Cyso Cloud

  • OpenStack public IaaS on EU hardware

    Vanilla OpenStack compute (roughly 2–64 vCPUs and up to 512 GB RAM flavors), NVMe-backed ephemeral and block volumes, dashboard plus OpenStack APIs/CLI. Deployed on Cyso-managed hardware in Amsterdam and Frankfurt with three availability zones per region so multi-AZ designs are first-class.

  • S3-compatible NVMe object storage

    Region-scoped object storage with triple-disk redundancy, versioning, lifecycle rules, object lock, pre-signed URLs, and standard S3 clients (AWS CLI, Rclone, MinIO mc, SDKs). Data and replicas stay in the selected AMS or FRA region; default server-side encryption at rest is not applied—plan client-side or customer-key approaches for sensitive objects.

  • Enterprise Managed Kubernetes (KCSP)

    CNCF Kubernetes Certified Service Provider managed control planes with multi-version support, automated upgrades, worker groups (including GPU/high-memory options), HPA/VPA/node autoscaling, Garden Linux workers, Terraform/kubectl/k9s workflows, and cluster hibernation to scale workers to zero on a schedule.

  • European networking and multi-AZ design

    VPC-style private networks, security groups as virtual firewalls, load balancers with health checks, floating/reserved IPs, Anycast DNS, IPv6 dual-stack, native edge DDoS mitigation, and Direct Connect-style private links. SLA text targets 99.99% monthly uptime for listed compute, volume, object, and networking services when multi-AZ conditions are met.

  • Private cloud and wholesale options

    Same OpenStack-based stack can be deployed as a private cloud on customer data-centre hardware (including VMware-alternative messaging) or white-label/wholesale models for partners—useful when public multi-tenant regions are not enough for isolation or residency policy.

IONOS

  • Virtual Data Center Designer and IaaS compute

    Build isolated virtual data centers in the browser or via Cloud API: dedicated-core servers, vCPU servers, and Cubes with attached NVMe. Live vertical scaling is supported on many Linux images for cores, RAM, NICs, and volumes without a full rebuild. Locations span DE (Berlin, Frankfurt, Karlsruhe), FR, ES, UK, and US.

  • Managed Kubernetes without a separate control-plane fee

    Automated cluster and node-pool setup with geo-redundant control plane, admin API access, and optional node auto-scaling. IONOS documents the managed control plane as free of charge; you pay for the underlying compute, storage, and network only—useful for staging and production clusters on the same contract.

  • S3-compatible Object Storage across EU and US endpoints

    Contract-included Object Storage with S3 API compatibility, versioning, object lock, SSE-S3/SSE-C, and lifecycle rules. Documented endpoints include Frankfurt, Berlin, Logroño, and Lenexa (US). German object-storage locations are listed with BSI IT-Grundschutz compliance notes in the service catalog.

  • Managed databases, GPU VMs, and Berlin-hosted AI Model Hub

    DBaaS for PostgreSQL, MongoDB, MariaDB, and in-memory DB; Cloud GPU VMs (NVIDIA H200 templates) in Frankfurt; AI Model Hub with OpenAI-compatible APIs, RAG/vector support, and vendor-stated processing exclusively in Germany (Berlin). Fits teams that want European inference without standing up their own GPU estate.

  • Domains, web hosting, and personal consultant for SMBs

    Classic IONOS portfolio: domain registration, shared/VPS/dedicated hosting, site builders, and optional Microsoft 365 or Google Workspace. Differentiator for non-cloud buyers is a dedicated personal consultant plus 24/7 support channels—not pure ticket-only self-serve hosting.

Assurance & compliance: Cyso Cloud vs IONOS
Assurance & complianceLogo: Cyso CloudCyso CloudLogo: IONOSIONOS
Independent security / no-logs audit
Not found

Security measures and pen-testing philosophy are described; no public independent no-logs or IaaS audit report found beyond ISMS certs.

Partial

BSI C5 Type 1 (2023 announcement) and IT-Grundschutz ISMS claims after external audit; not a public no-logs VPN-style audit. Request current reports and scope.

ISO 27001
Vendor claimed

Vendor publishes ISO/IEC 27001 certificate PDF via Trust Centre / certifications (listed expiry into 2028). Not re-checked on an independent registry for this draft.

Vendor claimed

Vendor FAQ/about materials state ISO 27001 for data centers / security posture; facility partner cert PDFs also referenced on location pages. Independent cert registry entry not re-verified here.

SOC 2 / SOC 3
Not found

Certifications page explains SOC 2 Type II generally; no clear statement that Cyso currently holds a published SOC 2 report.

