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 must browser-enable an existing Java Swing/JavaFX/SWT/NetBeans or Oracle Forms estate without a rewrite and can run a self-hosted session tier. Skip when you are building a greenfield web UI only, or when the app depends on video, 3D acceleration, or ultra-low-latency graphics. Consider Citrix/VDI or a hyperscaler cloud desktop when you need generic desktop remoting beyond Java UI toolkits.

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.

Webswing

  • Browser delivery without rewriting Java UI

    Runs Swing, JavaFX, SWT, NetBeans Platform, Applets, and Oracle Forms in HTML5 browsers over WebSockets with no required source changes. End users need a browser only, not a local JRE or plugin.

  • Customer-controlled self-hosted runtime

    Install from a distribution ZIP or containers on your own servers, VMs, Docker, or Kubernetes. Standalone and Cluster Engine modes cover single-node pilots through multi-node scale-out with admin monitoring.

  • Incremental modernisation beside legacy screens

    Modernisation Framework and JsLink let React, Angular, Vue, Vaadin, or APEX components coexist with Java UI so teams can rewrite modules over time instead of a big-bang cutover.

  • Enterprise auth and session operations

    Pluggable security modules include SAML2, OpenID Connect, Keycloak, LDAP, and custom providers. Admin Console adds session mirror view, recording/playback, logs, and multi-tenant path isolation.

  • Built-in printing, files, and clipboard bridges

    Browser-side printing with preview, isolated upload/download folders, and clipboard integration cover common desktop workflows that break in naive remote-app setups.

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.

On request / NDA

Footer states regular security testing is available upon request; no public independent audit PDF found.

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

Site footer: Webswing Limited maintains an ISO/IEC 27001-certified ISMS. Independent cert registry entry not verified in this pass.

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.

Not found

No SOC 2/3 claim found on public site pages reviewed.

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

Privacy policy names WEBSWING LIMITED as Irish controller under GDPR; FAQ states GDPR alignment for company contact data.

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

EU entity with no known US parent; self-hosted runtime keeps sessions on customer infra. Vendor website/portal lists US-group processor The Rocket Science Group LLC (email) plus Google/Meta/LinkedIn Ireland entities for analytics/ads. 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).

Not found

Privacy policy references Art. 28 DPAs with Webswing's own processors; no public customer-facing DPA download found. Request during procurement.

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.

Not applicable

Core product is application delivery/runtime, not an AI system. Prague research affiliate explores AI; not the catalogued product.

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.

Nicht angegeben

Considerations & known limitations: Leaseweb vs Webswing
Considerations & known limitationsLogo: LeasewebLeasewebLogo: WebswingWebswing
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.

Nicht angegeben
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).

Nicht angegeben
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.

Nicht angegeben
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.

Nicht angegeben
Higher per-session server resourcesNicht angegeben
Medium

Docs state each browser session needs more server CPU/memory than a native web app. Capacity planning and Cluster Engine matter for large concurrent user counts.

Video, 3D, and low-latency limitsNicht angegeben
Medium

Official overview: video not supported, limited sound, no 3D hardware acceleration, poor fit for real-time action games due to rendering latency.

Proprietary licensing since 21.1Nicht angegeben
Low

Current releases require commercial license + SLA. AGPL/public source stopped after 20.2. Source access for licensed customers is via Client Portal rather than a public repo.

Vendor portal/marketing US-group processorsNicht angegeben
Low

Privacy policy lists The Rocket Science Group LLC and major ad/analytics vendors for website/portal data. Irrelevant to on-prem session pixels, but relevant if you put sensitive personal data only into vendor portals.

ISO 27001 not independently verified hereNicht angegeben
Low

Vendor claims ISO/IEC 27001-certified ISMS on the site footer. Ask for the current certificate and scope before treating it as verified.

Passung

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).

Webswing

Best fit when

  • Enterprises and ISVs with production Swing, JavaFX, SWT, NetBeans, or Oracle Forms applications that must become browser-accessible without a rewrite
  • Teams that can operate a self-hosted Webswing tier (on-prem, VM, Docker, or Kubernetes) and size CPU/memory per concurrent session
  • Organisations planning incremental UI modernisation (React/Angular/Vue/APEX) while keeping proven Java screens online
  • Buyers who want Irish/EU contracting (WEBSWING LIMITED) and customer-controlled residency for application sessions
  • Public-sector or regulated estates retiring endpoint Java installs or reducing Citrix/VDI dependency for Forms/Swing only

Poor fit when

  • Greenfield products with no existing Java desktop or Forms UI to preserve
  • Multimedia, video, 3D-accelerated, or real-time action-game style interfaces (documented limitations)
  • Teams unwilling to run and scale a server-side session farm for interactive users
  • Buyers who require OSI-approved open source for the current release line (proprietary since 21.1)

Consider instead when

  • When: You need generic Windows/Linux desktop remoting rather than Java UI toolkit remoting

    Consider: Citrix / enterprise VDI, or Microsoft Azure Virtual Desktop

    Webswing FAQ positions itself as a narrower alternative to Citrix for Forms/Java estates.

  • When: You are rewriting the UI entirely and have no need to keep Swing/Forms screens running

    Consider: Native web frameworks (React, Angular, Vue) or Oracle APEX without a Webswing bridge

    Webswing's Modernisation Framework is for coexistence during migration, not a mandatory layer for new UIs.

  • When: You want a hyperscaler-managed browser app streaming control plane

    Consider: AWS AppStream / WorkSpaces-class services or Azure cloud desktop offerings

    Trade self-hosted EU software control for managed cloud operations.

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?

Webswing

  • Will Webswing provide the current ISO 27001 certificate PDF and statement of applicability scope?
  • Is a customer DPA available for Client Portal / support data processing, and which subprocessors apply to licensed customers?
  • Where is portal.webswing.org physically hosted, and are any non-EU regions used for backups?
  • For your Forms/Swing edge cases (WebUtil, local devices, printers), which patterns are supported without code changes?
