Authex is an email authentication platform that helps organizations monitor, validate, and enforce DMARC, SPF, DKIM, BIMI, MTA-STS, and TLS-RPT across all their domains. Email authentication isn't a one-time setup. Authex gives teams continuous visibility across all six protocols, actionable insights from real DMARC report data, and a controlled path from monitoring to full enforcement. How It Works Organizations start with a domain scan to understand protocol coverage, configuration gaps, and current exposure. Domains are then brought into Authex for continuous monitoring of DNS state, report data, deliverability signals, and mail-security findings. From there, guided recommendations, validation workflows, and approval controls help teams move toward stronger policy with less operational risk. Autonomous Agent The Authex agent monitors DNS records and aggregate reports continuously, evaluates compliance over time, and recommends the next safest action for each domain. It runs 27 deterministic rules covering DMARC enforcement progression, SPF hygiene, DKIM key rotation, MTA-STS upgrades, TLS-RPT monitoring, and blacklist response. Every action includes a before/after preview, risk assessment, and full rollback capability. Start in monitor mode, review suggested fixes, or allow automatic low-risk changes while keeping higher-risk decisions under your control. Operational Depth Authex connects the workflows that security, IT, and domain owners typically handle across separate tools: - Aggregate reports, failure reports, and TLS reports provide the visibility needed to understand sending behavior, investigate authentication failures, and monitor transport-security outcomes. - Domain scanning, tagged test messages, authentication verification, inbox placement testing, and blacklist monitoring across 80+ DNSBLs with contextual attribution. - Microsoft 365 mail-security auditing with read-only access to identify policy weaknesses affecting both protection and deliverability. - Rule-based alerts for DNS changes, compliance drops, new threats, phase transitions, and completed agent actions. Managed Services Authex provides fully managed versions of all six protocols. OneSPF handles SPF flattening with automatic updates when upstream providers change IP ranges. Managed DKIM supports automatic selector detection across major providers. Managed MTA-STS and TLS-RPT handle transport-layer security configuration. Benchmark Intelligence Authex is informed by The Index, a benchmark dataset tracking email authentication posture across hundreds of thousands of domains. The Index organizes results by country, TLD, sector, and provider so teams can compare their posture against the broader ecosystem. Compliance Authex helps organizations monitor and improve posture against Google and Yahoo bulk-sender rules, PCI DSS 4.0, NIST SP 800-177 guidance, and DORA requirements.
