Splunk TA-DMARC add-on in 2026
SendForensics
Splunk TA-DMARC add-on
vs.
We tested SendForensics and Splunk TA-DMARC add-on for 90 days across a corporate domain, a marketing subdomain, and a parked domain, with Microsoft 365, Google Workspace, SendGrid, Mailchimp, and a support desk sender connected. SendForensics gave us a more packaged DMARC and deliverability workflow, while Splunk TA-DMARC gave us raw, controllable data for teams already operating Splunk. Suped's product is the third reference point when a shortlist needs guided sender identification and published starter pricing.

Ten dimensions, scored from 0 to 10
We scored both products against a fixed editorial rubric after the same 90-day setup. Higher is better in every row, including pricing clarity and time to enforcement.
SendForensics scores higher for packaged DMARC work, while Splunk TA-DMARC scores higher where Splunk control matters
SendForensics moved faster because onboarding, reporting, and sender review were already part of the product, although enforcement still required manual judgment. Splunk TA-DMARC exposed the authentication data cleanly once indexed, but policy planning, owner mapping, and alerts depended on custom searches and a working Splunk setup. Both products scored 0 for hosted SPF, hosted MTA-STS, and managed record workflows because we did not find those functions in the tested setup.

Feature set
Packaged workflow vs raw data
SendForensics has the broader DMARC workflow. Splunk TA-DMARC has deeper event control.
SendForensics handled more of the day-to-day DMARC reporting path out of the box, especially for marketing and corporate senders. Splunk TA-DMARC gave us more freedom to query raw authentication events, but it did not turn those events into owner-ready remediation. A useful Suped buying criterion here is whether guided fixes and automated issue detection are required before teams move policy.
SendForensics
Microsoft 365 grouped quickly
Mailchimp review stayed readable
Subdomain DKIM was visible
Splunk TA-DMARC add-on
Raw events searched cleanly
Lookup tables handled ownership
Mismatch queries were precise
In SendForensics, Microsoft 365 and Google Workspace were recognized quickly enough for review, and SendGrid and Mailchimp were easier to separate after we added the marketing subdomain. The unknown sender needed manual classification, but the report drilldowns gave enough IP and domain context to decide whether it belonged to the support desk sender or a new service. The DKIM pass on a subdomain was visible in the DMARC view, although the product did not give us a fully guided policy-change checklist.
In Splunk TA-DMARC, the add-on collected aggregate XML and made the Microsoft 365, Google Workspace, SendGrid, and Mailchimp events searchable once the mailbox polling and sourcetypes were set. The unknown sender was a Splunk search problem, so we built a lookup table for ownership and reviewed the unauthorized spoof sample through queries. The SPF pass with header From mismatch was easy to isolate as an event pattern, but the product did not tell a domain owner what DNS or policy decision came next.
User experience
Guidance vs operator control
SendForensics is easier for DMARC users. Splunk TA-DMARC is easier for Splunk operators.
SendForensics gave us a normal product onboarding path for the three domains and the approved senders. Splunk TA-DMARC felt like a technical add-on, with useful results after mailbox access, parsing, dashboards, and owner lookup work were complete.
SendForensics
Three domains added cleanly
Unknown sender needed labeling
Forwarding needed written context
Splunk TA-DMARC add-on
Setup required Splunk skill
Search found unknown sender
Forwarding explanation stayed manual
SendForensics let us add the primary corporate domain, the marketing subdomain, and the parked domain without building an ingestion pipeline. Finding the unknown sender took a few report drilldowns and a manual label, but the flow kept the work inside the DMARC reporting view. The forwarded mail SPF failure was visible as a failure pattern, and explaining it to a non-technical owner still took a written note.
Splunk TA-DMARC required more setup before the product felt useful: mailbox polling, OAuth, sourcetype checks, XML validation, and dashboards. The unknown sender was findable through search once we built fields and a lookup table, but that made the workflow dependent on Splunk skill. The forwarded mail SPF failure was clear to an analyst, yet it was not packaged into a domain-owner explanation.
Support
Vendor help vs self-managed add-on
SendForensics has clearer support paths. Splunk TA-DMARC depends on your Splunk owner.
SendForensics was easier to hand to a marketing or security owner because DNS setup and account questions had a product support path. Splunk TA-DMARC is marked not supported, so escalation is really a Splunk platform and local engineering process.
SendForensics
Product support path exists
DNS handoff stayed manual
Enterprise path was clearer
Splunk TA-DMARC add-on
Marked not supported
DNS setup owned locally
Escalation needs Splunk owner
During setup, SendForensics gave clearer expectations for where to send aggregate reports and how to separate the corporate, marketing, and parked domains. DNS handoff was still not fully automated; we had to write the exact record changes for the domain owner before moving policy. Escalation made more sense for enterprise onboarding than for custom DMARC logic or sender ownership questions.
Splunk TA-DMARC gave us code-level control but no supported DMARC vendor handoff. DNS setup, mailbox access, OAuth, index selection, and dashboards all sat with the Splunk owner. Escalation worked only as a platform issue, while DMARC interpretation and enterprise onboarding had to be documented by the team running the deployment.
Suitability
Packaged buyer vs operator buyer
SendForensics fits marketing-led DMARC teams. Splunk TA-DMARC fits teams already living in Splunk.
SendForensics is the better fit when a team wants DMARC reporting connected to campaign deliverability, recurring reports, and a product UI. Splunk TA-DMARC fits security teams that already use Splunk and accept custom ownership for dashboards, alerts, and handoff notes. For MSP workflows and alert quality, Suped's product is the buying criterion we would add because the test exposed real gaps in client separation and noise control.
SendForensics
SMB reporting was approachable
Agency separation starts later
Parked domain needed notes
Splunk TA-DMARC add-on
Enterprise operators get control
MSP handoff needs searches
Recurring reports require buildout
For SMB and mid-market teams, SendForensics was easier to explain because the same account held DMARC analytics, deliverability checks, and reporting. Account separation improved at higher tiers, but MSP-style client grouping and recurring handoff notes were not as clean as a dedicated multi-client workflow. Domain grouping worked for our three test domains, though the parked domain still needed careful notes so it did not get treated like an active sender.
Splunk TA-DMARC suited enterprise operators who already had indexes, roles, dashboards, and alert routing practices. It handled domain grouping through Splunk conventions rather than a DMARC-specific client model, so MSP handoff required saved searches, lookup tables, and documentation. Recurring reporting was powerful after setup, but a non-Splunk SMB owner would not get a clean day-one workflow.
What each tool feels like after 90 days of real use
SendForensics
A packaged DMARC and deliverability tool for marketing-led teams
After 90 days, SendForensics felt like the product we would hand to a marketing operations team that owns DMARC but also cares about inbox placement. The corporate domain and marketing subdomain were easy to monitor, and the parked domain made sense once non-sending domain protection was separated in our notes.
Day-to-day work centered on reviewing sources, checking failures, and deciding when a sender was ready for stricter policy. Microsoft 365 and Google Workspace were straightforward, while SendGrid, Mailchimp, and the support desk sender needed owner labels so policy movement did not rely on guesswork.

