Needs review

Shortlist when you want a Dutch (or other local Leaseweb) B2B contract for dedicated servers, CloudStack public cloud, colo, or regional object storage, and you will pick the DC yourself. Skip when you need EU-only halls with no US affiliate in the group, a hyperscaler-width managed-platform catalog, or self-serve hobby VPS without KYC. Consider Hetzner or OVHcloud for simpler EU-centric IaaS, or AWS if you need the global managed-service surface.

Needs review

Shortlist when you need a German Telekom/T-Systems OpenStack public cloud with DE/NL/CH regions and a strong BSI C5/ISO/TISAX package for regulated or public-sector workloads. Skip when you need hyperscaler global PaaS breadth or pure self-hosted OpenStack—consider OVHcloud, Scaleway, or AWS/Azure for those cases.

Leaseweb

  • Dedicated servers with portal, API, and Instant Delivery

    Bare metal for databases, analytics, gaming, and e-commerce. The knowledge base lists Windows or Linux images, Volume or Premium transit, interconnects, and Layer 2 private networking. First orders are phone-verified. Instant Delivery SKUs can provision within an hour; custom builds take longer. CPU cannot be upgraded in place.

  • CloudStack Public Cloud on KVM

    Instances run on Leaseweb-owned CloudStack KVM with general-purpose, compute, memory, and GPU-oriented families. Billing is hourly on-demand or monthly. Local NVMe is faster but slower to recover if a hypervisor fails. Central NFS storage is the higher-availability path. Each instance gets one public IPv4. Extra IPv4 is not offered yet.

  • S3-compatible object storage with named regions

    HTTPS/S3 API buckets at nl.object-storage.io, de.object-storage.io, uk.object-storage.io, us.object-storage.io, ca.object-storage.io, and sg.object-storage.io. Leaseweb says objects are stored in three availability zones. The default S3 region name us-east-1 is a compatibility alias, not a geography. Keys are created in the Customer Portal.

  • Colocation with remote hands

    Bring your own servers into Leaseweb halls. Shared 1U to 5U is only in AMS-01 and FR-01. Private racks and cages are for larger or more isolated deployments. Remote hands are 24/7 and included by default, with higher packages available. Colo knowledge base counts six European halls (Netherlands, Germany, UK), seven in Asia-Pacific and Oceania, and twelve in the US and Canada.

  • Private network and Cloud Connect to hyperscalers

    Layer 2 private networking can join dedicated servers, Public Cloud, VMware products, and colo in the same DC (and some metro pairs). Cloud Connect uses Megaport SDN plus a Leaseweb router to reach AWS, Google Cloud, and Azure from selected halls (including AMS-01/02, FRA, London, WDC-02, Singapore, Montreal, Sydney). Redundant paths are Active-Standby. Delivery is quoted in business days via sales.

  • Customer Portal, REST API, and Terraform

    Operators power-cycle, reinstall, rescue, manage IPs, attach private networks, and watch traffic graphs without a ticket for routine work. developer.leaseweb.com documents the REST API, GitHub integrations, a Terraform provider for Leaseweb Cloud, and S3 compatibility. This is not a self-hosted control plane you run yourself.

Open Telekom Cloud

  • OpenStack public cloud with Elastic Cloud Server and GPUs

    Self-service IaaS on OpenStack: Elastic Cloud Server flavors from general-purpose to GPU shapes for AI/ML and graphics, plus Dedicated Host and Bare Metal where the region supports them. Provision via console, API, or automation; Auto Scaling for metric-driven capacity. Suited to production VMs and hybrid patterns that need European operator control rather than a thin VPS plan.

  • Multi-AZ object, block, and file storage in EU regions

    Object Storage Service provides S3-compatible multi-AZ object storage; Elastic Volume Service attaches block disks with snapshots; Scalable File Service offers NFS shared filesystems. Cloud Backup and Recovery and related services back up VMs and volumes into platform object storage. Pin workloads to DE, NL, or Swiss regions according to residency policy.

  • VPC networking, Direct Connect, and security services

    Virtual Private Cloud isolation, Elastic Load Balancer, VPN, NAT, Enterprise Router, and Direct Connect for high-bandwidth hybrid links. Security stack includes Anti-DDoS, WAF, Cloud Firewall, Host Security Service, and Key Management Service with bring-your-own-key options—useful for regulated network architectures without leaving Telekom-operated regions.

