Last reviewed: March 29, 2026
This comparison is based on publicly available product positioning and our current understanding at the time of writing. Product capabilities and packaging can change.
Overview & positioning
Red Sift OnDMARC is one module within Red Sift's broader digital resilience platform, which also includes OnBRAND (BIMI), OnINBOX (phishing detection), and certificate monitoring. OnDMARC focuses on DMARC reporting and automated configuration, with strong ties to the wider Red Sift ecosystem.
SpoofSentry is purpose-built for email authentication enforcement. Instead of being one piece of a larger brand-protection suite, it goes deep on domain security scoring, dangling DNS detection, enforcement simulation, and MSP/MSSP multi-tenant workflows. The focus is on getting organisations from monitoring to enforcement as quickly and safely as possible.
Key differences
- Platform scope: Red Sift bundles DMARC with brand protection, certificate monitoring, and phishing detection. SpoofSentry focuses entirely on email authentication and domain security, going deeper in that specific domain.
- Enforcement simulation: SpoofSentry lets you simulate the impact of moving to p=quarantine or p=reject before making DNS changes. Red Sift OnDMARC provides automated configuration suggestions but not the same enforcement preview capability.
- Dangling DNS detection: SpoofSentry continuously scans for orphaned CNAME, MX, and NS records that could enable subdomain takeover. This is outside the scope of OnDMARC.
- MSP/MSSP-first: SpoofSentry includes native multi-tenant management, PSA integrations, and white-label portals for service providers. Red Sift supports partners but its product is primarily oriented toward direct enterprise customers.
- Pricing model: SpoofSentry offers a free tier and transparent pricing. Red Sift typically uses enterprise sales-led pricing that requires contacting their team.

Pricing comparison
Red Sift uses enterprise sales-led pricing. OnDMARC is typically sold as part of a bundle with other Red Sift products, which can be cost-effective if you need the full suite but expensive if you only need DMARC.
SpoofSentry offers a free tier for core tools and transparent per-domain pricing that scales with usage. MSP/MSSP volume pricing makes it practical for service providers managing large domain portfolios without committing to a broader platform bundle.

Frequently asked questions
Can SpoofSentry replace the entire Red Sift suite?
SpoofSentry replaces OnDMARC for email authentication monitoring and enforcement and goes further with enforcement simulation and dangling DNS detection. However, it does not cover Red Sift's certificate monitoring or phishing detection products. If you need those capabilities, you would use separate tools alongside SpoofSentry.
Is Red Sift OnDMARC better for large enterprises?
Red Sift can be a good fit for enterprises that want a single vendor for brand protection, BIMI, and DMARC. However, SpoofSentry serves enterprises equally well for email authentication specifically, and its enforcement simulation and domain security scoring often provide more actionable insights.
How does migration from Red Sift OnDMARC work?
Both platforms read standard DMARC aggregate reports via DNS. You can run SpoofSentry in parallel with OnDMARC during migration without any DNS changes. Once you are confident in SpoofSentry, simply update your DMARC RUA tag to point to SpoofSentry's reporting address.
Does SpoofSentry support BIMI like Red Sift OnBRAND?
Yes. SpoofSentry includes BIMI record management and validation as part of its email authentication platform. Red Sift offers this through a separate OnBRAND product, which may require an additional purchase.