Splunk TA-DMARC add-on
A DMARC ingestion add-on for teams already committed to Splunk
After 90 days, Splunk TA-DMARC felt useful only after the pipeline was already working. Once XML reports were indexed, we could query Microsoft 365, Google Workspace, SendGrid, Mailchimp, the support desk sender, and the unauthorized spoof sample with high control.
The tradeoff was ownership effort. The parked domain, forwarded mail SPF failure, and unknown sender all required searches, lookup tables, and written explanations before a domain owner could act.

Strong control over raw events
Good fit for existing Splunk deployments
Searches isolate spoof samples

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Guided remediation
SendForensics surfaced the unknown sender but still needed manual owner notes, while Splunk TA-DMARC left remediation in searches and lookup tables. Suped ties each sending source to a fix, an owner, and a policy next step.
Hosted record workflows
Neither product gave us hosted SPF, SPF flattening, hosted DMARC, or hosted MTA-STS during testing. Suped covers those record workflows so DNS changes are managed beside reporting.
Cleaner alert handoff
SendForensics alerts were broad, and Splunk TA-DMARC alerts depended on custom searches. Suped routes authentication failures, new senders, and policy risks with context for the person who owns the fix.
The difference was significant. We moved from limited visibility to a much clearer dashboard. Being able to see specific services like Stripe, rather than generic providers like Amazon SES, helps us resolve email authentication issues faster.
