Complete process to obtain certification
All six services are handled in a single approach, with a dedicated consultant acting as the point of contact. On average, you will be ready for the external audit in 4 to 5 months.
The external audit is always carried out by an independent certifying body. You pay directly to that body, starting at €6,000. We ensure that you are prepared for it.
Would you rather do some of the work yourself?
Then only take the services you still need. Each service has a fixed price, without additional charges.

Introducing measures

Internal audit
An independent audit of your ISMS by a certified lead auditor.
Management review

What you actually pay, side by side

Success story of Effectory
Feedback analytics developers with a team of more than 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.

Hourly fee, or a fixed price in advance
With many consulting firms, you only find out afterwards what ISO 27001 cost. We work with fixed prices without additional charges, so you can set your budget in advance.

The communication lines with Nestor Security were short. The organization has a pragmatic mindset and is a down-to-earth party to do business with. As a result, the process went smoothly and fairly quickly.
We prefer to work together as much as possible regionally and like to hold meetings face-to-face. When you look at partners in the North, there are still a few left, and Nestor Security stands out above the rest.
Nestor Security has provided the internal audits of ISO 27001 and ISO 27701 for us. They really hit the mark for us with a good combination of quality and practicality. They are pragmatic, think well with our needs, and the audits are well-managed.
Your questions answered
FAQs
What does the guarantee of success entail?
If you choose the complete process and the certifying body finds a significant deviation in part of the ISMS that we have overseen during the external audit, we will help you without additional costs until the external audit is completed. So far, all our clients have passed the external audit.
Can I also purchase individual services?
Yes. You can purchase each service separately, from scope definition and gap analysis to setting up your ISMS, implementing measures, internal audit and management review.
We do not perform the external audit ourselves. That is always carried out by an independent certifying body, but we will prepare you for it.
How quickly will I receive a quote?
After the initial consultation, you will receive a fixed price quote for each service within two working days. This is non-binding, and the prices do not change as long as the scope remains the same.
What does the certifying institution cost?
The certifying institution charges per audit day. An organization with 25 to 45 employees is likely to spend four to five audit days for stages 1 and 2 combined, at a daily rate of roughly €1,000 to €1,500.
We request quotes from multiple accredited institutions and help you choose the right one.
What does ISO 27001 certification cost in total?
For most SME organizations and SaaS companies, the total investment is between €16,000 and €28,000. This includes our guidance, the internal audit, and the external audit by the certifying body.
If you have already arranged for part of the work, you will only take on the services you still need, and the total cost will be lower.
Is it cheaper to implement ISO 27001 on your own?
On paper, yes; in practice, often not. Without guidance, you don’t pay for consulting hours, but you put a lot more of your own time into it. A small business can quickly spend 200 to 400 internal hours, and a re-audit after deviations costs additional audit days.
A middle ground is also possible. You do part of the work yourself and only outsource the difficult tasks, such as setting up the ISMS or the internal audit.
What costs are there after certification?
The certificate is valid for three years. In years 1 and 2, a surveillance audit takes place, in year 3 a re-certification. In addition, an internal audit and a management review are mandatory every year.
For a SME organization, that amounts to approximately €4,000 to €8,000 per year in external costs. With ISMS management, we take over that work for a fixed annual fee from you.
How long will it take before we are certified?
On average, 4 to 5 months until the external audit. The certifying institution often has a waiting period of a few weeks, which is why we request the quotes already in the first phase.
