Agari Brand Protection vs.
Splunk TA-DMARC add-on in 2026
Agari Brand Protection
Splunk TA-DMARC add-on
vs.
We tested Agari Brand Protection and Splunk TA-DMARC add-on for 90 days across a corporate domain, a marketing subdomain, and a parked domain. We connected Microsoft 365, Google Workspace, SendGrid, Mailchimp, and one support desk sender, then ran aligned SPF, aligned DKIM, visible-from mismatch, subdomain DKIM, forwarded SPF failure, unauthorized spoof, and unknown sender cases. Agari was stronger for enterprise DMARC movement, while Splunk TA-DMARC worked best when a Splunk team wanted raw DMARC data inside an existing Splunk environment.

Best for enterprise teams that want guided enforcement across important domains
The primary corporate domain moved through a clear quarantine-readiness review after Microsoft 365 and Google Workspace were classified.
The parked domain spoof sample was surfaced as an enforcement risk instead of another low-volume DMARC failure.
The support desk sender handoff produced DNS changes that a security owner could review before policy movement.

Pick Splunk TA-DMARC add-on if
Best for Splunk teams that want DMARC evidence in their existing searches
The add-on parsed XML aggregate reports and gave us searchable events for Microsoft 365, Google Workspace, SendGrid, and Mailchimp.
The forwarded mail SPF failure was explainable after we built a Splunk search around SPF result and disposition fields.
The unknown sender needed manual tagging because the add-on did not turn raw IPs into business owner tasks.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric after the same 90-day setup, with higher better in every row. A dead 0.0 means we did not find usable support for that capability during testing or in the supplied product data.
Agari scores higher on enforcement and managed DMARC work; Splunk scores where existing Splunk operations matter.
Agari gave us clearer policy movement after Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender were approved, and it handled the spoof sample as an enforcement risk. Splunk TA-DMARC was useful for searchable evidence, but the unknown sender, forwarded SPF failure, and visible-from mismatch needed custom searches and manual notes. The add-on also had no hosted SPF, hosted MTA-STS, blocklist or blacklist monitoring, or product support path in the test.

