Philippine banking institutions lead the country in strict DMARC enforcement with a 36.2% reject rate, yet they remain thoroughly exposed to transport-layer interception. The industry remains vulnerable at the transport layer, showing a 100.0% MTA-STS gap across the banking sector where critical transactional data travels via unencrypted paths. Attackers can execute "Downgrade Attacks" to opportunistically strip deployed encryption, intercepting high-value financial confirmation messages to reroute capital or harvest sensitive banking credentials.
Philippine public administration and municipal domains show a stable foundation of technical tracking, matching a 98.2% correct SPF score. However, the sector takes a highly cautious approach to policy escalation, leaving 25.9% at "none", 24.1% at "quarantine", and only a minimal 6.2% threshold at protective "reject" values. Crucially, 43.8% of government domains lack DMARC entirely, allowing threat actors to impersonate official departments to spread false regulatory directives.
Healthcare infrastructure maintains a 97.6% correct SPF baseline, but managing sensitive patient information with low strict enforcement makes it a prime target for data extortion. A significant portion of this infrastructure relies on passive monitoring, while a severe 37.3% lack DMARC entirely. This monitoring-only posture leaves patient portal access routes and internal clinical data systems deeply vulnerable, a problem compounded by an absolute 100.0% lack of adoption for MTA-STS.
The media and broadcasting vertical faces high public visibility, where weak email controls allow bad actors to weaponize an outlet’s public trust. Media domains show a severe 49.5% absence of DMARC records coupled with the lowest-in-country enforcement rate of 5.3%. This lack of active enforcement allows threat actors to easily forge media domain names to distribute fake news stories, false press releases, or phishing emails.
As critical communications gatekeepers, telecom operators maintain an engineering baseline with a 96.2% correct SPF score. Despite this framework, the industry has a low rate of strict p=reject enforcement at 23.1%, favoring reactive postures with 50.0% sitting at p=quarantine. Because half of telecom domains sit passively at quarantine rather than being blocked outright, spoofed messages may still bypass filters to extract subscriber data and facilitate SIM-swap attacks.
Academic centers host vast sums of student data and research intellectual property, showing a 98.4% correct SPF baseline. However, 45.2% of educational domains completely lack DMARC protection, while 25.8% rely on a passive p=none stance. Attackers exploit these missing records to distribute look-alike "Tuition Payment Portal" updates to students or fake peer-review links to faculty to siphon login credentials.
Logistics networks serve as the backbone of regional trade, maintaining a 95.3% correct SPF configuration metric. However, real defense remains limited by missing DMARC records (29.1%) and a reliance on passive monitoring, with 22.1% of domains staying at p=none. This gives criminals an easy opening to copy transport company identities, sending modified shipping manifests or altered routing details to logistics partners to siphon freight payments.
The energy sector displays decent basic alignment but leaves exactly half (50.0%) of its domain ecosystem completely unmonitored and lacking DMARC protection. Criminals can easily spoof equipment manufacturers and utility suppliers to issue fraudulent supply chain requests or introduce malicious files designed to pivot into operational technology environments.
