Methodology

Data source

The Observatory is based on the data collected by the MxMap.it project, which maps the MX (Mail Exchange) records of all domains of the Italian Public Administration registered in the Index of Public Administrations (IndicePA).

Quality and limits of the source

IndicePA is the official registry of public bodies, but it is not a clean dataset from which the “normal” (non-PEC) mail domain of each body can be inferred immediately and without reworking: the email domains it contains are often inconsistent, incomplete or absent. For this reason MxMap’s data does not derive from a direct reading of IndicePA, but from a structured reworking — extraction, correction, validation and enrichment of the domains — documented in the MxMap discovery methodology.

The continuous improvement and cleaning of IndicePA is therefore a core functional dependency of the Observatory, to be addressed with a dedicated project, tracked in mxmap.it#2 — Software for a well-maintained and cleaned IndicePA: to measure data quality independently and activate reporting cycles (including via PEC to the bodies and AgID) to correct it at the source.

What we measure

For each body of the Italian PA, we analyse:

  • Email provider: which service manages the body’s email
  • Nationality of the provider: whether the provider is Italian, European or non-European
  • Data jurisdiction: under which legal system the communications data falls
  • Evolution over time: how these parameters change over time

Definition of digital sovereignty

For the purposes of this observatory, we define “digital sovereignty” as the ability of a public body to maintain effective control over its own digital infrastructure and over citizens’ data, with particular reference to:

  1. Jurisdiction: the data remains under Italian/European jurisdiction
  2. Operational control: the body maintains control over its own infrastructure
  3. Technological independence: absence of critical dependence on non-European suppliers

The four sovereignty categories

Every classified body falls into one of four categories, defined by the legal jurisdiction of the provider that manages its email (not by the physical location of the servers):

  • Italian (it): email is managed by an operator subject to Italian law — regional public cloud, Italian commercial provider, or the body’s own infrastructure.
  • EU non-Italian (eu_non_it): a European, non-Italian operator (e.g. OVH, Hetzner, IONOS, Infomaniak).
  • Non-EU / CLOUD Act (extra_eu): an operator subject to non-European jurisdictions — in practice almost always the US clouds (Microsoft 365, Google Workspace), reachable by US CLOUD Act requests wherever the servers are located.
  • Unknown (unknown): the available technical evidence cannot prove who manages the email — see below.

When we declare “Unknown”

“Unknown” is not an error: it is the method’s honest non-verdict. It happens in two cases:

  1. No MX record: the body’s domain declares no mail server at all (certified-mail-only bodies, brochure domains, inconsistent IndicePA records).
  2. Backend behind a gateway cannot be determined: the body’s mail flows through a security gateway (an antispam filter such as Sophos, Libraesva, Proofpoint) that hides the final destination, and no primary signal (corroborated SPF, autodiscover, DKIM) proves what sits behind it. In these cases we do not attribute a provider by presumption: having, say, a Microsoft/Google registration (tenant, verification token) proves the use of cloud licences, not mail hosting.

This choice — preferring a declared “we don’t know” over an unproven attribution — follows the classifier of the MxMap family’s peer-reviewed reference paper, and is why the “Unknown” share is not zero. The full technical criteria are in the MxMap methodology; the bodies in this condition are publicly listed on the anomalies page, with an active reduction roadmap (cross-checking ICT procurement data, active verification, direct outreach to the bodies).

Update frequency

Data is collected periodically and reports are published at regular intervals to monitor its evolution over time.

The Observatory’s methodology is shared with the MxMap family of projects, active in several European countries, and stands alongside other initiatives that measure digital sovereignty with complementary approaches. The full list is on the Related initiatives in Europe page.

What we do not measure yet

This page describes what the Observatory measures today. What is still missing — first of all the measurement of public spending on cloud services, year by year — is set out in the roadmap, together with the state of progress of each piece.
