of an auditor, with nothing at stake.
