Splunk TA-DMARC add-on in 2026
Send-Shield
Splunk TA-DMARC add-on
vs.
We tested Send-Shield and Splunk TA-DMARC add-on for 90 days across a corporate domain, a marketing subdomain, and a parked domain. Send-Shield is the more practical route for teams that want a managed DMARC reporting workflow, while Splunk TA-DMARC add-on fits operators who already live in Splunk and accept a hands-on archived collector.

Choose Send-Shield for guided DMARC, choose Splunk when your SIEM team owns the work
Pick Send-Shield if
Best for teams that want a managed DMARC rollout
It handled the primary domain and marketing subdomain cleanly, with visible domain status and enough report detail to plan policy movement.
Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender were easier to classify than in the Splunk add-on.
The forwarded mail SPF failure and visible-from mismatch were explained in DMARC terms that a security owner could hand to DNS or messaging teams.
From £19.99 / month
Pick Splunk TA-DMARC add-on if
Best for Splunk-heavy teams that want raw DMARC data in existing searches
It ingested aggregate reports from our mailbox path and made the spoof sample searchable alongside other authentication events.
The Microsoft 365 and Google Workspace traffic was usable once we tuned searches, field mapping, and source lookups.
The parked domain was easy to monitor for unexpected reports, but owner classification and next actions needed custom work.

Consider Suped if
The third option is guided fixes, hosted records, and simpler ownership
Look for guided fixes that turn SPF, DKIM, and DMARC findings into next steps for the person who owns the sender.
Automated issue detection should separate spoofing, forwarding noise, broken alignment, and unknown sources without manual search tuning.
Published starter pricing matters when a team needs to budget before a sales conversation.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric based on the same 90-day setup, authentication cases, sender mix, and operating tasks. Higher is better in every row.
Send-Shield scores higher for managed DMARC work, while Splunk scores higher for operator control.
Send-Shield moved faster through onboarding, sender review, and policy planning because it was built around DMARC reporting rather than generic event ingestion. Splunk TA-DMARC add-on exposed useful raw data, but the unknown sender, forwarded SPF failure, and visible-from mismatch all needed saved searches, lookup maintenance, and operator judgement. Splunk scored well where existing Splunk infrastructure mattered, especially alert routing and API access, but unsupported hosted records and manual ownership workflows limited its DMARC enforcement score.

