ISMS Scope

Document ID: ISO-001 Document owner: Jan Marc Castlunger (ISO) Classification: Confidential Version: 1.0 Approved: March 2026 Next review: March 2027 Framework: ISO 27001 (4.1, 4.2, 4.3)


1. Organisation

Field Detail
Legal entity CTW Data Solutions GmbH
Trade name / Product Quick-ID (quick-id.com)
Registered office Germany
CEO / ISO Jan Marc Castlunger
CTO / DPO Sebastian Windeck
Employees 4-10
Industry Identity verification technology / SaaS
Customers 50+ active API customers globally

2. Context of the Organisation (Clause 4.1)

2.1 External Issues

Category Issue Impact on ISMS
Regulatory GDPR / DSGVO — stringent data protection requirements for EU personal data processing Mandatory DPA compliance, 72h breach notification, DPO appointment, Art. 30 register
Regulatory BDSG — German federal data protection law supplementing GDPR Additional requirements for employee data and DPO obligations
Regulatory EU AI Act (Regulation 2024/1689) — AI systems regulation entering force 2025-2027 Quick-ID's document verification involves automated decision-support; classification assessment required (see Legal Register)
Regulatory eIDAS 2.0 — EU digital identity framework Future opportunity; may require additional compliance for EU Digital Identity Wallet integration
Market Enterprise customers increasingly require ISO 27001 + SOC 2 as procurement prerequisites Direct driver for ISMS certification; competitive differentiation
Market Identity verification market is highly competitive with well-funded incumbents Security posture and certifications are key differentiators
Technology Rapid evolution of AI/ML capabilities for document fraud Continuous need to update detection models and security controls
Technology Cloud provider dependency (Microsoft Azure) Single cloud vendor risk; mitigated by Terraform IaC portability
Threat landscape Rising sophistication of phishing, credential theft, and supply chain attacks Continuous need for security awareness, MFA enforcement, and dependency scanning
Economic Startup/scale-up environment with limited budget Prioritisation of security investments; lean ISMS approach

2.2 Internal Issues

Category Issue Impact on ISMS
Organisation size Small team (4-10 employees) Limited segregation of duties; key person dependency; dual-role holders (CTO=DPO, CEO=ISO)
Work model 100% remote / distributed team No physical office to secure; BYOD policy required; reliance on cloud-based collaboration
Technical expertise Deep technical competence in core team (AI, cloud, security) Enables lean operations but creates key person risk if personnel leave
Key person dependency Critical knowledge concentrated in CEO (Jan Marc) and CTO (Sebastian) Documented in risk register (R10); mitigated by runbook documentation
Culture Engineering-first, security-aware culture Positive: team is receptive to security controls; challenge: formalising what was previously informal
Growth Scaling from startup to enterprise-ready SaaS ISMS must scale with growth; processes need to work at 4 people and at 20+
Infrastructure Cloud-native, IaC-managed (Terraform), containerised (AKS) Enables reproducible environments and auditable infrastructure changes
Data sensitivity Processing government-issued ID documents (passports, ID cards) Highest data sensitivity category; in-memory-only processing is a key control
