Matomo by Stackhero

Dedicated bare-metal Matomo instance
Each customer gets an isolated VM on Stackhero’s own bare-metal cloud (Stackhero DC OS), not shared multi-tenant Matomo. Local disks and included Redis are positioned for high IOPS and heavy traffic—fit teams that outgrow noisy-neighbor shared analytics clouds.
Unlimited sites, members, segments, and goals until capacity
Stackhero does not meter websites, team seats, segments, or goals as product SKUs; you scale by instance size (published up to 16 vCPUs / 64 GB RAM). Retention is limited by disk, not a fixed product TTL—plan storage for long history.
One-click Matomo updates and managed ops (no SSH)
Stackhero delivers Matomo updates for dashboard application; firewall IP rules are customer-configurable. SSH is intentionally unavailable on the managed service—good for reduced surface area, poor fit if you need custom OS packages.
Custom domain, GeoIP2, and dedicated notification email
Point matomo.yourdomain.com with TLS 1.3/ECDSA, ship visitor location via bundled GeoIP2, and send unlimited Matomo reports/alerts through a per-instance email path—reduces glue work after first deploy.
Atomic encrypted daily backups (EU vault)
24-hour atomic image backups (plus event-driven backups on upgrades) are validated, then encrypted (OpenPGP ECDH/Curve25519) and retained up to three months. Vendor FAQ states backups are stored in the EU even when regions differ—confirm dual-region implications for US instances.
Hourly billing with EU or US region choice
Spin services up/down with hourly charging and a single monthly invoice; free trial without payment method. Choose European (France) or USA placement at create time—region is a first-class control for residency, not a hidden default.

Piwik PRO

ClickHouse-backed web & mobile analytics
Session-level web and app analytics with custom reports, funnels, user flows, multi-channel attribution, and calculated metrics. Vendor positions unsampled collection by default with optional sampling for extreme volumes, plus raw export via API, files, and BigQuery—aimed at teams that outgrew pre-aggregated MySQL-style tools.
Anonymous tracking when cookies are declined
Collect privacy-safe behavioral signals without identifiers when visitors refuse cookies or when you configure limited measurement modes. Marketing can still see channels and journeys; personal identifiers and full attribution wait for a valid lawful basis—useful under GDPR/ePrivacy friction.
Integrated Consent Manager and Tag Manager
Capture and store consent, drive tag firing from preferences, and handle visitor data requests in-product. Optional Cookie Information CMP and server-side tagging paths reduce the usual glue code between a separate CMP, GTM, and analytics.
Data Activation for real-time personalization
Segment audiences from live behavior and trigger on-site or outbound actions without exporting every event to a second CDP first. Suited to regulated marketers who want activation on first-party data they control.
Selectable cloud residency (Azure + Elastx)
Public cloud regions include Azure US, NL, DE, and HK plus Elastx Sweden; Enterprise private cloud spans 60+ Azure regions and Elastx. Business plan marketing highlights EU-operated Swedish hosting—pick region in procurement, not after go-live.
Regulated-industry packaging (GDPR tooling, HIPAA BAA path)
DPA available on Business signup; Enterprise adds private cloud, higher action volumes, SLAs, and HIPAA Business Associate Agreements for healthcare marketing analytics. Vendor also claims ISO 27001 and SOC 2—request current certificates in diligence.