  • Cloud Container Engine and managed data services

    Cloud Container Engine runs Kubernetes-managed clusters and images; companion services cover container instances and registries. Relational Database Service supports MySQL, PostgreSQL, and Microsoft SQL with HA and backup patterns; document, cache (Redis-class), MapReduce, and search services extend the data plane. Service availability differs between DE and NL—check the regional matrix before design freezes.

  • ModelArts and sovereign AI positioning

    ModelArts provides an end-to-end AI development path (data prep, training, deployment) on European infrastructure, with GPU-backed instances for training and inference. Aimed at teams that want model and training-data residency under the same European operator as their IaaS—confirm which AI services exist in your chosen region (several AI offerings are DE-focused).

  • Twin-core European data centers (DE, NL, CH)

    Published regions: twin-core Germany (Biere/Magdeburg), Netherlands (Amsterdam area), and Switzerland (Bern/Zollikofen) for Swiss data residency. Vendor claims geo-redundant twin-core design, high availability targets, and renewable-powered German facilities. Not a global multi-continent footprint—by design for European sovereignty shortlists.

Assurance & compliance: Leaseweb vs Open Telekom Cloud
Assurance & complianceLogo: LeasewebLeasewebLogo: Open Telekom CloudOpen Telekom Cloud
Independent security / no-logs audit
Not found

IaaS provider, not a no-logs VPN. No public independent audit of logging practices found beyond the named ISO/SOC/PCI reports.

Not applicable

IaaS platform—not a no-logs consumer VPN. Independent assurance is via ISO/SOC/C5-style audits rather than a no-logs report.

ISO 27001
Vendor claimed

Vendor: ISO 27001:2022 via EY CertifyPoint for Leaseweb Global B.V., Netherlands B.V., USA, Deutschland, UK, Singapore, Canada, Network B.V. Services listed: corporate infrastructure, bare metal, VPS, private/hybrid cloud, colo, web hosting, domains. Certificate download promised on the marketing security page (SPA). Independent register entry not retrieved in this pass.

Vendor claimed

Vendor certifications page links ISO/IEC 27001 umbrella certificate PDF for download; re-verify serial/date in procurement.

SOC 2 / SOC 3
Partial

SOC 2 published for Leaseweb Canada, Inc. colocation (Security and Availability, UHY Forbes Andersen). Several entities have SOC 1 Type II (EY / ISAE 3402) covering cloud, dedicated, colo, and web hosting.

Vendor claimed

SOC 2 Type II (request report); SOC 3 public PDF linked on certifications page. SOC 1 Type II also claimed.

GDPR / EU data protection
Vendor claimed

NL entity; Clause 8 cites GDPR and the Dutch UAVG. Transfers outside the EEA only with safeguards. Global catalog still includes non-EU regions.

Vendor claimed

EU operator, EU/CH regions, ISO 27018/27701 claims, DPA language on marketing pages—confirm signed DPA for your entity.

US CLOUD Act exposure (indicative)
Partial

Dutch group, no known US parent, but the catalog includes US halls, Leaseweb USA, Inc., us-01 object storage, and optional Cloud Connect to AWS/GCP/Azure. NL Clause 8.3 can keep a Netherlands contract on Dutch DCs if you do not choose otherwise. Assessment row, not a vendor claim. Not legal advice.

Partial

German Telekom/T-Systems operator, no known US parent of the cloud business, primary hosting on Telekom EU/CH data centers (not AWS/GCP/Azure). Not a legal clearance of zero extraterritorial risk. Historical Huawei tech partnership is separate supply-chain diligence. Not legal advice.

Data processing agreement (B2B)
Vendor claimed

Privacy page (search snippet) and NL/DE sales terms: processor language in Clause 8; standalone DPA on request in older DE terms. Sub-processor list on request (NL 8.4).

Vendor claimed

Vendor GDPR pages state DPA, TOMs, and audit reports available for B2B; obtain current signed pack—not fully self-serve public template verified here.

EU AI Act
Not applicable

IaaS compute, storage, colo, and network. Public Cloud lists small-scale GPU/inference instance types, but the offering is not an AI system product.

Partial

Platform offers AI services (ModelArts) that may fall under customer AI Act obligations; OTC itself is infrastructure—not an automated high-risk AI system assessment by EuropeanStack.

