Over 1,200 organizations across healthcare, finance, retail, and government use OnDMARC, including Domino's, Capgemini, ZoomInfo, Athletic Greens, and Wise. DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email security standard that prevents attackers from spoofing a domain. Getting to p=reject, the enforcement level where domain spoofing is actually blocked, typically takes security teams months without dedicated tooling. OnDMARC cuts that to 6-8 weeks through guided configuration, automated DNS record management, and real-time visibility into authentication status across sending services. Reports give security and deliverability teams a clear picture of which services are sending on behalf of their domains, what's passing authentication, and what needs to be fixed. OnDMARC covers the full range of email authentication protocols: DMARC, DKIM, SPF, MTA-STS, and BIMI. Record updates are automated, removing the need for manual DNS edits and reducing the chance of misconfiguration. Key capabilities - Fast path to enforcement. Guided configuration and automated record updates help security teams reach p=reject in 6-8 weeks. - Investigate. An audit tool for inspecting sending sources, identifying misconfigurations, and tracing authentication failures back to their source. - Protocol automation. Ongoing management of DMARC, DKIM, SPF, MTA-STS, and BIMI without manual DNS intervention. - BIMI and VMC provisioning. Supports Brand Indicators for Message Identification setup and Verified Mark Certificate provisioning for inbox logo display. - DNS Guardian. Monitors DNS records for misconfigurations such as dangling CNAMEs that can expose domains to takeover and SubdoMailing-style attacks. - Red Sift Radar. An AI-assisted analysis layer that surfaces contextual recommendations, helping teams identify and fix email misconfigurations faster. OnDMARC is used by security teams, IT administrators, and email deliverability professionals across organizations of all sizes, including enterprises and regulated industries where email authentication compliance is part of broader security requirements. * * * Product Website Red Sift OnDMARC Seller [Red Sift](https://www.g2.com/sellers/red-sift) Discussions [Red Sift OnDMARC Community](https://www.g2.com/products/red-sift-red-sift-ondmarc/discuss) Languages Supported English, French Solution Type Best-of-Breed Show More ## Value at a Glance Averages based on real user reviews. ### Time to Implement 2 months [ View More Pricing Information ](https://www.g2.com/products/red-sift-red-sift-ondmarc/pricing) ## Red Sift OnDMARC Integrations (1) What do users say about integrations?

Red Sift OnDMARC offers a clean, intuitive dashboard that makes it easy to monitor and manage email authentication protocols like SPF, DKIM, and DMARC.

What do you dislike about Red Sift OnDMARC? While the platform performs well overall, the initial setup process can feel overwhelming for users unfamiliar with DNS changes or email authentication concepts. Also, some integrations with third-party mail providers could be smoother or more automated. Reporting could include more export and customization options, especially for larger organizations needing deeper analytics. Review collected by and hosted on G2.com. What problems is Red Sift OnDMARC solving and how is that benefiting you? Red Sift OnDMARC helps us address the critical challenge of email spoofing and phishing by ensuring our domain is properly authenticated using DMARC, SPF, and DKIM protocols. Before implementation, we had limited visibility into who was sending emails on behalf of our domain, leading to security risks and potential brand damage. OnDMARC provided clear insights and actionable guidance to move from a "none" policy to full "reject" enforcement. As a result, we've significantly reduced the risk of impersonation attacks, improved email deliverability, and strengthened our overall email security posture.

Infrastructure Security Engineer Mid-Market (51-1000 emp.) 4/14/2025 "Makes implementing DMARC simple" 5/5 What do you like best about Red Sift OnDMARC? Using Red Sift we've been able to go from a DMARC none policy to DMARC reject in a matter of months. Not only does the product make visualising DMARC reports a breeze, but using Dynamic Services it makes DNS changes to DMARC, SPF, DKIM and MTA-STS incredibly simple. Dynamic services was also easy to integrate with our DNS provider. Before using OnDMARC we didn't have the visibility required to properly implement email security. We're now in DMARC reject, MTA-STS enforce and have been able to tidy up our DNS records. We also use some of their other tools frequently to monitor certificates, which has allowed us to be more proactive. The Red Sift team have been incredibly helpful in assisting with the implementation of OnDMARC. I rate their support highly. I'd have no problem recommending this to anyone looking to implement DMARC, SPF Flattening, MTA-STS or BIMI. Review collected by and hosted on G2.com. What do you dislike about Red Sift OnDMARC?

Platform can support adding multiple domains (thousands if required) to manage DMARC compliance. They helpfully provide an email address you're able to mail to check for compliance on a domain, this is really useful when struggling to understand if there is issues with the configuration. Their support is really good and feels very attentive and quick. It was also very easy to identify which services were sending on the domain, as they list these out for each domain. I really like the ability to make use of their DNS hosting for specific domains as this helps with limits sometimes hit with SPF records. The tool is easy to implement just by adding DMARC records to the domain which switch on reporting on the domain. We use the tool constantly to monitor our domains. Review collected by and hosted on G2.com. What do you dislike about Red Sift OnDMARC? Initially their ability to monitor when DNS changes were made that affected DMARC compliance was a challenge, this has since been improved and you can now setup monitoring to get visibility of this.