Assurance & compliance: Matomo by Stackhero vs Piwik PRO
Assurance & compliance	Matomo by Stackhero	Piwik PRO
Independent security / no-logs audit	Not found ISO 27001 and bug-bounty openness claimed; no public independent no-logs audit report specific to analytics found.	Partial Vendor states regular external security audits and SOC 2/ISO programs; no public third-party no-logs-style audit PDF reviewed for this draft. Request reports under NDA.
ISO 27001	Vendor claimed Vendor publishes ISO/IEC 27001:2022 certificate #254338 from the British Assessment Bureau (PDF). Not re-verified against the issuer’s public register in this draft.	Vendor claimed Asserted on privacy-security and platform pages; certificate not independently re-verified against a public registry for this entry.
SOC 2 / SOC 3	Not found No SOC 2/3 claim found on certifications/privacy/GDPR pages reviewed.	Vendor claimed Vendor claims SOC 2 (comparison content references type II) and SOC 2-certified infrastructure; obtain current report in diligence.
GDPR / EU data protection	Vendor claimed French entity; public GDPR & DPA page; customer controller / Stackhero processor model; EU region option for service data.	Vendor claimed EU legal entity, residency options, consent tooling, anonymization, and DPA. Compliance depends on customer configuration and purposes.
US CLOUD Act exposure (indicative)	Partial French entity, no known US parent, non-hyperscaler bare-metal hosting claimed. Medium/partial because USA is a first-class hosting region; EU-only only when the customer creates the service in Europe. Backups stated as EU-stored. Not legal advice.	Partial No known US parent (Polish SA). Medium exposure due to Microsoft Azure as public/private cloud subprocessor and optional US region; Elastx Sweden is EU-operated alternative. Not legal advice.
Data processing agreement (B2B)	Vendor claimed DPA applies automatically with Terms of service; PDF downloadable from the GDPR & DPA page.	Vendor claimed Business DPA linked from Business plan signup (piwik.pro/business-dpa/); Enterprise contracts expand terms.
EU AI Act	Not applicable Web analytics hosting; not positioned as an AI system product.	Not applicable Analytics/activation platform; not marketed as an AI system provider. Customer AI use of exported data is out of product scope.
HIPAA / BAA	Not listed	Vendor claimed HIPAA-oriented offering with BAA on Enterprise path per vendor; not available on all plan tiers.

Considerations & known limitations: Matomo by Stackhero vs Piwik PRO
Considerations & known limitations	Matomo by Stackhero	Piwik PRO
Optional US hosting region	Medium Platform offers USA placement alongside France/EU. Mis-selected region or unclear contract language can put visitor analytics outside the EU. Procurements that require EU-only must pin region at create time and in the order form.	Not listed
EU backups when primary is US	Medium FAQ states backups are stored in the EU. If an instance runs in the USA, confirm whether visitor data is dual-homed (US primary + EU backup) and how that affects DPIA and transfer tools.	Not listed
No SSH / managed-only host	Low Cannot install arbitrary system software or agents; support hours stated as CET office hours for basic platform support—not full Matomo application consulting.	Not listed
Limited named subprocessor list	Medium Privacy policy mentions third-party tools and a payment processor without a detailed public subprocessor register. Request the annex in diligence if procurement requires named processors.	Not listed
ISO certificate vendor-published	Low ISO 27001:2022 is claimed with a public PDF and BAB certificate number; validate scope, sites, and validity dates with the certification body before treating it as verified.	Low ISO 27001, SOC 2, and HIPAA are vendor-claimed. Request certificates/reports and BAA text before treating them as assured.
Matomo privacy configuration is yours	Low Hosting in the EU does not auto-configure consent, IP anonymization, or cookieless modes. Controllers remain responsible for Matomo GDPR tooling and site policy.	Not listed
US-group cloud (Azure) in hosting path	Not listed	Medium Even with EU region selection, Azure introduces US-group infrastructure risk. Pin region, review SCCs/subprocessors, and escalate if policy forbids US cloud groups entirely.
Closed source and no classic self-host	Not listed	Medium Cannot independently audit full source or run fully air-gapped on customer iron. Private cloud still involves vendor-managed stack on Azure/Elastx.
Paid plans only after Core sunset	Not listed	Low Free Core has been discontinued; evaluation relies on trials and paid Business/Enterprise metering by actions/domains.
Compliance depends on configuration	Not listed	Medium Anonymous modes and CNIL exemption require correct setup and purpose limitation. Misconfiguration can recreate the same legal exposure teams left GA to avoid.