Not found

SOC/SSAE-style attestations appear for some facility operators (e.g. Equinix listings). No clear IONOS product-level SOC 2 claim found on primary pages reviewed.

GDPR / EU data protection
Vendor claimed

EU legal entity; AMS/FRA residency claims; Trust Centre GDPR section. Obtain DPA and TOMs for controller/processor mapping.

Vendor claimed

German controller/processor entities; EU location options; vendor GDPR statements. Residency still depends on selected regions and subprocessors.

US CLOUD Act exposure (indicative)
Partial

EuropeanStack assessment: EU entity, no known US parent, primary IaaS claimed on self-operated NL/DE hardware (not AWS/GCP/Azure). Partial because no full public subprocessor schedule and ancillary SaaS (e.g. PostHog analytics, Atlassian-linked status) may involve non-EU providers. Not legal advice.

Partial

German SE / no known US parent, but US subsidiaries, US host regions (LAS/EWR/MCI), Equinix facility partnership, optional Microsoft/Google products, Acronis-powered backup. Not legal advice.

Data processing agreement (B2B)
Vendor claimed

Marketing (e.g. Azure alternative pages) states Cyso signs a DPA under Dutch law; confirm current template and subprocessor annex in contracting.

Vendor claimed

Hosting DPA via account privacy flows; IONOS Cloud AVV via account manager / contract docs. Confirm entity and service annex.

NEN 7510 (Dutch healthcare information security)
Vendor claimed

Vendor publishes NEN 7510 certificate PDF on certifications/Trust Centre pages.

Not listed
EU AI Act
Not applicable

IaaS/infrastructure platform, not an AI system product.

Partial

Relevant mainly to AI Model Hub (docs discuss governance/compliance). Core hosting/IaaS is not AI-product-centric; treat AI Act as service-specific diligence.

BSI C5 (Cloud Computing Compliance Criteria Catalogue)Not listed
Vendor claimed

Company IR announcement 7 Nov 2023: C5 Type 1 for Compute Engine, Cloud Cubes, S3 Object Storage after external audit. Type 1 = design at a point in time; confirm current validity and product scope.

Considerations & known limitations: Cyso Cloud vs IONOS
Considerations & known limitationsLogo: Cyso CloudCyso CloudLogo: IONOSIONOS
Only two live public regions
Medium

Production public cloud is AMS and FRA today. Multi-continent latency, in-country residency outside NL/DE, or extensive multi-region DR across Europe may require another provider or private cloud.

Not listed
No default object storage encryption at rest
Medium

Official FAQs state no standard server-side encryption at rest; TLS in transit and client-side/SSE-C patterns are recommended. Regulated designs must implement key management outside default storage behaviour.

Not listed
Incomplete public subprocessor inventory
Medium

Primary hosting path is vendor-operated EU hardware, but privacy materials list third parties without a dedicated live subprocessor register for all ancillary processing. Request the schedule under NDA or DPA annex.

Medium

Unlike many pure SaaS vendors, a single customer-facing subprocessor list was not found. Buyers must extract partners from location pages, DPA annexes, and product docs (Equinix, Acronis, Microsoft, Google, etc.).

Certifications are vendor-published PDFs
Low

ISO 27001 and NEN 7510 are claimed with certificate PDFs on Cyso sites; this draft did not independently verify registry entries. Treat as claimed until audit pack is reviewed.

Not listed
Smaller ecosystem than hyperscalers
Low

Fewer managed PaaS services and marketplace options than AWS/Azure/GCP. Expect to run more of the stack yourself on OpenStack/Kubernetes.

Not listed
US regions, US entities, and facility partnersNot listed
Medium

Selecting US locations places data in the US. Even EU-only deployments sit in a group that has US subsidiaries and uses partners such as Equinix for some EU facilities—material for CLOUD Act / transfer reviews.

C5 Type 1 scope and freshnessNot listed
Low

Public C5 claim is Type 1 for specific products (Compute Engine, Cubes, Object Storage) as of the 2023 announcement. Not a blanket certificate for every IONOS product; request up-to-date reports.

Narrower managed ecosystem than hyperscalersNot listed
Low

Strong IaaS and selected PaaS, but not a full AWS/Azure service catalogue. Multi-region global apps and niche managed services may force multi-cloud or a different primary vendor.

Hosting brand vs cloud platform complexityNot listed
Low

SMB hosting contracts, reseller office suites, and enterprise cloud AVVs are different commercial and compliance surfaces—do not assume one DPA covers every SKU.

