Each proven domain can be compared with organisations of the same kind measured by Perimetry Research, our public studies: the French communes by size, the intercommunalities, départements and regions, the universities and higher education establishments, and, for a business or an association, the .fr domains (a random sample of the registry’s open data); hospitals and clinics will follow when their study is published. Only the published figures of the study are used: nothing about other customers of Perimetry. It is included in every plan; the comparison also appears in the PDF report and in the monthly client report.

Choose the group

Open the domain and go to Compared with your peers.
In Compare with, choose your group: French communes and their size (fewer than 1,000 inhabitants up to 100,000 or more), an intercommunality by category or population, a département or a region, a kind of university or school, or the .fr domains: all active ones, or those of the same age, mail provider or kind of site. No comparison removes it.
For the communes and local authorities, in Public contact e-mail address, say where the address published in the official directory is: on your own domain, or on a consumer mailbox (Gmail, Orange…). The audit cannot see it; you can also leave this check out.
Press Save.

What you see

The headline: your grade on the study’s checks and the share of the group with a lower grade, for example “A better grade on the study’s checks (C) than 63% of French communes of 1,000 to 5,000 inhabitants; 31% have the same grade.” When the study publishes the distribution of its scores, it becomes an exact percentile: “Better protected than 70% of…”.
Check by check: valid HTTPS certificate, HTTP sent to HTTPS, HSTS of six months or more, basic protective headers, DNSSEC, CAA, strict SPF, DMARC, DMARC enforced, and the contact address. For each, whether this domain passes, and the share of the group that does.
The source: the edition of the study and the number of bodies or domains graded in the group, with links to the study and its methodology.

In the free check too

Anyone can see the same comparison without an account: under the result of the free check, choose your kind of organisation. The contact address check is left out there, since a free check cannot see it.

Not your Perimetry Cloud score

The study grades ten simple checks, pass or fail, the same way for every commune; the comparison judges your domain on those same checks, with the same rules, read from its latest audit. Your Perimetry Cloud score counts many more things and weighs them by severity: the two numbers measure different things and are not compared with each other. A check whose answer is unknown is left out, as in the study; with fewer than three checks judged, no grade is given.

Two small differences remain, because the comparison reads an audit rather than the study’s own scan: the site judged is your domain’s own address (or www when the domain itself does not answer), where the study reads the address published in the official directory; and the protective headers are read on a web page, as the audit does.
