Last position:
Project Manager (Enterprise Cloud Governance) at CompuGroup Medical SE & Co. KGaA
Short description: Lead a group-wide project to establish standardized cloud governance for Microsoft Azure, including policies, security and compliance controls, automation, and cost and operations control while preserving the autonomy of decentralized business units within regulatory boundaries.
Tasks and activities:
Overall responsibility for the design, setup, and implementation of an enterprise-wide cloud governance structure (Azure), incl. target picture, roadmap, and operating model.
Management of internal and external stakeholders (C-level, IT, Security, Compliance, Cloud Architecture, DevOps) incl. decision-making and escalation management.
Planning and facilitation of workshops on cloud strategy, governance principles, and the design of areas such as Identity, Connectivity, and Platform Management.
Definition, implementation, and rollout of cloud policies (Azure Policy / custom policies), security standards, and compliance requirements (including GDPR, ISO 27001, BSI C5).
Building a cloud governance framework aligned with the Azure Cloud Adoption Framework (CAF), incl. landing zone and guardrail concepts.
Introduction of automation solutions for governance, security, and cost control (policy/control automation, IaC, CI/CD-based control mechanisms).
Implementation of cloud security and compliance monitoring mechanisms as well as continuous improvement processes.

About the technology
Cloud compliance standard
BSI C5, short for Cloud Computing Compliance Criteria Catalogue, is a framework from the German Federal Office for Information Security. It defines requirements and audit criteria for secure cloud services. Companies use it to assess whether a provider’s controls, processes and evidence support trustworthy operation.
What C5 covers
The catalogue addresses governance, organisation, physical security, operations, identity and access management, resilience, encryption, incident handling and data protection. It connects technical safeguards with documented responsibilities and control processes. A C5 engagement often produces a structured assessment, evidence set or audit-ready report.
Ecosystem and tooling
C5 work involves cloud environments, security management systems and audit workflows. Strong professionals may work with:
- Control matrices mapped to C5 requirements
- Risk registers, policies and process documentation
- Identity, logging, encryption and backup evidence
- Cloud security monitoring and ticketing systems
- Audit portals and evidence repositories
When companies need experts
Companies often bring in freelance expertise before a first C5 audit, during a provider assessment or when expanding a cloud service. Germany-based organisations may need support aligning internal teams, cloud providers and external auditors. Remote collaboration works well for document reviews and control testing, while workshops may benefit from on-site sessions and German-language communication.
Typical deliverables
A specialist can define the assessment scope, map controls to responsible teams and identify missing evidence. Common deliverables include a readiness assessment, control descriptions, risk treatment plans, evidence requests, remediation tracking and management briefings. The work may cover infrastructure, software services or business processes that support the cloud offering.
What strong professionals bring
The best fit combines knowledge of BSI C5 with practical cloud security and audit experience. Look for clear reasoning, careful evidence handling and the ability to explain control gaps to technical and business stakeholders. Relevant adjacent skills include ISO 27001, information security management, data protection, vendor risk, business continuity and cloud architecture. Ask for examples of comparable assessments and how findings were turned into verifiable improvements.
Frequently asked questions
The facts hiring teams ask for most often when it comes to BSI C5.
BSI C5 is used to assess the security controls of cloud computing services. It gives customers, providers and auditors a common structure for reviewing governance, operations, resilience and technical safeguards.
BSI C5 focuses specifically on cloud services and includes criteria for describing and testing provider controls. ISO 27001 is a broader management-system standard, so companies often use both when they need cloud-specific evidence alongside an established information security framework.
A strong BSI C5 specialist usually understands cloud security, ISO 27001, risk management and audit preparation. Experience with identity management, logging, encryption, data protection and business continuity is also valuable.
The right level depends on the scope, evidence quality and audit stage. A C5 specialist should have handled comparable control assessments and be able to distinguish documentation gaps from weaknesses in actual cloud operations.
Much of a BSI C5 assessment can be completed remotely through interviews, evidence reviews and shared documentation. On-site workshops can still help with sensitive processes, stakeholder alignment or remediation planning, and German-language communication may matter for local teams.
Ask how the Cloud Computing Compliance Criteria Catalogue will be mapped to your services, controls and evidence owners. Also clarify the expected deliverables, auditor interaction, access requirements and approach to unresolved findings.
High-quality BSI C5 work is traceable from each requirement to an accountable control, reliable evidence and a clear test result. The specialist should document assumptions, separate observations from risks and explain practical remediation without overstating compliance.
BSI C5 is primarily designed for cloud service providers, but customers can use it to evaluate provider assurance and procurement requirements. Internal security, risk and compliance teams may also rely on its criteria when reviewing cloud-hosted services.
