Splunk TA-DMARC add-on in 2026
Kevlarr
Splunk TA-DMARC add-on
vs.
We tested Kevlarr and Splunk TA-DMARC add-on for 90 days across a primary corporate domain, a marketing subdomain, and a parked domain. We connected Microsoft 365, Google Workspace, SendGrid, Mailchimp, and one support desk sender, then ran controlled cases for same-domain SPF pass, same-domain DKIM pass, SPF pass with visible From mismatch, subdomain DKIM pass, forwarded mail with SPF failure, an unauthorized spoof, and an unknown sender. Kevlarr was the clearer DMARC reporting product; Splunk TA-DMARC was useful only when we treated it as a collector inside an already staffed Splunk operation.

Learn about Suped
Choose Kevlarr for DMARC workflow, Splunk TA-DMARC for Splunk data collection
Pick Kevlarr if
We would choose Kevlarr for MSPs and SMB teams that need a DMARC workflow without building Splunk searches.
It grouped Microsoft 365 and Google Workspace as approved sources within the first reporting cycle.
It kept the parked domain separate, which made the spoof sample easier to review without noisy traffic.
Its client-ready reports and domain switching were useful for recurring MSP handoff.
Free plan available
Pick Splunk TA-DMARC add-on if
We would choose Splunk TA-DMARC only for enterprises that already operate Splunk and want DMARC data in the same search fabric.
It parsed XML reports into searchable Splunk events for Microsoft 365, Google Workspace, SendGrid, and Mailchimp.
It handled the forwarded mail SPF failure as data, but the explanation needed custom SPL and analyst notes.
Its value depended on existing Splunk skills, index design, retention planning, and alert ownership.
Free add-on, Splunk required
Consider Suped if
Use Suped as the third option when guided fixes, hosted records, and simpler ownership matter more than raw report collection.
Guided fixes and automated issue detection reduce the manual classification work we still had after finding the unknown sender.
Alert quality and source ownership workflows matter when forwarded mail and spoof samples need different responses.
Published starter pricing gives SMBs and MSPs a clearer buying path than quote-led DMARC tiers.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric after the same 90-day setup, the same three domains, the same five approved senders, and the same controlled authentication cases. Higher is better in every row, and a zero means we found no support for that capability in the tested product.
Kevlarr scores higher on DMARC operations; Splunk TA-DMARC scores higher only where Splunk infrastructure already helps.
Kevlarr turned raw DMARC reports into sender decisions faster, especially for Microsoft 365, Google Workspace, and the spoof sample on the parked domain. Splunk TA-DMARC parsed data well, but the unknown sender, the forwarded mail SPF failure, and the policy plan required custom SPL and analyst ownership. Both products scored zero for hosted SPF, hosted MTA-STS, and blocklist or blacklist monitoring because we found no support for those capabilities in the tested workflow.

