Sweden’s financial institutions lead the country in email perimeter defense, maintaining a 90% correct SPF rate and a 84% baseline DMARC deployment rate. Crucially, 51% of financial domains run strict p=reject rules, the highest rate of defensive enforcement across all studied sectors. However, the industry remains vulnerable at the transport layer, showing slow adoption of advanced transit encryption protocols.
Swedish public administration and municipal domains show a stable foundation of technical tracking, matching an 85% correct SPF score with a 75% DMARC adoption rate. However, the sector takes a highly cautious approach to policy escalation, leaving 33% at "None", 15% at "Quarantine", and only 27% at protective "Reject" thresholds. While tying for the national lead in transport encryption, active MTA-STS adoption remains low at just 6%.
Healthcare infrastructure maintains an 83% DMARC adoption footprint and an 84% correct SPF baseline. However, a significant portion of this infrastructure relies on passive monitoring, recording the country's highest concentration of the look-only p=none policy at 42%. This monitoring-only posture leaves patient portal access routes and internal clinical data systems vulnerable, a problem compounded by an absolute 0% adoption rate for MTA-STS.
The media and broadcasting vertical is the least protected sector within the Swedish digital landscape, trailing other industries with a low 69% DMARC adoption rate. Media domains also show the highest rate of missing or misconfigured SPF records at 16%, and the lowest correct SPF deployment rate at 77%. This lack of active enforcement allows threat actors to easily spoof trusted news sources to spread misinformation or execute phishing campaigns.
As critical communications gatekeepers, Swedish telecom providers maintain a stable technical foundation with an 82% correct SPF score and a 78% DMARC adoption metric. Despite this framework, the industry has the lowest rate of strict p=reject enforcement in the country at just 20%, favoring passive p=none monitoring instead at 37%. This lack of active enforcement is compounded by a total 0% adoption rate for MTA-STS across the sector.
Swedish universities and higher education institutions manage highly decentralized sending architectures, showing a 75% overall DMARC adoption rate and an 82% correct SPF baseline. However, 32% of educational domains rely on a passive p=none stance, leaving academic research networks exposed to exploitation. The sector ties for the highest MTA-STS implementation rate in Sweden, though it remains a nominal 6%.
Logistics networks serve as the backbone of regional trade and provide a strong foundation, leading all Swedish sectors with a 95% correct SPF configuration metric. The industry also holds a high 81% DMARC adoption rate. However, real defense remains limited by a clear reliance on passive monitoring, with 33% of domains staying at p=none.
