Red Sift and GMO GlobalSign partner to block phishing and build trust in the inbox

From today, Red Sift OnDMARC is now available directly through GMO GlobalSign, one of the world’s most deeply-rooted certificate authorities. GlobalSign customers can procure OnDMARC to achieve DMARC enforcement, which unlocks Brand Indicators for Message Identification (BIMI) through a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC) provided by GlobalSign.

For organizations that want both email security and verified brand visibility in the inbox, this creates a single path from authentication to brand display, all through one trusted provider.

Until now, organizations purchasing a VMC or CMC from GMO GlobalSign needed to source DMARC tooling separately. That often meant coordinating across vendors, adding additional admin to already busy security teams.

With OnDMARC available through GMO GlobalSign, customers get a streamlined pathway to DMARC enforcement. From there, they can apply for and set up a VMC or CMC, unlock BIMI, and host all DNS records and images through our Dynamic Services. No switching between platforms, no gaps between buying a certificate and being ready to use it.

BIMI displays your verified brand logo next to messages in recipients’ inboxes, replacing generic initials or blank avatars. It turns every legitimate email into a brand impression. Not only do organizations with BIMI see a 39% increase in email open rates, a VMC adds a blue verification tick on top of the logo, confirming your domain has been authenticated and your logo is a registered trademark. But to qualify for a VMC or CMC, you need DMARC at the enforcement level (p=quarantine or p=reject). That’s the prerequisite many organizations struggle with, and it’s exactly what OnDMARC is built to solve.

This makes BIMI one of the rare initiatives where security and marketing goals genuinely align. Instead of competing for budget or priority, both teams benefit from the same implementation path. OnDMARC gets you to enforcement quickly and safely, and once you’re there, BIMI and either a VMC or CMC become a natural next step that turns your email authentication investment into a visible, measurable brand asset.

Getting to DMARC enforcement is where most organizations hit friction. OnDMARC keeps it simple:

• Automated discovery of all domains and subdomains sending emails on your behalf
• Dynamic SPF to solve the common 10 DNS lookup limit
• Red Sift Radar, an LLM-powered assistant that flags misconfigurations, authentication issues, and unusual activity in real time
• DNS Guardian to overcome threats imposed by Subdomailing attacks
• BIMI and MTA-STS support built in, so there’s no need to switch tools once enforcement is reached

Red Sift OnDMARC is trusted by over 1,200 organizations, holds a 5.0/5 rating on Gartner Peer Insights, and is rated 4.8/5 on G2.

DMARC enforcement shouldn’t be the thing standing between your brand and the inbox. With Red Sift OnDMARC now available through GMO GlobalSign, customers get a direct path from email authentication to BIMI and VMC, without the complexity of managing multiple vendors.

For GlobalSign customers ready to take advantage of this new partnership, the easiest way to check if you’re BIMI-ready is to use Red Sift’s free BIMI checker. In just a few seconds, you’ll get a full breakdown of your email authentication setup, DMARC policy level, and where you’re ready to progress to BIMI with actionable next steps.
