What onDMARC does
Red Sift OnDMARC is an email authentication and domain protection platform built by UK-based Red Sift (founded 2016). The product enables organizations to enforce DMARC, SPF, DKIM, MTA-STS, and BIMI standards to block email spoofing, phishing, and business email compromise (BEC) attacks, with 1,200+ organizations on the platform across enterprise and managed service provider (MSP) segments. Notable customers include ZoomInfo, Capgemini, Save the Children, TUI, Domino's, Wise, Holland & Barrett, TalkTalk, ITV, and Northmill, spanning fintech, legal, telecommunications, retail, travel, media, consulting, and non-profit verticals.
The platform's technology stack centers on proprietary mechanisms that simplify complex DNS and email authentication workflows. Dynamic SPF resolves the RFC 7208 10-DNS-lookup limit without relying on macros, flattening records at query time. DNS Guardian monitors DNS configurations to prevent SubdoMailing, dangling DNS, and CNAME takeovers. Red Sift Radar, an in-house LLM, analyzes domain security posture and identifies misconfigurations reportedly 10x faster than manual methods. The platform also integrates Verified Mark Certificate (BIMI) provisioning, with claimed outcomes of 39% improvement in email open rates and 44% improvement in brand recall.
The business operates on a hybrid SaaS subscription model with product-led growth mechanics: a 14-day free trial, free DMARC/SPF/DKIM check tools drive top-of-funnel acquisition, while dedicated enterprise sales and an MSP partner program with multi-tenant dashboards serve larger accounts. Go-to-market spans self-serve (SMB), direct enterprise sales, and channel partners, with operational geographies covering EMEA and Asia Pacific. Red Sift is privately held, with leadership comprising CEO and founder Rahul Powar and COO and co-founder Randal Pinto.

onDMARC competitors and assessment
Company assessmentBroad incumbents
- Proofpoint: Proofpoint is a leading enterprise email security incumbent offering DMARC capabilities as part of its broader secure email gateway and threat intelligence suite. It competes for the same enterprise wallets but bundles DMARC into a much larger platform.
- Microsoft (Defender for Office 365): Microsoft builds native DMARC configuration and reporting into Exchange Online Protection and Defender for Office 365. As a free or low-cost bundled feature, it represents the most significant commoditization threat to standalone DMARC vendors.
- Mimecast: Mimecast provides email security, archiving, and resilience solutions to enterprises. Its email authentication features overlap with OnDMARC's DMARC enforcement, though Mimecast sells primarily as a broader bundled suite.
- Agari (by HelpSystems / Fortra): Agari, now part of Fortra, provides email security and DMARC enforcement as part of a broader suite addressing phishing, BEC, and brand protection. It competes in the same enterprise email authentication market with a wider product portfolio.
- Cisco (Email Security / IronPort): Cisco's Email Security portfolio includes DMARC and authentication features within its broader threat defense platform. It addresses the same enterprise buyer but as part of a vastly larger security infrastructure portfolio.
Direct peers
- Sendmarc: Sendmarc offers DMARC monitoring and enforcement with strong MSP channel positioning, similar to Red Sift's MSP program. It is a direct competitor particularly in mid-market and SMB segments served through managed service providers.
- Valimail: Valimail is the most direct DMARC-focused competitor, offering automated DMARC enforcement and SPF flattening solutions to enterprises and MSPs. It competes head-to-head with OnDMARC on the same core workflow and customer profile.
- dmarcian: dmarcian provides DMARC implementation, monitoring, and managed services for organizations of all sizes, with a strong educational content focus. It targets the same DMARC enforcement buyer with overlapping PLG and consulting motions.
- EasyDMARC: EasyDMARC provides a DMARC management platform with a focus on SMB and mid-market accessibility. It competes on similar DMARC enforcement use cases with a more self-service oriented positioning.
Emerging players
- MXToolbox: MXToolbox offers email and DNS diagnostics tools including DMARC, SPF, and DKIM checks. It overlaps with OnDMARC's free-tool funnel strategy and addresses similar technical buyers, though with a less enterprise-focused product.