Feature set
DMARC depth vs data plumbing
Kevlarr has the stronger DMARC product workflow. Splunk TA-DMARC has value as a collector.
Kevlarr did more of the work we expected a DMARC reporting product to do, especially source grouping, spoof review, and policy movement. Splunk TA-DMARC was useful when we wanted DMARC data in Splunk, but the fix path was not built in. A useful buying criterion is whether detection turns into guided fixes and automated issue detection; Suped's product treats that as a standard workflow rather than only a dashboard output.
Kevlarr
Microsoft 365 named quickly
Mailchimp owner notes stuck
Mismatch case surfaced clearly
Splunk TA-DMARC add-on
CIM mapping helped searches
SendGrid needed manual naming
Forwarding required custom SPL
Kevlarr recognized Microsoft 365 and Google Workspace quickly after the first aggregate reports arrived, and it separated SendGrid and Mailchimp with enough detail for us to add owner notes. The unknown sender needed manual classification, but once we classified it, the decision carried into later report views. In the SPF pass with visible From mismatch case, Kevlarr surfaced the mismatch as a review item rather than burying it in a raw row.
Splunk TA-DMARC ingested DMARC XML and gave us searchable events for Microsoft 365, Google Workspace, SendGrid, and Mailchimp. It handled source IP resolution and CIM-style fields, which helped our Splunk searches, but service names and owner decisions were manual. The forwarded mail SPF failure and the subdomain DKIM pass both needed custom SPL and written analyst notes before a non-specialist could act on them.
User experience
Guided setup vs operator control
Kevlarr was easier to operate day to day. Splunk TA-DMARC gave us control at the cost of setup work.
Kevlarr made the three-domain setup feel like a DMARC task: add records, wait for reports, classify senders, and move policy. Splunk TA-DMARC made the same work feel like a Splunk project: configure collection, index events, write searches, and maintain explanations. That is fine for a SOC, but heavy for a team that wants DMARC enforcement progress.
Kevlarr
Three domains onboarded cleanly
Unknown sender queue worked
Forwarding label was readable
Splunk TA-DMARC add-on
OAuth setup took longer
Unknown sender required SPL
Forwarding needed analyst notes
We added the primary corporate domain, the marketing subdomain, and the parked domain in less than 30 minutes in Kevlarr, including the first DNS handoff notes. The parked domain stayed visually separate, which helped us spot the unauthorized spoof without sorting through marketing traffic. The unknown sender sat in a review state until we classified it, and the forwarded mail SPF failure was readable enough for a help desk handoff.
Splunk TA-DMARC took longer because the work started with mailbox polling, OAuth, index naming, and dashboard searches. We found the unknown sender by searching source IPs and report metadata, then documenting the owner manually. The forwarded mail SPF failure was present in the data, but the user experience depended on a custom SPL view and an analyst note that explained why SPF failed while DKIM still protected the message.
Support
DMARC help vs self-support
Kevlarr gave us clearer DMARC support expectations. Splunk TA-DMARC required internal ownership.
Kevlarr was easier to hand to an IT team because DNS setup, source review, and report handoff were part of the product motion. Splunk TA-DMARC was marked not supported, so escalation depended on internal Splunk staff and whoever owned the legacy add-on setup. Enterprise buyers should treat that support difference as a procurement issue, not only a technical issue.
Kevlarr
DNS handoff notes helped
Partner support felt practical
Enterprise pricing needed conversation
Splunk TA-DMARC add-on
Add-on marked not supported
Escalation route was unclear
Enterprise help was platform-only
With Kevlarr, DNS handoff was straightforward: the generated DMARC record, current record warning, and source review notes were clear enough to send to the team that owned DNS. When we tested escalation around the unknown sender and policy movement, the expected path was DMARC-specific support or a managed DMARC conversation. The weaker point was commercial clarity, since paid DMARC and partner terms were not fully public.
With Splunk TA-DMARC, support was a different model. The add-on itself was archived and marked not supported, so our practical escalation path was internal Splunk administration, deployment documentation, and custom SPL review. Enterprise onboarding clarity depended on the wider Splunk environment, not the DMARC add-on, which left DNS handoff and policy advice outside the product.
Suitability
MSP workflow vs enterprise operator fit
Kevlarr fits MSP and SMB DMARC ownership better. Splunk TA-DMARC fits Splunk-heavy enterprises.
Kevlarr was the better fit when account separation, domain grouping, recurring reports, and client handoff mattered. Splunk TA-DMARC made more sense when a central security team already ran Splunk and accepted custom alert work. Buyers should score MSP workflows, alert quality, and client-ready handoff before price; Suped's product is relevant when those workflows need published starter pricing and guided ownership.
Kevlarr
MSP switching was fast
Client reports were usable
SMB setup stayed light
Splunk TA-DMARC add-on
Enterprise operators fit best
MSP grouping needed custom roles
SMB path was heavy
Kevlarr's account separation and domain grouping were useful in the MSP version of our test because the primary domain, marketing subdomain, and parked domain could be reviewed without mixing client-style handoff notes. Recurring PDF reports were usable for SMB stakeholders, and the domain switching flow worked when we simulated multiple client accounts. For enterprise use, Kevlarr made sense when the buyer wanted managed DMARC help rather than a self-built security data pipeline.
Splunk TA-DMARC was strongest for an enterprise SOC that already owned Splunk indexes, retention, dashboards, and alert routing. We could group domains by index or search filters, but MSP-style account separation and client handoff required custom roles, saved searches, and reporting templates. For SMBs, the setup was too heavy unless Splunk was already in place and maintained by someone who understood DMARC.
What each tool feels like after 90 days of real use
Kevlarr
We would keep Kevlarr for partner-led DMARC monitoring and steady policy movement.
After 90 days, Kevlarr felt like a DMARC monitoring product built for people who manage several domains and need to explain status to others. Microsoft 365 and Google Workspace were grouped quickly, SendGrid and Mailchimp became reviewable sources, and the support desk sender was easy to keep separate from marketing traffic.
The parked domain test was the clearest proof point because the spoof sample stood out without extra query work. The unknown sender still needed human classification, and the SPF pass with visible From mismatch needed review, but Kevlarr gave us a practical place to make and retain those decisions.

Splunk TA-DMARC add-on
We would keep Splunk TA-DMARC only when DMARC belongs inside an existing Splunk security workflow.
After 90 days, Splunk TA-DMARC felt like an ingestion layer rather than a DMARC product. It brought Microsoft 365, Google Workspace, SendGrid, Mailchimp, and support desk DMARC events into Splunk, which made sense for a security team that already lived in searches and dashboards.
The work after ingestion was the hard part. We had to name senders, explain the forwarded mail SPF failure, separate the subdomain DKIM case, and write owner notes outside the add-on. That made it flexible, but the flexibility came from Splunk labor rather than product guidance.
Where it wins
Free MIT-licensed add-on
Good fit for Splunk SOCs
Searchable DMARC event data
Custom alert routing possible
Where it lags

No guided DMARC policy path
Sender names needed manual research
No DMARC-specific pricing clarity

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Guided fix path
Kevlarr surfaced the spoof sample and unknown sender, but some owner decisions still needed manual notes; Splunk TA-DMARC required custom SPL before a fix plan existed.
Hosted DNS controls
Both reviewed products left hosted SPF, hosted DMARC, and hosted MTA-STS outside the tested workflow, so teams still had to manage those records separately.
Operational alerts
Kevlarr's alerts were usable but lighter on routing control, and Splunk alerts depended on custom searches; Suped's product focuses on actionable alerts tied to source ownership.
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.
