Our Competencies
Choose the area that fits your requirements
Cloud data residency has become a critical compliance challenge since Schrems II and the EU-US Data Privacy Framework for organizations in regulated industries. Server location in the EU alone is insufficient — the US CLOUD Act enables American authorities to access data held by US providers regardless of where it is stored. Effective data residency strategies therefore require a comprehensive governance framework: Transfer Impact Assessments, customer-managed encryption, EU geo-location controls, and continuous compliance monitoring. We develop tailored cloud data residency solutions that balance GDPR requirements, data sovereignty, and operational flexibility.
Cloud environments demand well-designed encryption concepts covering data at rest, in transit and in use. From AES-256 and BYOK to HSM integration — regulatory requirements from GDPR, BSI C5 and industry-specific mandates determine which encryption standards your organisation must implement. We support you in analysing your encryption requirements, selecting suitable key management solutions and implementing GDPR-compliant encryption architectures for multi-cloud environments.
Cloud migration compliance is a critical challenge for regulated organizations moving their IT infrastructure to the cloud. BaFin requirements for cloud outsourcing, GDPR-compliant data migration, and DORA mandates for digital operational resilience demand well-designed governance frameworks. We develop tailored cloud migration compliance solutions that meet regulatory requirements, secure exit strategies, and ensure your cloud transformation is sustainable and supervisory-compliant.
Selecting and monitoring cloud providers presents organizations with growing regulatory challenges. Whether BSI C5 attestation, BaFin requirements for cloud outsourcing, or industry-specific security standards — a structured evaluation of your cloud service providers is essential. We develop tailored vendor assessment processes that meet regulatory requirements while strengthening operational collaboration with cloud providers. From initial due diligence screening through security assessment to continuous monitoring — our solutions create transparency about risks and compliance status across your cloud supply chain.
Financial institutions face the challenge of using cloud services in compliance with BaFin regulations while meeting the requirements of DORA, MaRisk, and EBA guidelines. Outsourcing to cloud providers requires structured risk analyses, materiality assessments, and robust contract design — from audit rights and data protection to exit strategies. We support banks, insurers, and financial service providers throughout their entire cloud compliance journey: from strategic assessment through BaFin-compliant implementation to ongoing monitoring of your cloud providers.
Hybrid cloud environments present organizations with a core challenge: How do you ensure consistent compliance across on-premises systems, public cloud services and edge infrastructure? Differing security standards, fragmented policies and unclear responsibilities create compliance gaps — especially for GDPR, BSI C5 and NIS2. We develop unified hybrid cloud governance frameworks that integrate workload classification, data residency requirements and automated policy enforcement across all your cloud platforms.
We help teams govern several cloud providers and their on-premises dependencies: a service inventory, named control owners, testable policies and evidence for review. Start with one business service, validate the operating process and expand the approach where it works.
Securing modern cloud environments requires structured security frameworks such as BSI C5, ISO 27017, and CSA STAR that go beyond traditional perimeter-based security. Successful implementation demands comprehensive frameworks covering multi-cloud governance, container security, Zero Trust architecture, and DevSecOps integration. We support you in selecting, implementing, and auditing the right cloud security frameworks — from gap analysis through control implementation to certification preparation for BSI C5, SOC 2, and ISO 27017.
Frequently Asked Questions about Cloud Security Architecture & SLA Management
What does a cloud security architecture include and why are default configurations insufficient?
A cloud security architecture connects identities, networks, data, workloads and operational controls. Evaluate each service configuration against the workload risks and applicable obligations. Provider defaults are a starting point to assess, not proof that the workload is protected. The review should identify required customer controls and how they will be tested.
How does the shared responsibility model work and where is the boundary between cloud provider and enterprise?
Responsibility depends on the service model, provider terms and configuration. For each service, document who configures access, protects data, collects logs, performs recovery and responds to incidents. Include customer duties identified in provider assurance reports. Test the boundaries with an incident or recovery scenario and assign unresolved responsibilities explicitly.
Which SLA metrics are business-critical for cloud services and how are they monitored?
Start with the supported business service. Define availability measurement windows, exclusions, response and restoration commitments, measurement sources and escalation contacts. RTO and RPO are recovery objectives whose achievement needs exercise evidence; a dashboard alone cannot demonstrate recovery capability. Review observed performance alongside contractual service credits and customer recovery dependencies.
How do you integrate Zero Trust principles into an existing cloud security architecture?
Zero Trust follows the principle of 'never trust, always verify' — every access request is authenticated and authorised regardless of network location. Integration starts with an inventory of all identities, devices and data flows. Then micro-segmentation, context-based access control and continuous verification are implemented. In existing cloud environments, this happens in phases: first identity-centric controls, then network segmentation, finally workload protection. ADVISORI guides this process from architecture planning to implementation with measurable milestones.
What regulatory requirements apply to cloud security architectures in the financial sector?
Determine the entity and service scope first. DORA has applied since January 2025 and covers ICT risk, resilience testing and ICT third-party risk. Institutions subject to its ICT risk-management requirements are excluded from BAIT. Translate the applicable obligations into service-specific controls, contracts and evidence; do not stack every historical regulatory framework onto each cloud service.
How do you manage SLAs effectively in multi-cloud environments with different providers?
Multi-cloud environments require a unified SLA governance framework that harmonises provider-specific differences. ADVISORI develops standardised metrics that are comparable across AWS, Azure and GCP. The framework includes vendor scorecards, automated performance reports, escalation paths and contractual safeguards for service outages. The crucial factor is correlating technical SLA metrics with business impact — 15 minutes of payment service downtime has very different consequences than the same outage on an internal reporting tool.
What does a professional cloud security architecture cost and when does the investment pay off?
Estimate effort from the number of workloads and providers, existing architecture documentation, contract access and the depth of testing. Agree deliverables and dependencies before fixing a schedule. Assess value through measurable control gaps closed, reduced manual work and demonstrated recovery capability. An industry-wide breach-cost average does not establish the return on this project.
