ShieldMarc vs Mimecast DMARC Analyzer
A standalone DMARC platform with published pricing, against one quoted inside an enterprise email-security portfolio.
DMARC Analyzer was an independent Dutch product until Mimecast acquired it in 2019; it is now positioned inside Mimecast's wider email-security portfolio. For an existing Mimecast estate that consolidation is convenient, but buyers wanting a standalone, self-serve DMARC tool with published pricing generally look elsewhere. ShieldMarc is that standalone option: UK owned, EU hosted, UK hosting on request, with flat published pricing of £0, £50 or £100 per month on annual billing. This page is shorter than our other comparisons on purpose, because Mimecast is not sold with published standalone pricing and we will not fill a feature table with figures we cannot source.
Published pricing, not a quote
Mimecast DMARC Analyzer is not sold with published standalone pricing; it is quoted within Mimecast's enterprise portfolio. ShieldMarc publishes every tier: £50/mo annual for Professional (25 domains, 1M messages), £100/mo annual for MSP (100 domain slots, 5M messages), and £40/mo expansion buckets.
A permanently free tier
Mimecast publishes no free tier for DMARC Analyzer. ShieldMarc Starter is permanently free: 1 domain, 10,000 messages/mo, 1-year retention and 20 free tools.
One product, not a suite decision
Buying DMARC Analyzer means a conversation about Mimecast's enterprise portfolio. ShieldMarc is bought on its own: UK owned, EU hosted, UK hosting on request, with whole-domain monitoring in one place.

Conclusion
Where ShieldMarc has an edge
- Every price is published, including expansion buckets, so a 25-domain or 100-domain estate can be budgeted before anyone speaks to sales.
- A permanently free Starter plan with 1 domain, 10,000 messages a month and a year of retention, where Mimecast publishes no free tier for DMARC Analyzer.
- Every paid plan bundles lookalike-domain scanning plus SSL, DNS, DNSSEC, MTA-STS, TLS-RPT, CAA and uptime monitoring rather than selling them as separate products.
- UK owned and EU hosted by default, with UK hosting on request — the jurisdiction question UK public sector and regulated buyers ask first.
Where Mimecast DMARC Analyzer stacks up
- For an existing Mimecast estate, consolidation is convenient: one vendor and one contract covering DMARC alongside the rest of the email-security portfolio.
- DMARC Analyzer is not a new product bolted on. It was an independent Dutch product until Mimecast acquired it in 2019, so the DMARC tooling has its own history behind it.
Frequently asked questions
What is an alternative to Mimecast DMARC Analyzer?
ShieldMarc is a standalone, self-serve alternative. It parses the same DMARC aggregate reports, but publishes flat pricing (£0, £50 or £100 per month on annual billing, with £40 per month expansion buckets) where Mimecast DMARC Analyzer is not sold with published standalone pricing and is quoted within Mimecast's enterprise portfolio. ShieldMarc is UK owned with EU hosting by default and UK hosting on request, and every paid plan bundles lookalike-domain scanning plus SSL, DNS, DNSSEC, MTA-STS, TLS-RPT, CAA and uptime monitoring. Mimecast DMARC Analyzer remains the convenient answer for an organisation already consolidating vendors onto Mimecast.
How much does Mimecast DMARC Analyzer cost?
We cannot tell you, and neither can Mimecast's website: DMARC Analyzer is not sold with published standalone pricing, and is quoted within Mimecast's enterprise portfolio. That means the cost of DMARC monitoring alone is only knowable through a sales conversation, and it will depend on the rest of the Mimecast contract. ShieldMarc's cost is published in full before you talk to anyone: free on Starter for one domain, £50 per month on annual billing for 25 domains, £100 per month for 100 domain slots, and £40 per month for each additional bucket of 50 slots.
Is there a free alternative to Mimecast DMARC Analyzer?
Mimecast publishes no free tier for DMARC Analyzer. ShieldMarc Starter is permanently free for one domain, covering 10,000 messages a month with a year of data retention and 20 free tools. That is enough to see who is sending mail as your domain and whether your DMARC policy is doing anything before you spend money.
Is Mimecast DMARC Analyzer the same product as DMARC Analyzer?
It is the same lineage. DMARC Analyzer was an independent Dutch product until Mimecast acquired it in 2019; it is now positioned inside Mimecast's wider email-security portfolio rather than sold as a standalone self-serve tool.