Fit

Matomo by Stackhero

Best fit when

Teams that want Matomo’s full analytics/admin surface without running OS or Matomo upgrades themselves
Buyers who prefer a dedicated VM and capacity-based limits over multi-tenant hit metering
Orgs consolidating Matomo with other Stackhero-managed open-source services under one French operator
Projects that need hourly elasticity and the ability to stop billing with one click
Controllers who will configure Matomo privacy features themselves and want a signed/automatic DPA plus ISO 27001 claims

Poor fit when

Requirements that forbid any US hosting option or dual-region backup stories—platform publicly offers USA regions
Teams that need SSH, custom kernels, or non-Matomo system agents on the host
Buyers seeking only a lightweight cookieless pageview product (Plausible-class tools are simpler)
Organizations that must self-host inside their own cloud account with no third-party PaaS operator
Use cases needing a named public subprocessor register beyond Stackhero’s high-level privacy/GDPR pages

Consider instead when

When: You want Swiss Matomo-as-a-Service with cookieless defaults and CH product hosts
Consider: Friendly Analytics
Different operator, residency story, and privacy defaults; still Matomo-based.
When: You need enterprise analytics packaging beyond plain managed Matomo
Consider: Piwik PRO
Compare modules, contracts, and hosting regions independently.
When: You only need a minimal open-source-friendly counter with simple SaaS UX
Consider: Plausible Analytics
Far less Matomo depth; different product surface.
When: You require full root control and in-house residency guarantees
Consider: Self-hosted Matomo on your own EU IaaS
Maximum control; you own updates, backups, and hardening.

Piwik PRO

Best fit when

Regulated marketing/analytics teams that want one suite for measurement, consent, tags, and activation under a Polish legal entity
Public sector and EU enterprises that need selectable EU residency (e.g. Elastx Sweden or Azure NL/DE) plus a formal B2B DPA
Healthcare digital teams evaluating HIPAA-aware analytics with a signed BAA on Enterprise
Organizations leaving GA4 primarily for residency, no vendor ad-network reuse, and anonymous pre-consent measurement options
Teams that need enterprise reporting depth (custom reports, funnels, flows, attribution) beyond lightweight privacy analytics

Poor fit when

Buyers who mandate fully self-hosted open-source analytics with no cloud hypervisor vendor
Sites that only need simple cookieless page analytics without tag management or activation
Teams that refuse any US-group infrastructure (Azure appears in public hosting options even when EU regions are chosen)
Orgs seeking a free forever analytics tier (Core plan sunset; paid Business/Enterprise only)

Consider instead when

When: You need open-source code and true on-premises control
Consider: Matomo (self-host) or Friendly Analytics / Matomo by Stackhero for managed Matomo
Piwik PRO is proprietary cloud/private-cloud only.
When: You want minimal, cookieless EU analytics without enterprise suite complexity
Consider: Plausible Analytics or Simple Analytics
Far smaller feature surface; no HIPAA/CDP-style activation packaging.
When: You need a German enterprise analytics vendor with long public-sector presence
Consider: etracker
Different product depth and packaging—compare consent tooling and activation needs.

Open questions for due diligence

Matomo by Stackhero

Will the order form and DPA annex permanently pin the Matomo instance to the EU (France) region with no US failover?
For US-region instances, what exact data is copied to EU backup vaults and under which transfer mechanism?
Who is the unnamed parent company referenced on the About page, and is there any US ownership or PE?
Can ISO 27001 certificate 254338 be validated on the British Assessment Bureau (or successor) public register for current scope/dates?
Which payment, support, and website analytics providers process Stackhero account data (named subprocessor list)?

Piwik PRO

What exact subprocessor list and backup/DR locations apply to the contracted region (Azure vs Elastx) today?
Can the vendor provide current ISO 27001 certificate scope and SOC 2 Type II report under NDA?
For healthcare: which plan tier, region, and BAA wording cover the intended PHI workflows?
Does the Business Swedish hosting path avoid Azure entirely for production data, or only for selected components?
What residual free/legacy Core accounts remain, and what is the migration deadline for this tenant?
