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.

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.

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: Seeweb vs Unomed Cloud PACS
Assurance & compliance	Seeweb	Unomed Cloud PACS
Independent security / no-logs audit	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.	Not found No public independent security audit report located on unomed.ch.
ISO 27001	Vendor claimed Vendor certifications page: ISO/IEC 27001:2022, AXE REGISTER cert IT18-27702D, valid until 28 Nov 2027; locations Milan & Frosinone. Re-verify serial in procurement.	Not found No ISO 27001 certificate or registry entry found on the official site.
ISO/IEC 27017 (cloud security)	Vendor claimed Appendix to ISO 27001 certificate on certifications page; same validity window stated.	Not listed
ISO/IEC 27018 (cloud PII)	Vendor claimed Appendix to ISO 27001 certificate on certifications page; same validity window stated.	Not listed
SOC 2 / SOC 3	Not found No SOC 2/3 report advertised on the official certifications page at research time.	Not found No SOC 2/3 report referenced on public pages reviewed.
CISPE Data Protection Code of Conduct	Vendor claimed Vendor states CISPE registry presence and European data storage under the Code (since 31 May 2017 on certifications page).	Not listed
ACN Qualified CSP (QI2/QC2)	Vendor claimed IaaS qualification for Italian PA; QI2 infrastructure and QC2 for listed products including AI/supercomputing infrastructures (19 Jan 2023 on certifications page).	Not listed
CSA STAR Level 1	Vendor claimed Stated for Virtual Private Cloud and Foundation Server PRO (6 July 2022 on certifications page).	Not listed
GDPR / EU data protection	Vendor claimed Italian controller/processor entity, European hosting messaging, privacy policy, ISO 27018 claim, CISPE; confirm DPA for your processing roles.	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 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.	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 Art. 28 DPA language used for Seeweb-operated services (e.g. published for Regolo); request current signed DPA + TOMs + subprocessors for core cloud/IaaS contracts.	Vendor claimed GTCs require an Auftragsbearbeitungsvertrag (ABV) when patient data is processed on behalf of the healthcare provider.
EU AI Act	Partial Infrastructure/GPU provider and Rethic.AI partnership messaging; AI Act duties mainly fall on customer AI systems. Not a full provider high-risk AI assessment by EuropeanStack.	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.
Diagnostic viewer certification	Not listed	Partial Default OHIF viewer explicitly not for diagnosis per GTCs; certified third-party viewers optional.

Considerations & known limitations: Seeweb vs Unomed Cloud PACS
Considerations & known limitations	Seeweb	Unomed Cloud PACS
Smaller global footprint than hyperscalers	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.	Not listed
Certifications are vendor-published	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.	Not listed
No single public subprocessor register found	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.	Not listed
GPU Spot Instances can be interrupted	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.	Not listed
Some sites use third-party data centers	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.	Not listed
US-group cloud components in the data path	Not listed	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 diagnosis	Not listed	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 audit	Not listed	Medium Assurance currently rests on vendor policies, Swiss entity status and contractual ABV rather than published certificates.
Subprocessor list not published	Not listed	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.

Fit

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.

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

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?

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?
