How we work with you

We treat every engagement as a long-term partnership rather than a one-off delivery. Our approach is organised into four clear phases so that you always know what happens when, who owns which responsibility and which outcomes you can expect.

1. Free initial conversation

We learn about your starting position, your goals and the constraints you operate under. In 30 to 45 minutes we check whether our offering fits your situation, outline possible paths and answer your questions – no obligation attached.

2. Structured assessment

We capture the current state systematically – technically, organisationally and in regulatory terms. You receive a prioritised assessment that clearly names strengths, gaps and action areas and forms the basis for a robust offer.

3. Delivery with a dedicated lead

A senior lead guides you through the delivery with clear milestones, transparent effort and cost planning and a weekly status. All results are documented and remain fully owned by you.

4. Continuous operations & review

After project close, we stay alongside you in operations – via managed-service components, regular reviews, action tracking and proactive recommendations on new threats, regulatory changes or technology shifts.

Frequently asked questions about our services

The questions we are most often asked in first conversations – answered concisely. For anything else, our team is available at hello@sectepe.de or by phone at any time.

How do we start working with SecTepe?
All engagements start with a free initial conversation. You then receive an offer with a clear scope of effort, timeline and outcomes. On request we start with a small pilot to build trust and experience our delivery before moving into full implementation.
What company sizes and sectors do you support?
We work with small and mid-sized businesses as well as with corporate divisions and operators of critical infrastructure (KRITIS). Our core sectors are manufacturing, trades, healthcare, financial services, energy providers, public sector and the DACH mid-market.
Do you work on site, remotely or hybrid?
Both. Assessments, consulting and most managed services run remotely from our German data centres. For on-site work (workshops, training, incident response) we are primarily active in North Rhine-Westphalia, the Rhineland and the Ruhr area and extend our radius as needed.
Which standards and regulations do you cover?
We work to ISO 27001:2022, BSI IT-Grundschutz, TISAX, B3S KRITIS, NIS2, DORA and sector-specific requirements. Our methodology is grounded in recognised frameworks such as NIST CSF, MITRE ATT&CK, OWASP and OSSTMM, combined tailored to each project.
How do you protect the confidentiality of my data?
Confidentiality is anchored contractually and technically. Before every engagement we sign a mutual non-disclosure agreement, data is processed exclusively in German data centres, access is governed by zero-trust policies with multi-factor authentication, and all employees are contractually and GDPR-compliant bound to confidentiality.