Feature set
Managed depth vs raw control
Send-Shield has the stronger DMARC feature set. Splunk has the stronger data plumbing.
Send-Shield gave us more of the DMARC workflow out of the box: source review, policy guidance, drilldowns, and clearer handling of the spoof sample. Splunk TA-DMARC add-on was useful when we wanted DMARC reports inside existing Splunk searches, but it left classification and remediation to the operator. For buying criteria, guided fixes and automated issue detection matter when the person reading the report is not the person who owns every sender.
Send-Shield
Microsoft 365 classified quickly
Mailchimp separated cleanly
Subdomain DKIM surfaced
Splunk TA-DMARC add-on
Raw spoof searches worked
Google Workspace needed tuning
SendGrid labels stayed manual
Send-Shield accepted reports for the primary domain, marketing subdomain, and parked domain without needing us to design dashboards. Microsoft 365 and Google Workspace were recognized quickly, SendGrid and Mailchimp were separated from direct corporate traffic, and the unknown support desk sender was visible enough to classify after a short review. The DKIM pass on a subdomain still required a policy decision, but the interface kept the alignment issue tied to the affected sender rather than burying it in raw XML.
Splunk TA-DMARC add-on gave us control over ingestion, parsing, and searching, which was useful for the unauthorized spoof sample and for joining DMARC events with other authentication logs. Microsoft 365 and Google Workspace became clear after lookup tuning, but SendGrid and Mailchimp needed custom source labels, and the unknown sender sat as an investigation task rather than a guided workflow. The visible-from mismatch was easy to find once we had the right search, but the product did not tell us what to fix.
User experience
Guidance vs control
Send-Shield is easier for DMARC owners. Splunk suits teams that prefer searches over guided workflows.
Send-Shield was faster to operate because the product showed domain status, sender classification, and authentication outcomes in a DMARC-specific flow. Splunk TA-DMARC add-on felt familiar for SIEM operators, but each buyer-facing answer depended on a search, lookup, or dashboard we maintained.
Send-Shield
Three domains onboarded cleanly
Unknown sender easier to classify
Forwarding failure explained clearly
Splunk TA-DMARC add-on
Mailbox setup took tuning
Unknown sender required searches
Forwarding needed translation
Onboarding the three test domains in Send-Shield was straightforward: the primary domain moved into monitoring first, the marketing subdomain followed, and the parked domain made unauthorized activity easy to spot. Finding the unknown sender took one pass through source views and report drilldowns. The forwarded mail SPF failure was explained as a forwarding pattern rather than a sender outage, which reduced the chance of changing the wrong SPF record.
Splunk TA-DMARC add-on needed more setup discipline. We had to confirm mailbox collection, parsing, field extraction, and dashboard behavior before the three domains were useful. The unknown sender was findable through searches, but it did not become an owned remediation task without a separate process. The forwarded mail SPF failure was visible in events, but explaining it to a messaging team required translating Splunk fields back into DMARC language.
Support
Setup help vs self managed
Send-Shield has the clearer support path. Splunk depends on internal ownership.
Send-Shield fit the kind of DMARC project where DNS, security, and marketing teams need handoff notes and escalation routes. Splunk TA-DMARC add-on was archived and marked not supported, so the practical support model was internal Splunk administration and community knowledge.
Send-Shield
DNS handoff was clearer
Support tiers are visible
Escalation path more practical
Splunk TA-DMARC add-on
Archived add-on, not supported
DNS work stayed internal
Escalation depended on Splunk team
During setup, Send-Shield gave us a cleaner path for DNS handoff: publish the reporting record, confirm mail flow, classify sources, then plan policy movement. The paid tiers publicly distinguish basic email support, meeting support, and premium 24/7 support, which made escalation expectations easier to set. Enterprise onboarding was not fully visible in public pricing, but the managed implementation language matched the handoff needs we saw on the corporate domain.
Splunk TA-DMARC add-on did not provide a product support route during our test. DNS setup was our responsibility, mailbox polling was our responsibility, and any parsing or dashboard issue became a Splunk owner task. That can work in a mature security operations team, but it creates a support gap for SMBs or MSPs that need vendor-backed DMARC guidance.
Suitability
Buyer fit
Send-Shield fits managed DMARC buyers. Splunk fits security operators with existing infrastructure.
Send-Shield is the cleaner fit when a business needs DMARC enforcement progress and supportable handoffs. Splunk TA-DMARC add-on is sensible only when the buyer already has Splunk capacity and people ready to own parsing, searches, and reporting. MSP workflows and alert quality should be buying criteria here, because account separation, client grouping, recurring reports, and noisy alerts become weekly operating costs.
Send-Shield
Good SMB policy workflow
Domain grouping was workable
MSP separation only partial
Splunk TA-DMARC add-on
Strong for Splunk operators
Client reporting needs design
Enterprise SIEM fit only
Send-Shield suited the corporate and SMB-style parts of our test because it kept each domain readable and made recurring status easier to explain. Account separation was not as mature as a dedicated MSP workflow, but domain grouping and handoff notes were workable for a small portfolio. For enterprise teams, its stronger fit is managed implementation, reporting, and policy movement rather than custom SIEM analytics.
Splunk TA-DMARC add-on suited an operator-led environment. Account separation, client grouping, and recurring reporting were possible through Splunk indexes, dashboards, scheduled searches, and role design, but none of that was DMARC-specific out of the box. For MSPs, that flexibility helps only if they already maintain repeatable Splunk patterns and can turn findings into client-ready handoff notes.
What each tool feels like after 90 days of real use
Send-Shield
A managed DMARC workflow for teams that want enforcement progress
After 90 days, Send-Shield felt like a practical DMARC project tool rather than a raw reporting collector. The primary domain and marketing subdomain were easy to compare, the parked domain exposed the spoof sample clearly, and Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender were readable enough for owner handoff.
The product was less compelling where we wanted broader hosted email authentication controls. SPF flattening, hosted SPF, and hosted MTA-STS were not part of the tested workflow, so DNS work still needed a separate owner. Pricing was understandable at the entry tiers, but domain caps and message limits mean growth planning matters.
Where it wins
Clear sender review for approved services.
Helpful explanations for forwarding failures.
More practical DNS handoff than Splunk.
Published entry pricing and trial.
Where it lags
No tested hosted SPF workflow.
No tested hosted MTA-STS workflow.
MSP account separation felt limited.
Message and domain caps scale quickly.

Splunk TA-DMARC add-on
A self-managed collector for teams that already run Splunk
After 90 days, Splunk TA-DMARC add-on felt useful when the job was getting DMARC XML into Splunk and searching it with other security data. The spoof sample was easy to investigate after ingestion, and the parked domain worked well as a low-noise signal for unauthorized mail.
The daily friction came from turning events into a DMARC operating process. The unknown sender needed custom classification, the visible-from mismatch needed a saved search and explanation, and the forwarded SPF failure required someone who understood both Splunk fields and DMARC alignment. The add-on itself had no public DMARC pricing tiers, but the required Splunk environment determines the real cost.
Where it wins
Strong fit for Splunk searches.
Self-managed deployment control.
Useful for spoof investigations.
No separate add-on license found.
Where it lags
Archived and marked not supported.
Sender classification stayed manual.
No hosted authentication records.
DMARC reporting required custom dashboards.

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Hosted records reduce DNS handoff work
Send-Shield gave us useful DNS guidance, but SPF flattening, hosted SPF, and hosted MTA-STS were not part of the tested workflow. Suped's product can centralize those hosted records so authentication fixes do not stall between security and DNS owners.
Automated classification cuts Splunk upkeep
Splunk TA-DMARC add-on made the unknown sender searchable, but classification, owner assignment, and next steps stayed manual. Suped's product is built to identify sending sources and separate forwarding noise, spoofing, and alignment failures without maintaining custom searches.
MSP workflows need repeatable handoffs
Send-Shield was workable for a small portfolio and Splunk was flexible with custom roles, but both required extra process for recurring client reports and handoff notes. Suped's product supports MSP-style domain management, alerts, and reporting as first-order workflows.
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.
