Red Sift OnDMARC
DMARC management platform with Dynamic SPF and AI-powered email authentication automation.
Red Sift OnDMARC Overview
What it does
Red Sift OnDMARC is an email authentication platform that enables organizations to implement DMARC, SPF, DKIM, BIMI, and MTA-STS in 6-8 weeks through automated configuration and management. The platform's Dynamic SPF feature solves the 10-DNS-lookup limit without macros by flattening records at query time, while Dynamic Services allows management of all authentication records from OnDMARC's interface without requiring ongoing DNS access, eliminating configuration errors and accelerating deployment.
How it works
OnDMARC includes DNS Guardian to detect and block SubdoMailing attacks and domain takeovers that bypass DMARC, Red Sift Radar LLM assistant for 10x faster issue diagnosis, and integrated Verified Mark Certificate (VMC) provisioning through partnership with Entrust for BIMI implementation. The platform provides forensic reporting, real-time monitoring, and one-click integrations with SIEM, SOAR, and XDR platforms including Cisco Security, Microsoft, and cloud providers.
Credentials and traction
Red Sift holds ISO 27001 certification and a SOC 2 Type II attestation, with independent annual reviews of its security processes. OnDMARC serves over 1,200 organizations, including Domino's, Capgemini, ZoomInfo, TUI, Wise, Save the Children, and ITV.
