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.

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.

Seeweb

  • KVM Cloud Servers with dedicated resources

    Cloud Server is a KVM virtual machine with dedicated CPU, RAM, and SAN-backed storage, N+1 style redundancy messaging, and guaranteed 1 Gbps bandwidth class. Scale vertically (add CPU/RAM/disk) or horizontally by composing multi-tier stacks. Unmanaged or fully managed by Seeweb engineers—fit for production web, DB, and agency workloads that need predictable isolation rather than noisy shared hosts.

  • GPU cloud for AI/ML (NVIDIA + AMD)

    Cloud Server GPU instances target training, inference, and HPC-style jobs with NVIDIA cards (H100, H200, A100, L40S, RTX A6000, L4 and related) and AMD options including MI300X. Ready-to-use drivers, Terraform support, hourly usage billing, and Spot Instances with a short preemption notice suit bursty or interruptible jobs. Data stays on European sites per vendor GDPR messaging—confirm region per SKU at order time.

  • Managed Kubernetes Service (SKS)

    SKS is Kubernetes-as-a-Service with a HA control plane, worker sizing you design with Seeweb, CSI storage (Vast Data driver on the product page), optional S3-compatible object storage, load balancing, and GPU workers (including MI300X and NVIDIA H-class cards). Aimed at teams that want orchestration without running etcd themselves; Proactive Support tiers add predictive monitoring for production clusters.

  • VPC, Foundation Server, and hybrid DC footprint

    Virtual Private Cloud builds private infrastructures on VMware or Proxmox; Foundation Server targets dedicated bare-metal-style capacity for business-critical virtualization. Combine with housing/colocation in Milan and Frosinone plus European partner sites for DR. Useful when you need private networking and dedicated hosts under the same Italian operator rather than public multi-tenant only.

  • ACN-qualified IaaS and CISPE EU residency claims

    Seeweb publishes ACN CSP qualification (QI2 infrastructure; QC2 for Foundation Server Pro, VPC, Shared CPU/High Memory cloud, and AI/supercomputing infrastructures) for Italian public administration procurement. CISPE Code of Conduct registration is used to assert customer data stored exclusively in European territories. Pair these claims with your own DPIA—they are procurement signals, not a substitute for a signed DPA.

Assurance & compliance: Leaseweb vs Seeweb
Assurance & complianceLogo: LeasewebLeasewebLogo: SeewebSeeweb
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/data-center provider—not a consumer no-logs VPN. Assurance is via ISO/ISMS and sector qualifications 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.

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

Italian controller/processor entity, European hosting messaging, privacy policy, ISO 27018 claim, CISPE; confirm DPA for your processing roles.

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

Italian Seeweb S.r.l., Italian DHH parent, no known US parent; primary hosting on European DCs (not AWS/GCP/Azure). Third-party Swiss/BG facilities and global transit carriers exist. Indicative only—not legal advice.

Considerations & known limitations: Leaseweb vs Seeweb
Considerations & known limitationsLogo: LeasewebLeasewebLogo: SeewebSeeweb
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
Smaller global footprint than hyperscalersNot listed
Medium

Region set is European (IT/CH/BG) with a mid-size operator catalog. Multi-continent apps or niche managed PaaS may force multi-cloud or a larger EU peer.

Certifications are vendor-publishedNot listed
Low

ISO and ACN claims include certificate numbers and dates on seeweb.it, but EuropeanStack did not re-download every registry PDF. Re-verify serials and scope statements in formal assurance reviews.

No single public subprocessor register foundNot listed
Medium

Facility partners and network carriers are described on DC pages, but a consolidated customer-content subprocessor list was not found as one public document. Request annex under NDA for regulated workloads.

GPU Spot Instances can be interruptedNot listed
Low

Vendor documents ~2-minute notice before Spot termination when On-Demand needs capacity. Architect batch/checkpointing; do not run sole critical control planes only on Spot.

Some sites use third-party data centersNot listed
Low

Lugano, Zurich, and Sofia are presented via partner facilities (Swisscom, Global Data Centers Switzerland AG, Evolink). Italy-only residency must be contracted explicitly if required.

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).

Seeweb

Best fit when

  • Italian PA and public-sector projects that need ACN-qualified IaaS (verify QI2/QC2 scope against the tender)
  • AI/ML teams wanting European GPU hours (NVIDIA H-class / L-class and AMD MI300X) with usage-based or Spot billing
  • System integrators and SaaS vendors that prefer managed Kubernetes (SKS) plus Italian engineering support over pure DIY clusters
  • Workloads that must stay under Italian/EU legal entities with CISPE-style European data-location claims
  • Hybrid designs combining Cloud Servers or VPC with colocation in Milan/Frosinone and European DR sites

Poor fit when

  • Applications that depend on dozens of global regions or proprietary hyperscaler PaaS (Lambda-style, global managed DB fleets)
  • Buyers seeking a free tier or purely self-hosted open-source cloud distribution without a commercial operator
  • Teams that need a published SOC 2 Type II report as a hard gate (not found on Seeweb certifications page)
  • Organizations that refuse any third-party facility (Swiss/Bulgarian partner DCs) without Italy-only contractual pins

Consider instead when

  • When: You need a large multi-country European cloud with denser product catalog and strong self-service DX

    Consider: OVHcloud or Scaleway

    Broader regions and developer tooling; less Italian ACN-specific packaging than Seeweb.

  • When: You want another Italian sovereign cloud with mass-market public-cloud SKUs

    Consider: Aruba Cloud

    Closest national peer; compare GPU/K8s maturity and PA qualification details side by side.

  • When: You mainly need simple self-service VMs/storage at aggressive commercial terms without Italian PA focus

    Consider: Hetzner

    Strong for general-purpose EU VMs; different compliance and support model.

  • When: You require global enterprise PaaS and marketplace ecosystems

    Consider: AWS or Microsoft Azure

    Accept US-group cloud and CLOUD Act exposure tradeoffs for breadth.

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?

Seeweb

  • Will Seeweb provide a current signed DPA, TOMs, and full subprocessor list scoped to our SKUs and regions?
  • Can every required product (GPU, SKS, VPC) be pinned exclusively to Milan/Frosinone under contract?
  • What is the exact SLA and support tier mapping for our architecture (marketing cites up to 99.99%)?
  • Are current ISO certificate serials and ACN register entries still valid for the products we will buy?
  • Is IBM Spectrum Protect operated entirely on Seeweb infrastructure, or does any backup path leave European facilities?