Fit

Cyso Cloud

Best fit when

  • European product/SaaS teams that need VMs, volumes, and S3-compatible storage with explicit Amsterdam or Frankfurt residency
  • Organisations standardising on OpenStack APIs/CLI to reduce hyperscaler lock-in and support multi-cloud portability
  • Teams wanting CNCF KCSP managed Kubernetes with hibernation and pay-as-you-go worker nodes on EU infrastructure
  • Dutch healthcare-adjacent or regulated buyers who need NEN 7510 alongside ISO 27001 claims from a NL operator
  • Buyers evaluating a private OpenStack cloud or VMware alternative on their own data-centre hardware

Poor fit when

  • Workloads that require many global regions, edge PoPs, or a large marketplace of managed PaaS services
  • Storage designs that assume default server-side encryption at rest without customer-managed keys
  • Procurement that must rely only on a fully published subprocessor schedule without vendor engagement
  • Teams that need fully self-serve free tiers or only automated chat support with no human engineering contact

Consider instead when

  • When: You need many European (or global) regions and a broader product catalogue than two live IaaS regions

    Consider: OVHcloud or Scaleway

    Larger EU multi-region footprints; different APIs and commercial models.

  • When: You want Swiss multi-zone simplicity with strong managed Kubernetes emphasis

    Consider: Exoscale

    Swiss operator profile; fewer regions than hyperscalers but clear sovereignty messaging.

  • When: You need maximum global PaaS depth, AI services, and worldwide edge

    Consider: Amazon Web Services, Microsoft Azure, or Google Cloud Platform

    Trade EU ownership for ecosystem breadth; apply your own residency and CLOUD Act analysis.

  • When: You prioritise high-performance European VMs across more city locations than AMS/FRA only

    Consider: UpCloud

    Different stack; compare residency guarantees and support model side by side.

IONOS

Best fit when

  • SMB and agencies needing domains, hosting, email/office resale, and a personal consultant under one German brand
  • Teams building IaaS workloads in selectable EU locations with a visual Data Center Designer and full Cloud API
  • Organizations that want managed Kubernetes, DBaaS, and S3-compatible storage without a hyperscaler contract
  • DACH public-sector or regulated buyers who need documented BSI C5 / IT-Grundschutz posture on scoped cloud products (confirm current report)
  • AI or inference pilots that prefer vendor-stated Germany (Berlin) hosting for AI Model Hub

Poor fit when

  • Buyers requiring a guarantee of no US legal entities, no US regions, and no US-group facility partners anywhere in the path
  • Workloads that depend on the full AWS/Azure/GCP marketplace, global region density, or niche managed services IONOS does not offer
  • Price-only bare-metal or Hetzner-style DIY shops that do not need managed PaaS or SMB hosting layers
  • Teams that refuse any US-group SaaS (Microsoft 365 / Google Workspace) if those bundles are part of the intended stack

Consider instead when

  • When: You want French-operated cloud with strong developer packaging and EU focus without a mass-market hosting brand

    Consider: Scaleway

    Different product mix; compare region map and managed services side by side.

  • When: You prioritize large European hosting/cloud scale and multi-country DC ownership narratives

    Consider: OVHcloud

    Both are EU groups with non-trivial international footprints—read residency options carefully.

  • When: You mainly need cost-efficient dedicated servers or simple cloud in DE/FI with minimal PaaS

    Consider: Hetzner

    Thinner managed layer; different support and SMB hosting model.

  • When: You are already in Schwarz Group ecosystems or need STACKIT-specific public-cloud positioning

    Consider: STACKIT

    Narrower commercial brand than IONOS hosting+cloud combo.

Open questions for due diligence

Cyso Cloud

  • Can Cyso provide the current DPA, technical and organisational measures, and a dated subprocessor list covering payments, support, analytics, and status tooling?
  • What is the exact OpenStack release, upgrade cadence, and any divergences from upstream APIs that affect Terraform/automation?
  • For object storage and volumes, what encryption-at-rest or KMS options can be contractually committed for regulated data?
  • What are contractual 24/7 escalation SLAs for severity-1 incidents beyond office-hours tech-to-tech support?
  • Which additional EU regions (if any) have committed go-live dates versus community voting only?

IONOS

  • What is the current BSI C5 report type (Type 1 vs Type 2), validity period, and exact product/location scope?
  • Can IONOS provide a consolidated subprocessor and sub-processor change-notification list under the DPA/AVV?
  • Which contract entity (IONOS SE vs IONOS Cloud GmbH vs national affiliates) will sign for our workload and which TOMs apply?
  • For EU-only deployments, are any support, monitoring, or backup control-plane components processed outside the EU?
  • Is ISO 27001 held by IONOS operating companies for the full service stack, or primarily facility/operator certifications?
