Free compliance check mapped to the PCI-DSS 4.0.1 controls that touch email — anti-phishing (5.4.1), strong cryptography (4.2.1), log monitoring (10.4.1), and sender authentication (6.4.1, 8.2). Instant, no signup, results in seconds.
Scanning PCI-DSS email controls…
Skysnag Security
Skysnag enforces DMARC, monitors encryption channels, and provides the audit trail your assessor needs to satisfy PCI-DSS email controls — all in one platform.
Skysnag automates every email-security control PCI-DSS 4.0.1 requires — DMARC enforcement, MTA-STS policy management, TLS-RPT monitoring, and audit-ready evidence exports. One platform, every framework, zero manual remediation cycles.
DMARC Enforcement
Automated policy uplift to p=reject with continuous DMARC report monitoring (Req 5.4.1)
MTA-STS Management
Automated MTA-STS policy publishing and mode=enforce progression (Req 4.2.1)
TLS-RPT Monitoring
Daily parsing of TLS delivery failure reports with actionable alerts (Req 10.4.1)
Audit-Ready Exports
Evidence packages mapped to each PCI-DSS requirement for QSA review
SIEM Integration
Route DMARC and TLS-RPT alerts to your incident response platform (Req 12.10.5)
Cross-Framework View
Single compliance dashboard covering PCI-DSS, SOC 2, ISO 27001, and NIS2
PCI-DSS 4.0.1 is the Payment Card Industry Data Security Standard enforced by Visa, Mastercard, American Express, Discover, and JCB on any entity that stores, processes, or transmits cardholder data. Several requirements explicitly touch email — anti-phishing, encryption in transit, log monitoring, and sender identity. Skysnag maps the email layer of your compliance program to the underlying DNS records and authentication posture a QSA will verify.
PCI-DSS 4.0.1 Requirement 5.4.1 requires technical controls to detect and protect from phishing attacks. DMARC at p=quarantine or p=reject is the recognized email-layer implementation, blocking domain spoofing attacks against your employees and customers.
Requirement 4.2.1 mandates strong cryptography for PAN transmission over open networks. For email, this is enforced via MTA-STS in mode=enforce. Cleartext SMTP and opportunistic TLS without policy enforcement do not satisfy this control.
Requirement 10.4.1 requires daily review of audit logs for anomalies. DMARC aggregate reports (rua=) and TLS-RPT reports provide the email-layer telemetry. Reports must be parsed, stored, and reviewed — not left unread in a mailbox.
Requirement 12.10.5 requires security monitoring alerts to be included in the documented incident response plan. DMARC and TLS-RPT alerts must be routed to your SIEM, ticketing system, or security team — not to an unmonitored alias.
Requirements 6.4.1 and 8.2 require user and system identity verification. At the email layer, SPF authenticates sending IPs and DKIM cryptographically signs each message. Both must be aligned with the From: domain for valid DMARC.
These same controls map to SOC 2 CC6.1, CC6.6, CC6.7; ISO 27001 Annex A 5.14 (Information transfer); and NIS2 Article 21 (Cybersecurity risk-management measures). One remediation satisfies multiple frameworks.
