Needs review

Shortlist IONOS when you want a German-operated hosting + public cloud stack with EU location choice, managed Kubernetes, S3 storage, and public BSI-oriented cloud certifications for DACH buyers. Skip when you need hyperscaler service breadth, EU-only infrastructure with no US regions or US facility partners in the path, or lowest-cost bare metal—consider OVHcloud, Scaleway, Hetzner, or STACKIT instead depending on that gap.

gridscale

  • Panel + API + Terraform provisioning

    Deploy VMs with attached storage in seconds via the control panel or automate with the REST API and common IaC clients (Terraform, Packer). Built for teams that want both click-ops and git-ops without a hyperscaler control-plane learning curve.

  • Managed Kubernetes, databases, and load balancers

    PaaS layers cover managed Kubernetes orchestration plus fully managed databases with audit logs and automatic backups, and managed load balancers for traffic distribution—so app teams avoid running the full stack themselves.

  • S3-compatible object storage and Rocket NVMe storage

    Object storage follows S3-style APIs for backups, archives, and unstructured data, with region choice called out for GDPR-oriented placement. Rocket Storage targets high-IOPS NVMe workloads; not every Hybrid Core location exposes object storage—check the data-center matrix.

  • Per-minute GPU bare-metal for AI/ML

    GPU instances are marketed as dedicated bare-metal performance for AI/ML and data science, with CPU, RAM, and storage included and usage billed by the minute rather than only long-term reserved shapes.

  • Hybrid Core Concierge HCI and white-label cloud

    Fully managed hyperconverged packages combine hardware delivery, installation, remote operations, white-label branding/SAML options, and access to the wider gridscale location ecosystem—aimed at enterprises and hosters building private or partner clouds.

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: gridscale vs IONOS
Assurance & complianceLogo: gridscalegridscaleLogo: IONOSIONOS
Independent security / no-logs audit
Not applicable

IaaS/PaaS provider—not a no-logs VPN product. Request penetration-test or SOC-style reports under NDA if required.

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 compliance pages and chronology claim ISO/IEC 27001; obtain current certificate for verification.

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.

ISO 27017 (cloud security)
Vendor claimed

Compliance page links a certificate PDF download; treat as vendor-published evidence until auditor validates.

Not listed
ISO 27018 (cloud PII)
Vendor claimed

Claimed on compliance/about materials; request current scope.

Not listed
SOC 2 / SOC 3
Not found

No public SOC 2 found; vendor promotes ISAE 3402 SOC 1 Type 2 instead (different standard).

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.

ISAE 3402 SOC 1 Type 2
Vendor claimed

About chronology highlights successful ISAE 3402 SOC 1 Type 2 (incl. January 2025 call-out). Request full report.

Not listed
BSI C5
Vendor claimed

Prominently listed on compliance pages; About chronology pairs C5 with January 2025 certification success. Request current attestation.

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.

GDPR / EU data protection
Vendor claimed

German controller (gridscale GmbH); European location marketing; privacy policy under DS-GVO. Confirm DPA and location selection for your processing.

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

EU entity, no known US parent (OVHcloud France owns group). Customer hosting marketed in EU/CH/AT. Partial because privacy recipient list includes US-group Stripe, Google Analytics/GTM, Microsoft, Meta, LinkedIn for payments/marketing. 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

GTC §14.2 requires a separate order-processing contract when gridscale processes personal data for the customer, finalised at latest on contract conclusion. Execute AV/DPA—do not rely on website privacy alone.

Vendor claimed

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

EU AI Act
Not applicable

Infrastructure cloud; not an AI system product. GPU capacity may host customer AI workloads under shared-responsibility model.

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.

Trusted Cloud (DE)
Vendor claimed

Compliance page links Trusted Cloud service listing; verify current entry on trusted-cloud.de.

Considerations & known limitations: gridscale vs IONOS
Considerations & known limitationsLogo: gridscalegridscaleLogo: IONOSIONOS
Parent-group integration after OVHcloud acquisition
Medium

100% OVHcloud ownership since 2023 may change roadmap, tooling, support model, or cross-entity data flows over time. Confirm entity, subcontractors, and exit terms for your contract generation.

Not listed
Partner-operated Hybrid Core locations
Medium

Some sites are operated with partners (hosttech, rhöncloud, BAIONITY, windCORES, etc.). Capability matrices differ (for example object storage not everywhere). Map exact location codes to SLA and subprocessor wording.

Not listed
US-group ancillary processors (account/marketing)
Medium

Privacy policy lists Stripe, Google Analytics/GTM, Microsoft Bing Ads, Meta, and LinkedIn. Material for DPIAs even when VM disks stay in EU halls. Ask which tools touch production account identities versus marketing only.

Not listed
Certifications need current attestation packs
Low

BSI C5, ISAE 3402, and ISO claims are vendor-published. Production security reviews should obtain dated reports rather than relying on marketing badges alone.

Not listed
Narrower global footprint than hyperscalers
Low

Location set is European-weighted. Unsuitable as a drop-in for multi-continent latency or hyperscaler-only services (global CDN marketplaces, specialized managed services).

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.

No clear public subprocessor catalogueNot listed
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.).

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

gridscale

Best fit when

  • DACH mid-market teams wanting German contracting plus managed PaaS (Kubernetes, databases, load balancers)
  • MSPs and hosters needing white-label branding, multi-tenant accounts, and optional Hybrid Core hardware
  • Workloads that must pick DE/NL/CH/AT regions with Tier 3 marketing claims and green-energy positioning
  • AI/ML or data-science jobs that need GPU bare-metal with per-minute metering
  • Buyers who value panel + API/Terraform over hyperscaler IAM sprawl

Poor fit when

  • Global multi-region applications that need hyperscaler edge, marketplace services, or non-European regions
  • Teams optimising only for lowest bare VM or dedicated-server unit cost (evaluate Hetzner first)
  • Buyers requiring public SOC 2 Type II specifically rather than ISAE 3402 SOC 1 Type 2 / BSI C5 packs
  • Organisations that forbid any US-group ancillary processors (Stripe/Google marketing tools appear in the privacy recipient list)

Consider instead when

  • When: You need the broader European hyperscale portfolio and more regions under one group brand

    Consider: OVHcloud

    OVHcloud is the parent group; gridscale stays the HCI/panel-focused product line

  • When: Cost-sensitive VMs or dedicated servers dominate and you do not need Hybrid Core white-label

    Consider: Hetzner

    Hetzner typically wins raw price/performance for simple compute

  • When: France-centric developer cloud with different location and product skew

    Consider: Scaleway

    Compare ARM options and FR footprint versus gridscale DACH Hybrid Core

  • When: Swiss-rooted EU cloud positioning is the primary evaluation criterion

    Consider: Exoscale

    Still compare DE/CH site maps and managed service depth side by side

  • When: You need worldwide regions, marketplace depth, or US-public-sector cloud programmes

    Consider: Amazon Web Services (AWS) or Microsoft Azure

    Trade EU-entity simplicity for hyperscaler breadth and US ownership path

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

gridscale

  • Will gridscale execute your template AV/DPA and attach a location-specific subprocessor list for the regions you enable?
  • What is the current scope and report date for BSI C5 and ISAE 3402 SOC 1 Type 2 covering the services you will buy?
  • Which privacy-policy third parties process production account/identity data versus website marketing only?
  • How are OVHcloud group affiliates involved in support, billing, or platform operations for gridscale customers post-acquisition?
  • For Hybrid Core partner sites, who is the data-center operator of record and what audit rights apply?

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?
