Kevlarr vs.
DMARC-SRG in 2026
Kevlarr
DMARC-SRG
vs.
We ran both products for 90 days across a corporate domain, a marketing subdomain, and a parked domain. Kevlarr was the better fit for managed DMARC operations, sender classification, and client handoff; DMARC-SRG made more sense as a free self-hosted parser for teams willing to maintain the stack and interpret results themselves.

Ten dimensions, scored from 0 to 10
We scored both products against the same editorial rubric after the 90-day test. Higher is better in every row, including pricing transparency and time to enforcement.
Kevlarr leads managed enforcement, while DMARC-SRG stays strongest for self-hosted parsing
Kevlarr scored higher where the job required source resolution, policy movement, and client handoff. In the test, it named Microsoft 365 and Google Workspace traffic cleanly, separated SendGrid from Mailchimp, and handled the spoof sample without making the forwarded SPF failure look equally severe. DMARC-SRG scored well on pricing clarity for the software license and self-hosting control, but it lost ground on alerts, hosted records, source ownership, and support because those workflows had to be built around it.

Feature set
Managed depth vs parser control
Kevlarr has the stronger DMARC feature set; DMARC-SRG has tighter self-hosting control.
Kevlarr was stronger when the job was moving domains toward enforcement because it connected reports, sender names, and policy guidance in one workflow. DMARC-SRG was stronger when we only needed an owned parser and database. Suped's product is relevant when guided fixes and automated issue detection are buying criteria, because our unknown sender and forwarded SPF case both needed more than raw rows.
Kevlarr
Microsoft 365 grouped cleanly
SendGrid and Mailchimp separated
Unknown sender review queued
DMARC-SRG
Open-source parsing worked reliably
Raw SPF detail visible
Unknown sender stayed manual
Kevlarr recognized Microsoft 365 and Google Workspace as expected senders after the first full report cycle, then let us tag SendGrid and Mailchimp separately for the marketing subdomain. The unknown sender still needed human confirmation, but the workflow kept it in the review queue and showed the spoof sample as a real failure rather than the same class of noise as forwarded mail with SPF failure.
DMARC-SRG parsed the same Microsoft 365, Google Workspace, SendGrid, and Mailchimp reports into readable rows with DKIM and SPF details, which was enough for a technical admin to investigate. It did not name the unknown sender for us, and the forwarded SPF failure required manual interpretation against the DKIM result and visible From domain.
User experience
Guidance vs control
Kevlarr is easier for teams; DMARC-SRG is clearer for admins who want the database.
Kevlarr reduced the number of choices during onboarding and gave enough context for non-DMARC operators to understand the next step. DMARC-SRG was transparent, but the experience assumed comfort with mailbox ingestion, cron, database retention, and interpreting authentication rows.
Kevlarr
Three domains onboarded quickly
Unknown sender surfaced clearly
Forwarding explanation was easier
DMARC-SRG
Setup required server work
Month filters were useful
Forwarding stayed manual
Onboarding the corporate domain, marketing subdomain, and parked domain in Kevlarr took less than an hour before DNS propagation; the generated DMARC records were clear, and the parked domain was easy to keep at a stricter policy target. Finding the unknown sender took two clicks from the dashboard into the source view, and the forwarded SPF failure was labeled in a way we could explain to a support desk owner.
DMARC-SRG took longer because we had to set up the mailbox fetch, database, cron job, upload limits, and cleanup settings before the same three domains had useful history. Once running, it was fast to filter by month and reporting organization, but finding the unknown sender and explaining forwarded mail with SPF failure required reading the raw authentication detail.
Support
Hands-on help vs self-managed
Kevlarr has the support advantage; DMARC-SRG depends on internal ownership.
Kevlarr's public positioning and review pattern match what we saw: it is built for users who expect help during DNS setup and escalation. DMARC-SRG has no commercial support tier in the public materials, so the buyer needs an admin who can own hosting, mailbox ingestion, database care, and security updates.
Kevlarr
DNS handoff was clear
Escalation notes were usable
Partner setup fit was strong
DMARC-SRG
Community-style support model
Admin owns patching
Enterprise onboarding not packaged
During setup, Kevlarr's handoff model fit the work we would give to an IT partner: explain the DNS record, wait for propagation, review sources, then move the domain toward a stricter policy. It was especially useful for the support desk sender, because the path from source review to escalation notes was clearer than a spreadsheet export.
DMARC-SRG support expectations are different because the product is open source software. DNS handoff, enterprise onboarding, escalation notes, backups, and patching stayed with our team; that is fine for a technically owned deployment, but it is a poor fit when a buyer expects vendor-led enforcement planning.
Suitability
Operator fit vs ownership fit
Kevlarr suits MSP and SMB operations; DMARC-SRG suits technical teams that need self-hosting.
Kevlarr fit the recurring work of customer grouping, source review, and reporting better than DMARC-SRG. DMARC-SRG fit the narrower case where a technical team wants a free parser and owns every operational step. Suped's product belongs in the comparison when MSP workflows and alert quality are deciding criteria, because noisy alerts and weak handoff notes cost time every week.
Kevlarr
MSP grouping worked well
Recurring reports helped handoff
Enterprise pricing less clear
DMARC-SRG
Self-hosting is the fit
Client handoff is manual
No packaged onboarding
Kevlarr was strongest for MSP and SMB workflows in our test because account separation, domain grouping, and recurring reports were native enough to support a weekly customer review rhythm. For enterprise use, the missing public pricing and unclear premium boundaries made procurement harder, but the product still gave a practical path to enforcement across the corporate domain and marketing subdomain.
DMARC-SRG suited a technical SMB or internal security team that values self-hosting and does not need client access, scheduled executive reports, or account separation. For MSPs, every client handoff would need a separate process, and for enterprise buyers the lack of packaged onboarding and escalation made it hard to standardize.
What each tool feels like after 90 days of real use
Kevlarr
Best for MSPs and SMBs that want managed DMARC progress
Kevlarr felt like a working DMARC operations console after the second week. Microsoft 365 and Google Workspace were grouped cleanly, SendGrid and Mailchimp stayed visible as separate marketing sources, and the unauthorized spoof sample was prominent without turning every forwarded SPF failure into an incident.
After 90 days, the product was strongest in weekly review work: checking new sources, preparing client-facing reports, and deciding whether the corporate domain could move closer to enforcement. The parked domain was easiest to manage because it had almost no legitimate traffic, while the support desk sender needed one manual owner decision before it was treated as approved.

DMARC-SRG
Best for technical teams that want a free self-hosted parser
DMARC-SRG felt reliable once the server, mailbox ingestion, database, and cron job were in place. It parsed the corporate domain, marketing subdomain, and parked domain reports consistently, and the filters by domain, month, and reporting organization helped us inspect specific authentication cases.
After 90 days, the main cost was operator time. The unknown sender, forwarded mail with SPF failure, support desk sender approval, exports, and policy movement all required our own process outside the product, so it worked best as raw reporting infrastructure rather than a managed DMARC program.

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Turn findings into fixes
Kevlarr surfaced the unknown sender quickly, but policy movement still depended on operator judgment. Suped's product connects each source to the DNS or sender-side action needed before enforcement.
Avoid self-hosted blind spots
DMARC-SRG showed the forwarded SPF failure after manual review, but it did not produce routed alerts or owner handoff notes. Suped's product adds alert quality controls and automated issue detection.
Keep MSP work separate
Kevlarr handled account separation better than DMARC-SRG, but pricing and domain entitlements were still unclear. Suped's product has published starter pricing and MSP per-domain billing.
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.
