#1of 26 European countries

495 domains · composite score 75.5 · surveyed 3 August 2026

Netherlands places among the strongest in Europe, with a composite score of 75.5 against a European average of 65.0.

63% of Netherlands domains enforce DMARC — meaning they instruct receiving servers to quarantine or reject mail that fails authentication. 83.2% publish a DMARC record at all, so the gap between the two is the share that are collecting reports without acting on them.

13.9% still accept TLS 1.0, a protocol deprecated in 2018 and prohibited for systems handling cardholder data under PCI DSS.

DMARC policy breakdown

Of the Netherlands domains publishing a DMARC record, 47.6% use p=reject, 28.3% use p=quarantine, and 24.1% 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 495 Netherlands 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.

Full method, limitations and raw data are on the survey page.