PCI DSS
Partial

Vendor: PCI DSS 4.0 scoped to physical security at named DCs (AMS-01, FRA-01, LON-01, SIN-01, WDC-02, MTL-01/02/03). Services are not meant to process card data by default.

Not listed
NEN 7510
Vendor claimed

Vendor: EY statement for Leaseweb Netherlands B.V. at AMS-01 (physical security, IS policy, risk, resilience, incidents, service deployment). Not inherited by the customer.

Not listed
CISPE IaaS Code of Conduct
Vendor claimed

Historical CISPE member listing and lobbyfacts affiliation. Current CISPE public register was not confirmed to contain a live Leaseweb service declaration in this pass.

Not listed
ISO/IEC 27017 (cloud security)Not listed
Vendor claimed

Claimed with downloadable attestation PDF on certifications page.

ISO/IEC 27018 (cloud PII)Not listed
Vendor claimed

Claimed with downloadable attestation PDF on certifications page.

BSI C5 Type IINot listed
Vendor claimed

Vendor claims BSI C5:2020 Type II (ISAE 3000); detailed report typically on request via audit-reports download flow.

TISAX Level 3Not listed
Vendor claimed

Vendor states TISAX Level 3 for Germany and Netherlands regions.

Considerations & known limitations: Leaseweb vs Open Telekom Cloud
Considerations & known limitationsLogo: LeasewebLeasewebLogo: Open Telekom CloudOpen Telekom Cloud
Global catalog includes US halls and a US affiliate
Medium

Even with a Dutch contractor and NL Clause 8.3, the product menu includes US dedicated halls, us-01 object storage, and Leaseweb USA, Inc. Buyers with a residency ban must lock region and entity in the order, not rely on the brand name.

Not listed
No public IaaS subprocessor register
Medium

NL terms authorise EEA affiliates and other third parties as sub-processors, with the actual list on request. Known optional paths: Megaport plus AWS/GCP/Azure (Cloud Connect) and Acronis (Public Cloud backup row). Website marketing also uses US SaaS (outside the IaaS path).

Not listed
Certification scope is entity- and service-specific
Low

ISO is claimed for listed IaaS services, not automatically for every SKU. SOC 2 is Canada colo. PCI is physical security only. Customers are not certified by association.

Not listed
Public Cloud / VPS IPv4 and Elastic Compute end of sale
Low

Docs: one public IPv4 on Public Cloud and VPS, extras not yet available. Elastic Compute is end of sale. Dedicated CPU cannot be upgraded without a new server.

Not listed
Historical Huawei technology partnershipNot listed
Medium

Platform launched with Huawei hardware/software partnership; residual stack components may still matter for sensitive public-sector RFPs. T-Systems states independent operation. Review supply-chain docs under NDA.

Service catalog differs by regionNot listed
Medium

Several services (e.g. ModelArts, bare metal, some database/analytics SKUs) are unavailable in NL or limited to DE. Design against the live regional matrix, not the full marketing list.

Limited public subprocessor tableNot listed
Low

Unlike some SaaS vendors, a complete public subprocessor inventory was not found on marketing pages. Request DPA annex and subcontractor list before high-assurance processing.

Smaller global ecosystem than AWS/Azure/GCPNot listed
Low

Expect fewer regions, fewer proprietary PaaS services, and a smaller marketplace than US hyperscalers. Migration tools and partner ecosystem exist but differ in depth.

Brand transition OTC → T Cloud PublicNot listed
Low

Documentation, console URLs, and community still mix Open Telekom Cloud and T Cloud Public names. Factor rebrand into runbooks and vendor risk registers.

Fit

Leaseweb

Best fit when

  • Teams that want a KvK-identifiable Dutch contractor (Leaseweb Netherlands B.V.) for IaaS, not a US parent
  • Operators placing dedicated servers or colo in named halls (Amsterdam, Frankfurt, London, plus optional non-EU cities)
  • Workloads that need CloudStack KVM or S3-compatible buckets with an explicit nl-01 / de-01 / uk-01 endpoint
  • Hybrid designs that keep origin on Leaseweb metal and optionally Cloud-Connect to AWS, Google Cloud, or Azure
  • Buyers who will use the Customer Portal, REST API, or Terraform rather than a fully managed PaaS

