Sender Control Challenges

You can't stop email fraud without full control over your email senders

To gain control, you need full visibility into every internal app, cloud service, and supplier sending email on your behalf. Native email authentication tools provide only partial visibility, which makes it difficult to safely enforce Domain-Based Message Authentication, Reporting, and Conformance (DMARC). As a result, DMARC enforcement is often delayed or incomplete, leaving your domain exposed to email spoofing, phishing, and business email compromise (BEC).

Why Proofpoint

Proofpoint vs. native email authentication tools

CapabilityNative Email Authentication ToolsProofpoint Email Fraud Defense
DMARC deployment Leave implementation, sender discovery, and policy rollout to internal teams Provides guided DMARC implementation through a combination of AI guidance and subject matter experts
Sender visibility Focus on managed mail sources, requiring extra effort to identify all authorized senders Discovers authorized senders across internal systems, consumer mailboxes, cloud services, SaaS apps, and suppliers
Safe enforcement Provide policy controls but limited guidance for validating every sender before enforcement Validates authentication before moving to a DMARC reject policy, reducing disruption
Brand protection Focus on domain authentication rather than broader impersonation threats Detects domain spoofing, lookalike domains, and impersonation threats beyond DMARC
Supplier visibility Provide limited visibility into supplier authentication and third-party email risk Identifies suppliers and surfaces associated risks through threat intelligence
Hosted authentication Require organizations to manage authentication records and infrastructure themselves Simplifies SPF, DKIM, DMARC, and BIMI management though hosted authentication services
Integrated enforcement Authentication and email security enforcement are managed separately Combines DMARC intelligence with email gateway enforcement as a signal to help ensure delivery of legitimate inbound mail from your domains

Frequently Asked Questions

DMARC is difficult to implement because most organizations lack visibility into all email senders using their domain. Without identifying internal systems and third-party services, enforcing DMARC can block legitimate messages. This is why many organizations rely on expert guidance to safely reach enforcement and avoid disruption.

If you enforce DMARC without full visibility into your senders, legitimate email can be quarantined or rejected. This can disrupt business operations as well as customer communications. It also creates risk and reduces trust, especially when critical messages fail to reach customers or partners, which is why organizations often delay enforcement.

Proofpoint Email Fraud Defense combines expert guidance with full visibility into all senders. It helps you validate authentication, safely enforce DMARC, and move to a reject policy without disrupting legitimate email. This approach reduces risk and accelerates time to enforcement.

Native email authentication tools often provide limited visibility into third-party senders and lack guidance for safe enforcement. They also do not address broader risks like domain impersonation and supplier risk exposure. This leaves gaps that attackers can exploit.

DMARC helps stop domain spoofing by blocking unauthorized senders from using your domain. However, it does not stop lookalike domains or all impersonation attacks. Additional protection is needed to detect lookalike domains, monitor impersonation attempts, and assess risk across your supplier ecosystem so you can identify and stop threats early.
