Latvia
499 domains · composite score 62.4 · surveyed 3 August 2026
Latvia places in the lower third of European countries, with a composite score of 62.4 against a European average of 65.0.
44.3% of Latvia domains enforce DMARC — meaning they instruct receiving servers to quarantine or reject mail that fails authentication. 65.3% publish a DMARC record at all, so the gap between the two is the share that are collecting reports without acting on them.
32.3% still accept TLS 1.0, a protocol deprecated in 2018 and prohibited for systems handling cardholder data under PCI DSS.

Green indicates better than the European average. For TLS 1.0, lower is better.
DMARC policy breakdown
Of the Latvia domains publishing a DMARC record, 38.5% use p=reject, 29.5% use p=quarantine, and 32% use p=none.
A p=none policy provides no protection against spoofing. It is intended as a short monitoring phase while an organisation identifies its legitimate senders, before moving to enforcement.

Method
Based on 499 Latvia domains sourced from the Tranco top-1M and attributed by ccTLD. Organisations using generic TLDs such as .com are not captured, so this measures domains registered under the national suffix rather than all organisations in the country.