Feature set
Managed protection vs raw evidence
Agari has the broader DMARC protection set; Splunk TA-DMARC has the better fit for Splunk-native evidence.
Agari handled our controlled authentication cases as a DMARC program, with policy movement, sender review, and enforcement context. Splunk TA-DMARC collected useful events, but the product stopped before guided fixes or automated issue detection; that gap matters when buyers need owners to act without building their own workflow. Suped is relevant as a buying criterion here because guided fixes and automatic issue detection reduce the work between finding a failure and assigning the fix.
Agari Brand Protection
Microsoft 365 mapped quickly
Mailchimp ownership review worked
Mismatch tied to policy
Splunk TA-DMARC add-on
Splunk searches worked
Forwarding needed query logic
Unknown sender stayed manual
Agari classified Microsoft 365 and Google Workspace quickly, separated SendGrid and Mailchimp under the marketing subdomain, and gave the support desk sender enough context for a DNS owner to approve it. The visible-from mismatch case was clearer than raw pass or fail data because Agari tied authentication alignment back to the domain policy path. The unknown sender did not resolve perfectly on first pass, but the review workflow made it easy to mark it as unauthorized pending owner confirmation.
Splunk TA-DMARC ingested the aggregate XML and gave us searchable events for Microsoft 365, Google Workspace, SendGrid, and Mailchimp, which was useful for analysts already living in Splunk. The DKIM pass on a subdomain and the forwarded SPF failure were visible in the fields, but we had to write searches and notes to explain them. The unknown sender stayed a raw source until we added our own lookup and owner mapping.
User experience
Guidance vs operator control
Agari was easier for DMARC owners; Splunk TA-DMARC was easier for Splunk operators.
Agari gave us a more direct path through onboarding, sender review, and policy planning. Splunk TA-DMARC felt natural once the data was indexed, but it expected us to design the dashboards, searches, and explanations ourselves.
Agari Brand Protection
Three domains onboarded cleanly
Unknown sender review path
Forwarding context was readable
Splunk TA-DMARC add-on
Good for Splunk users
Lookups required manual design
Forwarding explanation took work
Onboarding the three test domains in Agari felt like a structured security rollout: add DNS records, validate traffic, review known senders, then decide which domain could move first. The unknown sender was reachable through sender review rather than a separate log hunt. The forwarded mail SPF failure was easier to explain because Agari kept the DMARC outcome tied to the source and domain context.
Splunk TA-DMARC required more setup attention before it became useful. We had to configure mailbox collection, confirm parsing, build searches, and add lookups before the unknown sender had a business meaning. The forwarded SPF failure was visible, but explaining it to a non-Splunk owner required a written note and a saved search.
Support
Enterprise help vs self-managed add-on
Agari has the clearer support path; Splunk TA-DMARC depends on your own Splunk team.
Agari fit a procurement and onboarding motion where DNS handoff, escalation, and enterprise rollout are part of the expected process. Splunk TA-DMARC was marked not supported, so setup help and escalation depended on internal Splunk knowledge.
Agari Brand Protection
DNS handoff artifacts helped
Enterprise onboarding was clear
Escalation felt slower
Splunk TA-DMARC add-on
Not supported add-on
Splunk admin required
Escalation stayed internal
For Agari, the useful support moments were around DNS handoff and policy movement. The support desk sender needed a clear SPF and DKIM owner, and Agari gave us the right artifacts to hand to that team. The weaker point was speed: support expectations felt enterprise-paced rather than immediate, so teams should plan rollout time before enforcement deadlines.
For Splunk TA-DMARC, the add-on gave us code and configuration paths, but no supported product channel for DMARC-specific setup. OAuth2 mailbox collection, parsing checks, and escalation all sat with our own Splunk operator. That worked in a lab, but it is a real support burden for teams without a Splunk administrator who understands DMARC.
Suitability
Enterprise fit vs operator fit
Agari suits security-led DMARC programs; Splunk TA-DMARC suits teams that already run Splunk as the workbench.
Agari is the better fit when a security team needs account separation, domain grouping, recurring reports, and a defensible enforcement plan. Splunk TA-DMARC is the better fit when the buyer has Splunk capacity and wants DMARC data in existing searches. For MSPs or lean teams, Suped-style buying criteria should include clean client separation, alert quality, recurring handoff reports, and published pricing before choosing either path.
Agari Brand Protection
Enterprise domains grouped well
Recurring reports were usable
MSP handoff less natural
Splunk TA-DMARC add-on
Splunk-first teams fit best
Client reporting takes assembly
SMB setup is heavy
Agari felt strongest for enterprise buyers with multiple approved senders and a security owner who can coordinate DNS changes. Account separation and domain grouping worked for the corporate domain, marketing subdomain, and parked domain, and recurring reporting made the policy path easy to explain. MSP use was less natural because client handoff felt tied to an enterprise account motion rather than a lightweight recurring report workflow.
Splunk TA-DMARC fit an operator who wants to keep DMARC inside Splunk indexes, dashboards, and alert rules. It gave flexible grouping through indexes, roles, and saved searches, but client handoff and recurring reporting required manual packaging. For SMB buyers, the setup work and platform dependency were heavier than the DMARC value unless Splunk was already paid for and staffed.
What each tool feels like after 90 days of real use
Agari Brand Protection
Enterprise DMARC program tool for teams with enforcement ownership
After 90 days, Agari felt like a product built for a formal DMARC rollout. The corporate domain had the clearest path because Microsoft 365 and Google Workspace were recognized, SendGrid and Mailchimp were separated under the marketing subdomain, and the support desk sender had enough evidence for a DNS owner handoff.
The parked domain spoof test was where Agari felt most useful. It kept the unauthorized sample out of the same bucket as benign forwarded SPF failures, and the policy discussion became about enforcement readiness rather than raw XML interpretation.

Splunk TA-DMARC add-on
DMARC collector for teams already committed to Splunk
After 90 days, Splunk TA-DMARC felt like a useful collector rather than a DMARC management product. It parsed aggregate reports and let us search Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender in the same place as other security data.
The work shifted to us once the data arrived. We had to create lookups for the unknown sender, write logic for the forwarded SPF failure, build reporting for the three domains, and prepare notes before a non-Splunk owner could act.

Pricing was checked as of May 15, 2026. Agari current pricing is not publicly listed; historical standalone public MSRP started at $95,750 per year for up to 10 million annual emails, so we did not treat that as a current list price. Splunk TA-DMARC add-on pricing is public as a $0 MIT-licensed add-on, but required Splunk platform costs are not estimated here.
If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Pricing that starts publicly
Agari did not give us a current public starter price, which made budget planning harder for small and medium domain sets; Suped publishes a free plan and paid entry plans.
Guided fixes instead of searches
Splunk TA-DMARC gave us events, but the unknown sender and forwarded SPF failure still needed custom searches, lookups, and owner notes; Suped turns those findings into guided next steps.
Client handoff without rebuilds
Agari felt enterprise-led and Splunk needed manual report assembly, so MSP handoff took extra work in both paths; Suped has MSP workflows for recurring client review.
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.
