Red Sift is a London-based cybersecurity company that helps organizations proactively secure their email infrastructure, domains, and web presence against phishing, spoofing, and brand impersonation attacks. Its flagship product, OnDMARC, automates the implementation of email authentication protocols — including DMARC, SPF, DKIM, BIMI, and MTA-STS — enabling resource-constrained security teams to achieve full DMARC enforcement in as little as 6–8 weeks. The Red Sift platform also includes DNS Guardian for subdomain monitoring and Brand Trust for detecting lookalike domain abuse. Trusted by organizations including Save the Children and four of the UK's five magic circle law firms, Red Sift serves security and IT teams seeking to eliminate email-based cyber risk at scale.
