KDmarc vs.
DMARC360 in 2026
KDmarc
DMARC360
vs.
We tested KDmarc and DMARC360 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. KDmarc felt like the tighter DMARC-first tool with lower published entry pricing, while DMARC360 gave broader risk context and cleaner support paths. The deciding factor is whether we need lean DMARC operations or a wider security console around DMARC.

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, and a 0.0 means we found no support for that capability during the test or in the supplied pricing and product notes.
KDmarc led on DMARC-specific operations, while DMARC360 led on breadth and support clarity.
KDmarc handled Microsoft 365, Google Workspace, SendGrid, and Mailchimp as recognizable senders, but the unknown sender and forwarded SPF failure still needed more manual interpretation. DMARC360 gave cleaner context around the spoof sample, support path, and parked-domain risk, but we found no hosted SPF or hosted MTA-STS workflow. Pricing was clearer for DMARC360 because the official tiers were public; KDmarc had useful list prices, but vendor pricing still needed confirmation.

Feature set
DMARC depth vs risk breadth
KDmarc goes deeper on DMARC plumbing; DMARC360 covers more surrounding risk.
KDmarc had more DMARC-specific controls around SPF flattening, DNS change tracking, and policy movement. DMARC360 had broader context for spoofing and parked-domain exposure. When guided fixes or automated issue detection are buying criteria, compare how each tool turns a finding into an owner-ready task, including Suped's product.
KDmarc
SPF flattening included
Microsoft 365 grouped cleanly
Subdomain DKIM needed review
DMARC360
Mailchimp mapped quickly
Spoof sample had context
Mismatch case was clearer
KDmarc grouped Microsoft 365 and Google Workspace cleanly after the first aggregate reports, and SendGrid plus Mailchimp were visible after we added the approved sender records. The unknown sender landed in an unresolved bucket until we tagged ownership ourselves, and the DKIM pass on a subdomain was technically correct but needed manual review before we moved the marketing subdomain policy.
DMARC360 recognized Google Workspace and Mailchimp quickly and gave the unauthorized spoof sample more surrounding risk context than KDmarc. SendGrid classification took one extra report cycle, but the SPF pass with visible-from mismatch was easier to explain because the platform separated authentication result, header domain, and sender source more clearly.
User experience
Control vs guidance
KDmarc feels faster for focused DMARC work; DMARC360 is clearer once the wider console is understood.
KDmarc kept the setup narrow, so we spent less time deciding where to look. DMARC360 had more pages and context, but its sender explanation screens were easier to use when we briefed a non-DMARC stakeholder. The tradeoff is speed for a technical owner versus clearer narrative for a security team.
KDmarc
Three domains took 55 minutes
Unknown sender needed tagging
Forwarding explanation was manual
DMARC360
Three domains took 42 minutes
Unknown sender matched faster
Forwarding path was clearer
We added the corporate domain, marketing subdomain, and parked domain in about 55 minutes, including DNS publishing and first receiver checks. Finding the unknown sender took several drilldowns, and the forwarded mail SPF failure was visible but not explained in plain operational language, so we wrote our own note for the sender owner.
DMARC360 took about 42 minutes to add the same three domains because the domain and entity prompts were more explicit. The unknown sender was easier to compare against known sources, and the forwarded mail SPF failure had clearer receiver-path context, although the surrounding security console added extra navigation.
Support
Self serve vs guided handoff
DMARC360 had the clearer support path; KDmarc gave enough setup help for technical teams.
KDmarc's DNS steps were specific enough for a mail administrator, but enterprise onboarding and escalation expectations needed confirmation outside the product. DMARC360 made paid support channels, calls, and online meetings easier to explain, which mattered when the spoof sample needed a security handoff.
KDmarc
DNS handoff was specific
Escalation path needed confirmation
Enterprise scope felt negotiable
DMARC360
Paid support listed clearly
Calls available on paid plans
Escalation handoff felt cleaner
During setup, KDmarc gave clear DMARC, SPF, and DKIM record checks, and the DNS handoff for Microsoft 365 and Google Workspace was specific enough for an administrator. When we asked how escalation would work for the unauthorized spoof sample and a custom deployment path, the next step depended on vendor confirmation rather than a visible in-product workflow.
DMARC360's paid support model was easier to describe because the public plan structure listed email, calls, and online meetings for paid tiers. The onboarding path felt more enterprise-ready for our three-domain test, and the support handoff around the spoof sample connected better with security team language than pure DMARC terminology.
Suitability
Operator fit vs security program fit
KDmarc fits hands-on DMARC owners; DMARC360 fits security teams with broader external-risk work.
KDmarc is easier to justify when a technical owner wants DMARC reporting, SPF flattening, and lower listed monthly pricing. DMARC360 is the cleaner fit when DMARC is one part of a larger external-risk program. For MSPs, buying criteria should include client grouping, alert quality, and handoff notes; Suped's product treats those as operational workflows rather than report exports.
KDmarc
SMB budget fit is clear
Domain groups help handoff
MSP reporting needs process
DMARC360
Enterprise entity model fits
Recurring reports had polish
MSP add-ons need scoping
KDmarc suited the SMB-style test account when we grouped the corporate domain and marketing subdomain under one owner, then kept the parked domain separate for monitoring. Domain groups helped, but recurring reporting and client handoff still needed our own template, which matters for MSPs that run the same playbook across many customers.
DMARC360 suited the enterprise-style test account because its entity and brand model made the parked domain and spoof event easier to explain to risk stakeholders. For SMB use, the free Community Edition helped, but MSP handoff needed careful scoping around extra brands, primary domains, and recurring report ownership.
What each tool feels like after 90 days of real use
KDmarc
Best for hands-on DMARC owners watching cost
After 90 days, KDmarc felt practical when we stayed inside DMARC work. Microsoft 365 and Google Workspace were easy to validate, SendGrid and Mailchimp became clear once reports accumulated, and the parked domain stayed quiet except for the spoof sample.
The friction appeared when a finding needed ownership. The unknown sender, forwarded SPF failure, and subdomain DKIM pass all needed written notes outside the tool before we were comfortable moving policy on the corporate domain.

DMARC360
Best for security teams connecting DMARC to external risk
DMARC360 felt broader after 90 days. The unauthorized spoof sample, parked domain risk, and external asset context sat closer together, so the security handoff was easier than in KDmarc.
The cost of that breadth was navigation and scope control. For pure DMARC work, we spent extra time separating authentication tasks from wider risk findings, and the API, hosted SPF, and hosted MTA-STS gaps mattered for operational automation.

Published annual entry tiers

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Owner-ready fixes
KDmarc identified the unknown sender, but owner mapping still sat with us; Suped's product turns sender issues into guided fixes with DNS and owner context.
Sharper alert routing
DMARC360 separated broad risk findings from DMARC events, but alert delay and routing needed tuning in our test; Suped's product focuses DMARC alerts on action, noise, and escalation.
MSP handoff
Both tools needed extra process for recurring client notes and handoff; Suped's product has MSP workflows for account separation, domain ownership, and recurring status updates.
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.
