About us

Not an anonymous consulting team, but two people with clear responsibility — from the first analysis to audit-ready evidence.

What we stand for

  • • Clear priorities instead of page-long assessments
  • • Security and compliance structures that work in real operations
  • • Evidence that actually holds up in an audit

• Computer science & IT security / information security
• Risk management & assessments
• Management and process management
• Industry / IT 4.0 and SCADA-adjacent topics
• Audits & consulting
• Cloud technologies (IaaS, PaaS, SaaS, hybrid)
