What Red Sift does
Red Sift is a London-headquartered cybersecurity company founded in 2015 that operates a cloud-native Digital Resilience Platform for email authentication, brand protection, certificate management, and external attack surface management. Its core product suite includes OnDMARC (automating SPF, DKIM, DMARC, BIMI, and MTA-STS configuration), Brand Trust (AI-powered lookalike domain detection scanning up to 150 million domains daily), Red Sift Certificates (public and private PKI certificate discovery), Red Sift ASM (external asset discovery, incorporating the 2022 Hardenize acquisition), and the Radar / Radar Lite LLM-based security analysis tools. The company also offers free tools (Investigate DMARC checker, SPF, BIMI, and SubdoMailing checkers) that serve as top-of-funnel product-led growth assets.
The platform is differentiated by proprietary technology including Dynamic SPF (solving the RFC 10-DNS-lookup limit without macros), DNS Guardian (continuous monitoring for SubdoMailing and dangling DNS), Social Media Monitoring (logo, face, and keyword recognition across major social platforms), and integrated VMC/CMC provisioning through its GMO GlobalSign partnership.

Red Sift operates a multi-motion GTM combining enterprise field sales (30-minute tailored demos with 24-hour PoC deployment), product-led growth through free tools and a 14-day no-credit-card trial, and an MSP partner program with multi-tenancy. Revenue is generated primarily through annual and multi-year SaaS subscriptions priced per domain count and feature tier, with tiered pricing for the MSP channel and quote-based enterprise contracts. Total disclosed funding is approximately $65 million across multiple rounds including a $54 million Series B led by Highland Europe in February 2022. The company has approximately 101-250 employees and offices in London (HQ) and Austin (US headquarters), with operating reach into Europe, North America, Asia Pacific, the Middle East, and additional EMEA and Americas markets.

Red Sift competitors and assessment
Company assessmentDirect peers
- Valimail: Pure-play DMARC and email authentication vendor offering automated SPF, DKIM, and DMARC enforcement. Closest direct competitor to Red Sift's OnDMARC, with overlapping enterprise and mid-market customers and comparable freemium + paid SaaS motion.
- dmarcian: DMARC specialist providing deployment, monitoring, and managed services for email authentication. Competes head-to-head with OnDMARC for enterprise and MSP customers, particularly in Europe where dmarcian has a strong footprint.
- EasyDMARC: DMARC, SPF, DKIM, and BIMI platform targeting SMB and MSP segments with a freemium model. Directly comparable to Red Sift's OnDMARC plus Radar Lite, with similar multi-tenant MSP capabilities and a comparable pricing tier structure.
- Agari (by Proofpoint): DMARC, anti-phishing, and brand protection platform within Proofpoint's portfolio. Directly overlaps with OnDMARC and Brand Trust, and represents the in-house competing capability Proofpoint must reconcile post-Red Sift acquisition.
Broad incumbents
- Mimecast: Large email security and resilience platform offering anti-phishing, DMARC, archiving, and secure gateway. Competes with Red Sift's OnDMARC and Brand Trust as part of a much broader enterprise security suite rather than as a DMARC specialist.
- Proofpoint: Enterprise email security leader whose reported acquisition of Red Sift would make Proofpoint both a competitor (via Agari and bundled DMARC capabilities) and the parent of Red Sift, shaping its go-to-market and product strategy.
- Cisco (Email Security / Talos): Cisco is an official reseller of Red Sift Brand Trust and offers its own IronPort and Secure Email portfolio. Comparable as an enterprise email and brand protection incumbent with the distribution leverage to push competing or Red Sift's own capabilities.
- Microsoft Defender for Office 365: Native enterprise email security suite bundled into Microsoft 365, including anti-phishing, spoof intelligence, and DMARC reporting. Represents the largest latent competitive threat if Microsoft expands native DMARC enforcement and brand protection tooling.
Emerging players
- Abnormal Security: AI-native email security platform focused on behavioral detection of BEC, phishing, and account takeover. Adjacent to Red Sift's Brand Trust in anti-impersonation, but driven by behavioral AI rather than DMARC/DNS controls.
- IRONSCALES: Email security platform combining AI-based phishing detection with DMARC and mailbox-level protection. Overlaps with Red Sift across email threat detection and brand protection use cases, particularly in mid-market and MSP channels.
