Red Sift operates a multi-product B2B SaaS model built around a shared cloud platform. It creates value by continuously monitoring domains, email infrastructure and public-facing assets, surfacing risks, automating investigation and guiding remediation. The platform architecture supports modular adoption, allowing customers to start with a specific use case such as DMARC enforcement and expand into adjacent products such as brand protection or DNS risk monitoring.