Poor fit when

  • Organisations that forbid any US group company, US datacentre option, or US-region object storage in the same vendor catalog
  • Teams that need extra public IPv4 on Public Cloud or VPS (docs: one IPv4, extras not yet available)
  • Buyers looking for a self-hosted control plane or an open-source product they operate themselves
  • People who actually wanted Leaseweb Multi-CDN rather than compute and colo
  • Hobby or consumer hosting: NL terms state B2B only, with KYC on first order

Consider instead when

  • When: You want a larger managed-cloud catalog (IAM, managed databases, serverless) and accept a US parent

    Consider: Amazon Web Services (AWS) or Google Cloud Platform

    Different jurisdiction and product surface. Leaseweb stays IaaS-classic.

  • When: You want European IaaS with a simpler EU-centric hall list and strong self-serve dedicated servers

    Consider: Hetzner or OVHcloud

    Still diligence their own non-EU options. Neither is a Leaseweb contract.

  • When: You want French public cloud with object storage and more developer-cloud SKUs

    Consider: Scaleway

    Different product mix. Confirm current regions on Scaleway's site.

  • When: You mainly need a German-group host with a broad SMB catalog

    Consider: IONOS

    Different ownership and SKU mix than Leaseweb's local-entity IaaS model.

  • When: You actually needed global content delivery, not origin compute

    Consider: Leaseweb CDN

    Same group, different data path (partner CDNs and a Washington D.C. shield).

Open Telekom Cloud

Best fit when

  • German public sector and regulated buyers needing Telekom-group operator plus BSI C5 / ISO package
  • Enterprises pinning workloads to DE, NL, or Swiss twin-core regions under GDPR (and Swiss DSG where relevant)
  • Teams wanting OpenStack-based IaaS with ECS, object/block storage, VPC, and Kubernetes (CCE) without US hyperscaler residency defaults
  • AI/ML projects that require GPU capacity and ModelArts-class tooling with European data residency messaging
  • Hybrid architectures using Direct Connect / VPN into Telekom data centers with 24/7 European support expectations

Poor fit when

  • Workloads that require dozens of global regions or deep proprietary hyperscaler PaaS catalogs
  • Buyers seeking a free self-hosted OpenStack distribution rather than a commercial public cloud
  • Teams that need every service in every region—several AI, bare-metal, and data services are DE-only or limited
  • Organisations that reject any non-European technology supply chain without further review (historical Huawei partnership)

Consider instead when

  • When: You need extensive bare-metal catalogs and a very large multi-country EU footprint

    Consider: OVHcloud

    Different operator (France) and product packaging; compare bare-metal and region maps.

  • When: You prefer developer-centric European cloud packaging outside the Telekom stack

    Consider: Scaleway or Exoscale

    Scaleway for FR/NL-oriented developer UX; Exoscale for Swiss multi-zone IaaS + managed K8s.

  • When: You need global regions, marketplace depth, or proprietary PaaS only hyperscalers provide

    Consider: AWS, Microsoft Azure, or Google Cloud Platform

    Accept US-parent CLOUD Act exposure and multi-region complexity in exchange for breadth.

  • When: You want German-market hosting adjacency with a different commercial/product mix

    Consider: IONOS

    Often compared for German buyers; validate IaaS depth vs OTC enterprise cloud features.

Open questions for due diligence

Leaseweb

  • For the SKUs we will buy, what is the current ISO 27001 statement of applicability (and is object storage in scope)?
  • Will Leaseweb issue the current sub-processor list for this order, including Acronis and Megaport if used?
  • Can the contract freeze region to named EU halls and forbid US-affiliate access except as Clause 8.3 allows?
  • What is the current Instant Delivery dedicated inventory in AMS/FRA versus US halls?
  • Is there a live CISPE public-register declaration for these IaaS services?

Open Telekom Cloud

  • Will T-Systems provide the current full subprocessor/subcontractor list and signed DPA annex for our legal entity and region?
  • What is the residual Huawei (or other non-EU) component inventory for the regions we will use, and is it acceptable under our procurement policy?
  • Which services in our target architecture are available in DE vs NL vs Swiss regions with which SLAs?
  • Can we obtain current C5 Type II and SOC 2 reports (not only marketing claims and SOC 3 summary) under NDA?
  • For AI workloads, which ModelArts/GPU SKUs and data paths apply, and how do they map to our EU AI Act role?
