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.

Unomed Cloud PACS

Switzerland· Cloud Computing

Needs review

Shortlist for Swiss practices that want a cloud DICOM archive, browser viewing and referrer sharing without replacing their PIS, and that accept a Zurich SaaS vendor with claimed Swiss image hosting. Skip when you need a default CE-marked diagnostic viewer, a fully public subprocessor and audit pack, or a self-hosted PACS you operate yourself. Consider PostDICOM or a classic on-prem PACS plus sharing tool when those constraints dominate.

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.

Unomed Cloud PACS

  • Cloud DICOM archive (VNA-style)

    Central archive for studies from in-house modalities and external institutes, with DICOM export so you can take the archive with you. Storage is billed as you grow; long-term statutory retention remains the customer's duty under Unomed's terms.

  • Zero-footprint browser viewer (OHIF default)

    Open studies in the browser with nothing installed on the workstation. OHIF is the default; other viewers can be connected on request. Unomed's GTCs state the standard viewer is not authorised for diagnostic reporting.

  • PACS inbox with assisted patient matching

    Inbound studies land in an inbox; Unomed suggests the matching patient (including fuzzy name matches) and a human confirms. Useful when institutes send studies that do not already carry a clean order from your record.

  • Share via messenger and guest links

    Send studies to colleagues, referrers and patients through Unomed messenger. Recipients without an account get a time-limited guest link; registered users keep the thread in case chat instead of CDs or ad-hoc portals.

  • Cloud Connector, Radiology Bridge and Medical API

    Connect DICOM modalities like a second destination printer, autoroute from an existing institute PACS via Radiology Bridge, or integrate via DICOMweb/Medical API. Keeps on-site PACS investments when you only need outbound routing to Unomed practices.

  • Overlay on existing practice software

    Opens studies from the patient record in supported web-based Swiss practice systems without replacing the PIS. Vendor lists 16+ systems with several official partners; desktop-only software needs a feasibility discussion.

Assurance & compliance: Leaseweb vs Unomed Cloud PACS
Assurance & complianceLogo: LeasewebLeasewebLogo: Unomed Cloud PACSUnomed Cloud PACS
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 found

No public independent security audit report located on unomed.ch.

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.

Not found

No ISO 27001 certificate or registry entry found on the official site.

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 report referenced on public 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

Swiss FADP (DSG) primary; privacy policy also cites GDPR bases. Confirm DPA/ABV for your use case.

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

Swiss entity / no known US parent, but AWS (S3 Zurich region, Rekognition Ireland) and Firebase appear in public technical/privacy materials. 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

GTCs require an Auftragsbearbeitungsvertrag (ABV) when patient data is processed on behalf of the healthcare provider.

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

PACS archive/viewer product; AI is used for assisted patient matching and other suite features, but this entry evaluates the imaging archive, not an AI-centric system.

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.

Non indiqué
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.

Non indiqué
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.

Non indiqué
Diagnostic viewer certificationNon indiqué
Partial

Default OHIF viewer explicitly not for diagnosis per GTCs; certified third-party viewers optional.

Considerations & known limitations: Leaseweb vs Unomed Cloud PACS
Considerations & known limitationsLogo: LeasewebLeasewebLogo: Unomed Cloud PACSUnomed Cloud PACS
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.

Non indiqué
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).

Medium

Privacy policy says processors can be requested at any time but does not name hosting vendors on the page. Blockers for security questionnaires until the annex is shared.

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.

Non indiqué
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.

Non indiqué
US-group cloud components in the data pathNon indiqué
Medium

Even with Swiss HQ and claimed Swiss image hosting, AWS and Firebase endpoints appear in public privacy/CSP materials. Procurement should obtain the named subprocessor annex and assess CLOUD Act residual risk.

Default viewer not for diagnosisNon indiqué
High

If radiologists must report from the included viewer, Unomed alone is the wrong shortlist item unless a certified diagnostic viewer is contracted.

No public ISO/SOC or independent auditNon indiqué
Medium

Assurance currently rests on vendor policies, Swiss entity status and contractual ABV rather than published certificates.

Adéquation

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).

Unomed Cloud PACS

Best fit when

  • Swiss medical or dental practices that want cloud DICOM archive and sharing without an on-site PACS project
  • Teams that must open imaging from an existing web-based practice system rather than a second patient search
  • Institutes that need to autoroute studies to referring practices while keeping an existing PACS (Radiology Bridge)
  • Buyers who prioritise a Swiss contracting entity and vendor-claimed Swiss image residency under the FADP
  • Workflows that share studies with referrers or patients via links instead of CDs or one-off portals

Poor fit when

  • Organisations that require the included viewer to be a certified diagnostic/reporting workstation out of the box
  • Buyers that need a published named subprocessor list and independent ISO/SOC evidence before first sales call
  • Teams seeking a fully self-hosted open-source PACS they operate themselves
  • Hospitals needing a full RIS/PACS suite beyond practice-oriented cloud archive and sharing

Consider instead when

  • When: You need a European cloud PACS peer outside Switzerland or broader multi-country packaging

    Consider: PostDICOM (Netherlands) or other EU cloud PACS vendors

    Feature parity is not claimed; compare residency contracts and viewer certification directly.

  • When: You primarily need raw cloud object storage or hospital-grade imaging services on a hyperscaler

    Consider: AWS or Azure health/imaging stacks with your own viewer and compliance design

    More infrastructure flexibility; you own more of the clinical workflow glue.

  • When: You must keep all image data on premises under your sole operational control

    Consider: Classic on-prem PACS plus a dedicated sharing portal

    Unomed is cloud SaaS with a local connector, not a self-hosted Unomed server product.

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?

Unomed Cloud PACS

  • Will Unomed provide the current named subprocessor list (hosting, backup, email, SMS, identity) under NDA or in the ABV annex?
  • Which exact Swiss data-centre operators and certifications cover the DICOM archive?
  • Is a CE-marked / certified diagnostic viewer required for your reporting workflow, and which third-party option will Unomed integrate?
  • What SLA, backup/RPO and export support apply to your Cloud PACS tier?
