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.

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.

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.

Assurance & compliance: Cyso Cloud vs Leaseweb
Assurance & complianceLogo: Cyso CloudCyso CloudLogo: LeasewebLeaseweb
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.

Not found

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

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: 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.

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.

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.

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

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

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

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.

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

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).

NEN 7510 (Dutch healthcare information security)
Vendor claimed

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

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.

EU AI Act
Not applicable

IaaS/infrastructure platform, not an AI system product.

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.

PCI DSSNot listed
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.

CISPE IaaS Code of ConductNot listed
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.

Considerations & known limitations: Cyso Cloud vs Leaseweb
Considerations & known limitationsLogo: Cyso CloudCyso CloudLogo: LeasewebLeaseweb
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.

Not listed
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
Global catalog includes US halls and a US affiliateNot listed
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.

No public IaaS subprocessor registerNot listed
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).

Certification scope is entity- and service-specificNot listed
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.

Public Cloud / VPS IPv4 and Elastic Compute end of saleNot listed
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.

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.

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 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?

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?
