PowerDMARC Splunk Integration: Unified Email Security Visibility

Email authentication data is only powerful when it’s visible where your security teams already work. That’s exactly what the PowerDMARC–Splunk integration delivers.

By connecting PowerDMARC with Splunk, organizations can bring critical email authentication and domain security insights directly into their existing SIEM workflows, without added complexity. The result? Faster visibility, smarter correlation, and stronger control over email-based threats.

PowerDMARC Splunk Integration Technical Guide

Why Email Authentication Data Belongs in Your SIEM

Domains are one of the most abused attack surfaces in phishing, spoofing, and brand impersonation campaigns. With the PowerDMARC Splunk integration, teams gain a more complete and centralized view of what’s happening across their domains and email channels.

The integration is designed to be lightweight and flexible. Organizations, MSPs, and SOC Teams can connect PowerDMARC to Splunk using secure APIs and begin ingesting email authentication data with minimal effort. There’s no need for heavy customization or platform changes: just connect, run, and monitor.

As a result, investigations into spoofing or phishing attempts become faster and more accurate, and all configuration changes can be traced across a single interface.

Built for Enterprise SOC Teams

SOC teams funnel logs and telemetry from across the environment into Splunk. This gives them one place to spot suspicious behaviors across the whole attack surface instead of checking dozens of tools separately. With PowerDMARC integrated, analysts can:

See authentication failures tied to specific domains or services
Map phishing attempts to specific identities or sources
Map attacker behavior for internal investigations and retrospectives
Collect evidence for internal and regulatory audits

Scalable Visibility for MSPs & MSSPs

Many MSPs/MSSPs support dozens or hundreds of customer domains, each generating authentication data that must be monitored.

With PowerDMARC Splunk integration, they can:

Consolidate PowerDMARC telemetry across all managed tenants
Offer a whitelabeled full-stack email authentication suite as part of their MSP offerings
Standardize visibility, monitoring, and management without manual effort

Key Capabilities Enabled by the PowerDMARC Splunk Integration

PowerDMARC’s Splunk support is engineered for practical security outcomes, enabling:

1. Email Authentication Data Enrichment

PowerDMARC enriches Splunk with contextual metadata, such as sending sources and authentication outcomes, making it easier for teams to investigate malicious activities without extra parsing work.

2. Domain Trust Health Monitoring

Gain continuous visibility into domain trust signals like authentication pass rates, policy enforcement trends, and delivery-impacting misconfigurations, helping organizations improve email reliability while minimizing brand misuse.

3. Threat Investigations

Ingest PowerDMARC’s reporting data and threat intelligence feeds directly into Splunk for quicker, deeper investigations into phishing attempts and spoofing sources.

4. Multi-Tenant & Multi-Domain Flexibility

For organizations managing many domains, PowerDMARC consolidates scattered authentication visibility into Splunk. This makes it Ideal for large enterprises and MSPs with distributed domain portfolios.

5. Seamless SIEM Integration Workflow

By leveraging the PowerDMARC API, organizations can build a streamlined SIEM integration without complex configurations – simply connect, run, and gain centralized visibility into their email security posture across all domains.

A Stronger Security Posture, End to End

Email remains one of the most exploited attack vectors. By integrating PowerDMARC with Splunk, organizations gain a clearer view of how their domains are protected and where attention is needed, without adding operational overhead.

PowerDMARC + Splunk helps security teams move from isolated monitoring to unified defense, ensuring email authentication is no longer a blind spot in the SIEM.
